BACKGROUND

Knowledge of nasal carriage is important in predicting staphylococcal infection, and no information exists regarding the endemicity of Staphylococcus aureus in Haiti.

METHODS

We performed a cross-sectional analysis of S. aureus nasal screening in an acute care, a subacute rehabilitation, and a community setting, with a brief medical and epidemiological history. PCR-positive S. aureus screening nasal cultures underwent molecular analysis for spa type, SCCmec type, and virulence genes (Panton-Valentine leukocidin (PVL), toxic shock syndrome toxin (TSST), and arginine catabolic mobile element (ACME)), and were evaluated for antibiotic susceptibility using commercial tests.

RESULTS

Overall carriage rates of 8.4% methicillin-susceptible S. aureus (MSSA) and 2.8% methicillin-resistant S. aureus (MRSA) were identified, with a high rate of tetracycline resistance. TSST and PVL genes were identified in MSSA. MRSA isolates contained no virulence markers. Unique MSSA phenotypes (i.e., linezolid-resistant, vancomycin-sensitive/daptomycin non-susceptible) were identified, as were two PVL-positive ST152 MSSA colonization isolates, previously geographically limited to Africa.

CONCLUSIONS

We found a low S. aureus carriage rate with complete vancomycin susceptibility and high tetracycline resistance, which has important public health implications with regard to treatment. Additionally, the finding of PVL-positive MSSA isolates, including the expansion of a previously described limited 'divergent' clone, ST152, warrants further evaluation.

Children whose mothers are victims of intimate partner violence (IPV) are at increased risk of adverse health and psychosocial consequences, including becoming victims or perpetrators of violence in their own relationships. This study aimed to understand the role mothers may play in preventing the perpetuation of violence in their children's lives. We performed semistructured interviews with 18 IPV victims who are mothers and were living at the Women's Center & Shelter of Greater Pittsburgh from July through November 2011. We sought to understand how they communicate with their children about IPV and relationships. These mothers described a desire to explain their IPV experience and offer advice about avoiding violence in relationships. As foundations for these discussions, they emphasized the importance of close relationships and open communication with their children. Although mothers are interested in talking about IPV and relationships and identify communication strategies for doing so, many have never discussed these topics with their children. These mothers need and want an intervention to help them learn how to communicate with their children to promote healthy relationships. Development of a program to facilitate communication between IPV victims and their children could create an important tool to empower mothers to break the cross-generational cycle of domestic violence.

CONTEXT

The burden of injuries to college ultimate players has never been fully described.

OBJECTIVE

To quantify the injury rate in ultimate players and describe the diagnoses, anatomic locations, and mechanisms of injuries.

DESIGN

Descriptive epidemiology study.

SETTING

College ultimate teams in the United States during the 2012 season.

MAIN OUTCOME MEASURE(S)

Initial injury rate per 1000 athlete-exposures.

RESULTS

The initial injury rate in college ultimate players was 12.64 per 1000 athlete-exposures; the rate did not differ between men and women (P = .5). Bivariate analysis indicated that injuries occurred twice as often during games as during practices, men were more likely than women to be injured when laying out for the disc, and men were more likely to incur strains and sprains than women.

CONCLUSIONS

Injury patterns to college ultimate players were similar to those for athletes in other National Collegiate Athletic Association sports. This is the first study to systematically describe injuries to ultimate players.

PURPOSE

Previous studies analyzing the relationship between Body Mass Index (BMI) and complications after partial nephrectomy have been underpowered. We use a national surgical database to explore the association of BMI with postoperative outcomes for Open Partial Nephrectomy (OPN) and Minimally Invasive Partial Nephrectomy (MIPN).

PATIENTS AND METHODS

Years 2005-2012 of the National Surgical Quality Improvement Program (NSQIP) were queried for OPN and MIPN. Postoperative complications were organized according to Clavien Grades and compared across normal weight (BMI kg/m(2)=18.5-<25.0), overweight (BMI=25.0-<30.0), and obese (BMI≥30.0) patients using standard descriptive statistics and multivariate regression modeling.

RESULTS

Of 1667 OPNs and 2018 MIPNs, 46.2% of patients were obese. Operative time was 16.91 minutes longer on average for obese patients (p<0.001). The overall complication rate after OPN was 17.9%, 17.2%, and 17.9% (p=0.945) for normal weight, overweight, and obese patients, respectively; while the overall complication rate after MIPN was 6.9%, 6.3%, and 8.7% (p=0.147). Multivariate regression analysis demonstrated that overweight and obese patients were not at increased risk for any complication grade after OPN and MIPN compared to normal weight patients. When comparing procedures, MIPN had a lower complication rate compared to OPN for obese (8.7% vs 17.9%, p<0.001) and morbidly obese patients (9.2% vs 22.2%, p=0.001).

CONCLUSIONS

Although surgery in obese patients is longer compared to normal weight patients, it does not appear to increase the likelihood of 30-day postoperative complications for OPN or MIPN. However, obese patients undergoing MIPN had lower complication rates than those undergoing OPN.

PURPOSE

The Patient Protection and Affordable Care Act increases oversight of surgical outcomes and ties hospital readmissions to Medicare reimbursement. Given the increasing volume of outpatient urological procedures, to our knowledge this study provides the first multi-institutional multivariate analysis of patient factors that contribute to readmission.

MATERIALS AND METHODS

Using the 2011 National Surgical Quality Improvement Program database we identified 7,795 patients. Multiple logistic regression was used to predict 30-day unplanned hospital readmissions controlling for demographics, clinical characteristics and comorbidities. Readmission rates of the 5 most common procedures were calculated along with the rate of postoperative complications associated with readmission.

RESULTS

Outpatient urological surgery had an overall 3.7% readmission rate. The 5 most common procedures were cystourethroscopy and resection of bladder tumor (readmission rate 4.97%), laser prostatectomy (4.27%), transurethral resection of prostate (4.24%), hydrocele excision (1.92%) and sling surgery for urinary incontinence (0.85%). The most common comorbidities in readmitted patients were hypertension, diabetes and smoking. Risk adjusted multiple regression indicated that cancer history (OR 3.48), bleeding disorder (OR 2.03), male gender (OR 1.38), ASA(®) level 3 or 4 (OR 1.34) and age (OR 1.01) were significant predictors of readmission. Readmitted patients also had a higher 30-day complication rate.

CONCLUSIONS

Readmission after outpatient urological surgery occurs at a rate of 3.7%. A history of cancer, bleeding disorder, male gender, ASA level 3 or 4 and age were associated with readmission along with greater rates of medical and surgical complications. Our results may help guide risk reduction initiatives and prevent costly readmissions.

OBJECTIVE

Hypertension is an important risk factor for cardiovascular disease throughout the world. Little is known about the prevalence of hypertension in rural Haiti. Our study aims to estimate prevalence and knowledge of hypertension in Northern Haiti.

DESIGN

Cross-sectional.

SETTING

Four rural communities surrounding Milot, Haiti.

PARTICIPANTS

Participants (69 males, 106 females, 175 total) were eligible to take part if they were aged > 18 years and not pregnant. Enrollment was voluntary.

METHODS

Two initial blood pressure measurements were taken for each participant. Participants who had an average systolic blood pressure > or = 140 mm Hg or diastolic blood pressure > or = 90 mm Hg were instructed to return in 1 week for two additional confirmatory measurements. Based on these measures, participants were classified as either hypertensive or not. All participants were surveyed to assess their knowledge of hypertension.

RESULTS

The prevalence of hypertension among the study sample was 36.6%. Overall, 47% of women and 21% of men were hypertensive. Approximately 30% of women of reproductive age (18-39 years) were hypertensive. Participants showed little knowledge of the asymptomatic nature of hypertension and the need for lifelong treatment.

CONCLUSIONS

Hypertension is prevalent in Haiti. The high prevalence of hypertension among women of reproductive age is a concern since it is a risk factor for cardiovascular disease. Lack of knowledge surrounding hypertension indicates low awareness of the condition and is a possible target for future educational interventions.

PURPOSE

We identified rates of and risk factors for complications after colpocleisis using the American College of Surgeons NSQIP® database.

MATERIALS AND METHODS

Women treated with Le Fort colpocleisis from 2005 to 2011 were identified in the database. Primary outcomes were 30-day complication rates. Secondary outcomes were risk factors for complications and the impact of age and a concomitant sling on morbidity. Clinical and procedural characteristics were compared using the chi-square test and 1-way ANOVA.

RESULTS

We identified 283 women, of whom 23 (8.1%) experienced complications. The most common complication was urinary tract infection in 18 women (6.4%). There was 1 death for a 0.4% mortality rate. Increased complications were associated with age less than 75 years (p = 0.03), chronic obstructive pulmonary disease (p = 0.03), hemiplegia (p = 0.03), disseminated cancer (p = 0.03) and open wound infection (p = 0.02). Six patients (2.1%) required return to the operating room within 30 days. Complication rates did not differ based on operative time (p = 0.78), inpatient status (p = 0.24), resident involvement (p = 0.35), concomitant sling placement (p = 0.81) or anesthesia type (p = 0.27). Women undergoing colpocleisis without (191) and with (92) a sling had similar baseline characteristics. Colpocleisis without and with a sling had similar rates of complications (7.9% vs 8.7%, p = 0.81), urinary tract infection (5.8% vs 7.6%, p = 0.55), return to the operating room (2.1% vs 2.2%, p = 0.97) and mortality (0% vs 1.1%, p = 0.15).

CONCLUSIONS

Mortality and complication rates after colpocleisis are low with urinary tract infection being the most common postoperative complication. Concomitant sling placement does not increase 30-day complication rates.

The World Health Organization recommends anthelminthic treatment for pregnant women after the first trimester in soil-transmitted helminth (STH) endemic regions to prevent adverse maternal-fetal consequences. Although studies have shown the high prevalence of infection in the Philippines, no research has evaluated deworming practices. We hypothesized that pregnant women are not receiving deworming treatment and we aimed to identify barriers to World Health Organization guideline implementation. We conducted key informant interviews with local Department of Health (DOH) administrators, focus group discussions with nurses, midwives, and health care workers, and knowledge, attitudes, and practices surveys with women of reproductive age to elicit perspectives about deworming during pregnancy. Key informant interviews revealed that healthcare workers were not deworming pregnant women due to inadequate drug supply, infrastructure and personnel as well as fear of teratogenicity. Focus group discussions showed that healthcare workers similarly had not implemented guidelines due to infrastructure challenges and concerns for fetal malformations. The majority of local women believed that STH treatment causes side effects (74.8%) as well as maternal harm (67.3%) and fetal harm (77.9%). Women who were willing to take anthelminthics while pregnant had significantly greater knowledge as demonstrated by higher Treatment Scores (mean rank 146.92 versus 103.1, z = -4.40, p<0.001) and higher Birth Defect Scores (mean rank 128.09 versus 108.65, z = -2.43, p = 0.015). This study concludes that World Health Organization guidelines are not being implemented in the Philippines. Infrastructure, specific protocols, and education for providers and patients regarding anthelminthic treatment are necessary for the successful prevention of STH morbidity and mortality among pregnant women.

BACKGROUND

Venous thromboembolism (VTE) is a significant cause of morbidity and mortality, particularly in the postoperative setting. Various risk stratification schema exist in the plastic surgery literature, but do not take into account variations in procedure length. The putative risk of VTE conferred by increased length of time under anaesthesia has never been rigorously explored.

AIM

The goal of this study is to assess this relationship and to benchmark VTE rates in plastic surgery.

METHODS

A large, multi-institutional quality-improvement database was queried for plastic and reconstructive surgery procedures performed under general anaesthesia between 2005-2011. In total, 19,276 cases were abstracted from the database. Z-scores were calculated based on procedure-specific mean surgical durations, to assess each case's length in comparison to the mean for that procedure. A total of 70 patients (0.36%) experienced a post-operative VTE. Patients with and without post-operative VTE were compared with respect to a variety of demographics, comorbidities, and intraoperative characteristics. Potential confounders for VTE were included in a regression model, along with the Z-scores.

RESULTS

VTE occurred in both cosmetic and reconstructive procedures. Longer surgery time, relative to procedural means, was associated with increased VTE rates. Further, regression analysis showed increase in Z-score to be an independent risk factor for post-operative VTE (Odds Ratio of 1.772 per unit, p-value < 0.001). Subgroup analyses corroborated these findings.

CONCLUSIONS

This study validates the long-held view that increased surgical duration confers risk of VTE, as well as benchmarks VTE rates in plastic surgery procedures. While this in itself does not suggest an intervention, surgical time under general anaesthesia would be a useful addition to existing risk models in plastic surgery.
