Risk factors for surgical site infection after instrumented fixation in spine trauma

Surgical site infection (SSI) represents a significant complication after instrumented fixation in spine trauma. Institutional practice changes have emphasized early fracture correction, shortened intraoperative times, early ambulation, and prompt nutritional supplementation. This retrospective study evaluates the senior author’s experience of instrumented spinal trauma SSI occurring at a single Level I trauma center over two equal and contiguous time periods, 2005–2007 (before nutritional supplementation was added to the institutional protocol) and 2008–2010 (after nutritional supplementation was added). This study assessed whether SSI varied depending on the primary surgical site and/or by the chosen approach. Lastly, the incidence of SSI among demographic and other clinical variables was evaluated. In total, 358 patients underwent an index procedure for spinal trauma correction. Fourteen patients developed a SSI requiring reoperation for an incidence of 4.0%.In assessing nutritional supplementation, the probability of infection tended to be lower in the supplemented group (3.7%) than the pre-supplement group (4.3%), but this did not reach significance. The difference in approach for the cervical spine was statistically significant (p = 0.045) with rates of infection via posterior approach at 8.1% and no infections via anterior approach. Presence of comorbidities (p = 0.03) and time to surgery >3 days (p = 0.006) were predictors of developing SSI. Benefit is shown from early surgical correction of spinal trauma patients in the reduction of postoperative SSI. Nutritional supplementation may provide a small reduction in infections in the spine trauma population.     

Impact of insurance status and race on receipt of treatment for acoustic neuroma: A national cancer database analysis

Acoustic neuroma (AN) management involves surgery, radiation, or observation. Previous studies have demonstrated that patient race and insurance status impact in-hospital morbidity/mortality following surgery; however the nationwide impact of these demographics on the receipt of each treatment modality has not been examined. The National Cancer Data Base (NCDB) from 2004 to 2013 identified AN patients. Multivariate analysis adjusted for several variables within each treatment modality, including patient age, race, sex, income, primary payer for care, tumor size, and medical comorbidities. Patients who were African-American (OR = 0.7; 95%CI = 0.5–0.9; p = 0.01), elderly (minimum age 65) (OR = 0.4; 95%CI = 0.4–0.6; p < 0.0001), on Medicare (OR = 0.6; 95% CI = 0.4–0.7; p = 0.0005), or treated at a community hospital (OR = 0.4; 95%CI = 0.2–0.7; p = 0.007) were less likely to receive surgery. Patients on Medicaid (OR = 1.2; 95%CI = 0.8–1.8; p = 0.04) or treated at an integrated network (OR = 1.2; 95%CI = 0.9–1.6; p = 0.0004) were more likely to receive surgery. Patients who were elderly (OR = 2.2; 95%CI = 1.7–2.9; p < 0.0001) or treated in a comprehensive cancer center (OR = 1.5; 95%CI = 1.3–1.9; p = 0.02) were more likely and Medicaid patients (OR = 0.8; 95%CI = 0.5–1.2; p = 0.04) were less likely to receive radiation. Patients who were elderly (OR = 2.2; 95%CI = 1.7–2.7; p < 0.0001), African-American (OR = 1.5; 95%CI = 1.1–2.0; p = 0.01), on Medicare (OR = 1.8; 95%CI = 1.4–2.3; p = 0.0003), or treated in a community hospital (OR = 3.0; 95%CI = 1.6–5.6; p = 0.0007) were more likely to receive observation. Patients on Medicaid (OR = 0.8; 95%CI = 0.5–1.2; p = 0.04) or treated in an integrated network (OR = 0.8; 95%CI = 0.6–1.0; p = 0.0001) were less likely to receive observation. African-American race, elderly age, and community hospital treatment triaged towards observation/away from surgery; age also triaged towards radiation. Conversely, integrated networks triaged towards surgery/away from observation; comprehensive cancer centers triaged towards radiation. Medicaid insurance triaged towards surgery/away from radiation/observation; this may be detrimental since lack of private insurance is a known risk factor for increased in-hospital postoperative morbidity.     

Surgery for lumbar disc herniation: Analysis of 500 consecutive patients treated in an interdisciplinary spine centre

Surgical removal of a symptomatic herniated lumbar disc is performed either with or without the support of a microscope. Up to the time of writing, the literature has reported similar clinical outcomes for the two procedures. Five hundred consecutive patients, operated upon for primary single-level lumbar disc herniation in our University Spine Center between 2003–2011, with (n = 275), or without (n = 225), the aid of a microscope were included. Data were retrospectively analyzed, comparing the primary endpoint of clinical outcome and the secondary endpoints of complications, surgical time and length of hospitalization. Clinical outcomes and reoperation rates were comparable in both groups. Surgical time was significantly shorter with a mean time of 47 minutes without use of the microscope compared to the mean time of 87 minutes (p < 0.001) with the use of the microscope. Mean length of hospitalization was shorter in those operated with the microscope (5.3 days) compared to those without (6.1 days, p = 0.004). There was no difference in rates of complications. Microdiscectomy versus open sequestrectomy and discectomy for surgical treatment of lumbar disc herniation is associated with similar clinical outcomes and reoperation rates. Open sequestrectomy is associated with shorter operation times. Microdiscectomy is associated with shorter hospitalization stays.     

Risk factors associated with short sleep duration among Chinese school-aged children

ObjectivesTo examine risk factors regarding short sleep duration among Chinese school-aged children.MethodsA random sample of 20,778 children aged around 5–11 years participated in a cross-sectional survey, which was conducted in eight cities of China in 2005. A parent-administered questionnaire was used to collect information on children’s sleep duration and possible related factors from eight domains. Short sleep duration was defined as total sleep duration <9 h per day.ResultsIn all, 28.3% of the sampled children slept <9 h per day. The multivariate logistic regression identified, after adjusting for demographic and socioeconomic variables, factors associated with short sleep duration: more television viewing during weekdays (OR = 1.21, p = 0.004), more frequent computer/internet using (OR = 1.17, p = 0.006), earlier school starting time (OR = 1.10, p = 0.020), more time on homework during weekdays (OR = 1.66, p < 0.001) and weekends (OR = 1.14, p = 0.001), poor bedtime hygiene (e.g., having drinks with caffeine after 6:00PM [OR = 1.22, p < 0.001], doing exciting activities during bedtime [OR = 1.16, p < 0.001], and irregular bedtime [OR = 1.55, p < 0.001]), and shorter sleep duration of parents (mother: OR = 1.31, p < 0.001 for sleep duration <6 h and OR = 1.24, p = 0.006 for 6–8 h; father: OR = 1.52, p < 0.001 for <6 h and OR = 1.19, p < 0.001 for 6–8 h).ConclusionsFactors associated with sleep duration covered multidimensional domains among school-aged children. Compared to sleep environments and chronic health problems, school schedules, lifestyle patterns, and parents’ sleep habits had greater impact on children’s sleep duration, indicating the existing chronic sleep loss in school children could be, at least partly, intervened by reducing the use of visual technologies, by changing the school schedules, by improving the sleep hygiene routine, and by regulating parents’ sleep habits.     

Why do young adolescents bully? Experience in Malaysian schools

IntroductionTo determine sociodemographic and psychological factors associated with bullying behavior among young adolescents in Malaysia.MethodsThis is a cross-sectional study of four hundred ten 12-year-old adolescents from seven randomly sampled schools in the Federal Territory of Kuala Lumpur, Malaysia. Sociodemographic features of the adolescents and their parents, bullying behavior (Malaysian Bullying Questionnaire), ADHD symptoms (Conners Rating Scales), and internalizing and externalizing behavior (Child Behaviour Checklist) were obtained from adolescents, parents and teachers, respectively.ResultsOnly male gender (OR = 7.071, p = 0.01*, CI = 1.642–30.446) was a significant sociodemographic factor among bullies. Predominantly hyperactive (OR = 2.285, p = 0.00*, CI = 1.507–3.467) and inattentive ADHD symptoms reported by teachers (OR = 1.829, p = 0.03*, CI = 1.060–3.154) and parents (OR = 1.709, p = 0.03*, CI = 1.046–2.793) were significant risk factors for bullying behavior while combined symptoms reported by young adolescents (OR = 0.729, p = 0.01*, CI = 0.580–0.915) and teachers (OR = 0.643, p = 0.02*, CI = 0.440–0.938) were protective against bullying behavior despite the influence of conduct behavior (OR = 3.160, p = 0.00*, CI = 1.600–6.241). Internalizing behavior, that is, withdrawn (OR = 0.653, p = 0.04*, CI = 0.436–0.977) and somatic complaints (OR = 0.619, p = 0.01*, CI = 0.430–0.889) significantly protect against bullying behavior.DiscussionsRecognizing factors associated with bullying behavior, in particular factors distinctive to the local population, facilitates in strategizing effective interventions for school bullying among young adolescents in Malaysian schools.     

Personal and workplace factors for the risk of low back pain among institutional caregivers of people with intellectual,autistic or multiple disabilities

The aims of the present study were to investigate the prevalence of LBP among institutional caregivers of people with intellectual, autistic or associated multiple disabilities and to examine the risk factors for LBP among this population. A cross-sectional, purposive sampling method was used to recruit into the study 1073 staff who were working in 15 disability welfare institutions. The survey materials included an introduction letter, an informed consent, and a structured questionnaire that queried the participant's demographic and working characteristics, healthy lifestyle, and previous and current LBP experiences. The present study results showed that 63.2% of the participants reported that they had LBP in the previous year. Many factors of the participants’ demographic characteristics (gender, BMI, and marital status), working conditions (years of working experience, weekly work days, labor-oriented work, and direct care staff), and health status (exercise habit, perceived health status, previous and more recent medication experience of musculoskeletal discomfort) associated with LBP occurrence were analyzed in univariate Chi-square analyses. Finally, multiple logistic regression analyses revealed that the factors of female gender (OR = 1.534, p = 0.039), being married (OR = 1.469, p = 0.027), being direct care staff (OR = 1.844, p = 0.025), having fair health status (OR = 1.518, p = 0.012), or previous (OR = 1.996, p < 0.001) and more recent (OR = 2.744, p < 0.001) medication experience of musculoskeletal discomfort were found to be more likely to have LBP than their counterparts. This study highlights that we should pay much closer attention to LBP risk factors and to plan necessary initiatives to avoid the progression of LBP in the workplace.     

A matched cohort comparison of cervical disc arthroplasty versus anterior cervical discectomy and fusion: Evaluating perioperative outcomes

ObjectiveCervical disc arthroplasty (CDA) is a recent alternative to anterior cervical discectomy and fusion (ACDF) in patients suffering cervical disc herniation and degeneration. To date, a systematic analysis of their comparative advantages and risks following elective surgery remains elusive.MethodsAdult patients undergoing elective CDA or ACDF were extracted from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database years 2011–2014. A total of 19,369 patients were matched 1:1 by age, sex, functional status, charlson comorbidity index, ASA classification, BMI classification, and number of vertebral levels operated on during surgery. This matching process led to a final sample of 588 subjects (294 CDA, 294 ACDF). Multivariable regression was performed for five outcome measures: operation time, early complications, reoperation rates, hospital length of stay (HLOS), and discharge destination. Mean differences (B), odds ratios (OR) and associated 95% confidence intervals (CI) are reported.ResultsCompared to ACDF, CDA was associated with decreased mean operation time (B = −18.78-min, 95% CI [−29.13, −8.42]; p < 0.001), decreased HLOS (B = −0.44-days [−0.77, −0.11]; p = 0.009), and increased likelihood of discharge to home (OR = 5.39 [1.14–25.43]; p = 0.033). No differences in reoperation rates and complications were found.ConclusionIn a matched cohort analysis, CDA performs comparably to ACDF and is associated with decreased operation time and HLOS, and increased likelihood of discharge to home, without differences in 30-day complications or reoperation rates. Future prospective studies are warranted.     

Percutaneous endoscopic lumbar discectomy for lumbar disc herniation

This study aims to compare the advantages and disadvantage of percutaneous endoscopic lumbar discectomy (PELD) and standard discectomy (SD) for the treatment of lumbar intervertebral disc herniation (LDH). We searched in MEDLINE, EMBASE, PubMed, Web of Science and Cochrane databases for relevant trials that compare PELD and SD for the treatment of LDH. The Cochrane Collaboration’s Revman 5.3 software was used for data analyses. This meta-analysis compiled 1301 cases from four random controlled trials and three retrospective studies. Compared with SD, PELD showed a shorter operative time (mean difference (MD) = −18.68, 95% confidence interval (CI): −24.92 to −12.43; p < 0.00001), less blood loss (MD = −64.88, 95% CI: −114.51 to −15.25, p < 0.0001), shorter hospital stay (MD = −3.51, 95% CI: −4.93 to −2.08, p < 0.00001), and shorter mean disability period (MD = −34.34, 95% CI: −53.90 to −14.77, p < 0.006). However, there were no significant differences in the visual analogue scale (VAS) scores at the final follow up (MD = −0.23, 95% CI: −0.53 to 0.07, p = 0.14), Macnab criteria at the final follow up (MD = 1.04, 95% CI: 0.72 to 1.50, p = 0.82), complications (RR = 0.76, 95% CI: 0.40 to 1.43, p = 0.39), recurrence rate (risk ratio (RR) = 1.00, 95% CI: 0.61 to 1.64, p = 1) and reoperation rate (RR = 1.40, 95% CI: 0.90 to 2.16, p = 0.13). In conclusion, despite PELD showing significant benefit in short term outcomes such as hospital course and mean disability period, similar clinical efficacy and long term outcomes were observed when compared to SD. Therefore, we suggest that PELD can be a feasible alternative to the conventional posterior approach for the LDH depending on surgeon preference and indication. High-quality randomized controlled trials with sufficient large sample sizes necessary further confirm these results.     

Mental health of caregivers of individuals with disabilities: Relation to Suicidal Ideation

ObjectiveThe mental health of caregivers of individuals with disabilities is frequently neglected. This study investigated mental health status and Suicidal Ideation (SI) among caregivers and examined the predictive factors for SI.MethodCaregivers of individuals with physical or mental disabilities in a tertiary hospital in southern Taiwan were recruited through snowball sampling. They were assessed by self-report questionnaires, consisting of the Taiwanese Depression Questionnaire and a subset of the three-item Chinese Health Questionnaire, to assess probable depression and common mental disorders (CMDs), with cutoff points of 19 and 3, respectively.ResultsAmong 255 caregivers, 32.9% had probable depression, 37.6% had probable CMDs, and 18.8% experienced SI. The level of SI was correlated with primary caregivers (p = 0.015), lack of support from co-caregivers (p = 0.023), caring for younger patients (p = 0.010), caring for patients with mental disability (p = 0.019) or catastrophic diseases (p = 0.005), and caregivers' probable depression (p < 0.001) and CMDs (p < 0.001). Regression analysis predicted the greatest SI among caregivers caring for younger patients (odds ratio [OR] = 0.98, p = 0.048) and for patients with catastrophic diseases (OR = 3.15, p = 0.008), as well as for caregivers with probable depression (OR = 3.90, p = 0.010) or CMDs (OR = 9.40, p < 0.001).ConclusionsWhen examining SI, clinicians should be aware of the mental health of caregivers who are responsible for people with disability. In particular, they should be vigilant regarding caregivers of individuals who are of younger age or have catastrophic diseases and regarding caregivers who exhibit probable depression and CMDs.     

Tryptophan hydroxylase 2 (TPH2) gene polymorphisms and psychiatric comorbidities in temporal lobe epilepsy

Psychiatric comorbidities are frequent in temporal lobe epilepsy (TLE). It is plausible that variance in serotonin-related genes is involved in the susceptibility of these associations. We report here the results on the association of tryptophan hydroxylase 2 (TPH2) gene polymorphisms with psychiatric comorbidities in TLE. A cohort study was conducted on 163 patients with TLE. We assessed the influence of the rs4570625 and rs17110747 polymorphisms in the TPH2 gene on psychiatric comorbidities in TLE. In patients with TLE, the presence of the T allele in the rs4570625 polymorphism was associated with psychotic disorders (OR = 6.28; 95% CI = 1.27–17.54; p = 0.02), while the presence of the A allele in the rs17110747 polymorphism was associated with alcohol abuse (OR = 20.33; 95% CI = 1.60–258.46; p = 0.02). Moreover, we identified male gender (OR = 11.24; 95% CI = 1.68–76.92; p = 0.01) and family history of psychiatric disorder (OR = 15.87; 95% CI = 2.46–100; p = 0.004) as factors also associated with alcohol abuse in TLE. Conversely, a family history of epilepsy was inversely associated with alcohol abuse (OR = 0.03; 95% CI = 0.001–0.60; p = 0.02). Tryptophan hydroxylase 2 gene allele variants might be risk factors for psychiatric conditions in TLE. More specifically, we observed that the T allele in the rs4570625 polymorphism was associated with psychotic disorders, and the A allele in the rs17110747 TPH2 polymorphism was associated with alcohol abuse in patients with TLE. We believe that this study may open new research venues on the influence of the serotonergic system associated with psychiatric comorbidities in epilepsy.     

The impact of negative treatment experiences on persistent refusal of antipsychotics

AimsWe investigate reasons for persistent medication refusal in schizophrenia spectrum disorders and test whether factors that speak for a rational decision, such as negative experiences with medication or low symptom distress predict medication refusal, even after taking differences in insight into account.MethodWe included 45 participants with schizophrenia spectrum disorders, of which 20 had refused antipsychotic medication for at least three months and assessed reasons for taking or not taking medication, labeling condition as mental disorder (“insight"), experiences with the previous treatments, symptoms and symptom distress, positive and negative consequences and experiences of psychosis, causal beliefs, therapeutic relationships with previous clinicians and attitudes towards medication.ResultsGroups did not differ in symptom severity but medication refusers reported significantly less insight, less satisfaction with their most-recent psychiatrist and with previous medication, and more negative beliefs about harmful effects of medication. They also felt less informed about medication. After controlling for insight, the perceived helpfulness of the previous treating psychiatrist (OR = 0.30, z = 5.58, p = 0.018) and of previous medication (OR = 0.27, z = 6.87, p = 0.009) and feeling insufficiently informed about medication (OR = 0.53, z = 3. 85, p = 0.050) significantly predicted medication discontinuation.ConclusionsBuilding rapport with patients with a different view of the nature of their condition and encouraging informed decisions on medication are likely to improve medication adherence. However, the findings also suggest that refusing medication after a phase of initial adherence is also the consequence of negative experiences with medication and could result from weighing the pros against the cons.     

Rs3761389 polymorphism in autoimmune regulator (AIRE) gene is associated with susceptibility of myasthenia gravis in Chinese patients

Polymorphism in autoimmune regulator (AIRE) gene is associated with various autoimmune disorders. Abnormal AIRE expression is associated with the development of myasthenia gravis (MG). We investigated the association of polymorphism in AIRE gene and the clinical features and severity of MG. The frequencies of alleles and genotypes were compared between 480 MG patients and 487 healthy controls, as well as among subgroups of MG patients. The frequencies of rs3761389 G allele in MG group (OR = 1.213, CI 95% 1.014–1.451, p = 0.035) and in mild (Oosterhuis score 0–2) subgroup (OR = 1.393, CI 95% 1.110–1.751, p = 0.004) were significantly higher than those in the control group. There were significant differences in the frequencies of rs3761389 genotypes (OR = 1.20, CI 95% 1.00–1.43, p = 0.046, log-additive model) and mild subgroup (OR = 1.32, CI 95% 1.03–1.69, p = 0.0058, log-additive model) compared with the control group. A Logistic regression analysis did not identify rs3761389 genotype as an independent risk factor to predict the severity of MG. This study provides the necessary preliminary data on the association with rs3761389 in AIRE gene with the susceptibility of MG, but not with the severity of MG.     

Suicide attempt in first-episode psychosis: A 7.4 year follow-up study

BackgroundIndividuals with first-episode psychosis demonstrate high rates of suicide attempt (SA).Aims1) To examine the prevalence of, and risk factors for, SA in a first-episode psychosis (FEP) cohort over a 7.4 year follow-up period. 2) To investigate differences between single versus multiple suicide attempters.MethodsThis study reports baseline and follow-up data from a naturalistic, prospective follow-up of 413 FEP patients treated at a specialist early psychosis centre. Assessments were conducted at treatment entry, initial symptom remission or stabilization, and long term follow-up. Binary logistic regression models were used to assess unadjusted and adjusted associations between early illness and sociodemographic characteristics and two outcome measures: any SA during follow-up; and multiple SAs.ResultsFollow-up data were available for 282 participants. Sixty-one (21.6%) made a suicide attempt over the follow-up period, including 12 successful suicides. The following baseline risk factors increased the risk of any SA: history of self-harm (OR = 4.27; p < 0.001), suicidal tendencies (OR = 2.30; p = 0.022), being depressed for > 50% of the initial psychotic episode (OR = 2.49; p = 0.045), and hopelessness (OR = 2.03; p = 0.030). History of problem alcohol use increased the risk of multiple SAs (OR = 4.43; 95% CI (1.05–18.7); p = 0.043).DiscussionThe prevalence of suicide attempt in this study exceeds reports from short-term FEP studies but is comparable to longer term follow-up studies, indicating that risk remains elevated for at least 7 years following commencement of treatment. The key predictor of future suicide attempt was previous self-harm, indicating that interventions for self-harm are required.     

Variant rs1906591 on chromosome 4q25 confers increased risk of cardioembolic stroke in Chinese patients

Ischemic stroke (IS) is a heterogeneous multifactorial disorder caused by both genetic and environmental factors. A genome-wide association study on stroke in Caucasians identified a variant on chromosome 4q25 that is significantly associated with IS, with the strongest risk for cardioembolic stroke (CES). The current study aims to investigate the association of the rs1906591 variant on 4q25 with IS through a case-control study in a Chinese Han population. A total of 712 IS patients and 774 control subjects were involved in the current research. Stroke subtyping was performed according to the Trial of Org 10172 in Acute Stroke Treatment criteria. The genotypes were determined using the SNaPshot technique. The association of the genotypes with the risk of IS was estimated using logistic regression analysis. The rs1906591 single nucleotide polymorphism variant was associated with the CES subtype in both recessive and additive models (recessive model: odds ratio [OR] = 2.58, 95% confidence interval [CI] 1.47–4.53, p = 0.001, adjusted OR = 2.71, 95% CI 1.48–4.96, p = 0.001; additive model: OR = 2.50, 95% CI 1.19–5.25, p = 0.015, adjusted OR = 2.83, 95% CI 1.24–6.50, p = 0.013). This result indicates that patients with the AA genotype have a higher rate of CES than other genotypes. However, the rs1906591 variant was not significantly associated with the overall incidence of stroke or other stroke subtypes. The rs1906591 variant is significantly associated with CES in the Chinese Han population, but not with other stroke subtypes.     

Sudden unexpected death in epilepsy: Knowledge and experience among U.S. and Canadian neurologists

ImportanceSudden unexpected death in epilepsy (SUDEP) is a common cause of mortality in patients with the disease, but it is unknown how neurologists disclose this risk when counseling patients.ObjectiveThis study aimed at examining SUDEP discussion practices of neurologists in the U.S. and Canada.DesignAn electronic, web-based survey was sent to 17,558 neurologists in the U.S. and Canada. Survey questions included frequency of SUDEP discussion, reasons for discussing/not discussing SUDEP, timing of SUDEP discussions, and perceived patient reactions. We examined factors that influence the frequency of SUDEP discussion and perceived patient response using multivariate logistic regression.ParticipantsThe participants of this study were neurologists who completed postgraduate training and devoted > 5% of their time to patient care.ResultsThere was a response rate of 9.3%; 1200 respondents met eligibility criteria and completed surveys. Only 6.8% of the respondents discussed SUDEP with nearly all (> 90% of the time) of their patients with epilepsy/caregivers, while 11.6% never discussed it. Factors that independently predicted whether SUDEP was discussed nearly all of the time were the following: number of patients with epilepsy seen annually (OR = 2.01, 95% CI = 1.20–3.37, p < 0.01) and if the respondent had a SUDEP case in the past 24 months (OR = 2.27, 95% CI = 1.37–3.66, p < 0.01). A majority of respondents (59.5%) reported that negative reactions were the most common response to a discussion of SUDEP. Having additional epilepsy/neurophysiology training was associated with an increased risk of a perceived negative response (OR = 1.36, 95% CI = 1.02–1.82, p = 0.038), while years in practice (OR = 0.85, 95% CI = 0.77–0.95, p < 0.005) and seeing both adults and children were associated with a decreased likelihood of negative response (OR = 0.15, 95% CI = 0.032–0.74, p = 0.02).ConclusionsU.S. and Canadian neurologists rarely discuss SUDEP with all patients with epilepsy/caregivers though discussions are more likely among neurologists who frequently see patients with epilepsy or had a recent SUDEP in their practice. Perceived negative reactions to SUDEP discussions are common but not universal; more experienced neurologists may be less likely to encounter negative reactions, suggesting that there may be ways to frame the discussion that minimizes patient/caregiver distress.     

Endoscopic endonasal approach to pituitary adenomas: Impact on adenohypophyseal function. Study of 231 cases

PurposeTo identify presurgical and surgical factors associated with the development of hypopituitarism and its recovery after endoscopic endonasal transsphenoidal (EET) resection of pituitary adenomas (PAs).MethodsRetrospective study of patients with PAs operated by the same neurosurgeon through an EET approach in two Spanish tertiary hospitals in ten years.Results242 pituitary surgeries performed in 231 patients were analyzed. In the 154 surgeries performed in 146 patients with non-functioning PAs (NFPAs), 46.8% (n = 72) presented presurgical hypopituitarism. After PAs resection, 41 of these (56.9%) normalized pituitary function and 11 of 82 patients with preoperative normal function (13.4%) developed new pituitary deficits. Patients with preoperative visual impairment (OR = 3.9, p = 0.046) and operated in the first four years of the neurosurgeon's learning curve (OR = 5.7, p = 0.016) presented a higher risk of developing postoperative hypopituitarism.Of the 88 surgeries in 85 patients with functioning PAs (FPAs), 23.9% presented presurgical hypopituitarism, and 47.6% of those recovered after surgery. 9% of the cases with preoperative normal function developed new pituitary deficit/s. Diabetic patients presented a higher risk of persistence of hypopituitarism (OR = 10.5, p = 0.024). Patients with presurgical visual impairment (OR = 30.0, p = 0.010) and PAs >3 cm (OR = 14.0, p = 0.027) had higher risk of developing new pituitary deficits.ConclusionApproximately 50% of patients with PAs and preoperative hypopituitarism recover pituitary function after EET surgery. 10% of patients with normal function develop new deficits. Patients with NFPAs with visual involvement and operated in the first four years of neurosurgeon's learning curve, and FPAs patients with presurgical visual impairment and tumor size >3 cm have a higher risk of postoperative hypopituitarism.     

The mediation effect of health literacy between subjective social status and depressive symptoms in patients with heart failure

ObjectivesDepressive symptoms are prevalent and cause adverse outcomes in heart failure. Previous studies have linked depressive symptoms with socioeconomic status. However, little is known about the mechanisms underlying this relationship. This study aimed to evaluate the association between socioeconomic status and depressive symptoms, and to examine whether access to healthcare, health literacy and social support mediated this relationship in patients with heart failure.MethodsCross-sectional design was used to study 321 patients with heart failure recruited from a general hospital. Demographics, clinical data, depressive symptoms, socioeconomic status (i.e., education, employment, income, and subjective social status), access to healthcare, health literacy, and social support were collected by patient interview, medical record review or questionnaires. A series of logistic regressions and linear regressions were conducted to examine mediation.ResultsThe mean age of patients with heart failure was 63.6 ± 10.6 years. Fifty-eight patients (18%) had depressive symptoms. Lower subjective social status (OR = 1.321, p = 0.012) and lower health literacy (OR = 1.065, p < 0.001) were separately associated with depressive symptoms. When subjective social status and health literacy were entered simultaneously, the relationship between subjective social status and depressive symptoms became non-significant (OR = 1.208, p = 0.113), demonstrating mediation. Additionally, lower social support was associated with depressive symptoms (OR = 1.062, p = 0.007).ConclusionsIn patients with heart failure, health literacy mediated the relationship between subjective social status and depressive symptoms. Lower social support was associated with depressive symptoms. Interventions should take these factors into account.     

Comparison of magnetic resonance angiography techniques to brain digital subtraction arteriography in the setting of mechanical thrombectomy: A non-inferiority study

IntroductionWe performed a non-inferiority study comparing magnetic resonance angiography (MRA) techniques including contrast-enhanced (CE) and time-of-flight (TOF) with brain digital subtraction arteriography (DSA) in localizing occlusion sites in acute ischemic stroke (AIS) with a prespecified inferiority margin taking into account thrombus migration.Materials and methodsHIBISCUS-STROKE (CoHort of Patients to Identify Biological and Imaging markerS of CardiovascUlar Outcomes in Stroke) includes large-vessel-occlusion (LVO) AIS treated with mechanical thrombectomy (MT) following brain magnetic resonance imaging (MRI) including both CE-MRA and TOF-MRA. Locations of arterial occlusions were assessed independently for both MRA techniques and compared to brain DSA findings. Number of patients needed was 48 patients to exclude a difference of more than 20%. Discrepancy factors were assessed using univariate general linear models analysis.ResultsThe study included 151 patients with a mean age of 67.6 ± 15.9 years. In all included patients, TOF-MRA and CE-MRA detected arterial occlusions, which were confirmed by brain DSA. For CE-MRA, 38 (25.17%) patients had discordant findings compared with brain DSA and 50 patients (33.11%) with TOF-MRA. The discordance factors were identical for both MRA techniques namely, tandem occlusions (OR = 1.29, P = 0.004 for CE-MRA and OR = 1.61, P < 0.001 for TOF-MRA), proximal internal carotid artery occlusions (OR = 1.30, P = 0.002 for CE-MRA and OR = 1.47, P < 0.001 for TOF-MRA) and time from MRI to MT (OR = 1.01, P = 0.01 for CE-MRA and OR = 1.01, P = 0.02 for TOF-MRA).ConclusionBoth MRA techniques are inferior to brain DSA in localizing arterial occlusions in LVO-AIS patients despite addressing the migratory nature of the thrombus.     

Predictors of recurrence after stent-assisted coil embolization of paraclinoid aneurysms

Stent-assisted coil embolization has been increasingly used to treat paraclinoid aneurysms. The study was aimed to evaluate safety and efficacy of stent-assisted coil embolization for paraclinoid aneurysms and explore the factors influencing the long-term outcomes. Under an institutional review board approved protocol, the clinical and angiographic data of 129 paraclinoid aneurysms in 120 patients (Male:Female = 36:84; median age, 52 years; range, 21–84) treated by stent-assisted coil embolization were reviewed retrospectively. Clinical status, aneurysmal morphology, treatment strategy and results were analyzed using Chi-squared tests in the univariate analysis and further analyzed using backward stepwise logistic regression. The univariate analysis indicated significance between the groups regarding hypertension, ruptured aneurysms, size, wide neck and immediate treatment results (P < 0.05). Multivariate logistic regression analysis found that ruptured aneurysms (odds ratio [OR] = 5.893, 95% confidence interval [CI], 1.512–23.054; p = 0.011), larger size (OR = 2.339; 95%CI, 1.148–4.781; p = 0.020) and hypertension (OR = 6.143; 95%CI, 1.560–24.183; p = 0.009) might be predictors of recurrence. Stent-assisted coil embolization of paraclinoid aneurysm has a risk of recurrence. Ruptured aneurysms, larger size and hypertension may be the risk factors for recurrence.     

Risk for osteopenia and osteoporosis in institution-dwelling individuals with intellectual and/or developmental disabilities

The purpose of this study was to investigate the prevalence of and contributing factors to osteopenia and osteoporosis among people with intellectual disabilities (ID) or/and developmental disabilities (DD) residing in a disability institution in Taiwan. The present study was conducted at one disability institution in Taiwan and recruited 184 institutionalized residents with ID and/or DD (115 men and 69 women aged 18–72 years) for analysis. For all residents with ID and/or DD, information was obtained about their age, gender, level of ID, BMI, and bone mineral density (BMD). BMD is a measurement of calcium levels in bones that can estimate the risk of osteoporosis and bone fractures. Bone tests were divided into three outcome categories based on their calcaneal BMD T-scores: Normal BMD, a T-score ≧ −1; Osteopenia, −2.5 ≦ T-score < −1; and Osteoporosis, a T-score < −2.5. The results revealed that 46.2% of cases were normal and that 27.7% and 26.1% of cases had osteopenia and osteoporosis, respectively. Multiple logistic regression analyses found that male gender (OR = 2.482, 95% CI = 1.04–5.93, p < 0.05), age ≧ 40 years (OR = 3.051, 95% CI = 1.07–8.69, p < 0.05) and being overweight/obese (OR = 0.395, 95% CI = 0.17–0.93, p < 0.05) were more likely to be associated with osteoporosis. Another model indicated that males (OR = 2.169, 95% CI = 1.12–4.19, p < 0.05) and those aged ≧ 40 years (OR = 3.026, 95% CI = 1.32–7, p < 0.01) tended to have an increased risk for osteopenia and osteoporosis. To improve the bone quality of individuals with ID or/and DD and to decrease the occurrence of osteopenia and osteoporosis, this study highlights that we should pay much attention to the potential risk factors for bone quality in these vulnerable populations.
