Visual Abstract, Highlights • The impact of breastfeeding on prolactin, cellular immune activation, and myocardial recovery was analyzed in 100 women with peripartum cardiomyopathy • Cardiac function was assessed by echocardiography at presentation and at serial intervals over the first year postpartum • The levels of circulating prolactin were assessed by ELISA, and cellular immunophenotyping by flow cytometry, and compared between breastfeeding and nonbreastfeeding women • Prolactin levels were higher in breastfeeding women and correlated with significant increases in CD8+ T cells • Despite significantly higher prolactin levels and increased CD8+ cells, myocardial recovery was similar in breastfeeding and nonbreastfeeding women, Summary The etiology of peripartum cardiomyopathy remains unknown. One hypothesis is that an increase in the 16-kDa form of prolactin is pathogenic and suggests that breastfeeding may worsen peripartum cardiomyopathy by increasing prolactin, while bromocriptine, which blocks prolactin release, may be therapeutic. An autoimmune etiology has also been proposed. The authors investigated the impact of breastfeeding on cellular immunity and myocardial recovery for women with peripartum cardiomyopathy in the IPAC (Investigations in Pregnancy Associated Cardiomyopathy) study. Women who breastfed had elevated prolactin, and prolactin levels correlated with elevations in CD8+ T cells. However, despite elevated prolactin and cytotoxic T cell subsets, myocardial recovery was not impaired in breastfeeding women.

OBJECTIVE: The aim of this work was to evaluate the hypothesis that the distribution of circulating immune cell subsets, or their activation state, is significantly different between peripartum cardiomyopathy (PPCM) and healthy postpartum (HP) women. BACKGROUND: PPCM is a major cause of maternal morbidity and mortality, and an immune-mediated etiology has been hypothesized. Cellular immunity, altered in pregnancy and the peripartum period, has been proposed to play a role in PPCM pathogenesis. METHODS: The Investigation of Pregnancy-Associated Cardiomyopathy (IPAC) study enrolled 100 women presenting with a left ventricular ejection fraction of

Previous research has indicated a relationship between posttraumatic stress disorder (PTSD) and somatic complaints. We examined whether this relationship is a result of shared comorbidity with anxiety and depression. Local doctors interviewed a random, community sample of 526 tortured and 526 nontortured Bhutanese refugees living in U.N. refugee camps in Nepal. The interview covered demographics, torture, somatic complaints, and PTSD, depression, and anxiety measures. Number of PTSD symptoms, independent of depression and anxiety, predicted both number of reported somatic complaints and number of organ systems involving such complaints. Physicians need to screen for PTSD when survivors of extreme stressors present nonspecific somatic complaints.

OBJECTIVE: To assess the quality of health information on material safety data sheets (MSDS) for a workplace chemical that is well known to cause or exacerbate asthma (toluene diisocyanate, TDI). DESIGN: We reviewed a random sample of 61 MSDSs for TDI products produced by 30 manufacturers. MEASUREMENTS AND MAIN RESULTS: Two physicians independently abstracted data from each MSDS onto a standardized audit form. One manufacturer provided no language about any respiratory effects of TDI exposure. Asthma was listed as a potential health effect by only 15 of the 30 manufacturers (50%). Listing asthma in the MSDS was associated with higher toluene diisocyanate concentrations in the product (P

Background: Pharmacological intervention with statin therapy in patients with coronary heart disease (CHD) is associated with long-term reduction of morbidity and mortality. Current Adult Treatment Panel III (ATP III) guidelines recommend an optimal goal of low-density lipoprotein cholesterol (LDL-C) < 100mg/dL in patients with CHD. The most recent percutaneous coronary intervention (PCI) guidelines recommend that it is reasonable to target a LDL-C Methods: A retrospective chart review of 415 patients who underwent PCI for CHD in a tertiary care academic medical center located in the Southeast. Data was gathered for patients with PCI from November 2008 to October 2009 and was used to evaluate lipid levels from one to twelve months post-PCI. Of the 415 total, 171 patients (mean age: 62 years, 43% (74 of 171) females, 38% (65 of 171) African Americans) met the inclusion criteria (regular follow up at our institution for at least twelve months after PCI) and were included for statistical analysis. Results: Statin therapy was initiated in 91% (156 of 171) of patients who underwent PCI for CHD before hospital discharge. LDL-C level below the desired goals of 70 mg/dL and 100 mg/dL were achieved in 17% (29 of 171) and 36% (61 of 171) of patients, respectively, one month after PCI. Improvement was noted over the following months with 26% (45 of 171), 30% (51 of 171), and 32% (55 of 171) of patients meeting goal LDL-C levels below 70 mg/dL by 6 months, 9 months, and 12 months, respectively. Furthermore, 51% (87 of 171), 43% (74 of 171), and 64% (109 of 171) of patients met a LDL-C goal less than 100mg/dL by 6, 9, and 12 months, respectively. These results did not differ by age, sex, or race when analyzed by chi-square test (p-values > 0.05). Conclusion: Our findings indicate that despite 91% of patients being discharged on statin therapy, only 32% of patients achieved goal LDL-C of 70mg/dL or below and 64% of patients below LDL-C of 100mg/dL at twelve months follow up after PCI. The results highlight a real life example of suboptimal LDL-C management in this high risk population. These findings emphasize the need to determine the factors responsible for this suboptimal management and to develop a mechanism for optimizing therapy with statins after PCI to prevent major cardiac adverse events.

Persistent hypotension subsequent to percutaneous coronary intervention is attributed to access-site bleeding, re-infarction, or mechanical complications either of myocardial infarction or of the procedure itself (for example, pericardial tamponade). Dynamic left ventricular outflow tract obstruction after an uncomplicated percutaneous coronary intervention is an unusual, and to our knowledge not previously reported, complication that manifests itself as hypotension refractory to the usual therapy with inotropic agents. We discuss the clinical course, pathophysiology, diagnosis, and management of hypotension due to left ventricular outflow tract obstruction after percutaneous coronary intervention. Early recognition and accurate diagnosis that determines appropriate therapy will improve the patient's prospects.

The objective was to study the external causes of death reported in the autopsy centre in Kathmandu, Nepal. A retrospective review of case report documentation of all violent and traumatic death autopsies was conducted in Kathmandu from mid-July 2000 to mid-July 2004. A total of 4383 autopsies were conducted by the Department of Forensic Medicine in Kathmandu. There were 1072 (25%) cases of suicide, 380 (9%) homicide, 1399 (32%) accidental, 598 (14%) deaths as a result of natural diseases and 923 (21%) undetermined causes of death. The number of males was almost twice that of females (sex ratio 2.2:1). Persons aged 15 to 44 years comprised about two-thirds of the total reported fatalities (65.4%). Suicides were mostly reported due to hanging, homicides mostly due to firearms and explosives, accidents mostly due to road traffic injuries. More than 60% of road traffic injuries resulted among pedestrians. Suicides, homicides and accidental deaths remain a poorly identified public health issue in Nepal. Medico-legal autopsy reports can serve as an important tool in understanding fatalities from violence and injuries for countries similar to Nepal. Strengthening a regular mechanism for compilation and utilization of the information, however, remains a major challenge.

Patients with chronic obstructive pulmonary disease (COPD) are at a mechanical disadvantage and should be predisposed to the development of diaphragmatic fatigue when the ventilatory system is stressed by exercise. The purpose of this study was to determine whether patients with moderately severe COPD develop contractile fatigue of the diaphragm after cycle exercise to the limits of tolerance. Twelve male patients with COPD, age 61.4 +/- 3.0 yr, participated. Their forced expiratory volume in 1 s (FEV(1)) was 1.79 +/- 0.14 L, 49.6 +/- 3.4% of predicted. Patients cycled at 60-70% of their predetermined maximal work capacity until they had to stop because of intolerable symptoms. Twitch transdiaphragmatic pressure (Pdi,tw) was measured during cervical magnetic stimulation before and 10, 30, and 60 min after exercise. A persistent fall in Pdi,tw postexercise of >/= 10% was considered potentially indicative of contractile fatigue of the diaphragm. Patients cycled for 10.2 +/- 2.0 min at a workload of 59.9 +/- 4.3 W. Patients exercised maximally relative to their capacity reaching a peak oxygen consumption (V O(2)) of 108.1 +/- 2.8% of the peak V O(2) obtained during a preliminary maximal incremental exercise test. Pdi,tw was not significantly different from baseline at any time postexercise. Pdi,tw was 19.9 +/- 1.6 cm H(2)O at baseline, 19.6 +/- 2.0 cm H(2)O at 10 min postexercise, 18. 6 +/- 2.0 cm H(2)O at 30 min postexercise, and 19.5 +/- 1.7 cm H(2)O at 60 min postexercise. In the individual patients, two of the patients had a persistent >/= 10% fall in Pdi,tw postexercise, potentially indicative of contractile fatigue of the diaphragm. In conclusion, the majority of patients with moderately severe COPD do not develop contractile fatigue of the diaphragm after high-intensity constant workload cycle exercise to the limits of tolerance.
