Risk and protective factors for mental disorders with onset in childhood/adolescence: An umbrella review of published meta-analyses of observational longitudinal studies.

The patho-etiology of mental disorders with onset in childhood or adolescence remains largely unknown. We conducted an umbrella review of meta-analyses (MAs) on environmental factors associated with mental disorders with onset in childhood/adolescence. We searched Pubmed-MEDLINE/EMBASE/PsycInfo databases, last search April 29th, 2020. Quality of MAs was measured with AMSTAR-2. Out of 6851 initial references, ten articles met inclusion criteria, providing 23 associations between 12 potential environmental factors and nine disorders (cases: 8884; N = 3,660,670). While almost half of the associations were nominally significant, none of them met criteria from either convincing or highly suggestive evidence. A single association was supported by suggestive evidence (maternal exposure to lithium or antipsychotics with neuromotor deficits), but it was affected by confounding by indication. Ten more associations had weak evidence, and 12 associations were not statistically significant. Quality of meta-analyses was rated as high in two, moderate in one, low in four, critically low in two, and not pertinent in one (individual participant data). Methodologically-sound research is needed in this field.

Efficacy of nonsurgical tigecycline pleurodesis for the management of hepatic hydrothorax in patients with liver cirrhosis.

Chemical pleurodesis is one of the therapeutic tools to control hepatic hydrothorax. Tetracycline and derivatives have been widely accepted as an effective and safe treatment for the purpose, but availability is the big concern. Tigecycline is an antibiotic derivative of tetracycline, which has demonstrated to be an effective pleurodesing agent in animal models. The aim of the study was to document two successful tigecycline pleurodesis in patients with decompensated liver cirrhosis, who were not candidates for liver transplantation. Both patients were undergoing palliative treatment for cirrhosis and developed massive pleural effusion on the right side. They underwent chemical pleurodesis in the first instance. Diagnostic thoracocentesis was done to rule out differentials and to confirm the clinical suspicion, following which, complete drainage of pleural fluids was achieved. Tigecycline of 3 mg/kg was instilled intrapleurally via the thoracic catheter, as per the protocol. The medical records and images were thoroughly reviewed. There was no recurrence of the effusion for at least 3 months, with no detected complications in the short- or long-term follow-up. In conclusion, pleurodesis with tigecycline seems to be effective and safe for the management of symptomatic hepatic hydrothorax and should therefore be promoted in the setting of liver cirrhosis at least for a short-term relief, especially in patients who do not meet the criteria for liver transplantation.

The utility of amylase and lipase as reliable predictive markers for functioning renal graft.

BACKGROUND: The aim of this study was to evaluate the utility of amylase and lipase as reliable predictive markers for functioning renal grafts, either short- or long-term. MATERIAL/METHODS: Serum amylase (Amyl), lipase, creatinine (Cr), creatinine clearance (Cr Cl) and 24-hr proteinuria (Prot) were studied in 190 kidney recipients. The correlation of these outcomes for each parameter was tested. Sensitivity and specificity of the variables were obtained in patients with graft failure (GF) and acute cellular rejection (ACR). RESULTS: Mean follow-up was 66.7 month. Amyl and lipase were elevated 67% vs. 45% in GF (N=23); 60% vs. 44% in ACR (N=42) patients and were inversely correlated with Cr Cl (p>.05). Lipase was notably superior to amylase and creatinine; the specificity of lipase (Amyl, Cr) was 87% (59%, 28%). Increases in amylase were more predictive in the presence of mild or moderate kidney failure (33% and 52%, respectively). However, the highest intensity of lipase elevation (39%) was in advanced kidney failure (Cr Cl <30 ml/min). CONCLUSIONS: Serum amylase and lipase should be used as markers monitoring graft function. For early detection of graft dysfunction, amylase seems to be superior to lipase.

Delivery in female kidney transplant recipients with hepatitis C virus infection: is it safe for mother and newborn?

The aim of this report is to evaluate whether pregnancy is a risk factor for poor outcome of infection with hepatitis C virus or for allograft deterioration among kidney transplant recipients. The first case was in a 41-year-old pregnant kidney transplant recipient with hypercreatinemia and a history of toxic hepatitis. The second case was treated with interferon before transplant. Tacrolimus-based immunosuppressive regimens were used during the pregnancies. Hypertension complicated both pregnancies, and the pregnancies ended with cesarean delivery at preterm and term with healthy but low-weight newborns. The first patient became positive for hepatitis C virus RNA after pregnancy without a flare in transaminase level. Antibodies to hepatitis C virus were negative in the newborns. In conclusion, pregnancy should be promoted for kidney recipients infected with hepatitis C virus who have stable graft and liver function.
