Outcomes of cardiac arrest hospitalizations in patients with obesity with versus without prior bariatric surgery status:A nationwide propensity-matched analysis.

Introduction: Prior bariatric surgery (PBS) status in obese patients is thought to curtail the risk of cardiovascular events, but its role in change of outcomes of patients with obesity developing new acute cardiac events such as cardiac arrests (CA) remains largely unknown. Methods: Hospitalizations among adult patients with obesity and CA were identified retrospectively using the National Inpatient Sample (2015 October-2017 December). Propensity-matched analysis (1:1) was performed for sociodemographic/hospital characteristics to identify two cohorts, with (PBS+) or without (PBS-) status. The primary endpoint was in-hospital mortality, and the secondary endpoint was healthcare resource utilization. Results: Both cohorts (n = 1275 each), had patients with comparable age (mean 58 years), with a higher frequency of white (>70 %), females (>60 %), and Medicare enrollees (>40 %). PBS + cohort had lower rates of diabetes (27.8 % vs 36.1 %), hyperlipidemia (33.7 % vs 48.6 %), renal failure (17.3 % vs 22.0 %), chronic pulmonary disease (11.8 % vs 21.2 %) and higher rates of anemias (18.4 % vs 12.2 %), liver disease (5.1 % vs 2.4 %) and alcohol abuse (6.7 % vs 2.4 %) than PBS- cohort (p < 0.05). All-cause mortality (46.3 % vs 45.1 %, p = 0.551) was comparable between the two cohorts. The PBS + cohort was less often transferred routinely (p<0.001) but had a shorter hospital stay (p<0.001) with equivalent hospital charges compared to the PBS- cohort. Conclusions: The PBS status (regardless of chronology) did not increase survival in CA admissions among patients with obesity. Preventive measures are necessary to manage enduring cardiovascular disease risk factors that may limit the advantages of surgery for patients with obesity and aggravate the worse outcomes of future cardiac events.

Joubert Syndrome: A Molar Tooth Sign in Disguise.

Joubert syndrome (JS) is a rare genetic ciliopathy characterized by the aplasia or malformation of the midbrain and or hindbrain structures. It usually manifests during the early stages with nonspecific neurological symptoms that progress to involve multiple systems. Its presentation similarity to other neurological disorders makes the diagnosis difficult, hence causing a delay in treatment and worse prognosis due to complications. If undiagnosed during childhood, it often presents during adolescence with the most common complication of acute kidney injury due to nephronophthisis. Here, we present a case of JS in late adolescence with renal complications and other neurological abnormalities. We aim to emphasize the importance of its early diagnosis by physicians in childhood to prevent further complications. It also highlights the possible diagnostic value and significance of brain imaging in the early stages when only mild mental retardation signs may be the only clues.

Secondary Postpartum Hemorrhage Presenting With Bombay Blood Group: A Case Report.

Bombay blood group is a rare blood group. Due to its rarity and limitations for transfusions, it is often challenging to manage individuals with Bombay groups in emergencies. Here, we present a case of a 26-year-old woman with the Bombay blood group who had premature rupture of membranes at the 39th week of pregnancy while delivering a male child vaginally. The patient suffered from postpartum hemorrhage due to retention of the placenta and needed an immediate blood transfusion. During the antenatal screening, she was noted to have the O-positive blood group. Cross-matching of her blood was incompatible with O-positive blood and was identified as the Bombay blood group after having tested for anti-H antibodies. The patient underwent transfusion by identifying individuals with the O-positive Bombay blood group. As a result of this, we emphasize the diagnosis and identification of the individuals with the Bombay blood group and make blood available especially in medical emergencies.
