Predictors for treatment outcomes among patients with drug-susceptible tuberculosis in the Netherlands: a retrospective cohort study

ObjectivesWe evaluated treatment outcomes and predictors for poor treatment outcomes for tuberculosis (TB) among native- and foreign-born patients with drug-susceptible TB (DSTB) in the Netherlands.MethodsThis retrospective cohort study included adult patients with DSTB treated from 2005 to 2015 from a nationwide exhaustive registry. Predictors for unsuccessful treatment outcomes (default and failure) and TB-associated mortality were analysed using multivariate logistic regression.ResultsAmong 5674 identified cases, the cumulative incidence of unsuccessful treatment and mortality were 2.6% (n/N = 146/5674) and 2.0% (112/5674), respectively. Although most patients were foreign-born (71%; 4042/5674), no significant differences in these outcomes were observed between native- and foreign-born patients (p > 0.05). Significant predictors for unsuccessful treatment were aged 18–24 years (odds ratio (OR), 2.04; 95% CI 1.34–3.10), homelessness (OR, 2.56; 95% CI 1.16–5.63), prisoner status (OR, 5.39; 95% CI 2.90–10.05) and diabetes (OR, 2.02; 95% CI 1.03–3.97). Furthermore, predictors for mortality were aged 74–84 years (OR, 5.58; 95% CI 3.10–10.03) or ≥85 years (OR, 9.35, 95% CI 4.31–20.30), combined pulmonary and extra-pulmonary TB (OR, 4.97; 95% CI 1.42–17.41), central nervous system (OR, 120, 95% CI 34.43–418.54) or miliary TB (OR, 10.73, 95% CI 2.50–46.02), drug addiction (OR, 3.56; 95% CI 1.34–9.47) and renal insufficiency/dialysis (OR, 3.23; 95% CI 1.17–8.96).ConclusionsNative- and foreign-born patients exhibited similar TB treatment outcomes. To further reduce disease transmission and inhibit drug resistance, special attention should be given to high-risk patients.     

Participation in structured diabetes self-management education programs and its associations with self-management behaviour – a nationwide population-based study

ObjectiveTo evaluate the relationship between participation in structured diabetes self-management education programs (DSME) and self-management behaviour (SMB) in routine care.MethodsThe study included 864 ever- and 515 never-DSME participants from the population-based survey German Health Update (GEDA) 2014/2015. SMB and clinical care variables were: Following a diet plan, keeping a diabetes diary, holding a diabetes pass, self-monitoring of blood glucose (SMBG), foot self-examination (FSE), retinopathy screening, haemoglobin A1c (HbA1c) measurement and examination of the feet by clinicians (FEC). We conducted logistic regression analyses for association of DSME-participation with SMB, adjusting for various variables.ResultsDSME-participation was significantly associated with SMB including following a diet plan (OR 1.88 [95% CI 1.21–2.92]), keeping a diabetes journal (OR 3.83 [2.74–5.36]), holding a diabetes health passport (OR 6.11 [4.40–8.48]), SMBG (OR 2.96 [2.20–3.98]) and FSE (OR 2.64 [2.01–3.47]) as well as retinopathy screening (OR 3.30 [2.31–4.70]), HbA1c measurement (OR 2.58 [1.88–3.52]), and FEC (OR 3.68 [2.76–4.89]) after adjusting for confounders.ConclusionDSME-participation is associated with higher frequencies of various SMB and clinical care variables in routine care. Never-DSME attenders are more likely not to receive retinopathy screening, FEC and HbA1c measurements as recommended.Practice implicationsClinicians should refer diabetes patients to a DSME and ensure a regular follow up for never-DSME attenders.     

The efficacy of dapagliflozin for type 1 diabetes: a meta-analysis of randomized controlled studies

IntroductionThe efficacy of dapagliflozin for type 1 diabetes remains controversial. We conduct a systematic review and meta-analysis to explore the treatment efficacy of dapagliflozin versus placebo in patients with type 1 diabetes.MethodsWe have searched PubMed, EMbase, Web of science, EBSCO and Cochrane library databases through May 2019 for randomized controlled trials (RCTs) assessing the effect of dapagliflozin versus placebo for type 1 diabetes. This meta-analysis is performed using the random-effect model.ResultsSix RCTs are included in the meta-analysis. Overall, compared with control group for type 1 diabetes, dapagliflozin treatment shows favorable impact on glycated hemoglobin HbA1c (standard mean difference SMD=-3.93; 95% confidence interval CI =-4.44 to -3.48; P<0.00001), HbA1c reduction of ≥0.5% (risk ratio RR=1.98; 95% CI=1.65 to 2.39; P<0.00001), and fasting plasma glucose FPG (SMD=-0.93; 95% CI=-1.77 to -0.10; P=0.03). There is no statistical difference of hypoglycemia (RR=1.09; 95% CI=0.66 to 1.79; P=0.75) or adverse events (RR=1.07; 95% CI=0.96 to 1.20; P=0.20) between two groups, but the incidence of ketone-related events is higher than those in control group (RR=0.28; 95% CI=3.96 to 11.52; P=0.01).ConclusionsDapagliflozin treatment benefits to reduce HbA1c and FPG for type 1 diabetes.     

Sociodemographic,behavioral, and clinical factors associated with low atrial fibrillation knowledge among older adults with atrial fibrillation: The SAGE-AF study

BackgroundManagement of AF requires patient engagement in disease management which requires adequate knowledge about AF.ObjectiveTo identify the patient characteristics associated with low AF knowledge among older adults with AF.MethodsThe SAGE-AF cohort enrolled adults aged ≥65 diagnosed with AF in 2016?2018. Patient characteristics associated with low AF knowledge (<6/8 JAKQ items correct) were examined using multivariable adjusted logistic regression models.ResultsParticipants (N = 950) were on average 74 years old (SD: 6.7), 50 % female, and 87 % non-Hispanic white. The average JAKQ score was 68.7 (SD: 17.1), and 78 % had low AF knowledge. Participants aged ≥ 75 (OR: 1.55, 95 % CI: 1.03, 2.33), without a college degree (OR: 0.46, 95 % CI: 0.32, 0.65), cognitively impaired (OR: 1.72, 95 % CI: 1.15, 2.58), with a history of anxiety (OR: 1.76, 95 % CI: 1.09, 2.83), myocardial infarction (OR: 1.82, 95 % CI: 1.08, 3.07), and heart failure (OR: 1.84, 95 % CI: 1.16, 2.91) were more likely to have low AF knowledge.Practice implicationsCharacteristics available in the electronic medical record may identify patients at risk for low AF knowledge. Formal assessment of AF knowledge may identify areas of weakness and allow for targeted education.     

Sleep Duration and Glycemic Control in Patients with Diabetes Mellitus: Korea National Health and Nutrition Examination Survey 2007-2010

Short sleep duration has been reported to increase the risk of diabetes. However, the influence of sleep duration on glycemic control in diabetic patients has not been clarified. In this study we evaluated the association between sleep duration and glycemic control in diabetic patients. We analyzed the data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2007-2010. Sleep duration was classified into five groups: <6, 6, 7, 8, and ≥9 h/day. Fasting blood glucose and HbA1c showed a U-shaped trend according to sleep duration. Sleep duration of 7 h/day had the lowest HbA1c (7.26%) among the subjects (P=0.026). In the older age group (≥65 yr), a sleep duration of 6 h/day was associated with the lowest HbA1c (7.26%). The adjusted odds ratio (OR) with a 95% confidence interval (CI) of worse glycemic control (HbA1c ≥7.0%) in group of sleep duration of ≥9 h/day was 1.48 (1.04-2.13) compared with the group of 7 h/day. This relationship disappeared after adjusting duration of diabetes (OR, 1.38; 95% CI, 0.93-2.03). Our results suggest that sleep duration and glycemic control in diabetic patients has U-shaped relationship which was mainly affected by duration of diabetes.     

Clinical characteristics predicting early clinical failure after 72 h of antibiotic treatment in women with community-onset acute pyelonephritis: a prospective multicentre study

In patients with community-onset acute pyelonephritis (CO-APN), assessing the risk factors for poor clinical response after 72 h of antibiotic treatment (early clinical failure) is important. The objectives of this study were to define those risk factors, and to assess whether early clinical failure influences mortality and treatment outcomes. We prospectively collected the clinical and microbiological data of women with CO-APN in South Korea from March 2010 to February 2012. The numbers of cases in the early clinical success and early clinical failure groups were 840 (79.1%) and 222 (20.9%), respectively. Final clinical failure and mortality were higher in the early clinical failure group than in the early clinical success group (14.9% vs 2.3%, p <0.001; 6.8% vs 0.1%, p 0.001, respectively). In a multiple logistic regression model, the risk factors for early clinical failure among the total 1062 patients were diabetes mellitus (OR 1.5; 95% CI 1.1-2.1), chronic liver diseases (OR 3.3; 95% CI 1.6-6.7), malignancy (OR 2.2; 95% CI 1.1-4.4), Pitt score ≥2 (OR 2.5; 95% CI 1.6-3.8), presence of azotaemia (OR 1.8; 95% CI 1.2-2.7), white blood cell count ≥20 000/mm³ (OR 2.5; 95% CI 1.6-4.0), serum C-reactive protein level ≥20 mg/dL (OR 1.7; 95% CI 1.2-2.4), and history of antibiotic usage within the previous year (OR 1.5; 95% CI 1.1-2.2). Analysing the subgroup of 743 patients with CO-APN due to Enterobacteriaceae, fluoroquinolone resistance of the uropathogen was another factor associated with early clinical failure (OR 1.7; 95% CI 1.1-2.5). Simple variables of underlying diseases, previous antibiotic usage and initial laboratory test outcomes can be used to decide on the direction of treatment in CO-APN.     

Association analysis of vitamin D receptor gene polymorphisms in North England population with Type 2 diabetes mellitus

BackgroundNumerous diabetes susceptibility loci, include a region consisting vitamin D receptor gene found in chromosome 12q, have been known using genome wide screens.AimThe aim of present study is to probe the relationship between polymorphism of vitamin D receptor gene (single nucleotide polymorphisms) and type 2 diabetes mellitus (T2DM). Five hundred T2DM patients and 200 healthy subjects with normal HbA1c (≤ 5.0 %), fasting blood sugar (≤ 120 mg/dL) and random blood sugar (≤ 140 mg/dL) were enrolled.MetholodgyThe genotypes were found by polymerase chain reaction restriction fragment length polymorphism and DNA sequencing.Resultsrevealed that no considerable differences in frequencies of genotype and allele of the Bsm I and Fok I polymorphisms between healthy and patients in the North England (For Fok I: OR = 1.11, 95% CI: 0.72–1.12; for Bsm I: OR = 1.35, 95% CI: 0.79–1.98).ConclusionIt is recommended that both following polymorphisms of vitamin D receptor gene may not considerably add to the progression of T2DM in the North England.     

Cerebrovascular accidents differ between patients with atrial flutter and patients with atrial fibrillation

IntroductionFew studies have explored the potential impact of atrial flutter (AFl) on ischaemic stroke (IS) outcome. The aim of the present study was to compare the clinical course of IS in patients with AFl and patients with atrial fibrillation (AF).Material and methodsA retrospective analysis of patients consecutively admitted to a tertiary care centre between 2013 and 2015 due to IS or transient ischaemic attack with permanent AFl or permanent or persistent AF was performed.ResultsThe study groups consisted of 528 patients, including 490 (92.8%) patients with AF and 38 (7.2%) patients with AFl. The mean age and prestroke CHA2DS2-VASc scores were similar between the patients with AFl and those with AF. Most IS cases in the AF group were classified as cardioembolic strokes (74.9% vs. 39.5% in AFl, p < 0.01), and lacunar strokes were the most common in the AFl group (47.4% vs. 14.3% in AF, p < 0.01). The multivariable analysis revealed that the presence of AF (OR = 8.6, 95% CI: 1.2–57, p = 0.02), lacunar stroke (OR = 0.1, 95% CI: 0.03–0.31, p < 0.001), baseline Rankin scale score (OR = 16.6, 95% CI: 9.8–28), lack of prestroke therapeutic anticoagulation (OR = 6.1, 95% CI: 1.1–33), diabetes (OR = 2.9, 95% CI: 1.3–6.5, p < 0.01), chronic heart failure (OR = 14.2, 95% CI: 5.8–34, p < 0.001), and current smoking (OR = 0.92, 95% CI: 0.39–0.99, p < 0.01) were significantly associated with the stroke outcome.ConclusionsDisabling or fatal IS was observed less often in patients with AFl than in patients with AF. This finding can possibly be explained by the more frequent occurrence of lacunar strokes in the AFl group compared with that in the AF group.     

Systematic review with meta-analysis: Non-alcoholic fatty liver disease and the association with pregnancy outcomes

Background/AimsMaternal and fetal outcomes in pregnant patients with Non-alcoholic fatty liver disease (NAFLD) have been largely unexplored. To determine the level of evidence associated with maternal and fetal outcomes in pregnant women with NAFLD.MethodsWe conducted a comprehensive literature search. The studies included pregnant patients with a previous, current or subsequent diagnosis of NAFLD. We used a random-effects model using odds ratios (OR) with 95% confidence intervals (CI).ResultsTwenty-two studies, with 13,641 female NAFLD patients were reviewed. The results highlight that NAFLD patients had a statistically significant increased likelihood of baseline diabetes mellitus (OR, 6.00; 95% CI, 2.21–16.31; P<0.001; n=7), baseline Hypertension (OR, 3.75; 95% CI, 2.13–6.59; P<0.001; n=4), gestational hypertension (OR, 1.83; 95% CI, 1.03–3.26; P=0.041; n=2), and pre-eclampsia (OR, 2.43; 95% CI, 1.46–4.04; P=0.001; n=3). The odds for a past and current history of gestational diabetes mellitus were OR, 3.78; 95% CI, 2.21–6.44; P<0.001; n=5 and OR, 3.23; 95% CI, 1.97– 5.31; P<0.001; n=6, respectively. As for fetal outcomes, pregnant NAFLD patients were significantly more likely to have a premature birth (OR, 2.02; 95% CI, 1.44–2.85; P<0.001; n=4), large for gestational age birth (OR, 2.01; 95% CI, 1.72–2.37; P<0.001; n=2) or a history of prior miscarriage or abortion (OR, 1.15; 95% CI, 1.02–1.30; P=0.02; n=2). Egger’s regression revealed no evidence of publication bias (P>0.05).ConclusionsThis meta-analysis provides pooled evidence that NAFLD is associated with a substantial increase in maternal diabetic and hypertensive complications and multiple adverse fetal outcomes. This data is important for clinicians managing these patients before, during and after pregnancy.     

Development and validation of a prediction model for severe respiratory failure in hospitalized patients with SARS-CoV-2 infection: a multicentre cohort study (PREDI-CO study)

ObjectivesWe aimed to develop and validate a risk score to predict severe respiratory failure (SRF) among patients hospitalized with coronavirus disease-2019 (COVID-19).MethodsWe performed a multicentre cohort study among hospitalized (>24 hours) patients diagnosed with COVID-19 from 22 February to 3 April 2020, at 11 Italian hospitals. Patients were divided into derivation and validation cohorts according to random sorting of hospitals. SRF was assessed from admission to hospital discharge and was defined as: Spo₂ <93% with 100% Fio₂, respiratory rate >30 breaths/min or respiratory distress. Multivariable logistic regression models were built to identify predictors of SRF, β-coefficients were used to develop a risk score. Trial Registration NCT04316949.ResultsWe analysed 1113 patients (644 derivation, 469 validation cohort). Mean (±SD) age was 65.7 (±15) years, 704 (63.3%) were male. SRF occurred in 189/644 (29%) and 187/469 (40%) patients in the derivation and validation cohorts, respectively. At multivariate analysis, risk factors for SRF in the derivation cohort assessed at hospitalization were age ≥70 years (OR 2.74; 95% CI 1.66–4.50), obesity (OR 4.62; 95% CI 2.78–7.70), body temperature ≥38°C (OR 1.73; 95% CI 1.30–2.29), respiratory rate ≥22 breaths/min (OR 3.75; 95% CI 2.01–7.01), lymphocytes ≤900 cells/mm³ (OR 2.69; 95% CI 1.60–4.51), creatinine ≥1 mg/dL (OR 2.38; 95% CI 1.59–3.56), C-reactive protein ≥10 mg/dL (OR 5.91; 95% CI 4.88–7.17) and lactate dehydrogenase ≥350 IU/L (OR 2.39; 95% CI 1.11–5.11). Assigning points to each variable, an individual risk score (PREDI-CO score) was obtained. Area under the receiver-operator curve was 0.89 (0.86–0.92). At a score of >3, sensitivity, specificity, and positive and negative predictive values were 71.6% (65%–79%), 89.1% (86%–92%), 74% (67%–80%) and 89% (85%–91%), respectively. PREDI-CO score showed similar prognostic ability in the validation cohort: area under the receiver-operator curve 0.85 (0.81–0.88). At a score of >3, sensitivity, specificity, and positive and negative predictive values were 80% (73%–85%), 76% (70%–81%), 69% (60%–74%) and 85% (80%–89%), respectively.ConclusionPREDI-CO score can be useful to allocate resources and prioritize treatments during the COVID-19 pandemic.     

Herpes simplex virus type 2 among mobile pastoralists in northwestern Namibia

Background: Although herpes simplex virus type 2 (HSV-2) epidemiology has been described for many western and/or urban populations, disease burden has not been characterized for remote, non-western, under treated populations, where patterns of risk and vulnerability may be very different.

Aims: To understand demographic, behavioural and geographic influences on risk for HSV-2 in a population of mobile, rural pastoralists in northwestern Namibia.

Subjects and methods: The authors conducted a cross-sectional survey of reproductively aged adults (n?=?445) across 28 villages in Kaokoveld, Namibia. All participants completed a questionnaire of demographic data, ecological interactions and sexual behaviour, and a rapid test specific for HSV-2.

Results: HSV-2 status was significantly associated with being female (OR?=?3.1, 95% CI?=?2.00, 4.71), increasing age (men: OR?=?7.5, 95% CI?=?2.67, 20.85; women: OR?=?6.2, 95% CI?=?2.48, 15.50) and with higher wealth among men (OR?=?5.1, 95% CI?=?1.98, 13.09).

Conclusions: Higher risk among women can be explained, in part, by local hygiene practices and a preference for “dry” sex. There was considerable variation in prevalence by region, which appears to be linked to geographic remoteness. Culturally contextualized epidemiologic studies of remote, vulnerable populations can provide essential information for limiting the introduction and spread of new infections.     

Risk Factors of Unplanned Readmission after Anterior Cervical Discectomy and Fusion: A Systematic Review and Meta-Analysis

PurposeWith an increasing number of anterior cervical discectomy and fusion (ACDF) being conducted for degenerative cervical disc disease, there is a rising interest in the related quality of management and healthcare costs. Unplanned readmission after ACDF affects both the quality of management and medical expenses. This meta-analysis was performed to evaluate the risk factors of unplanned readmission after ACDF to improve the quality of management and prevent increase in healthcare costs.Materials and MethodsWe searched the databases of PubMed, EMBASE, Web of Science, and Cochrane Library to identify eligible studies using the searching terms, “readmission” and “ACDF.” A total of 10 studies were included.ResultsAmong the demographic risk factors, older age [weighted mean difference (WMD), 3.93; 95% confidence interval (CI), 2.30–5.56; p<0.001], male [odds ratio (OR), 1.23; 95% CI, 1.10–1.36; p<0.001], and private insurance (OR, 0.34; 95% CI, 0.17–0.69; p<0.001) were significantly associated with unplanned readmission. Among patient characteristics, hypertension (HTN) (OR, 2.14; 95% CI, 1.41–3.25; p<0.001), diabetes mellitus (DM) (OR, 1.59; 95% CI, 1.20–2.11; p=0.001), coronary artery disease (CAD) (OR, 2.87; 95% CI, 2.13–3.86; p<0.001), American Society of Anesthesiologists (ASA) physical status grade >2 (OR, 2.13; 95% CI, 1.68–2.72; p<0.001), and anxiety and depression (OR, 1.39; 95% CI, 1.29–1.51; p<0.001) were significantly associated with unplanned readmission. Among the perioperative factors, pulmonary complications (OR, 22.52; 95% CI, 7.21–70.41; p<0.001) was significantly associated with unplanned readmission.ConclusionMale, older age, HTN, DM, CAD, ASA grade >2, anxiety and depression, pulmonary complications were significantly associated with an increased occurrence of unplanned readmission after ACDF.     

Predictors of patient adherence to COPD self-management exacerbation action plans

ObjectiveIdentifying patient characteristics predicting categories of patient adherence to Chronic Obstructive Pulmonary Disease (COPD) exacerbation action plans.MethodsData were obtained from self-treatment intervention groups of two COPD self-management trials. Patients with ≥1 exacerbation and/or ≥1 self-initiated prednisolone course during one-year follow-up were included. Optimal treatment was defined as ‘self-initiating prednisolone treatment ≤2 days from the onset of a COPD exacerbation’. Predictors of adherence categories were identified by multinomial logistic regression analysis using patient characteristics.Results145 COPD patients were included and allocated to four adherence categories: ‘optimal treatment’ (26.2 %), ‘sub optimal treatment’ (11.7 %), ‘significant delay or no treatment’ (31.7 %), or ‘treatment outside the actual exacerbation period’ (30.3 %). One unit increase in baseline dyspnoea score (mMRC scale 0–4) increased the risk of ‘significant delay or no treatment’ (OR 1.64 (95 % CI 1.07?2.50)). Cardiac comorbidity showed a borderline significant increased risk of ‘treatment outside the actual exacerbation period’ (OR 2.40 (95 % CI 0.98?5.85)).ConclusionMore severe dyspnoea and cardiac comorbidity may lower adherence to COPD exacerbation action plans.Practice implicationsTailored self-management support with more focus on dyspnoea and cardiac disease symptoms may help patients to better act upon increased exacerbation symptoms and improve adherence to COPD exacerbation action plans.     

Prevalence of overweight/obesity and its associated factors among a sample of Moroccan type 2 diabetes patients

BackgroundObesity constitutes a major risk factor for the development of diabetes, and has been linked with poor glycaemic control among type 2 diabetic patients.AimsThis study examines the prevalence of overweight/obesity and associated factors in type 2 diabetic patients in the Beni-Mellal Khenifra region in Morocco.MethodsA questionnaire-based cross-sectional study was conducted in 2017 among 975 diabetes patients attending primary health centres. Demographic and clinical data were collected through face-to-face interviews. Anthropometric measurements, including body weight, height and waist circumference, were taken using standardized techniques and calibrated equipment.ResultsThe prevalence of overweight was 40.4%, the general obesity was 28.8% and the abdominal obesity was 73.7%. Using multivariate analysis, we noted that the general obesity was associated with female sex (AOR= 3,004, 95% CI: 1.761–5.104, P<0.001), increased age (AOR=2.192, 95% CI: 1.116–4.307, P<0.023) and good glycaemic control (AOR=1.594, 95% CI: 1.056–2.407, P=0.027), whereas abdominal obesity was associated wih female sex (AOR=2.654, 95% CI: 1.507–4.671, P<0.001) and insulin treatment (AOR=2.927, 95% CI: 1.031–8.757, P=0.048).ConclusionOverweight, general obesity and abdominal obesity were high among participants, especially among women. Taken together, these findings urge the implementation of a roadmap for this diabetic subpopulation to have a new lifestyle.     

Right ventricular dysfunction and pulmonary hypertension in COVID-19: a meta-analysis of prevalence and its association with clinical outcome

IntroductionRapid spread of COVID-19 has caused detrimental effects globally. Involvement of the ACE2 receptor has identified COVID-19 as a multi-organ disease. Preliminary studies have provided evidence that cardiac involvement, including right ventricular dysfunction (RVD) and pulmonary hypertension (PH), were found in COVID-19 cases, even in the non-advanced stage. This meta-analysis aims to analyze the prevalence of RVD and PH, and their association with COVID-19 clinical outcome.Material and methodsA systematic data search was conducted through PubMed, medRxiv, ProQuest, Science Direct, and Scopus databases using constructed keywords based on MeSH terms. Any outcomes regarding mortality, severity, ICU admission, and mechanical ventilation usage were analyzed using RevMan v.5.4 and Stata v.16.ResultsA total of 16 eligible studies (1,728 patients) were included. Pooled prevalence of RVD in COVID-19 was 19% (95% CI: 13–25%), and PH was 22% (95% CI: 14–31%). RVD was associated with increased mortality (OR = 2.98 (95% CI: 1.50–5.89), p = 0.002), severity (OR = 3.61 (95% CI: 2.05–6.35), p < 0.001), ICU admission (OR = 1.70 (95% CI: 1.12–2.56), p = 0.01), and mechanical ventilation (MV) usage (OR = 1.60 (95% CI: 1.14–2.25), p = 0.007). PH was also associated with increased mortality (OR = 5.42 (95% CI: 2.66–11.060, p < 0.001), severity (OR = 5.74 (95% CI: 2.28–14.49), p < 0.001), and ICU admission (OR = 12.83 (95% CI: 3.55–46.41), p < 0.001).ConclusionsRVD and PH were prevalent in COVID-19 and associated with mortality, severity, ICU admission, and MV usage in COVID-19 patients. Bedside echocardiography examination could be considered as a novel risk stratification tool in COVID-19.     

Nursing consultations and control of diabetes in general practice: a retrospective observational study

Background

Diabetes affects around 3.6 million people in the UK. Previous research found that general practices employing more nurses delivered better diabetes care, but did not include data on individual patient characteristics or consultations received.

Aim

To examine whether the proportion of consultations with patients with diabetes provided by nurses in GP practices is associated with control of diabetes measured by levels of glycated haemoglobin (HbA1c).

Design and setting

A retrospective observational study using consultation records from 319 649 patients with diabetes from 471 UK general practices from 2002 to 2011.

Method

Hierarchical multilevel models to examine associations between proportion of consultations undertaken by nurses and attaining HbA1c targets over time, controlling for case-mix and practice level factors.

Results

The proportion of consultations with nurses has increased by 20% since 2002 but patients with diabetes made fewer consultations per year in 2011 compared with 2002 (11.6 versus 16.0). Glycaemic control has improved and was more uniformly achieved in 2011 than 2002. Practices in which nurses provide a higher proportion of consultations perform no differently to those where nurse input is lower (lowest versus highest nurse contact tertile odds ratio [OR] [confidence interval {95% CI}]: HbA1c ≤53 mmol/mol (7%) 2002, 1.04 [95% CI = 0.87 to 1.25] and 2011, 0.95 [95% CI = 0.87 to 1.03]; HbA1c ≤86 mmol/mol (10%) 2002, 0.97 [95% CI = 0.73 to 1.29] and 2011, 0.95 [95% CI = 0.86 to 1.04]).

Conclusion

Practices that primarily use GPs to deliver diabetes care could release significant resources with no adverse effect by switching their services towards nurse-led care.     

Prevalence of parental death among young people in South Africa and risk for HIV infection

OBJECTIVES: This study estimated the prevalence and sociodemographic characteristics of young people in South Africa who have experienced parental death and examined associations between parental death and young people's HIV status and sexual behaviors. DESIGN AND METHODS: Data were from a cross-sectional nationally representative household survey of 11,904 15- to 24-year-old South Africans. Surveys included items on sexual behavior and family composition, and oral fluid samples were collected to test for HIV status. RESULTS: The prevalence of parental death was 27.3% overall: 22.4% reported a father deceased, 7.9% reported a mother deceased, and 3.0% reported both parents deceased. Parental death was disproportionately associated with black ethnicity, impoverished household living conditions, lack of an adult guardian in the home, and not completing compulsory education levels. Controlling for sociodemographic factors, parental death among female participants was significantly associated with HIV-positive status (odds ratio [OR] = 1.25, 95% confidence interval [CI]: 1.08 to 1.44), ever having had oral sex (OR = 1.23, 95% CI: 1.02 to 1.49), ever having had vaginal sex (OR = 1.38, 95% CI: 1.19 to 1.60), and having more than 1 sex partner during the past year (OR = 1.33, 95% CI: 1.07 to 1.64). Among male participants, parental death was significantly associated with ever having had vaginal sex (OR = 1.19, 95% CI: 1.04 to 1.36) and having unprotected sex at the last sexual episode (OR = 1.23, 95% CI: 1.07 to 1.42). CONCLUSIONS: More than one quarter of young South Africans have experienced parental death. Death of a parent is associated with young female South Africans' HIV status and sexual behaviors among young female and male South Africans. HIV prevention interventions are necessary to address the specific needs of young South Africans who have experienced parental death.     

Socio-demographic determinants of neonatal mortality in Algeria according to MICS4 data (2012–2013)

BackgroundNeonatal mortality remains a public health problem in developing countries, including Algeria. Information on this indicator makes it possible to assess government efforts to improve the living conditions of target populations.ObjectivesThis study aims to identify some determinants associated with this mortality from data of multiple indicator cluster survey conducted in Algeria in 2012–2013 (mics 4).MethodsA retrospective case-control study including 1047 cases and 1041 controls. From a logistic regression model, we appreciated the role of different factors, socio-demographic, economic and geographic (Mother''s age, level of education, wealth index, area of residence) in newborn survival.ResultsThe main factors associated with neonatal mortality were rural residence (p<0.01; OR= 1.3; CI 1.08–1.54), South geographical area (p<0.05; OR=1.5; CI 1.18–1.84), low education level of mother (p<0.01; OR= 2.10; CI 1.35– 3.29), early age of maternal procreation (p<0.001; OR=4.34; CI 2.19– 14.40), the birth rank “7 and over” (<0.01; OR = 1.57; CI 1.13 – 2.44) and the two lowest wealth indices (p <0.001; OR = 2; 1.45–2.62 and p <0.01; OR = 1.66; CI 1.23–2.26).ConclusionIn addition to the various reproductive health strategies already adopted by the authorities for health promotion and family planning, action should be taken to evaluate their implementation with sustained assistance for disadvantaged people and in risk areas.     

Risk of waning humoral responses after inactivated or subunit recombinant SARS-CoV-2 vaccination in patients with chronic diseases: Findings from a prospective observational study in China

Heterogeneity of antibody responses has been reported in SARS-CoV-2 vaccination recipients with underlying diseases. We investigated the impact of the presence of comorbidities on the humoral response to SARS-CoV-2 vaccination in patients with chronic disease (PWCD) and assessed the effect of the number of comorbidities on the humoral response to vaccination. In this study, neutralizing antibodies (NAbs) and IgG antibodies against the receptor-binding domain (RBD-IgG) were monitored following a full-course vaccination. In total, 1400 PWCD (82.7%, inactivated vaccines; 17.3%, subunit recombinant vaccine) and 245 healthy controls (65.7% inactivated vaccines, 34.3% subunit recombinant vaccine) vaccinated with inactivated or subunit recombinant SARS-CoV-2 vaccines, were included. The seroconversion and antibody levels of the NAbs and RBD-IgG were different in the PWCD group compared with those in the control group. Chronic hepatitis B (odds ratio [OR]: 0.65; 95% confidence interval [CI]: 0.46–0.93), cancer (OR: 0.65; 95% CI: 0.42–0.99), and diabetes (OR: 0.50; 95% CI: 0.28–0.89) were associated with lower seroconversion of NAbs. Chronic kidney disease (OR: 0.29; 95% CI: 0.11–0.76), cancer (OR: 0.38; 95% CI: 0.23–0.62), and diabetes (OR: 0.37; 95% CI: 0.20–0.69) were associated with lower seroconversion of RBD-IgG. Only the presence of autoimmune disease showed significantly lower NAbs and RBD-IgG titers. Patients with most types of chronic diseases showed similar responses to the controls, but humoral responses were still significantly associated with the presence of ≥2 coexisting diseases. Our study suggested that humoral responses following SARS-CoV-2 vaccination are impaired in patients with certain chronic diseases.     

Management of type 2 diabetes with multiple oral hypoglycaemic agents or insulin in primary care: retrospective cohort study

BACKGROUND: Intensive glycaemic control can reduce the risk of microvascular complications in people with type 2 diabetes. AIM: To examine the extent of monitoring and glycaemic control of patients with type 2 diabetes prescribed oral agents and/or insulin, and to investigate transition to insulin. DESIGN OF STUDY: Retrospective cohort study. SETTING: A total of 154 general practices in the UK contributing to the DIN-LINK database between 1995 and 2005. METHOD: People with type 2 diabetes were identified using Read codes and prescribing data. Outcome measures were: glycaemic monitoring and control on multiple oral agents and/or insulin, and transition to insulin. RESULTS: A total of 14 824 people with type 2 diabetes were prescribed multiple oral agents concurrently, of whom 5064 (34.16%) had haemoglobin A(1c) (HbA(1c)) assessments 6 months before and following initiation of their last oral therapy. Mean HbA(1c) before therapy was 9.07%, which dropped to 8.16% following therapy (mean difference 0.91%, 95% confidence interval [CI] = 0.86 to 0.95, P <0.0001). Of the patients with HbA(1c) assessments, 3153 (62.26%) had evidence of poor glycaemic control following therapy. Median time to insulin for patients prescribed multiple oral agents was 7.7 years (95% CI = 7.4 to 8.5 years); 1513 people began insulin during the study and had HbA(1c) assessments 6 months before and following insulin. Mean HbA(1c) before insulin was 9.85% (standard deviation [SD] 1.96%) which decreased by 1.34%, (95% CI = 1.24% to 1.44%) following therapy, but 1110 people (73.36%) still had HbA(1c) > or =7.5%. CONCLUSION: Many people with type 2 diabetes received inadequate monitoring and had poor glycaemic control. Intensive management is required to reduce the risk of microvascular complications.
