Emotion perception and executive functioning predict work status in euthymic bipolar disorder

Functional recovery, including return to work, in Bipolar Disorder (BD) lags behind clinical recovery and may be incomplete when acute mood symptoms have subsided. We examined impact of cognition on work status and underemployment in a sample of 156 Euthymic-BD and 143 controls (HC) who were divided into working/not working groups. Clinical, health, social support, and personality data were collected, and eight cognitive factors were derived from a battery of neuropsychological tests. The HC groups outperformed the BD groups on seven of eight cognitive factors. The working-BD group outperformed the not working-BD group on 4 cognitive factors composed of tasks of emotion processing and executive functioning including processing speed and set shifting. Emotion processing and executive tasks were predictive of BD unemployment, after accounting for number of mood episodes. Four cognitive factors accounted for a significant amount of the variance in work status among the BD participants. Results indicate that patients with BD who are unemployed/unable to work exhibit greater difficulties processing emotional information and on executive tasks that comprise a set shifting or interference resolution component as compared to those who are employed, independent of other factors. These cognitive and affective factors are suggested as targets for treatment and/or accommodations.     

Interfrontal encephalocele: a rare feature of forehead in hydrocephalic myelomeningocele patients. Clinical feature, probable mechanisms, and management

Objective

Myelomeningocele is a complex central nervous system malformation mostly associated with other neural and extraneural anomalies. A rare special feature of the forehead and skull was observed in myelomeningocele. Here, we present several patients with myelomeningocele, severe hydrocephalus, and interfrontal encephalocele accompanied by metopic suture widening and abnormally shaped frontal bones.

Methods

Five children with this feature were enrolled in this series. The age, sex, location of myelomeningocele sac, neurological deficits, hydrocephalus and history of shunt surgery, and follow-up period were evaluated.

Results

Patients were aged from 1 to 12 months (mean, 6 months). All patients were male. Most sacs were located in lumbar and lumbosacral areas. Neurological deficits varying from only sphincter problem to paraplegia were found in all patients. Hydrocephalus was found in all children that needed a shunt procedure. Asymptomatic Chiari malformation, interfrontal encephalocele, and corpus callosum agenesis were evident in five, five, and three patients, respectively.

Conclusion

Anterior fontanel anomalies known as interfrontal encephalocele associated with myelomeningocele have been reported before. The patients have an open metopic suture extending widely to the nasal radix producing hypertelorism accompanied by interfrontal herniation of frontal lobes. The associated hydrocephalus exaggerates the anomaly. Treatment of accompanying hydrocephalus is advised to decrease the severity of frontal lobe herniation. Some patients may need frontal bone reconstruction surgery to provide cosmetic correction at the place of the midline frontal bone defect.     

Evaluation of liver MRI examinations with two dosages of gadobenate dimeglumine: a blinded intra-individual study

Abdominal Radiology - There is discrepancy in the literature regarding the optimal dose of gadobenate for liver MRI. We evaluated the quality of liver MRIs performed in the same individual using...     

Haematological and biochemistry laboratory abnormalities associated with splenomegaly in asymptomatic adults in Masaka, Uganda: implications for HIV biomedical prevention trials

Objectives  To assess the degree of haematological and biochemistry abnormalities associated with splenomegaly in asymptomatic adults in order to determine whether they may be eligible for inclusion in HIV biomedical prevention trials.
Methods  Asymptomatic adults (50% women) aged 18–60  with splenomegaly (≥grade II by Hackett's classification) who agreed to provide blood and urine specimens for laboratory testing were invited to participate in a cross-sectional study. Volunteers who were menstruating, pregnant, infected with HIV, syphilis or Hepatitis B and C, or had significant clinical findings were excluded. Haematological and biochemistry laboratory evaluations were performed for enroled volunteers, and the results were compared to local reference ranges. The proportion of volunteers with out-of-range (OOR) values was estimated for each parameter. Linear regression models were fitted to investigate the association between grade of splenomegaly and laboratory values.
Results  The proportion of volunteers with OOR haematology values ranged from 4.5% (mean corpuscular volume) and 15% (CD4 cells) to 31% (basophils). Increasing spleen size was significantly associated with anaemia, thrombocytopenia and low CD4 count. OOR biochemistry values were found in about 10% of volunteers. Increasing spleen size was associated with reduced creatinine phosphokinase and creatinine (in men) and raised lactate dehydrogenase.
Conclusions  In areas with a high prevalence of splenomegaly, most asymptomatic individuals with this condition have haematology and biochemistry values that fall within the local reference ranges, and they could therefore be eligible for inclusion in HIV biomedical prevention trials. However, the effect of splenomegaly on certain parameters should be taken into account during interpretation of laboratory-based adverse events.     

Use of nail and oral pigmentation to determine ART eligibility among HIV‐infected Ugandan adults

Objectives To evaluate the use of grey/distal banded nails as an indicator of advanced immunosuppression, and thus eligibility for ART, in resource poor settings. Methods We tested whether grey/distal banded nails and/or oral pigmentation could be used to identify patients with low CD4 cell counts at two cut‐offs: <200 and <350 cells/μl in ART naive adults. Results Four hundred and three nail and oral cavities were photographed and assessed. Grey/distal banded nails and/or oral pigmentation were significantly associated with a CD4 cell count <200 cells/μl (P < 0.001), with a sensitivity of 66%, a specificity of 50% and a negative predictive value of 77%. However, there was no association when a CD4 cell count cut‐off of <350 cells/μl was used. Inter‐observer agreement (k 0.46) was fair/moderate. Conclusions While grey/distal banded nails and/or oral pigmentation are associated with low CD4 counts, the sensitivity and kappa score are too low for this method to be recommended as a tool to guide ART initiation; large number of individuals eligible for ART would be missed.     

Alcohol and HIV: a study among sexually active adults in rural southwest Uganda

OBJECTIVE: To investigate the association between alcohol consumption and HIV sero-positivity in a rural Ugandan population. METHODS: The adult population residing in a cluster of 15 neighbouring villages has been kept under epidemiological surveillance for HIV infection using annual censuses and sero-surveys since 1989. At the eighth annual survey all respondents were asked about their history of alcohol consumption, the sale of alcohol in their household, and other socio-demographic information. After informed consent, blood was drawn for HIV serology. RESULTS: Of the total adult population 3279 (60%) were interviewed; 48% were males; 905 (27%) had not started sexual activity and were excluded from further analysis. Of the remaining 2374, 8% were HIV infected, 57% had ever drunk alcohol, and 4% lived in households where alcohol was sold. Living in a household where alcohol was sold was associated with a history of having ever drunk alcohol (OR 2.9, 95% CI : 1.7-4.8). HIV prevalence among adults living in households selling alcohol was 15% compared with 8% among those living in households not selling alcohol (OR 2.0, 95% CI : 1.1-3.6). Individuals who had ever drunk alcohol experienced an HIV prevalence twice that of those who had never drunk, 10% versus 5% (OR 2.0, 95% CI : 1.5-2.8). This association remained after adjusting for potential confounders including sale of alcohol in the household and Muslim religion (OR 1.8, 95% CI : 1.2-2.7). Only age, marital status and having ever drunk alcohol independently predicted HIV sero-positivity in a logistic regression model. CONCLUSIONS: We have demonstrated an association between a history of alcohol consumption and being HIV sero-positive. This unexplored factor may explain in part the observed lower prevalence of HIV infection among Muslims. Public health campaigns need to stress the relationship between HIV and alcohol.
