The treatment of benzodiazepine withdrawal is difficult, and the search continues for substances that can reduce craving and the risk of relapse. Here, we report three cases of benzodiazepine addicts with histories of unsuccessful withdrawal attempts who experienced marked reductions in craving and improved relapse prognoses under add-on administration of agomelatine. These cases demonstrate a possible area of use for the antidepressant agomelatine in the treatment of benzodiazepine withdrawal and addiction. The extent to which this effect is due to the anti-craving effects of agomelatine, or its profile of receptor activation, should be further investigated in larger clinical and experimental studies.

OBJECTIVES: The cholera outbreak in Yemen has become the largest in the recent history of cholera records, having reached more than 1.4 million cases since it started in late 2016. This study aimed to identify risk factors for cholera in this outbreak.METHODS: A case-control study was conducted in Aden in 2018 to investigate risk factors for cholera in this still-ongoing outbreak. In total, 59 cholera cases and 118 community controls were studied.RESULTS: The following risk factors were associated with being a cholera case in the bivariate analysis: a history of travelling and having had visitors from outside Aden Province; eating outside the house; not washing fruit, vegetables, and khat (a local herbal stimulant) before consumption; using common-source water; and not using chlorine or soap in the household. In the multivariate analysis, not washing khat and the use of common-source water remained significant risk factors for being a cholera case.CONCLUSIONS: Behavioural factors and unsafe water appear to be the major risk factors in the recent cholera outbreak in Yemen. In order to reduce the risk of cholera, hygiene practices for washing khat and vegetables and the use and accessibility of safe drinking water should be promoted at the community level.

BACKGROUNDThe purposes of this study were to confirm the changes in myocardial collagen level after left ventricular assist device (LVAD) support in dilated cardiomyopathy (DCM), find the relation between these changes and prognosis, and test a practical method to assess the level of myocardial collagen.
METHODSLeft ventricular samples were collected from DCM patients with different prognosis (transplanted group n = 8, weaning group n = 10) at the time when the LVADs were implanted and again during cardiac transplantation (n = 8). The level of neutral salt soluble collagen (NSC) and acid soluble collagen (ASC) was measured by Sircol collagen assay, and that of total collagen and insoluble collagen (ISC) by quantification of hydroxyproline (Hyp). Serum samples were collected from a portion of these patients (transplanted group, n = 6; weaning group n = 7) at the time the LVADs were implanted, 1 month after implantation and on explantation. Circulating concentration of carboxy-terminal propeptide of type I procollagen (P I CP), amino-terminal propeptide of type I procollagen (P I NP), amino-terminal propeptide of type III procollagen (P III NP) and type I collagen telopeptide (I CTP) were measured by the equilibrium type radioimmunoassay.
RESULTSBefore LVAD implantation the level of NSC and ISC in the weaning group was higher but ASC in the transplanted group was lower than in the controls (P < 0.05). After LVAD support, the level of total collagen was higher, but ASC was also lower in the transplanted group than in the controls (P < 0.05). In comparison of the pre- and post-LVAD subgroups of the transplanted and weaning groups, all collagen fraction levels before LVAD implantation were lower in the transplanted group than in the weaning group (P < 0.05); but this difference disappeared after LVAD support. Comparison of the pre- and post-LVAD subgroups of the transplanted group showed increased level of NSC and total collagen after LVAD support. The changes of serum peptide concentration showed that P III NP increased constantly in the transplanted group, but P I CP and P I NP increased in the weaning group after LVAD implantation.
CONCLUSIONSThe changes in myocardial collagen level as a sign of myocardial interstitial remodeling in DCM are not involved with total collagen but involved with collagen fractions, and they are related to prognosis. The changes of myocardial collagen content and serum procollagen peptide after LVAD support can be regarded as an expression of the reverse of maladaptive myocardial interstitial remodeling.
