Non-overweight depressed patients who respond to antidepressant treatment have a higher risk of later metabolic syndrome: findings from the METADAP cohort.

BACKGROUND: Major depressive disorder (MDD) is a complex disorder with a significant public health burden. Depression remission is often associated with weight gain, a major risk factor for metabolic syndrome (MetS). The primary objective of our study was to assess prospectively the impact of response to antidepressant treatment on developing MetS in a sample of MDD patients with a current major depressive episode (MDE) and who are newly initiating their treatment. METHODS: In the 6-month prospective METADAP cohort, non-overweight patients, body mass index <25 kg/m2, with MDD and a current MDE were assessed for treatment response after 3 months of treatment, and incidence of MetS after 3 and 6 months of treatment. Outcome variables were MetS, number of MetS criteria, and each MetS criterion (high waist circumference, high blood pressure, high triglyceridemia, low high-density lipoprotein-cholesterolemia, and high fasting plasma glucose). RESULTS: In total, 98/169 patients (58%) responded to treatment after 3 months. A total of 2.7% (1/38) developed MetS out of which 12.7% (10/79) (p value < 0.001) had responded to treatment after 3 months. The fixed-effect regression models showed that those who responded to treatment after 3 months of follow-up had an 8.6 times higher odds of developing MetS (odds ratio = 8.58, 95% confidence interval 3.89-18.93, p value < 0.001). CONCLUSION: Compared to non-responders, non-overweight patients who responded to treatment after 3 months of antidepressant treatment had a significantly higher risk of developing MetS during the 6 months of treatment. Psychiatrists and nurses should closely monitor the metabolic profile of their patients, especially those who respond to treatment.

Nitric Oxide Synthase activity in major depressive episodes before and after antidepressant treatment: Results of a large case-control treatment study.

BACKGROUND: Nitric oxide synthase (NOS) activity, an enzyme potentially involved in the major depressive episodes (MDE), could be indirectly measured by the L-Citrulline/L-Arginine ratio (L-Cit/L-Arg). The aim of this study was: (1) to compare the NOS activity of patients with a MDE to that of healthy controls (HC); (2) to assess its change after antidepressant treatment. METHODS: A total of 460 patients with a current MDE in a context of major depressive disorder (MDD) were compared to 895 HC for NOS activity (L-Cit/L-Arg plasma ratio). L-Arg and L-Cit plasma levels were measured using a MS-based liquid chromatography method. Depressed patients were assessed at baseline, and after 3 and 6 months of antidepressant treatment for depression severity and clinical response. RESULTS: Depressed patients had a lower NOS activity than HC at baseline [0.31 ± 0.09 v. 0.38 ± 0.12; 95% confidence interval (CI) -0.084 to -0.062, p < 0.0001]. Lower NOS activity at baseline predicted a higher response rate [odds ratio (OR) = 29.20; 95% CI 1.58-536.37; p = 0.023]. NOS activity in depressed patients increased significantly up to 0.34 ± 0.08 after antidepressant treatment (Est = 0.0034; 95% CI 0.0002-0.0067; p = 0.03). CONCLUSIONS: Depressed patients have a decreased NOS activity that improves after antidepressant treatment and predicts drug response. NOS activity may be a promising biomarker for MDE in a context of MDD.

Simple antireflux technique for the cologastric anastomosis: complementary step in retrosternal colon interposition procedure.

Gastrocolic reflux is a troublesome symptom causing repeated aspiration or chocking in patients underwent retrosternal colon interposition. Various techniques were described to avoid such complication, however, they entail complicated technique that may jeopardize the viability of the graft or cause obstructing symptoms. A simple antireflux procedure is described here alleviating this problem. Over the last 7 years, 87 patients had gastrocolic antireflux procedure for cologastric anastomosis; 75 patients as a primary procedure (group 1) and 12 patients as a secondary procedure treating symptomatic reflux (group 2). The technique entails the creation of cologastric angle after finishing the cologastric anastomosis by applying three stitches between the colon and the stomach, thus tucking the colon to the stomach for 3-4 cm. Gastrocolic reflux was evaluated clinically and radiologically 3 months postoperatively. In group 1, three cases (4%) suffered symptomatic gastrocolic reflux, and seven cases (9.3%) had radiological asymptomatic mild reflux, while all patients in group 2 had complete alleviation of their symptoms with gastrogram showing no reflux. Gastrocolic reflux can be treated simply by creation of cologastric angle; however, controlled trial is needed to confirm its effectiveness in comparison to other described techniques.

Validation of the Arabic Rowland Universal Dementia Assessment Scale (A-RUDAS) in elderly with mild and moderate dementia.

OBJECTIVES: Validated screening tests for dementia in Arabic are lacking. Given the low levels of education among elderly in the Middle East and North Africa region, the commonly used screening instrument, the Mini Mental State Examination, is not best suited. Alternatively, the Rowland Universal Dementia Assessment Scale (RUDAS) was especially designed to minimize the effects of cultural learning and education. The aim of this study was to validate the RUDAS in the Arabic language (A-RUDAS), evaluate its ability to screen for mild and moderate dementia, and assess the effect of education, sex, age, depression, and recruitment site on its performance. METHODS: A-RUDAS was administered to 232 elderly aged ≥65 years recruited from the communities, community-based primary care clinics, and hospital-based specialist clinics. Of these, 136 had normal cognition, and 96 had dementia. Clinicians diagnosed dementia according to the Diagnostic and Statistical Manual of Mental Disorders fourth edition (DSM-IV) criteria. Interviewers, blind to the cognitive status of participants, administered A-RUDAS. The psychometric properties of A-RUDAS were examined for three cutoffs. RESULTS: At the cutoff of ≤22, A-RUDAS exhibited good sensitivity (83%) and specificity (85%) with an area under the receiver operating characteristic curve of 83.95%. Adjusting for age, sex, education, depression, and recruitment site, A-RUDAS score demonstrated a high level of accuracy in screening for mild and moderate dementia against DSM-IV diagnosis. CONCLUSION: The A-RUDAS is proposed for dementia screening in clinical practice and in research in Arabic-speaking populations with an optimal cutoff of ≤22.

Topical mitomycin C can effectively alleviate dysphagia in children with long-segment caustic esophageal strictures.

Caustic ingestion in children and the resulting long esophageal strictures are usually difficult to be managed, and eventually, esophageal replacement was required for cases refractory to frequent dilatation sessions. Topical mitomycin C (MMC) application has been used recently to improve the results of endoscopic dilatation for short esophageal strictures. The study aims to assess the role of MMC application in management of long-segment caustic esophageal strictures. From January 2009 to June December 2013, patients presented with long caustic esophageal stricture (>3 cm in length) were included in this study and subjected to topical MMC application after endoscopic esophageal dilatation on multiple sessions. Regular follow-up and re-evaluation were done. A dysphagia score was used for close follow-up clinically; verification was done radiologically and endoscopically. During the specified follow-up period, 21 patients with long caustic esophageal stricture were subjected to topical MMC application sessions. Clinical, radiological, and endoscopic resolution of strictures occurred in 18 patients (85.7% cure rate). Number of dilatation sessions to achieve resolution of dysphagia was (n = 14.3 ± 5.7) with application of mitomycin two to six times. There was no recurrence in short- and mid-term follow-up. No complications were encountered related to topical MMC application. MMC is a promising agent in management of long-segment caustic esophageal strictures. Long-term follow-up is needed to prove its efficacy and to evaluate potential long-term side-effects of MMC application.

Characteristics of physicians practising in Lebanon: a survey.

The last survey of the characteristics of the Lebanese physician workforce, in 1998, raised concerns about the oversupply of physicians and gaps in capacity building. This telephone survey in 2007 of a stratified random sample of physicians describes the demographic, educational and practice characteristics of 546 physicians practising in Lebanon. A majority of the physicians had graduated from an eastern European or a Lebanese medical school, in the1980s or 1990s, and had postgraduate training in a non-primary care specialty, in a western or eastern European country. The greatest numbers were practising solo, in a medical or surgical specialty, in a private hospital and in an urban setting. The average proportion of work time spent in teaching and research were 2.4% and 1.2% respectively. The findings suggest that less emphasis should be placed on training in specialty care compared with primary care/general practice and future policies should aim to attract physicians to rural areas.
