Hepatic encephalopathy and health-related quality of life

The impact of overt hepatic encephalopathy on health-related quality of life is well defined, but it remains to be demonstrated how much the presence of minimal hepatic encephalopathy (MHE) might impair patients' perceived health status. MHE reduces cognitive abilities, with specific impairment in manual abilities, which can lead to a depressed mood that impairs perceived health status. Therefore, all subjects with cirrhosis should be systematically screened for MHE by validated tools. Early detection and treatment is mandatory to improve the quality of life of patients with advanced cirrhosis, their social isolation, and their daily lives.     

Variants in KITLG predispose to testicular germ cell cancer independently from spermatogenic function

Epidemiological data suggest an association and a common pathogenetic link between male infertility and testicular germ cell tumor (TGCT) development. Genome-wide studies identified that TGCT susceptibility is associated with KITLG (c-KIT ligand), which regulates the formation of primordial germ cells, from which TGCT is believed to arise and spermatogenesis develops. In this study, we analyzed the link between KITLG, TGCT, and spermatogenic disruption by performing an association study between the KITLG markers rs995030 and rs4471514 and 426 TGCT cases and 614 controls with normal and abnormal sperm count. We found that TGCT risk was increased more than twofold per copy of the major G allele and A allele in KITLG rs995030 and rs4471514 (odds ratio (OR)=2.38, 95% confidence interval (95% CI)=1.81-3.12; OR=2.43, 95% CI=1.86-3.17 respectively), and homozygotes for the risk allele had a sevenfold increased risk of TGCT. KITLG markers were strongly associated with seminoma subtype (per allele risk increased more than threefold, homozygote risk increased by 13- to 16-fold) and weakly with nonseminoma. KITLG markers were not associated with sperm production, as no difference was observed in men with normozoospermia and azoo-oligozoospermia, both in controls and in TGCT cases. In conclusion, this study provides evidence that KITLG variants are involved in TGCT development and they represent an independent and strong specific risk factor for TGCT independently from spermatogenic function. A shared genetic cause and a common pathogenetic link between TGCT development and impairment of spermatogenesis are not evident from this study.     

Sleep apnoea, anxiety, depression and somatoform pain: a community-based high-risk sample

Community-based studies that measure both psychiatric diagnoses and obstructive sleep apnoea (OSA) are lacking. This study reports current psychiatric disorders in community-dwelling adults at high risk for OSA identified by the Berlin Questionnaire. Furthermore, associations between OSA and current psychiatric disorders, unadjusted and adjusted for putative confounders, are reported. A subsample of the Akershus Sleep Apnoea Project consisting of 290 adults, aged 30-65 yrs, with positive Berlin Questionnaire screening underwent the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, version IV and polysomnography. Auxiliary analyses of depression are provided. The median apnoea/hypopnoea index score in the sample was 7.7 (interquartile range 2.4-22.2). Major depressive disorder, current anxiety and somatoform pain disorder were diagnosed in 12.4%, 14.8% and 19.3% of participants, respectively. At least one psychiatric disorder was diagnosed in 110 participants. The odds ratio of participants with OSA having a psychiatric disorder compared with participants without OSA was 0.54 (95% CI 0.33-0.88). A negative association did not exist among Berlin Questionnaire low-risk participants. In conclusion, more than one-third of participants in a community-based, Berlin Questionnaire high-risk sample were diagnosed with a psychiatric disorder. A negative association between OSA and psychiatric morbidity was found.     

Mass drug administration significantly reduces infection of <Emphasis Type="Italic">Schistosoma mansoni</Emphasis> and hookworm in school children in the national control program in Sierra Leone

Background  

The first-ever round of school-based mass drug administration (MDA) with praziquantel together with mebendazole targeting school-aged children in endemic districts was conducted in 2009 by the National Neglected Tropical Diseases Control Program. To evaluate the impact of the treatment regimen, a cross-sectional sentinel site survey was conducted 6 months post-MDA.     

Left ventricular assist device as bridge to recovery for anthracycline-induced terminal heart failure

?2012 Wiley Periodicals, Inc. Anthracycline treatments are hampered by dose-related cardiotoxicity, frequently leading to heart failure (HF) with a very poor prognosis. The authors report a case of a 19-year-old man developing HF after anthracycline treatment for Ewing sarcoma. Despite medical treatment, his condition deteriorated to terminal HF, leading to implantation of a mechanical left ventricular assist device (LVAD). His heart function recovered, allowing explantation of the device 14?months after implantation. Heart transplantation is often contraindicated in the first years after treatment for cancers, and LVAD as "bridge to recovery" may be warranted in similar patients.     

Corticosteroid Therapy, Vitamin D Status, and Inflammatory Cytokine Profile in the HIV-Tuberculosis Immune Reconstitution Inflammatory Syndrome

Background.?Tuberculosis-immune reconstitution inflammatory syndrome (TB-IRIS) in patients coinfected with human immunodeficiency virus (HIV) and tuberculosis starting antiretroviral therapy (ART) is associated with hypercytokinemia. As adjunctive corticosteroid therapy and vitamin D have immunomodulatory properties, we investigated the relationship between cytokine/chemokine profiles, corticosteroid use, and vitamin D deficiency in TB-IRIS patients. Methods.?Plasma from 39 TB-IRIS and 42 non-IRIS patients was collected during a prospective study of HIV-associated tuberculosis patients starting ART. In total, 26% of patients received corticosteroid (CTC) therapy pre-ART for severe tuberculosis. Concentrations of total 25-hydroxyvitamin D (25(OH)D) and 14 cytokines/chemokines were determined at ART initiation and 2 weeks later. Results.?Patients prescribed concurrent CTC had lower interferon γ (IFN-γ), IP-10, tumor necrosis factor (TNF), interleukin (IL)-6, IL-8, IL-10, IL-12p40, and IL-18 pre-ART (P?≤?.02). TB-IRIS presented at 12 days (median) of ART, irrespective of CTC use. In patients who developed TB-IRIS (not on CTC) IL-6, IL-8, IL-12p40, IL-18, IP-10, and TNF increased during 2 weeks (P?≤?.04) of ART. Vitamin D deficiency (total 25(OH)D <75?nmol/L) was highly prevalent (89%) at baseline. Although vitamin D deficiency at either baseline or 2 weeks was not associated with TB-IRIS, in those not on CTC the median 25(OH)D decreased during 2 weeks (P?=?.004) of ART. Severe vitamin D deficiency (total 25(OH)D <25?nmol/L) was associated with higher baseline TNF, IL-6, and IL-8 irrespective of IRIS status. Conclusions.?CTC modifies the inflammatory profile of those who develop TB-IRIS. The association between severe vitamin D deficiency and elevated proinflammatory cytokines support a study of vitamin D supplementation in HIV-TB co-infected patients starting ART.
