Novel passive detection approach reveals low breeding season survival and apparent lactation cost in a critically endangered cave bat.

Capture-mark-recapture/resight (CMR) methods are used for survival-rate studies, yet are often limited by small sample sizes. Advances in passive integrated transponder (PIT) technology have enabled passive detection or 'resight' of marked individuals using large antennas with greater read-ranges than previously possible. We used passively-detected resight data and CMR models to study survival rates of the southern bent-winged bat Miniopterus orianae bassanii, a critically endangered, cave-dwelling bat. Over three years, we used PIT-tagging to monitor 2966 individuals at the species' largest breeding aggregation, using daily detection data (> 1.6 million detections) to estimate seasonal survival probabilities, structured by age, sex and reproductive status, and parameterise population projection matrices. This has hitherto been impossible using traditional CMR methods due to disturbance risk and low recapture rates. Bats exhibited lowest apparent seasonal survival over summer and autumn, particularly for reproductive females in summer (when lactating) and juveniles in autumn (after weaning), and high survival in winter. Lowest survival rates coincided with severe drought in summer-autumn 2016, suggesting that dry conditions affect population viability. Under all likely demographic assumptions, population projection matrices suggested the population is in deterministic decline, requiring urgent action to reduce extinction risk. Passively-collected resight data can now be used in combination with CMR models to provide extensive, robust information for targeted wildlife population management.

Safety Aspects of a Randomized Clinical Trial of Maternal and Infant Vitamin D Supplementation by Feeding Type Through 7 Months Postpartum.

Background: The safety of higher dose vitamin D (vitD) supplementation in women who change from exclusive or full breastfeeding to combination feeding or who continue supplementation after cessation of breastfeeding is unknown. Objective: Compare vitD supplementation safety of 6,400 to 400 IU/day and 2,400 IU/day using specific laboratory parameters in postpartum women and their infants through 7 months postpartum by feeding type. Design: In this randomized controlled trial, mothers (exclusively breastfeeding or formula-feeding) were randomized at 4-6 weeks' postpartum to 400, 2,400, or 6,400 IU vitD3 (cholecalciferol)/day for 6 months. Breastfeeding infants in 400 IU group received oral 400 IU vitD3/day; infants in 2,400 and 6,400 IU groups received placebo. Maternal safety parameters (serum vitD, 25-hydroxy-vitamin D [25(OH)D; calcidiol], calcium, phosphorus, intact PTH; urinary calcium/creatinine ratios; and feeding type/changes) were measured monthly; infant parameters were measured at months 1, 4, and 7. Sufficiency was defined as 25(OH)D >50 nmol/L. Feeding type was defined as exclusive/full, combination, or formula-feeding. Data were analyzed using SAS 9.4. Results: Four hundred nineteen mother-infant pairs were randomized into the three treatment groups and followed: 346 breastfeeding and 73 formula-feeding pairs. A dose of 6400 IU/day safely and significantly increased maternal vitD and 25(OH)D from baseline in all mothers regardless of feeding type (p < 0.0001) and was superior to the 400 and 2,400 IU groups in achieving vitD sufficiency with no other differences in safety parameters by treatment or feeding type. Infants in the 2,400 IU group were more likely vitD-deficient than the other groups; otherwise, there were no infant safety parameter differences. Conclusions: While 6,400 IU/day was more effective than 400 or 2,400 IU/day in achieving maternal vitD sufficiency in all feeding groups, the groups did not differ on other safety parameters. Similarly, infant safety parameters did not differ by treatment group or feeding status. Clinical Trial Registration: FDA IND Number: 66,346; ClinicalTrials.gov Number: NCT00412074.

Prenatal Provider Support for Breastfeeding: Changes in Attitudes, Practices and Recommendations Over 22 Years.

BACKGROUND: Prenatal care providers play a central role in breastfeeding outcomes. A survey on obstetricians' support of breastfeeding was conducted in 1993 in Monroe County, NY. Since the landscape of prenatal care and breastfeeding support has changed significantly in the past 2 decades, we repeated and extended this survey in 2015. RESEARCH AIM: To determine changes in breastfeeding support by prenatal care providers over a 20 year period. METHODS: We sent a 46-item on-line or paper questionnaire to all categories of prenatal care providers identified by an online search. A breastfeeding support score was created based on the prior survey, with a maximum score of 3. One point was awarded for: (1) personally discussing breastfeeding; (2) generally suggesting breastfeeding; and (3) commonly receiving questions from patients. Data were analyzed using Chi-square. RESULTS: We had 164 participants (response rate 80%). More current participants, compared to 1993, reported discussing (97% vs. 86%, p < .001) and recommending (93% vs. 80%, p = .001) breastfeeding. Only 10% of 2015 participants gave infant formula samples, compared with 34% in 1993 (p < .0001). Improvement in the support score was seen, with 98% of current participants having high scores compared to 87% in 1993 (p < .001). Similar numbers reported receiving breastfeeding education, though more reported that the education was inadequate (54% vs. 19%, p < .0001). CONCLUSION: Breastfeeding support improved significantly over time, even though breastfeeding education has not improved in quality or quantity. Improving education of prenatal care providers may help future providers be more prepared to support breastfeeding.

High detectability with low impact: Optimizing large PIT tracking systems for cave-dwelling bats.

Passive integrated transponder (PIT) tag technology permits the "resighting" of animals tagged for ecological research without the need for physical re-trapping. Whilst this is effective if animals pass within centimeters of tag readers, short-distance detection capabilities have prevented the use of this technology with many species. To address this problem, we optimized a large (15 m long) flexible antenna system to provide a c. 8 m2 vertical detection plane for detecting animals in flight. We installed antennas at two roosting caves, including the primary maternity cave, of the critically endangered southern bent-winged bat (Miniopterus orianae bassanii) in south-eastern Australia. Testing of these systems indicated PIT-tags could be detected up to 105 cm either side of the antenna plane. Over the course of a three-year study, we subcutaneously PIT-tagged 2,966 bats and logged over 1.4 million unique detections, with 97% of tagged bats detected at least once. The probability of encountering a tagged bat decreased with increasing environmental "noise" (unwanted signal) perceived by the system. During the study, we mitigated initial high noise levels by earthing both systems, which contributed to an increase in daily detection probability (based on the proportion of individuals known to be alive that were detected each day) from <0.2 (noise level ≥30%) to 0.7-0.8 (noise level 5%-15%). Conditional on a low (5%) noise level, model-based estimates of daily encounter probability were highest (>0.8) during peak breeding season when both female and male southern bent-winged bats congregate at the maternity cave. In this paper, we detail the methods employed and make methodological recommendations for future wildlife research using large antennas, including earthing systems as standard protocol and quantifying noise metrics as a covariate influencing the probability of detection in subsequent analyses. Our results demonstrate that large PIT antennas can be used successfully to detect small volant species, extending the scope of PIT technology and enabling a much broader range of wildlife species to be studied using this approach.

Exploring the spectrum of late effects following radical orchidectomy for stage I testicular seminoma: a systematic review of the literature.

PURPOSE: Testicular seminomas occur in young men and are highly curable. Toxicities following treatment for men with extensive stage II-III seminomas may cause long-term morbidities. However, it is not clear whether the risk of late effects also increases following surgery for testis-confined seminoma. In this systematic review, we examined the available literature regarding the incidence of late effects in our target population of patients with stage I seminoma treated with orchidectomy alone. METHOD: Publications were identified through an electronic literature search using the MEDLINE, EMBASE and PsychInfo databases, identifying cohorts treated for stage I seminoma. Data on late effects were collected and classified as physical or psychological. RESULTS: Six hundred and four articles were screened to identify 100 studies. In the target population, available evidence suggests no increased risk of cardiovascular disease, metabolic syndrome, or renal dysfunction compared to the general population. Sperm counts were initially lower than an age-matched cohort; however, counts normalised when re-assessed 5 years later. Data were not specifically reported for the target population regarding bone health, second malignancy, hypogonadism, fertility and all psychological domains. Heterogeneity of study design and reporting methods contributed to uncertainty regarding the true incidence and clinical significance of late effects. CONCLUSIONS: The curability of stage I seminoma and the wide range of potential late effects of treatment suggest the need for long-term monitoring alongside standard cancer surveillance. Important data are needed on the prevalence of late effects, specifically related to testicular cancer survivors undergoing surveillance following orchidectomy. IMPLICATIONS FOR CANCER SURVIVORS: Awareness and screening for relevant late effects may prevent further morbidity in men treated for stage I seminoma.

Building New York State Centers of Excellence in Children's Environmental Health: A Replicable Model in a Time of Uncertainty.

Public health programs may be seriously affected in periods of federal retrenchment. During these times, state-based strategies provide an alternate pathway for advancing public health.A 12-year campaign to secure state support for a network of Centers of Excellence in Children's Environmental Health (CEH) promoting health of children across New York State is described. It was driven by rising rates of asthma, birth defects, developmental disorders, and other noncommunicable diseases in children; growing evidence associating hazardous environmental exposures with these conditions; and recognition that federal resources in CEH are insufficient.Critical campaign elements were (1) formation of a statewide coalition of academic health centers, health care providers, public health officials, community advocates, and other stakeholders; (2) bipartisan collaborations with legislative champions and government leaders; (3) assessment of the burden of developmental disorders and noncommunicable diseases associated with environmental exposures among children; (4) maps documenting the presence of environmental hazards in every county statewide; (5) iterative charting of a changing political landscape; and (6) persistence. The 2017 award of a 5-year, $10 million contract to establish Centers of Excellence in CEH demonstrates the value of this statewide strategy.

Treatment of Narcolepsy with Sodium Oxybate While Breastfeeding: A Case Report.

BACKGROUND: Sodium oxybate is used in the treatment of narcolepsy. Currently no published literature supports its safety during breastfeeding, although it has a favorable pharmacokinetic profile for minimizing exposure. MATERIALS AND METHODS: We report a case of a 27-year-old primigravida with narcolepsy who was taking sodium oxybate for symptom control and contacted our Lactation Study Center for advice. Based on our current pharmacokinetic knowledge, she was advised to avoid breastfeeding 4 hours after a dose. RESULTS: Follow-up phone interviews were done and the patient reported that the feeding schedule was manageable, and she was able to exclusively breastfeed for 6 months of her infant's life. Based on pediatric records, her infant's growth and development were excellent. There were no noted side effects of the medication for the infant. CONCLUSIONS: This is the first report to our knowledge of breastfeeding during maternal therapy with sodium oxybate, which appears to be compatible with safe, exclusive breastfeeding when managed appropriately.

Impact of Donor Milk Availability on Breast Milk Use and Necrotizing Enterocolitis Rates.

OBJECTIVES: To examine the availability of donor human milk (DHM) in a population-based cohort and assess whether the availability of DHM was associated with rates of breast milk feeding at NICU discharge and rates of necrotizing enterocolitis (NEC). METHODS: Individual patient clinical data for very low birth weight infants from the California Perinatal Quality Care Collaborative were linked to hospital-level data on DHM availability from the Mothers' Milk Bank of San José for 2007 to 2013. Trends of DHM availability were examined by level of NICU care. Hospitals that transitioned from not having DHM to having DHM availability during the study period were examined to assess changes in rates of breast milk feeding at NICU discharge and NEC. RESULTS: The availability of DHM increased from 27 to 55 hospitals during the study period. The availability increased for all levels of care including regional, community, and intermediate NICUs, with the highest increase occurring in regional NICUs. By 2013, 81.3% of premature infants cared for in regional NICUs had access to DHM. Of the 22 hospitals that had a clear transition to having availability of DHM, there was a 10% increase in breast milk feeding at NICU discharge and a concomitant 2.6% decrease in NEC rates. CONCLUSIONS: The availability of DHM has increased over time and has been associated with positive changes including increased breast milk feeding at NICU discharge and decrease in NEC rates.

Maternal Versus Infant Vitamin D Supplementation During Lactation: A Randomized Controlled Trial.

OBJECTIVE: Compare effectiveness of maternal vitamin D3 supplementation with 6400 IU per day alone to maternal and infant supplementation with 400 IU per day. METHODS: Exclusively lactating women living in Charleston, SC, or Rochester, NY, at 4 to 6 weeks postpartum were randomized to either 400, 2400, or 6400 IU vitamin D3/day for 6 months. Breastfeeding infants in 400 IU group received oral 400 IU vitamin D3/day; infants in 2400 and 6400 IU groups received 0 IU/day (placebo). Vitamin D deficiency was defined as 25-hydroxy-vitamin D (25(OH)D) <50 nmol/L. 2400 IU group ended in 2009 as greater infant deficiency occurred. Maternal serum vitamin D, 25(OH)D, calcium, and phosphorus concentrations and urinary calcium/creatinine ratios were measured at baseline then monthly, and infant blood parameters were measured at baseline and months 4 and 7. RESULTS: Of the 334 mother-infant pairs in 400 IU and 6400 IU groups at enrollment, 216 (64.7%) were still breastfeeding at visit 1; 148 (44.3%) continued full breastfeeding to 4 months and 95 (28.4%) to 7 months. Vitamin D deficiency in breastfeeding infants was greatly affected by race. Compared with 400 IU vitamin D3 per day, 6400 IU/day safely and significantly increased maternal vitamin D and 25(OH)D from baseline (P < .0001). Compared with breastfeeding infant 25(OH)D in the 400 IU group receiving supplement, infants in the 6400 IU group whose mothers only received supplement did not differ. CONCLUSIONS: Maternal vitamin D supplementation with 6400 IU/day safely supplies breast milk with adequate vitamin D to satisfy her nursing infant's requirement and offers an alternate strategy to direct infant supplementation.
