Surveillance for Colonization, Transmission, and Infection With Methicillin-Susceptible Staphylococcus aureus in a Neonatal Intensive Care Unit.

Importance: Staphylococcus aureus is one of the leading causes of infections in neonatal intensive care units (NICUs). Most studies in this patient group focus on methicillin-resistant S aureus or the outbreak setting, whereas data for methicillin-susceptible S aureus are limited. Objectives: To identify risk factors for S aureus colonization and infections in hospitalized newborns and to investigate S aureus transmission and its dynamics in a nonoutbreak setting. Design, Setting, and Participants: This monocentric cohort study in a tertiary NICU in Heidelberg, Germany, enrolled all hospitalized neonates (n = 590) with at least 1 nasal screening swab positive for S aureus. Data were collected from January 1, 2018, to December 31, 2019. Exposures: Weekly screening for S aureus colonization was performed for all newborns until discharge. Main Outcomes and Measures: The primary end point was any S aureus infection until hospital discharge. Transmission of S aureus and performance of routine typing to detect transmissions were defined as the secondary outcomes of the study. Results: In total, 590 newborns were enrolled (276 [46.8%] female and 314 [53.2%] male; 220 [37.3%] with birthweight <1500 g; 477 [80.8%] preterm; 449 [76.1%] singletons; 419 [71.5%] delivered via cesarean section). The median length of stay was 26 (range, 10-62) days. Overall, 135 infants (22.9%) were colonized by S aureus at some time during their hospital stay. The median time to first detection was 17 (interquartile range, 11-37) days. The overall incidence of S aureus infection was 1.7% (10 of 590). Low birth weight (<1500 g [odds ratio, 9.3; 95% CI, 5.9-14.6; P < .001]) and longer hospital stay (odds ratio, 2.3; 95% CI, 1.9-2.7; P < .001) were associated with colonization. Nasal carriage was significantly associated with S aureus infection (odds ratio, 8.2; 95% CI, 2.1-32.3; P = .002). A total of 123 of 135 colonization isolates were sequenced. All recoverable infection isolates (4 of 7) of newborns with colonization were genetically identical to the colonizing isolate. Whole-genome sequencing indicated 23 potential transmission clusters. Conclusions and Relevance: The findings of this cohort study suggest that nasal colonization is a relevant risk factor for S aureus infection in a nonoutbreak NICU setting. In colonized newborns, infection and colonization isolates were genetically identical, suggesting that eradication of colonization may be a useful measure to prevent infection. Further investigations are necessary to validate and assess the generalizability of our findings.

Exam preparation course in obstetrics and gynecology for the German Medical State Examination: proof of concept and implications for the recruitment of future residents.

OBJECTIVES: Today´s written part of the medical state examination requires students to retrieve a comprehensive amount of knowledge in a limited period of time. Therefore, the main study objectives were to implement and to evaluate a two-day exam preparation course for the German Medical State Examination in obstetrics and gynecology. The project evaluation focused on acceptability, satisfaction and the gain of knowledge for the participants of such a face-to-face course. STUDY DESIGN: The two-day intensive training for senior medical students offered a review of the entire exam-relevant content in the field of obstetrics and gynecology in combination with interactive discussions along selected exam questions. Skill gains were assessed using pre- and post-course multiple choice tests. In addition, a qualitative questionnaire assessed attitudes and satisfaction of course participants. RESULTS: A total of 101 fifth year senior medical students from Heidelberg University Medical School participated in the two pilot courses (summer 2014 and winter 2015). Pre- and post-course tests showed a significant skill-gain from 14.9 to 18.0 points [of a maximum of 20; pre-post difference 95 % CI (2.21; 3.98), t test: p < 0.001]. Furthermore, the qualitative results showed high satisfaction with the course, with an average Likert scale grading of 5.63 (2014) and 5.44 (2015) on a scale from 1 ("extraordinary bad") to 6 ("extraordinary good"). CONCLUSIONS: This study shows that a two-day intensive course in obstetrics and gynecology is feasible, effective and highly appreciated by senior medical students preparing for the Second German Medical State Examination. It further suggests surplus value for academic clinical departments to recruit future residents. Methods and tools presented in this paper are intended to inspire and guide clinical colleagues in implementing the format at their respective universities.

Change of Patient-Reported Aesthetic Outcome Over Time and Identification of Factors Characterizing Poor Aesthetic Outcome After Breast-Conserving Therapy: Long-Term Results of a Prospective Cohort Study.

BACKGROUND: We analyzed the change of aesthetic outcome (AO) over time and explored factors characterizing poor AO after breast-conserving surgery (BCS). METHODS: This prospective single-center cohort study included 849 patients preoperatively planned for BCS between September 2007 and December 2011. Long-term follow-up was made once in 2013. AO was measured by the Aesthetic Status (AS) of the Breast Cancer Treatment Outcome Scale questionnaire. Clinical, surgical, and pathologic variables were evaluated to identify predictors of poor AO. We applied single factor variance analyses and univariable logistic regression analyses for outcome analysis. RESULTS: The long-term follow-up rate in 2013 was 73 % (621 nonrecurrent with final BCS). A poor or fair AO was reported in 30 (4.8 %) and 98 (15.8 %) of these 621 patients, respectively. Single factor variance analysis showed a negative impact of higher specimen weight on AO (p < 0.001). Univariable logistic regression analysis revealed the following risk factors for poor AO: radial breast incision [odds ratio (OR) 1.97], periareolar incision (OR 1.85), fishmouth-shaped incision with resection of the nipple-areola complex (OR 8.12), impaired wound healing (OR 3.14), and seroma (OR 2.16). No patient rating her AO as fair or poor shortly after BCS improved in the long-term follow-up. CONCLUSIONS: The incidence of poor AO is relatively rare but increases in the long-term follow-up. Patients experiencing poor AO after BCS are likely to remain unsatisfied with the outcome over time. Factors predicting unfavorable AO can assist preoperative planning with regards to the choice between simple breast conserving techniques or more complex oncoplastic procedures.

Long-term objective esthetic outcome after breast-conserving therapy.

The prediction of unfavorable long-term esthetic outcome (AO) is important for patient consultation. We aimed to analyze variables characterizing the improvement and impairment of AO over time after breast-conserving surgery. A subgroup of a prospective, monocenter cohort study was analyzed to evaluate the results of the BCCT.core software (Breast Cancer Conservative Treatment.cosmetic results) which was used to objectively assess the AO before (n = 356), shortly after (n = 294) and in median 3 years after surgery (n = 356). We analyzed potential influencing factors (such as body mass index, (y)pT-stage, weight of resected specimen, etc.) on the AO using logistic regression analyses (n = 256). Finally, we tried to characterize groups of patients with improving or impaired AO over time (n = 294). Predictors for an unfavorable AO were an axillary lymphadenectomy (OR = 4.05), a tumor in the 12 o'clock position (OR = 2.22), a tumor stage larger or equal to (y)pT2 stage (OR = 2.11), and a surgical specimen weight >75 g (OR = 2.71). Patients with lower specimen weight were more likely to improve in the long-term follow-up (p = 0.018), whereas patients with a higher (y)pT-stage tended to become impaired with time. Although overall AO decreased over time, nearly half of the patients with an unfavorable AO shortly after surgery improved in the long-term follow-up. Predictors of unfavorable AO can be used in patient consultation preoperatively to prepare them for the postsurgical period and/or to recommend surgical alternatives (e.g., more complex oncoplastic techniques). Knowledge of improvement and impairment may help patients and physicians in the postsurgical consultation setting.

Diarrhoea prevalence in children under five years of age in rural Burundi: an assessment of social and behavioural factors at the household level.

BACKGROUND: Diarrhoea is the second leading cause of child mortality worldwide. Low- and middle-income countries are particularly burdened with this both preventable and treatable condition. Targeted interventions include the provision of safe water, the use of sanitation facilities and hygiene education, but are implemented with varying local success. OBJECTIVE: To determine the prevalence of and factors associated with diarrhoea in children under five years of age in rural Burundi. DESIGN: A cross-sectional survey was conducted among 551 rural households in northwestern Burundi. Areas of inquiry included 1) socio-demographic information, 2) diarrhoea period prevalence and treatment, 3) behaviour and knowledge, 4) socio-economic indicators, 5) access to water and water chain as well as 6) sanitation and personal/children's hygiene. RESULTS: A total of 903 children were enrolled. The overall diarrhoea prevalence was 32.6%. Forty-six per cent (n=255) of households collected drinking water from improved water sources and only 3% (n=17) had access to improved sanitation. We found a lower prevalence of diarrhoea in children whose primary caretakers received hygiene education (17.9%), boiled water prior to its utilisation (19.4%) and were aged 40 or older (17.9%). Diarrhoea was associated with factors such as the mother's age being less than 25 and the conviction that diarrhoea could not be prevented. No gender differences were detected regarding diarrhoea prevalence or the caretaker's decision to treat. CONCLUSIONS: Diarrhoea prevalence can be reduced through hygiene education and point-of use household water treatment such as boiling. In order to maximise the impact on children's health in the given rural setting, future interventions must assure systematic and regular hygiene education at the household and community level.

Public and private maternal health service capacity and patient flows in Southern Tanzania: using a geographic information system to link hospital and national census data.

BACKGROUND: Strategies to improve maternal health in low-income countries are increasingly embracing partnership approaches between public and private stakeholders in health. In Tanzania, such partnerships are a declared policy goal. However, implementation remains challenging as unfamiliarity between partners and insufficient recognition of private health providers prevail. This hinders cooperation and reflects the need to improve the evidence base of private sector contribution. OBJECTIVE: To map and analyse the capacities of public and private hospitals to provide maternal health care in southern Tanzania and the population reached with these services. DESIGN: A hospital questionnaire was applied in all 16 hospitals (public n=10; private faith-based n=6) in 12 districts of southern Tanzania. Areas of inquiry included selected maternal health service indicators (human resources, maternity/delivery beds), provider-fees for obstetric services and patient turnover (antenatal care, births). Spatial information was linked to the 2002 Population Census dataset and a geographic information system to map patient flows and socio-geographic characteristics of service recipients. RESULTS: The contribution of faith-based organizations (FBOs) to hospital maternal health services is substantial. FBO hospitals are primarily located in rural areas and their patient composition places a higher emphasis on rural populations. Also, maternal health service capacity was more favourable in FBO hospitals. We approximated that 19.9% of deliveries in the study area were performed in hospitals and that the proportion of c-sections was 2.7%. Mapping of patient flows demonstrated that women often travelled far to seek hospital care and where catchment areas of public and FBO hospitals overlap. CONCLUSIONS: We conclude that the important contribution of FBOs to maternal health services and capacity as well as their emphasis on serving rural populations makes them promising partners in health programming. Inclusive partnerships could increase integration of FBOs into the public health care system and improve coordination and use of scarce resources.

Vitamin D status among preterm and full-term infants at birth.

BACKGROUND: Risk factors for maternal vitamin D deficiency and preterm birth overlap, but the distribution of 25-hydroxyvitamin D (25(OH)D) levels among preterm infants is not known. We aimed to determine the associations between 25(OH)D levels and gestational age. METHODS: We measured umbilical cord plasma levels of 25(OH)D from 471 infants born at Brigham and Women's Hospital in Boston. We used generalized estimating equations to determine whether preterm (<37 wks' gestation) or very preterm (<32 wks' gestation) infants had greater odds of having 25(OH)D levels below 20 ng/ml than more mature infants. We adjusted for potential confounding by season of birth, maternal age, race, marital status, and singleton or multiple gestation. RESULTS: Mean cord plasma 25(OH)D level was 34.0 ng/ml (range: 4.1-95.3 and SD: 14.1). Infants born before 32 wks' gestation had increased odds of having 25(OH)D levels below 20 ng/ml in unadjusted (odds ratio (OR): 2.2; 95% confidence interval (CI): 1.1-4.3) and adjusted models (OR: 2.4; 95% CI: 1.2-5.3) as compared with more mature infants. CONCLUSION: Infants born in <32 wks' gestation are at higher risk than more mature infants for low 25(OH)D levels. Further investigation of the relationships between low 25(OH)D levels and preterm birth and its sequelae is thus warranted.

The internal migration between public and faith-based health providers: a cross-sectional, retrospective and multicentre study from southern Tanzania.

OBJECTIVE: To assess the magnitude, direction and underlying dynamics of internal health worker migration between public and faith-based health providers from a hospital perspective. METHODS: Two complementary tools were implemented in 10 public and six faith-based hospitals in southern Tanzania. A hospital questionnaire assessed magnitude and direction of staff migration between January 2006 and June 2009. Interviews with 42 public and 20 faith-based maternity nurses evaluated differences in staff perspectives and motives for the observed migration patterns. RESULTS: The predominant direction of staff movement was from the faith-based to the public sector: 69.1% (n = 105/152) of hospital staff exits and 60.6% (n = 60/99) of hospital staff gains. Nurses were the largest group among the migrating health workforce. Faith-based hospitals lost 59.3% (n = 86/145) of nurses and 90.6% (n = 77/85) of registered nurses to the public sector, whereby public hospitals reported 13.5% (n = 59/436) of nurses and 24.4% (n = 41/168) of registered nurses being former faith-based employees. Interviews revealed significantly inferior staff perspectives among faith-based respondents than their public colleagues. Main differences were identified regarding career development and training, management support, employee engagement and workload. CONCLUSION: This study revealed considerable internal health worker migration from the faith-based to the public sector. Staff retention and motivation within faith-based hospitals are not restricted to financial considerations, and salary gaps can no longer uniquely explain this movement pattern. The consequences for the catchment area of faith-based hospitals are potentially severe and erode cooperation potential between the public and private health sector.
