Prostate cancer detection upon transrectal ultrasound-guided biopsy in relation to digital rectal examination and prostate-specific antigen level: what to expect in the Chinese population?

We investigated the prostate cancer detection rates upon transrectal ultrasound (TRUS)-guided biopsy in relation to digital rectal examination (DRE) and prostate-specific antigen (PSA), and risk factors of prostate cancer detection in the Chinese population. Data from all consecutive Chinese men who underwent first TRUS-guided prostate biopsy from year 2000 to 2013 was retrieved from our database. The prostate cancer detection rates with reference to DRE finding and PSA level of < 4, 4–10, 10.1–20, 20.1–50 and > 50 ng ml⁻¹ were investigated. Multivariate logistic regression analyses were performed to investigate for potential risk factors of prostate cancer detection. A total of 2606 Chinese men were included. In patients with normal DRE, the cancer detection rates were 8.6%, 13.4%, 21.8%, 41.7% and 85.2% in patients with PSA < 4, 4–10, 10.1–20, 20.1–50 and > 50 ng ml⁻¹ respectively. In patients with abnormal DRE, the cancer detection rates were 12.4%, 30.2%, 52.7%, 80.6% and 96.4% in patients with PSA < 4, 4–10, 10.1–20, 20.1–50 and > 50 ng ml⁻¹ respectively. Older age, smaller prostate volume, larger number of biopsy cores, presence of abnormal DRE finding and higher PSA level were associated with increased risk of prostate cancer detection upon multivariate logistic regression analyses (P < 0.001). Chinese men appeared to have lower prostate cancer detection rates when compared to the Western population. Taking the different risk factors into account, an individualized approach to the decision of TRUS-guided biopsy can be adopted.     

Effects of Adult Romantic Attachment and Social Support on Resilience and Depression in Individuals with Spinal Cord Injuries

Background:

Spinal cord injury (SCI) can cause psychological consequences that negatively affect quality of life. It is increasingly recognized that factors such as resilience and social support may produce a buffering effect and are associated with improved health outcomes. However the influence of adult attachment style on an individual’s ability to utilize social support after SCI has not been examined.

Objective:

The purpose of this study was to examine relationships between adult romantic attachment perceived social support depression and resilience in individuals with SCI. In addition we evaluated potential mediating effects of social support and adult attachment on resilience and depression.

Methods:

Participants included 106 adults with SCI undergoing inpatient rehabilitation. Individuals completed measures of adult attachment (avoidance and anxiety) social support resilience and depression. Path analysis was performed to assess for presence of mediation effects.

Results:

When accounting for the smaller sample size support was found for the model (comparative fit index = .927 chi square = 7.86 P = .01 β = -0.25 standard error [SE] = -2.93 P < .05). The mediating effect of social support on the association between attachment avoidance and resilience was the only hypothesized mediating effect found to be significant (β = -0.25 SE = -2.93 P < .05).

Conclusion:

Results suggest that individuals with SCI with higher levels of attachment avoidance have lower perceived social support which relates to lower perceived resilience. Assessing attachment patterns during inpatient rehabilitation may allow therapists to intervene to provide greater support.     

Quality of life in bipolar and schizoaffective disorder — A naturalistic approach

Purpose

The aim of this study was to evaluate the health-related quality of life (HRQoL) in bipolar type I (BD I) and schizoaffective (SQA) patients during a 2-year period in a naturalistic study.

Methods

This study was based on the data generated by the Bipolar Comprehensive Outcome Study, a prospective, non-interventional, observational study of participants with BD I and SQA disorder. Mixed-Model Repeated Measures Analysis was used to analyze changes in the SF-36 and EQ-5D.

Results

Participants exhibited low health status at baseline with SF-36 mean scores of 46.7 ± 10.5 and 36.9 ± 12.9 (best imaginable health = 100, normal population ≈ 50) for physical and mental components, respectively. No significant differences were found between the ratings of the BD I and SQA patients on HRQoL. The SF-36 SMC improved significantly over 24 months although SPC scores remained consistent across the study. On the whole, the lowest SMC score was observed among the depressed patients (38.20), followed by the patients with a mixed state (39.01) and the manic patients (39.83).

Limitations

The observational design may have limited the causal relationships and the generalizability within the current findings.

Conclusions

HRQoL was significantly impaired in all stages of BD and SQA when compared to the general population. The impairment of HRQoL was most pronounced in the depressed state, followed by the mixed state and then the manic state. The euthymic patients showed the least impairment. In addition, patients showed a global improvement in their mental health satisfaction over the 2 years follow up period.     

Psychiatric morbidity in stroke patients attending a neurology clinic in Nigeria

Back ground

Stroke produces a wide range of mental and emotional disorders. Neuropsychiatric complications associated with stroke may have negative effects on the social functioning, overall quality of life and the recovery of motor functioning of stroke survivors.

Objective

To determine the prevalence and nature of psychiatric morbidity among stroke patients attending neurology outpatient clinic of the University of Ilorin Teaching Hospital (UITH), Ilorin-Nigeria.

Methods

All patients with stroke aged 18 years and above at an outpatient neurology clinic in Ilorin, Nigeria were assessed for mental and emotional disorders using the Schedule for Clinical Assessment in Neuropsychiatry (SCAN) over one year (March 2009 to February 2010).

Results

Overall prevalence of psychiatric morbidity was 36.0% (30/83) among 83 patients who constituted the study population. Specific diagnoses recorded were depression (19.2%), generalised anxiety disorder (9.6%), harmful alcohol use (2.4%); dementia, somatoform disorder, phobia and delusional disorder each had a prevalence of 1.2%. Clinical and sociodemographic variables were not significantly associated with psychiatric morbidity.

Conclusion

Psychiatric disorders are often associated with stroke. Identifying and treating stroke patients with these psychiatric co-morbidities could thus help to improve the overall quality of life of these patients.     

牛津单髁膝关节置换：长期结果

牛津膝置换是使用最广泛的膝关节单髁置换（UKR）。牛津膝在37年前开始应用,拥有一个全匹配的活动衬垫,因而磨损率非常低。牛津膝最主要的使用指征是膝关节前内侧骨关节炎,这种病人至少占所有需要行膝关节置换术患者的50％。由于这一系统的设计特点,传统UKR的反指征,如年龄、活动量、肥胖、髌股关节损害和软骨钙质沉着症等对于牛津膝均不是反指征。与全膝关节置换（TKR）相比,牛津膝提供更快的康复、更好的功能、更大的活动度和更好的术后满意度,发生并发症更少、程度更轻,病残率和死亡率更低。一个持续超过30年的研究显示在90％的病例中,牛津膝为患者终生提供了优或良的临床结果,且不需要翻修。在最近15年,牛津膝通过微创手术入路植入,涉及6000多例使用该入路牛津膝置换的9个研究报道显示,10年生存率约95％。在许多这样的研究中,医生们在拟行膝关节置换的患者中约50％使用了牛津单髁膝置换。     

Putonghua (modern standard Chinese)-speaking children with speech disorder

Developmental speech disorder affects up to 10% of the pre-school English-speaking population. However, speech disorder in Putonghua or Modern Standard Chinese (MSC)-speaking children has not been described. In this study the phonological systems of 33 Putonghua-speaking children with speech disorder were described. Quantitative measures (severity; inconsistency) as well as qualitative measures (phonetic and phonemic inventories; phonological processes) were presented. Of the 33 children, one child had articulation disorder, 18 had delayed phonological development, eight consistently used unusual error patterns, and six children's speech was characterized by inconsistency of production. The findings provided further cross-linguistic support for the 'four subgroup categorization system' (Dodd, 1993). The phonological systems of the Putonghua-speaking children with speech disorder were compared to those of normally developing children and those of children with speech disorder from other language backgrounds. Similar to normally developing children, Putonghua-speaking children with speech disorder were sensitive to the structure of the ambient language. They also shared the characteristics common to disordered children speaking other languages, such as persisting delayed processes, unusual error patterns, variability, restricted phonetic or phonemic inventory, and systematic sound or syllable preference.     

Lamotrigine in epilepsy,pregnancy and psychiatry – a drug for all seasons?

Lamotrigine has been demonstrated to be effective as both an antiepileptic drug and a mood stabiliser. For epilepsy it is less efficacious than valproate in primary generalised epilepsy, but it is comparable to some traditional drugs in partial epilepsy. In psychiatry it has significant advantages over other mood stabilisers for the treatment and prevention of depressive phases of bipolar illness, but not for the treatment of mania. It has a more benign adverse effect profile than older antiepileptic agents and is not a proven teratogen. Risk of adverse reactions is reduced by commencing treatment at a markedly reduced dose that is gradually increased.
