Serum leptin levels and relationship with maternal weight gain at term among obese and non-obese pregnant women in Enugu, Nigeria: a comparative cross-sectional study.

OBJECTIVE: To determine and compare the mean maternal serum leptin levels, the prevalence of high serum leptin levels and mean gestational weight gain at term among obese and non-obese pregnant women in Enugu, Nigeria. METHODS: This cross-sectional comparative study enrolled obese and non-obese pregnant women. The serum leptin levels of the women were determined using an enzyme-linked immunosorbent assay kit. Anthropometric and sociodemographic data were obtained and compared. Mean weight gain during pregnancy was determined. RESULTS: A total of 170 pregnant women were included in the study. The mean ± SD serum leptin level (99.39 ± 50.2 ng/ml) and the prevalence of hyperleptinaemia (81 of 85 patients; 95.3%) among the obese pregnant women at term were significantly higher than those of the non-obese pregnant women (48.98 ± 30.35 ng/ml/65 of 85 patients; 76.5%). The mean percentage weight gain was significantly higher in the non-obese women compared with the obese women at term. The predictors of high maternal serum leptin level at term among the participants were the employment status and levels of education of the participants. CONCLUSION: Maternal serum leptin level, maternal weight gain and prevalence of hyperleptinaemia at term were significantly higher in the obese compared with the non-obese pregnant women.

Survey of the Relationship Between Online Committee of Friends Meetings, Burials, and Coping With Bereavement Among Nigerians in Ebonyi State.

Online committee of friends meeting is a new trend in Nigeria. There is a continuous online interaction that goes on among the group members. The qualitative research design was used to carry out the study. The unstructured interview method was used to get information from the study participants. It was found among other things that the bereaved read, digest and accept the online condolence messages which serve as a coping tool to the loss of the loved one. Online COF is also a veritable tool in soliciting for and raising funds from online to facilitate the burial of loved ones owing to rising cost of conducting burials in Nigeria. It was concluded that coping with death is achieved in online COF through formation of whatsapp group, condolence messaging, friends digestion of information and acceptance of the pieces of advice raised and as divine will which comes when it will.

Out-of-hospital cardiac arrest without return of spontaneous circulation in the field: Who are the survivors?

BACKGROUND: Return of spontaneous circulation (ROSC) in the field is a vital determinant contributing to survival from out-of-hospital cardiac arrest (OHCA). However, nearly one third of survivors at the Dallas-Fort Worth (DFW) Resuscitation Outcomes Consortium (ROC) site did not obtain ROSC in the field. METHODS: A retrospective, observational analysis was performed on all adult patients with non-traumatic OHCA treated on scene and transported to hospital, who did not gain ROSC in the field at DFW ROC site between 2006 through 2011.We described the demographics, pre-hospital characteristics and outcomes of all enrolled cases. Those patients without ROSC in the field, who did and did not meet Termination of Resuscitation (TOR) criteria in the field, were also compared. RESULTS: Among a total of 5099 treated and transported non-traumatic OHCA cases, 83.2% (4243) were included in this study as patients without ROSC gained in the field, of which 66.6% (2827) met TOR criteria but still were treated and transported; 1.9% (79) survived to hospital discharge. Further analysis showed that 39.2% (31) of survivors met TOR rule, accounting for 1.1% of those patients who should have been declared dead in the field. Shockable initial rhythms, EMS-witnessed arrest, bystander CPR and age were factors significant to predict survival from OHCA without ROSC in the field. Of concern, 1.7% (47) of patients who met TOR presented initially shockable rhythms but no shocks were delivered in the field. CONCLUSIONS: We suggest that all treated non-traumatic OHCA patients should be transported to hospital.

The risk of endoscopic mucosal resection in the setting of clopidogrel use.

Objective. Guidelines on antiplatelet medication use during endoscopy are based on limited evidence. We investigate the risk of bleeding and ischemic events in patients undergoing endoscopic mucosal resection (EMR) of esophageal lesions in the setting of scheduled cessation and prompt resumption of clopidogrel. Design. Single centre retrospective review. Patients. Patients undergoing EMR of esophageal lesions. Interventions. Use of clopidogrel before EMR and resumption after EMR. Patients cease antiplatelets and anticoagulants 7 days before EMR and resume clopidogrel 2 days after EMR in average risk patients. Main Outcomes. Gastrointestinal bleeding (GIB) and ischemic events (IE) within 30 days of EMR. Results. 798 patients underwent 1716 EMR. 776 EMR were performed on patients on at least 1 antiplatelet/anticoagulant (APAC). 17 EMR were performed following clopidogrel cessation. There were 14 GIB and 2 IE. GIB risk in the setting of recent clopidogrel alone (0%) was comparable to those not on APAC (1.1%) (P = 1.0). IE risk on clopidogrel (6.3%) was higher than those not on APAC (0.1%) (P = 0.03). Limitations. Retrospective study. Conclusions. Temporary cessation of clopidogrel before EMR and prompt resumption is not associated with an increased risk of gastrointestinal bleeding but may be associated with increased ischemic events.

The intersection of intimate partner violence and HIV in U.S. women: a review.

The purposes of this study were to (a) review original research in the United States on the intersection of HIV risk and intimate partner violence (IPV) in women, and (b) identify trends that promote nursing and public health prevention and intervention strategies. Twenty-three original, peer-reviewed articles in the medical literature from 2008 to April 2012 were reviewed. Articles were eligible for inclusion if they addressed both HIV and IPV in women. Studies identified relationships between intimate partner victimization and HIV risk behaviors. Other factors compounding the complex relationship between IPV and increased HIV risk in women included sexual decision-making, male behavior, and substance use. A promising trend was found in the publication of studies addressing interventions. Prospective studies are needed to determine causality and temporal associations. Nursing interventions should focus on identifying women at risk for IPV, assessing HIV exposure risks, and providing culturally sensitive interventions and preventive measures.

Meniscal and chondral injuries associated with pediatric anterior cruciate ligament tears: relationship of treatment time and patient-specific factors.

BACKGROUND: Anterior cruciate ligament (ACL) tears are commonly associated with meniscal and chondral injuries. Although lateral meniscal tears are commonly associated with acute ACL injuries, the chronically ACL-deficient knee is associated with an increased rate of medial meniscal injury. These associations have been described in the adult knee literature. PURPOSE: To evaluate the relationship of elapsed time from injury with the incidence of meniscal and chondral injuries noted at the time of surgical treatment for ACL tears in pediatric patients. The effect of age, gender, weight, and mechanism of injury was also evaluated. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: A retrospective chart review of pediatric patients undergoing primary arthroscopic ACL reconstruction between January 2005 and January 2011 was performed. The presence of meniscal tear, chondral injury, number of days from injury to treatment, age, weight, gender, and mechanism of injury were recorded. The data were analyzed for associations between elapsed time before surgery as well as patient-specific factors with rates of meniscal and chondral injuries. RESULTS: Three hundred seventy pediatric patients who underwent primary ACL reconstruction were included. Two hundred forty-one were treated ≤150 days (early) from injury, and 129 were treated >150 days (delayed) from injury. Ninety-one (37.8%) patients in the early treatment group and 69 (53.5%) patients in the delayed treatment group had medial meniscal tears (MMTs) (P = .014; odds ratio [OR], 1.8; 95% confidence interval [CI], 1.12-2.83). Lateral meniscal tear (LMT) rates were similar (56.0% and 57.4%) in each group. Age >15 years also influenced the presence of MMTs (P = .033; OR, 1.6; CI, 1.04-2.54). Increased patient weight was associated with an increased rate of MMTs and LMTs. Fifty-four of 170 (31.8%) patients weighing ≤65 kg and 106 of 200 (53%) weighing >65 kg had MMTs (P < .001; OR, 2.2; CI, 1.36-3.42). Eighty-two of 170 (48.2%) patients weighing ≤65 kg and 127 of 200 (63.5%) weighing >65 kg had LMTs (P < .018; OR, 1.7; CI, 1.10-2.68). The presence of chondral injury was significantly associated with the presence of meniscal tear in the same compartment of the knee. CONCLUSION: Pediatric patients treated >150 days after injury for ACL tears have a higher rate of MMT than those treated ≤150 days after injury. Increased age and weight are independently associated with a higher rate of MMT. Patients with ACL tears and an MMT or LMT are more likely to have a chondral injury in that particular compartment than those without meniscal tears.

Safety of prior endoscopic mucosal resection in patients receiving radiofrequency ablation of Barrett's esophagus.

BACKGROUND & AIMS: Radiofrequency ablation (RFA) is safe and effective treatment for flat dysplasia associated with Barrett's esophagus (BE). However, there are limited data on the safety of RFA in patients who had prior endoscopic mucosal resection (EMR), which might increase the risk of complications. We compared complications and histologic outcomes between patients who had EMR before RFA and those who received only RFA. METHODS: We performed a retrospective analysis of data collected from patients treated for BE, associated with dysplasia or intramucosal cancer, at the Mayo Clinic in Rochester, Minnesota, from 1998-2009. Patients were divided into groups that had RFA after EMR (group 1, n = 44) or only RFA (group 2, n = 46). We compared the incidence of complications (strictures, bleeding, and esophageal perforation) and histologic features (complete resolution of dysplasia and complete resolution of intestinal metaplasia [CR-IM]) between groups. Logistic regression analysis was performed to assess predictors of stricture formation. RESULTS: Stricture rates were 14% in group 1 and 9% in group 2 (odds ratio, 1.53; 95% confidence interval [CI], 0.26-9.74). The rates of CR-IM were 43% in group 1 and 74% in group 2 (odds ratio, 0.33; 95% CI, 0.14-0.78). The rates of complete resolution of dysplasia were 76% in group 1 and 71% in group 2 (odds ratio, 1.28; 95% CI, 0.39-4.17). The adjusted odds ratio for CR-IM in group 1 (adjusting for age, segment length, and grade of dysplasia) was 0.50 (95% CI, 0.15-1.66). CONCLUSIONS: Stricture rates among patients who receive only RFA are comparable to those of patients who had prior EMR. EMR appears safe to perform prior to RFA.

Endoscopic evaluation and advanced imaging of Barrett's esophagus.

Enhanced visualization techniques are available for Barrett's esophagus and have promise in the detection of dysplasia and cancer. Several of these techniques, such as narrow band imaging and chromoendoscopy, are being applied clinically. These techniques will allow the endoscopist to screen the surface of the Barrett's esophagus to detect areas of neoplasia. Once detected, it is hoped that either magnification techniques, such as confocal laser endomicroscopy, or spectroscopic techniques can be of value in allowing in vivo real-time diagnostic capabilities.

Does alcohol involvement increase the severity of intimate partner violence?

BACKGROUND: Most studies that have examined alcohol use immediately prior to intimate partner violence (IPV) have been limited to male-to-female partner violence (MFPV) and are subject to a number of methodological limitations. We add new information concerning the relationship between alcohol involvement and severity of IPV, MFPV, and female-to-male partner violence (FMPV). METHODS: We analyzed data from a 1995 U.S. national population-based survey of couples > or = 18 years old. We examined 436 couples who reported IPV and had information on alcohol involvement with IPV. We measured IPV using a revised Conflict Tactics Scale, Form R that asked respondents about 11 violent behaviors in the past year. Respondents were classified into mutually exclusive categories as having experienced mild only or mild + severe ("severe") IPV, MFPV or FMPV. Respondents were also asked if they or their partner were drinking at the time the violent behavior occurred and were classified as exposed to IPV with or without alcohol involvement. We estimated proportions, odds ratios, 95% confidence intervals, and p-values of the proposed associations, accounting for the complex survey design. RESULTS: Overall, 30.2% of couples who reported IPV reported alcohol involved IPV; 69.8% reported no alcohol involvement. In adjusted analyses, those reporting severe (vs. mild only) IPV were more than twice as likely to report alcohol involvement. In adjusted analyses, those reporting severe (vs. mild) MFPV or FMPV were more likely to report female but not male alcohol involvement. Though estimates were positive and strong, most confidence intervals were compatible with a wide range of estimates including no association. CONCLUSIONS: Our findings suggest alcohol involvement of either or both in the couple increases the risk of severe IPV. Our findings also suggest female alcohol use may play an important role in determining the severity of IPV, MFPV or FMPV.

Prohibitin inhibits tumor necrosis factor alpha-induced nuclear factor-kappa B nuclear translocation via the novel mechanism of decreasing importin alpha3 expression.

Expression of prohibitin 1 (PHB), a multifunctional protein in the cell, is decreased during inflammatory bowel disease (IBD). Little is known regarding the regulation and role of PHB during intestinal inflammation. We examined the effect of tumor necrosis factor alpha (TNF-alpha), a cytokine that plays a central role in the pathogenesis of IBD, on PHB expression and the effect of sustained PHB expression on TNF-alpha activation of nuclear factor-kappa B (NF-kappaB) and epithelial barrier dysfunction, two hallmarks of intestinal inflammation. We show that TNF-alpha decreased PHB protein and mRNA abundance in intestinal epithelial cells in vitro and in colon mucosa in vivo. Sustained expression of prohibitin in intestinal epithelial cells in vitro and in vivo (prohibitin transgenic mice, PHB TG) resulted in a marked decrease in TNF-alpha-induced nuclear translocation of the NF-kappaB protein p65, NF-kappaB/DNA binding, and NF-kappaB-mediated transcriptional activation despite robust IkappaB-alpha phosphorylation and degradation and increased cytosolic p65. Cells overexpressing PHB were protected from TNF-alpha-induced increased epithelial permeability. Expression of importin alpha3, a protein involved in p50/p65 nuclear import, was decreased in cells overexpressing PHB and in colon mucosa of PHB TG mice. Restoration of importin alpha3 levels sustained NF-kappaB activation by TNF-alpha during PHB transfection. These results suggest that PHB inhibits NF-kappaB nuclear translocation via a novel mechanism involving alteration of importin alpha3 levels. TNF-alpha decreases PHB expression in intestinal epithelial cells and restoration of PHB expression in these cells can protect against the deleterious effects of TNF-alpha and NF-kappaB on barrier function.

Gender-related issues in the female inflammatory bowel disease patient.

Inflammatory bowel diseases (IBDs) commonly affect women in their childbearing years. Women identify unique psychologic issues compared with men related to body image and their ability to bear children. The menstrual cycle can be disrupted because of disease activity, medications and/or malnutrition. Oral contraceptives can be used; however, monitoring for thromboembolic events should be performed. Women with IBD are potentially at risk of higher rates of cervical dysplasia and should be screened as are other immunocompromised women. Fertility rates are comparable to those of women without IBD. The risk of disease activity during pregnancy depends on the disease activity at the time of conception. Pregnancy for the majority of women is uncomplicated, although women with Crohn's disease do tend to deliver children of lower birthweights than do healthy women. The majority of medications used in the treatment of IBD are not harmful to the fetus and should be continued throughout pregnancy in order to maintain maternal health. Breastfeeding should not be discouraged and the majority of medications are safe for nursing. Menopause tends to occur earlier in women with IBD; the cause of this is unclear.

Ursodeoxycholic acid treatment for patients with postcholecystectomy pain and bile microlithiasis.

BACKGROUND: Microlithiasis has been identified as a cause of idiopathic acute pancreatitis in patients with an intact gallbladder. Microlithiasis has also been identified in the bile of some patients who have undergone cholecystectomy. However, it is unknown whether bile microlithiasis causes postcholecystectomy pain. OBJECTIVE: To identify bile microlithiasis in patients with postcholecystectomy pain and to investigate the therapeutic effect of ursodeoxycholic acid (urso) on such patients with microlithiasis in the bile. DESIGN: Prospective randomized trial. SETTING: Tertiary medical center. PATIENTS: Patients with postcholecystectomy pain and bile crystals. INTERVENTIONS: Urso treatment. MAIN OUTCOME MEASUREMENTS: The severity and frequency of right upper-quadrant abdominal pain were compared with and without urso treatment, and before and after urso treatment. RESULTS: A total of 118 patients with postcholecystectomy pain were screened for the study. Twelve patients (10%) were identified with bile crystals. In the first phase, 6 of these patients received urso treatment, whereas the other 6 patients did not receive urso treatment. In the second phase, the latter 6 patients were given the urso treatment. After using urso for a few months, their biliary-type abdominal pain significantly improved or resolved. In the control group, there was no improvement in symptoms. There was a significant difference between the 2 groups (P = .01). LIMITATIONS: Single-center, small number of patients. CONCLUSIONS: This study provided evidence that supports the hypothesis that bile microlithiasis is indeed a cause for postcholecystectomy pain. Patients with such postcholecystectomy pain may benefit from a microscopic examination of bile for crystals or microlithiasis, and urso treatment if bile crystals are identified.

Complex molecular epidemiology of methicillin-resistant staphylococcus aureus isolates from children with cystic fibrosis in the era of epidemic community-associated methicillin-resistant S aureus.

BACKGROUND: Limited data exist about the molecular types of methicillin-resistant Staphylococcus aureus (MRSA) strains found in children with cystic fibrosis (CF). We sought to characterize MRSA strains from these patients and compare them with MRSA strains from non-CF pediatric patients. METHODS: All MRSA isolates were collected prospectively at Children's Medical Center in Dallas, TX, and the University of Chicago Comer Children's Hospital in 2004 to 2005. All CF MRSA isolates underwent susceptibility testing, multilocus sequence typing, Panton-Valentine leukocidin gene detection (pvl+), and staphylococcal chromosome cassette mec (SCCmec) typing. RESULTS: A total of 22 of 34 MRSA isolates (64.7%) from patients with CF belonged to clonal complex (CC) 5 and contained SCCmec II, so-called health-care associated MRSA (HA-MRSA) strains. Nine of 34 MRSA strains (26.5%) were CC 8, and contained SCCmec IV, so-called community-associated MRSA (CA-MRSA) strains. The CA-MRSA strains tended to be isolated from newly colonized CF patients. In contrast, CC8 isolates predominated among the non-CF patients (294 of 331 patients; 88.8%). MRSA isolates from children with CF were more likely to be resistant to clindamycin (65% vs 19%, respectively) and ciprofloxacin (62% vs 17%, respectively) compared with strains from non-CF patients (p < 0.001). There was no difference in the rate of pvl+ isolate recovery from children with CF undergoing a surveillance culture (7 of 23 children) compared with those with pulmonary exacerbation (3 of 11 children; p = 1.0). CONCLUSIONS: Both CA-MRSA (CC8) isolates and HA-MRSA (CC5) isolates populate the respiratory tracts of children with CF. HA-MRSA isolates predominated, but CA-MRSA strains predominated among CF patients with newly acquired MRSA strains and among the non-CF patients. The presence of CA-MRSA strains in children with CF was not associated with exacerbation or necrotizing pneumonia.
