Coronary artery bypass grafting bundled payment proposal will have significant financial impact on hospitals

Objectives

The Centers for Medicare and Medicaid Services plans to institute a 5-year trial of bundled payments for coronary artery bypass grafting through 90 days after discharge. To investigate the impact, we reviewed actual inpatient costs for patients undergoing bypass surgery relative to the target price.

Prevalence and Associated Factors of Depression Among Post-Stroke Patients in Bangladesh

To assess the prevalence of depression and its associated factors among patients with stroke in Bangladesh. We conducted a cross-sectional study among 164 post-stroke patients attending two hospitals in Dhaka city between January and June 2011. Depression was measured using the Hamilton Depression Rating Scale. Factors associated with depression were analyzed using multivariate logistic regression. Results: The prevalence of depression was 70 and 32 % had severe depression. The mean ± sd age of the participants was 58.91 ± 7.03 years. Multivariate regression analysis revealed that factors significantly associated with depression were living in a joint family (OR = 13.5, 95 % CI = 1.3–145.7, p = 0.032), those unable to perform daily activities by themselves (OR = 14.9, 95 % CI = 2.0–108.1, p = 0.008) and those with comorbid dysphasia (OR = 9.5, 95 % CI = 1.0–86.9, p = 0.046) and hypertension (OR = 5.2, 95 % CI = 2.3–15.4, p = 0.012). Depression is a significant health problem among post-stroke patients in Bangladesh. This leads to careful management of depression for social support to achieve better patient outcome.     

Uncovering obsessive-compulsive disorder risk genes in a pediatric cohort by high-resolution analysis of copy number variation

Background

Obsessive-compulsive disorder (OCD) is a heterogeneous neuropsychiatric condition, thought to have a significant genetic component. When onset occurs in childhood, affected individuals generally exhibit different characteristics from adult-onset OCD, including higher prevalence in males and increased heritability. Since neuropsychiatric conditions are associated with copy number variations (CNVs), we considered their potential role in the etiology of OCD.

Methods

We genotyped 307 unrelated pediatric probands with idiopathic OCD (including 174 that were part of complete parent-child trios) and compared their genotypes with those of 3861 population controls, to identify rare CNVs (<0.5 % frequency) of at least 15 kb in size that might contribute to OCD.

Results

We uncovered de novo CNVs in 4/174 probands (2.3 %). Our case cohort was enriched for CNVs in genes that encode targets of the fragile X mental retardation protein (nominal p?=?1.85?×?10^?03; FDR=0.09), similar to previous findings in autism and schizophrenia. These results also identified deletions or duplications of exons in genes involved in neuronal migration (ASTN2), synapse formation (NLGN1 and PTPRD), and postsynaptic scaffolding (DLGAP1 and DLGAP2), which may be relevant to the pathogenesis of OCD. Four cases had CNVs involving known genomic disorder loci (1q21.1-21.2, 15q11.2-q13.1, 16p13.11, and 17p12). Further, we identified BTBD9 as a candidate gene for OCD. We also sequenced exomes of ten “CNV positive” trios and identified in one an additional plausibly relevant mutation: a 13 bp exonic deletion in DRD4.

Conclusions

Our findings suggest that rare CNVs may contribute to the etiology of OCD.

     

Renin-angiotensin system blockade does not attenuate abdominal aortic aneurysm growth,rupture rate,or perioperative mortality after elective repair

Objective

The objective of this study was to summarize the literature regarding the effects of renin-angiotensin system blockade (RASB) using angiotensin-converting enzyme inhibitors (ACEis) or angiotensin receptor blockers (ARBs) on human abdominal aortic aneurysm (AAA) growth, rupture, and perioperative mortality.

Laparoscopic Nissen Fundoplication Plus Mid-gastric Plication for Treatment of Obese Patients with Gastroesophageal Reflux Disease

Background

Gastroesophageal reflux disease (GERD) is commonly associated with obesity, and its surgical management is debatable.

Objective

The objective of this study was to prove the safety and feasibility of laparoscopic Nissen’s fundoplication (LNF) combined with mid-gastric plication (MGP) for treatment of obese patients with GERD.

Methods

LNF combined with MGP was done for 18 patients. All interventions were performed under general anesthesia. The follow-up protocol included body mass index (BMI), percentage of excess weight loss (%EWL), percentage of excess BMI loss (%EBMIL), and clinical assessment using the Gastro-esophageal Reflux Health-Related Quality-of-Life (GERD-HRQOL) scale at 6 and 12 months.

Results

The period of follow-up ranged from 12 to 33 months with a mean of 17.74 ± 3.73 months. The operation time was 1.40 ± 0.27 h. No serious procedure-related complications occurred. GERD-related symptoms resolved in all patients (p < 0.001). There was a significant improvment in endoscopic findings at 6 months compared to properatively (p = 0.001). There was a significant patient satisfaction score using GERD-HRQOL at 6 and 12 months (p = 0.000). The 1-year follow-up excess weight was significantly less than the baseline excess weight (p < 0.001). The average BMI decreased from 37.59 ± 1.89 kg/m² at baseline to 30.61 ± 1.57 kg/m² at 1 year (p < 0.001).

Conclusions

LNF combined with MGP for treatment of obese patients with GERD is technically safe, feasible, and promising with no serious procedure-related complications. The technique is effective in terms of weight loss and cure of GERD. However, future larger studies are required to demonstrate the safety, effectiveness, and long-term durability of the procedure.
