Duplication errors due to brand name confusion; It is not always the name-Short case series. Clin Case Rep 2023; 11:e7795. [PMID: 37720712 PMCID: PMC10502196 DOI: 10.1002/ccr3.7795] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 04/14/2023] [Accepted: 05/05/2023] [Indexed: 09/19/2023] Open
Abstract
Confusion of drug names has been identified as a leading cause of medication errors and potential iatrogenic harm. Most of these errors occur because of look-alike or sound-alike drugs. This case series gives examples of duplication errors due to brand confusion, where there are no similarities in the names.

Abstract
Caregivers are primarily responsible for the administration of Over The Counter (OTC) medications in children. This study examines the mothers' ability to determine and measure paracetamol doses for children aged between 1 and 5 years. A contrived observational study was conducted for mothers of preschool aged children at two Public Health Midwifery (PHM) areas in Southern province, Sri Lanka. Stratified random sampling was used. Only 26.9% (n = 95, 95% CI = 22.5%-31.7%) of the 353 participants correctly determined and measured the doses of paracetamol. Errors were frequently made in both determining and measuring dose together (n = 113, 32.0%, 95% CI = 27.3%-37.1%), determining only (n = 94, 26.6%, 95% CI = 22.2%-31.5%) and measurement only (n = 51, 14.4%, 95% CI = 11.1%-18.5%). Dose determined errors were not significantly associated with maternal education, number of children in the family, total monthly income and age of the index child. Similarly measuring errors were not significantly associated with mothers' education, income of the family and number of children in the family. However, there was a weak positive correlation between measuring errors and age of the index child. The study suggests that mothers made errors when determining doses and measuring doses of paracetamol. Results emphasize importance of clear, concise guardian information leaflet and healthcare professionals' guidance to minimize dosing errors of child medication.

Abstract
Abstract
Introduction
Cardiopulmonary exercise testing (CPEX) provides valuable diagnostic and prognostic cardiopulmonary function data. However, in clinical setting a maximal test is not always achievable. The Oxygen Efficiency Uptake Slope (OUES) has been proposed as a possible submaximal measure of cardiopulmonary function as it remains relatively stable during the final quartile of the exercise test. This study explored the validity of OUES as a surrogate marker for cardiopulmonary function in the event of a submaximal test.
Methods
Four groups of subjects [128 healthy controls (73 M), 44 asymptomatic hypertensive (HT) patients (26 M), 67 adult cardiac congenital heart disease (ACHD) patients (44 M) and 35 Heart Failure with preserved Ejection Fraction (HFpEF) (10M) patients] were recruited after informed consent. All subjects underwent clinical assessment, resting ECG, blood pressure and spirometry prior to a treadmill CPEX to volitional exhaustion and a respiratory exchange ratio (RER) of at least 1.1 using the same testing protocol. Peak VO2 (ml/min) was recorded from the last 5s of the maximal test (RER=1.1) and OUES was calculated from complete (RER=1.1) and truncated (RER=0.9) gas exchange data. The linear relationships between absolute peak VO2 and OUES from complete and truncated gas exchange data were assessed using Pearson's correlation coefficient. Subsequently, the two correlations obtained in each patient group were compared. Statistical significance was set at p<0.01.
Results
Mean and 95% confidence intervals of the peak VO2 for males and females in each decile of life examined in the 4 subject groups are shown in the Figure. Peak VO2 values achieved in each of the patient groups were significantly lower when matched for age and sex compared to healthy participants (HT p=0.006, ACHD patients p<0.001 and HFpEF patients p<0.001).
In all 4 groups there was a good correlation between absolute peak VO2 and the OUES at RER 1.1 (healthy volunteers r=0.910, p<0.001, HT r=0.899, p<0.001, ACHD r=0.816, p<0.001 and HFpEF r=0.846, p<0.001). Correlations were inferior for absolute peak VO2 and OUES at RER 0.9 (healthy volunteers r=0.74, p<0.001, HT r=0.780, p<0.001, ACHD r=0.651, p<0.001 and HFpEF r=0.817, p<0.001). Correlations between absolute peak VO2 vs OUES at RER of 1.1 and 0.9 were significantly different only for healthy controls (p=0.001, Z-score = −4.649), but not for HT (p=0.05, Z-score = −1.909), ACHD (p=0.04, Z-score = −2.080) or HFpEF (p=0.7, Z-score = −0.377) patients.
Conclusion
Our data support the use of submaximal OUES at an RER of 0.9 as a surrogate marker for absolute peak VO2 obtained at an RER of 1.1, especially in patients, in whom it can often be difficult to achieve maximal exercise.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study. Lancet Digit Health 2022; 4:e520-e531. [PMID: 35750401 DOI: 10.1016/s2589-7500(22)00069-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Revised: 01/07/2022] [Accepted: 04/06/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Abstract
Changes in woody biomass over centuries to millennia are poorly known, leaving unclear the magnitude of terrestrial carbon fluxes before industrial-era disturbance. Here, we statistically reconstructed changes in woody biomass across the upper Midwestern region of the United States over the past 10,000 years using a Bayesian model calibrated to preindustrial forest biomass estimates and fossil pollen records. After an initial postglacial decline, woody biomass nearly doubled during the past 8000 years, sequestering 1800 teragrams. This steady accumulation of carbon was driven by two separate ecological responses to regionally changing climate: the spread of forested biomes and the population expansion of high-biomass tree species within forests. What took millennia to accumulate took less than two centuries to remove: Industrial-era logging and agriculture have erased this carbon accumulation.

Abstract
Abstract
Introduction
During the COVID pandemic, the 2019-2020 cohort of final year students were invited to participate in Foundation interim Year 1 placements (FiY1). FiY1 aimed to ease transition to Foundation Year 1 doctor (FY1). We assessed the psychological impact of FiY1 on final year medical students.
Method
A cross-sectional survey was distributed to final year medical students in the UK between June 4th and July 4th, 2020. The survey contained the following domains: participant demographics, rationale for FiY1 participation, a checklist of the key safety principles for FiY1s, the Hospital Anxiety and Depression Scale and the Perceived Stress scale-4.
Results
107 final years responded to the survey. 72.0% (n = 77) of final year students surveyed were working as FiY1s. Final year students participating in FiY1 postings had reduced rates of anxiety (29.9% vs 43.4%, P = 0.186), depression (5.2% vs 20.0%, P = 0.018) and lower perceived stress levels (5.0 vs 7.2, P < 0.001). 19.5% (15/77) FiY1s reported working beyond their competency, 27.3% (22/77) felt unsupervised, but 94.8% (73/77) of FiY1s felt the post prepared them for FY1.
Conclusions
Students participating in FiY1 postings felt less stressed and depressed than those not participating in the scheme and the majority felt it was preparing them for FY1.

Aboriginal community controlled health organisations address health equity through action on the social determinants of health of Aboriginal and Torres Strait Islander peoples in Australia. BMC Public Health 2020; 20:1859. [PMID: 33276747 PMCID: PMC7716440 DOI: 10.1186/s12889-020-09943-4] [Citation(s) in RCA: 32] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2020] [Accepted: 11/19/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Indigenous populations globally are continually striving for better health and wellbeing due to experiencing significant health and social inequities. The social determinants of health are important contributors to health outcomes. Comprehensive primary health care that is governed and delivered by Indigenous people extends beyond the biomedical model of care to address the social determinants of health. Aboriginal Community Controlled Health Organisations (ACCHOs) are known to provide culturally informed, holistic health services that directly and indirectly address the social determinants of health. The range and extent of their activities in addressing the social determinants of health, however, is not well documented. METHODS The most recent ACCHO annual reports were retrieved online or by direct correspondence. For coding consistency, a dictionary informed by the World Health Organization's Conceptual Framework for Action on the Social Determinants of Health was developed. A document and textual analysis of reports coded ACCHO activities and the determinants of health they addressed, including intermediary determinants, socio-economic position and/or socio-political context. Summary statistics were reported. Representative quotes illustrating the unique nature of ACCHO service provision in addressing the social determinants of health were used to contextualise the quantitative findings. RESULTS Sixty-seven annual reports were collected between 2017 and 2018. Programs were delivered to population groups across the life span. Fifty three percent of reports identified programs that included work at the socio-political level and all annual reports described working to improve socioeconomic position and intermediary determinants of health through their activities. Culture had a strong presence in program delivery and building social cohesion and social capital emerged as themes. CONCLUSIONS This study provides evidence of the considerable efforts of the ACCHO sector, as a primary health care provider, in addressing the social determinants of health and health inequity experienced by Indigenous communities. For the Aboriginal and Torres Strait Islander population, ACCHOs not only have an essential role in addressing immediate healthcare needs but also invest in driving change in the more entrenched structural determinants of health. These are important actions that are likely to have an accumulative positive effect in closing the gap towards health equity.

Abstract
Sarcopenia and osteoporosis are associated with poor health outcomes in older people. Relationships between muscle and bone have typically been reported at a functional or macroscopic level. The aims of this study were to describe the relationships between muscle morphology and bone health among participants of the Hertfordshire Sarcopenia Study (HSS). 105 older men, mean age 72.5 (SD 2.5) years, were recruited into the HSS. Whole body lean mass as well as appendicular lean mass, lumbar spine and femoral neck bone mineral content (BMC) and bone mineral density (BMD) were obtained through dual-energy X-ray absorptiometry scanning. Percutaneous biopsy of the vastus lateralis was performed successfully in 99 participants. Image analysis was used to determine the muscle morphology variables of slow-twitch (type I) and fast-twitch (type II) myofibre area, myofibre density, capillary and satellite cell (SC) density. There were strong relationships between whole and appendicular lean body mass in relation to femoral neck BMC and BMD (r ≥ 0.43, p < 0.001). Type II fibre area was associated with both femoral neck BMC (r = 0.27, p = 0.01) and BMD (r = 0.26, p = 0.01) with relationships robust to adjustment for age and height. In unadjusted analysis, SC density was associated with whole body area (r = 0.30, p = 0.011) and both BMC (r = 0.26, p = 0.031) and area (r = 0.29, p = 0.017) of the femoral neck. We have demonstrated associations between BMC and changes in muscle at a cellular level predominantly involving type II myofibres. Interventions targeted at improving muscle mass, function and quality may improve overall musculoskeletal health. Larger studies that include women are needed to explore these relationships further.

Photon Doppler velocimetry measurements of transverse surface velocities. THE REVIEW OF SCIENTIFIC INSTRUMENTS 2018; 89:063106.

Abstract
The goal of this work was to develop a technique for making transverse surface velocity measures utilizing Photon Doppler Velocimetry (PDV). Such a task is achieved by transmitting light and collecting Doppler-shifted light at an angle relative to the normal axis, where measured velocities are representative of a component of the transverse velocity. Because surface characteristics have an intrinsic effect on light scatter, different surface preparations were explored to direct reflectivity, including diffusion by means of sandpapering, or increasing retroreflectivity by coating with microspheres, milling v-cuts, and electrochemically etching grooves. Testing of these surface preparations was performed using an experiment featuring a 30 mm diameter aluminum disk rotating at 6000 or 6600 RPM. A single PDV collimator was positioned along the rotational axis of the disk at various angles, resolving the apparent transverse velocity. To characterize surface preparations, light return and velocities were recorded as a function of probe angle ranging from 0° to 51° from the surface normal for each preparation. Polished and electrochemically etched surfaces did not provide enough reflected light to resolve a beat frequency; however, sandpapered surfaces, retroreflective microspheres, and milled v-cuts provided adequate reflected light for incidence angles up to 51°. Applications of the surface preparations were then studied in gas gun experiments. Retroreflective microspheres were studied in a planar impact experiment, and milled v-cuts were studied in an oblique impact experiment. A normal and transverse profile of particle velocity was resolved in the oblique impact experiment.

Abstract
BACKGROUND Newer endothelin receptor antagonists (ERAs) used to treat patients with pulmonary arterial hypertension (PAH) are associated with fewer drug-drug interactions than bosentan and require less monitoring. This, combined with a pharmacokinetic basis for improved efficacy, means there may be a clinical rationale for changing therapies. However, this can be challenging and few data on its safety in patients with PAH are available. AIMS At the Royal Free Hospital in London, UK, home-based medication transitioning has been standard practice since 2009 to avoid unnecessary hospital visits for patients, unless there is a clinical imperative. In this audit of standard practice we evaluated the consequences of adopting such a strategy when transitioning PAH patients between ERA therapies. METHODS AND RESULTS Using a Clinical Nurse Specialist-led, home-based transitioning strategy, 92 patients with PAH were transitioned from bosentan to macitentan or ambrisentan. Observational data were analysed retrospectively. The majority of patients were female with PAH associated with connective tissue disease and their ERA was changed in the hope of improving efficacy. The process was well tolerated with no adverse events associated with the process. Seventeen patients died during the study (macitentan, n = 5; ambrisentan, n = 12). None of the deaths was considered related to ERA treatment. The majority of patients remained clinically stable, based on WHO functional class and exercise capacity. CONCLUSION An established home-based transitioning strategy can be adopted safely for patients with PAH changing ERA therapies. Most patients remained stable and the therapy change was well tolerated.

Abstract
OBJECTIVES In this article, we outline the link between migration, public health and ethics. STUDY DESIGN Discussing relevant arguments about migration from the perspective of public health and public health ethics. METHODS Critical review of theories and frameworks, case-based analysis and systematic identification and discussion of challenges. RESULTS Migration is a core issue of public health ethics and must take a case-based approach: seeking to identify the specific ethical dimensions and vulnerabilities in each particular context. Public health as a practice, built upon the core value of justice, requires the protection and promotion of migrants' well-being (even if this produces tension with immigration services). Ethical analysis should take all phases of migration into account: before, during and after transit. We argue that migration policies, at least as they relate to migrants' well-being, should be founded upon a shared humanity, respect for human rights and on the idea that effective public health cannot and should not be confined within the borders and to the citizens of any host country. CONCLUSIONS We make the case for migration to be seen as a core issue of public health ethics.

Abstract
UNLABELLED This systematic review summarizes the effect of combined exercise and nutrition intervention on muscle mass and muscle function. A total of 37 RCTs were identified. Results indicate that physical exercise has a positive impact on muscle mass and muscle function in subjects aged 65 years and older. However, any interactive effect of dietary supplementation appears to be limited. INTRODUCTION In 2013, Denison et al. conducted a systematic review including 17 randomized controlled trials (RCTs) to explore the effect of combined exercise and nutrition intervention to improve muscle mass, muscle strength, or physical performance in older people. They concluded that further studies were needed to provide evidence upon which public health and clinical recommendations could be based. The purpose of the present work was to update the prior systematic review and include studies published up to October 2015. METHODS Using the electronic databases MEDLINE and EMBASE, we identified RCTs which assessed the combined effect of exercise training and nutritional supplementation on muscle strength, muscle mass, or physical performance in subjects aged 60 years and over. Study selection and data extraction were performed by two independent reviewers. RESULTS The search strategy identified 21 additional RCTs giving a total of 37 RCTs. Studies were heterogeneous in terms of protocols for physical exercise and dietary supplementation (proteins, essential amino acids, creatine, β-hydroxy-β-methylbuthyrate, vitamin D, multi-nutrients, or other). In 79% of the studies (27/34 RCTs), muscle mass increased with exercise but an additional effect of nutrition was only found in 8 RCTs (23.5%). Muscle strength increased in 82.8% of the studies (29/35 RCTs) following exercise intervention, and dietary supplementation showed additional benefits in only a small number of studies (8/35 RCTS, 22.8%). Finally, the majority of studies showed an increase of physical performance following exercise intervention (26/28 RCTs, 92.8%) but interaction with nutrition supplementation was only found in 14.3% of these studies (4/28 RCTs). CONCLUSION Physical exercise has a positive impact on muscle mass and muscle function in healthy subjects aged 60 years and older. The biggest effect of exercise intervention, of any type, has been seen on physical performance (gait speed, chair rising test, balance, SPPB test, etc.). We observed huge variations in regard to the dietary supplementation protocols. Based on the included studies, mainly performed on well-nourished subjects, the interactive effect of dietary supplementation on muscle function appears limited.

Abstract
Behaviour change, specifically that which decreases cancer risk, is an essential element of cancer control. Little information is available about how awareness of risk factors may be changing over time. This study describes the awareness of cancer risk behaviours among adult New Zealanders in two cross-sectional studies conducted in 2001 and 2014/5.Telephone interviews were conducted in 2001 (n = 436) and 2014/5 (n = 1064). Participants were asked to recall things they can do to reduce their risk of cancer. They were then presented with a list of potential risk behaviours and asked if these could increase or decrease cancer risk.Most New Zealand adults could identify at least one action they could take to reduce their risk of cancer. However, when asked to provide specific examples, less than a third (in the 2014/5 sample) recalled key cancer risk reduction behaviours such as adequate sun protection, physical activity, healthy weight, limiting alcohol and a diet high in fruit. There had been some promising changes since the 2001 survey, however, with significant increases in awareness that adequate sun protection, avoiding sunbeds/solaria, healthy weight, limiting red meat and alcohol, and diets high in fruit and vegetables decrease the risk of developing cancer.

Domoic Acid Poisoning as a Possible Cause of Seasonal Cetacean Mass Stranding Events in Tasmania, Australia. BULLETIN OF ENVIRONMENTAL CONTAMINATION AND TOXICOLOGY 2017; 98:8-13.

Abstract
The periodic trend to cetacean mass stranding events in the Australian island state of Tasmania remains unexplained. This article introduces the hypothesis that domoic acid poisoning may be a causative agent in these events. The hypothesis arises from the previously evidenced role of aeolian dust as a vector of iron input to the Southern Ocean; the role of iron enrichment in Pseudo-nitzschia bloom proliferation and domoic acid production; and importantly, the characteristic toxicosis of domoic acid poisoning in mammalian subjects leading to spatial navigation deficits. As a pre-requisite for quantitative evaluation, the plausibility of this hypothesis was considered through correlation analyses between historical monthly stranding event numbers, mean monthly chlorophyll concentration and average monthly atmospheric dust loading. Correlation of these variables, which under the domoic acid stranding scenario would be linked, revealed strong agreement (r = 0.80-0.87). We therefore advocate implementation of strategic quantitative investigation of the role of domoic acid in Tasmanian cetacean mass stranding events.

Disorders of sex development: insights from targeted gene sequencing of a large international patient cohort. Genome Biol 2016; 17:243. [PMID: 27899157 PMCID: PMC5126855 DOI: 10.1186/s13059-016-1105-y] [Citation(s) in RCA: 188] [Impact Index Per Article: 23.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2016] [Accepted: 11/10/2016] [Indexed: 01/20/2023] Open
Abstract
Background Disorders of sex development (DSD) are congenital conditions in which chromosomal, gonadal, or phenotypic sex is atypical. Clinical management of DSD is often difficult and currently only 13% of patients receive an accurate clinical genetic diagnosis. To address this we have developed a massively parallel sequencing targeted DSD gene panel which allows us to sequence all 64 known diagnostic DSD genes and candidate genes simultaneously. Results We analyzed DNA from the largest reported international cohort of patients with DSD (278 patients with 46,XY DSD and 48 with 46,XX DSD). Our targeted gene panel compares favorably with other sequencing platforms. We found a total of 28 diagnostic genes that are implicated in DSD, highlighting the genetic spectrum of this disorder. Sequencing revealed 93 previously unreported DSD gene variants. Overall, we identified a likely genetic diagnosis in 43% of patients with 46,XY DSD. In patients with 46,XY disorders of androgen synthesis and action the genetic diagnosis rate reached 60%. Surprisingly, little difference in diagnostic rate was observed between singletons and trios. In many cases our findings are informative as to the likely cause of the DSD, which will facilitate clinical management. Conclusions Our massively parallel sequencing targeted DSD gene panel represents an economical means of improving the genetic diagnostic capability for patients affected by DSD. Implementation of this panel in a large cohort of patients has expanded our understanding of the underlying genetic etiology of DSD. The inclusion of research candidate genes also provides an invaluable resource for future identification of novel genes.

Abstract
The study of inflammatory bowel disease, including Ulcerative Colitis and Crohn's Disease, has relied largely upon the use of animal or cell culture models; neither of which can represent all aspects of the human pathophysiology. Presented herein is a dual flow microfluidic device which holds full thickness human intestinal tissue in a known orientation. The luminal and serosal sides are independently perfused ex vivo with nutrients with simultaneous waste removal for up to 72 h. The microfluidic device maintains the viability and integrity of the tissue as demonstrated through Haematoxylin & Eosin staining, immunohistochemistry and release of lactate dehydrogenase. In addition, the inflammatory state remains in the tissue after perfusion on the device as determined by measuring calprotectin levels. It is anticipated that this human model will be extremely useful for studying the biology and testing novel interventions in diseased tissue.

Abstract
OBJECTIVES To examine the association of sociodemographic, antenatal and delivery care factors with the essential newborn care (ENC) practices of neonates born at home in Bangladesh. STUDY DESIGN This study analyzed data of a cross-sectional survey-the Bangladesh Demographic and Health Survey, 2011. METHODS This analysis considered 3190 most recent live-born infants who were delivered at home within three years of the survey. Logistic regression models were used to identify the factors affecting the implementation of six ENC practices, namely using disinfected instruments to cut the umbilical cord, avoidance of application of any substances to the umbilical cord stump, immediate drying and wrapping of newborns, delayed bathing of newborns, and immediate initiation of breastfeeding. RESULTS Factors affecting ENC practices in Bangladesh are low parental education, low utilization of antenatal care services, the absence of skilled birth attendants, smaller size at birth, higher birth order and mother's age at birth. Regional factors also seem to considerably affect ENC practices. CONCLUSION There is ample scope to improve the coverage of ENC practices in Bangladesh. Health promotion programmes that target parents with low education and older mothers may help to build awareness of ENC practices. This investigation provides insight into the key determinants of ENC practices, which require consideration when scaling up ENC practices in low-income and lower middle-income countries.

Abstract
The rhythm of life on earth is shaped by seasonal changes in the environment. Plants and animals show profound annual cycles in physiology, health, morphology, behaviour and demography in response to environmental cues. Seasonal biology impacts ecosystems and agriculture, with consequences for humans and biodiversity. Human populations show robust annual rhythms in health and well-being, and the birth month can have lasting effects that persist throughout life. This review emphasizes the need for a better understanding of seasonal biology against the backdrop of its rapidly progressing disruption through climate change, human lifestyles and other anthropogenic impact. Climate change is modifying annual rhythms to which numerous organisms have adapted, with potential consequences for industries relating to health, ecosystems and food security. Disconcertingly, human lifestyles under artificial conditions of eternal summer provide the most extreme example for disconnect from natural seasons, making humans vulnerable to increased morbidity and mortality. In this review, we introduce scenarios of seasonal disruption, highlight key aspects of seasonal biology and summarize from biomedical, anthropological, veterinary, agricultural and environmental perspectives the recent evidence for seasonal desynchronization between environmental factors and internal rhythms. Because annual rhythms are pervasive across biological systems, they provide a common framework for trans-disciplinary research.

Abstract
OBJECTIVE To assess the impact of essential newborn care (ENC) practices on the mortality of neonates delivered at home in Bangladesh. STUDY DESIGN This study used cross-sectional data from the 2011 Bangladesh Demographic and Health Survey. Adjusted logistic regression model was used to examine the effect of ENC practices on neonatal mortality based on 3190 live-born infants. RESULT Delayed bathing (72 h after delivery) significantly contributed to reducing neonatal mortality. A significant but counterintuitive relation was observed between the dry cord care and neonatal deaths. CONCLUSION Neonatal mortality may be reduced through emphasizing delayed bathing. Specific guidelines on the cleanliness of the fabric used to dry and wrap newborns, as well as emphasizing the use of clean delivery kits and initiation of immediate and exclusive breastfeeding, may improve neonatal outcomes. Further, the ENC guidelines in Bangladesh should include the application of topical antiseptics to the cord stump.

Abstract
This prospective experimental simulation study evaluated the efficiency, ease of use (EOU) and cost of administering chemotherapy with two closed system transfer devices (CSTD, Equashield™ and PhaSeal® ) and no CSTD. Forty-six veterinary technicians (VT) working in oncology specialty practices were timed during chemotherapy administration simulated with water and a model canine limb 10 times with each system and with no CSTD. EOU and likelihood of recommending each system were rated by VT using visual analog scales. Costs were obtained from veterinary distributors. Administration was fastest with Equashield™ (P = 0.0003), but the difference was not enough to affect case flow. Equashield™ was easier to use than PhaSeal® or no CSTD (P = 0.002), however VT recommended both CSTD more strongly than no CSTD (P < 0.0001). Equashield™ cost less than PhaSeal® but was sold only in bulk quantities. CSTD did not decrease efficiency in administering chemotherapy and were readily accepted by VT.

Detoxification enzyme activities (CYP1A1 and GST) in the skin of humpback whales as a function of organochlorine burdens and migration status. AQUATIC TOXICOLOGY (AMSTERDAM, NETHERLANDS) 2014; 155:207-12.

Abstract
The activities of glutathione-s-transferase (GST) and cytochrome P-450 1A1 (CYP1A1) enzymes were measured in freshly extracted epidermis of live-biopsied, migrating, southern hemisphere humpback whales (Megaptera novaeangliae). The two quantified enzyme activities did not correlate strongly with each other. Similarly, neither correlated strongly with any of the organochlorine compound groups previously measured in the superficial blubber of the sample biopsy core, likely reflecting the anticipated low levels of typical aryl-hydrocarbon receptor ligands. GST activity did not differ significantly between genders or between northward (early migration) or southward (late migration) migrating cohorts. Indeed, the inter-individual variability in GST measurements was relatively low. This observation raises the possibility that measured activities were basal activities and that GST function was inherently impacted by the fasting state of the sampled animals, as seen in other species. These results do not support the implementation of CYP1A1 or GST as effective biomarkers of organochlorine contaminant burdens in southern hemisphere populations of humpback whales as advocated for other cetacean species. Further investigation of GST activity in feeding versus fasting cohorts may, however, provide some insight into the fasting metabolism of these behaviourally adapted populations.

Abstract
ISSUE ADDRESSED This paper aims to explore the presence and role of edible gardens in Aotearoa/New Zealand Early Childhood Education Services (ECES). METHODS Participant ECES providers were identified from the Ministry of Education database of Early Childhood Education Services (March 2009). These include Education and Care and Casual Education and Care, Kindergarten, Home-based Education and Care services, Playcentres, Te Kōhanga Reo. A structured, self-administered questionnaire was sent to the Principal or Head Teacher of the service. RESULTS Of the 211 ECES that responded (55% response rate), 71% had edible gardens, incorporating vegetables, berry fruit, tree fruit, edible flowers and nut trees. Garden activities were linked with teaching across all strands of the New Zealand early childhood curriculum. In addition, 34% provided guidance on using garden produce and 30% linked the garden with messages on fruit and vegetable consumption. Most gardens were established recently (past 2 years) and relied on financial and non-financial support from parents, teachers and community organisations. Barriers included a lack of funding, space, time and staff support. CONCLUSIONS/IMPLICATIONS Study findings suggest that gardens are already being used as a versatile teaching tool in many ECES settings. Most gardens are new, with a need to support the sustainability and workforce development among teachers and parents in order to be able to maintain these resources for future generations. SO WHAT?: Given the inherent links between gardening and healthy food and exercise, there seem to be extensive opportunities for health promotion aligned with the edible garden movement.
