Non-alcoholic fatty liver disease and obesity: the role of the gut bacteria.

Non-alcoholic fatty-liver disease (NAFLD) is now considered one of the leading causes of liver disease worldwide and is associated with metabolic syndrome and obesity. There are several factors contributing to the disease state. Recent research suggests that the intestinal microbiota (IM) and bacterial products may play a role through several mechanisms which include increased energy uptake, intestinal permeability and chronic inflammation. In addition to diet and exercise, treatment options targeting the IM are being investigated and include the use of pre-, pro- and synbiotics as well as the possibility of fecal microbial transfers. This literature review explores the relationship between NAFLD and the IM as well as highlight new IM treatment options that may become available in the near future.

Kratom: a dangerous player in the opioid crisis.

Kratom use as a herbal supplement is on the rise in the United States, with reported medical outcomes and lethal effects suggesting a public health threat. Even though the Drug Enforcement Administration has included kratom on its drugs of concern list and the FDA has published a press release to identify it as an opioid with a potential for abuse, its therapeutic and side effects are still not well defined in the literature. Here, we present a case of a 32-year-old man with a history of kratom use who became acutely ill with a brief prodromal illness, followed by jaundice and elevated liver enzymes showing a cholestatic picture, and his successful treatment. In this case, we emphasize the need for awareness of kratom exposure as a key contributor in the expansion of the opioid crisis, with therapeutic benefits earned at the expense of potentially lethal side effects.

A rare case of peritonitis due to Brevundimonas vesicularis.

Healthcare associated infections due to gram negative bacilli are a major concern among healthcare institutions. While Pseudomonas and Escherichia coli species are known major organisms; other lesser known species can also cause primary infection. We present a case of peritonitis in a patient on a peritoneal dialysis regimen due to Brevundimonas vesicularis.

Missense Mutation in the Ligand-Binding Domain of the Horse Androgen Receptor Gene in a Thoroughbred Family with Inherited 64,XY (SRY+) Disorder of Sex Development.

Disorders of sex development (DSD) have long been documented in domestic animal species including horses. However, there is only a single report of an androgen receptor (AR) mutation causative of such a DSD syndrome in a horse pedigree. Here, we present a new familial AR mutation in horses. A missense mutation (c.2042G>C) at AR exon 4 explains the segregation of the DSD in a Thoroughbred horse pedigree. The mutation, expected to affect the ligand-binding domain of the AR protein, led to complete androgen insensitivity of 64,XY SRY+, testicular DSD individuals. Additionally, the design of a PCR-RFLP technique provided an accurate molecular test for the identification of horses carrying the mutation.
