Background: On January 9, 2015, in a rural town in Mozambique, over 230 people became sick and 75 died from an illness linked to drinking pombe, a traditional alcoholic beverage. Methods: An investigation was conducted to identify cases and determine the cause of the outbreak. A case was defined as any resident of Chitima who developed any new or unexplained neurologic, gastrointestinal, or cardiovascular symptom from January 9 at 6:00 a.m. through January 12. We conducted medical record reviews; healthcare worker and community surveys; anthropological and toxicological investigations of local medicinal plants and commercial pesticides; and laboratory testing of the suspect and control pombe...

BACKGROUND: In the diagnosis of brain death (BD), computed tomography angiography (CTA) results in some cases show intracranial filling, leading to diagnostic confusion. Because cerebral circulatory arrest commences at the capillary level, we hypothesized that computed tomography perfusion (CTP) would be a more sensitive approach than CTA; therefore, the aim of the study was to compare the sensitivities of CTP and CTA in the diagnosis of BD. MATERIAL AND METHODS: Whole brain CTP was performed in patients in the intensive care unit diagnosed with BD and CTA was derived from CTP datasets...

BACKGROUND: Recent research indicates a favourable influence of postmenopausal hormone therapy (HT) if initiated early, but not late, on subclinical atherosclerosis. However, the clinical relevance of timing of HT initiation for hard end points such as stroke remains to be determined. Further, no previous research has considered the timing of initiation of HT in relation to haemorrhagic stroke risk. The importance of the route of administration, type, active ingredient, and duration of HT for stroke risk is also unclear...

BACKGROUND: The introduction of specific cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors significantly improved progression-free survival in hormone receptor-positive metastatic breast cancer. CDK 4/6 inhibitors induce cell cycle arrest via liberating the tumor suppressor retinoblastoma protein from CDK4/6 inhibitory effect. Preliminary studies suggested an increase in the hematological toxicities which might affect the quality of life in such palliative setting. METHODS: We searched PubMed, ASCO, ESMO and San Antonio meeting databases for randomized phase II/III trials in metastatic breast cancer receiving CDK4/6 inhibitors with safety data provided on the incidence of hematological adverse effects...
