Asian and non-Asian referrals to the department of child psychiatry at the London Hospital in 1987 were analysed. Asian referrals were under-represented with respect to the local population but, contrary to our expectations, there were no significant differences between the groups with regard to demographic data, the nature of the presenting problem, and attrition rates.

The Impact

Introduction: Atypical pneumonia known as coronavirus disease (COVID-19), which is caused by the SARS-CoV-2 virus, is highly infectious and is currently spreading rapidly around the globe. Objectives: The main objective of the study is to analyses the impact of COVID-19 on pregnancy outcomes among local population of Pakistan. Material and Methods: This cross sectional observational study was conducted in Lady Aitchison Hospital during September 2019 to August 2020. The data was collected through systematically designed questionnaire. Clinical characteristics, examination results, and treatment course were extracted from their medical records. For mothers, we collected socio demographic data, educational attainment, and occupation, maternal parity, medical history records, laboratory tests, and intensive care unit [ICU] admission. Results: The data was collected from 685 patients. The two groups of pregnant women were compared in terms of severe preeclampsia, gestational diabetes, premature rupture of membranes, fetal distress, maternal mortality, IUD, fecal staining of amniotic fluid, premature birth, neonatal asphyxia, Abruption or other compression sutures, and there was no significant difference Significance (all P >0.05); the proportion of IUD in the COVID-19 group was higher than that in the non COVID-19 group, and the difference between the two groups was statistically significant. Conclusion: It is concluded that those patients who visited the hospital during COVID-19 pandemics have high rate of IUD, placenta abruption and maternal death. Keywords: IUD., COVID-19

ABSTRACTLongitudinal studies are examined with special reference to the Ontario Longitudinal Study of Aging (LSA). The specific aspects discussed are the representativeness of the sample, attrition rates, end-points, and associations, particularly the associations with age. It is concluded that, in comparison with other longitudinal studies, both in Canada and the U.S., the LSA represents a good source of longitudinal data and therefore lends itself to analyses which may be used to investigate factors expected to be important in understanding various aspects of the aging process.

Near Extinction

Understanding and identifying drivers of local population declines are important in mitigating future risks and optimising conservation efforts. The Knysna elephants have, after being afforded protection since the early 1900s, declined to near extinction today. We propose three hypotheses as to why the Knysna elephant population declined. The refugee hypothesis suggests that anthropogenic activities forced the elephants to take refuge in the forest and that the low-quality food acted as the primary driver of decline. The illegal killing hypothesis suggests that the elephants adapted to the forest and its immediate fynbos habitat, with the decline being a consequence of illegal kills. The stochastic founder population hypothesis postulates that the population size and structure left it vulnerable to demographic stochasticity. We critically reviewed available evidence for these hypotheses and found that, although the historical elephant range decline most likely resulted through the refugee hypothesis, the weak demographic and life-history information limits elimination of either of the other hypotheses. We touch on the implications for decision-makers and draw attention to information requirements. Significance: • We highlight the knowledge and management challenges which exist for small, threatened populations of which long-term demographic data are sparse. • We provide the first unbiased evaluation of multiple drivers that may have caused the decline of the Knysna elephants.

A local population of Tasmanian long-tailed mice, Pseudomys higginsi, occupying an area of wet sclerophyll forest at low density was studied for 13 months using mark-recapture techniques. Individuals in the trappable population were readily recaught (29 individuals caught 183 times). Demographic data are presented for a single age cohort born in 1989 (21 individuals trapped 126 times) and surviving until the end of the trapping programme (April 1990). Habitat use was investigated by comparing data from individuals active within four contiguous areas of forest displaying structural and floristic heterogeneity. Trap-revealed habitat use indicated that P. higginsi was completely absent from areas of thickest ground cover where densities of the sympatric murid, Rams lutreolus velutinus, were highest. Conversely, captures of P. higginsi were highest in areas of boulder scree where captures of R. 1. velutinus were lower than expected. Relative numbers of individuals active in each macrohabitat group are examined and a role for interspecific competition between these rodent species is inferred.

Abstract Aim Brachiocephalic fistulas (BCFs) are the most commonly used arteriovenous fistulas (AVFs). They are commonly associated with cephalic arch stenosis (CAS), a leading cause of dysfunction and failure. The 2018 European Society of Vascular Surgery guidelines recommend the consideration of stent grafts for managing CAS. In this study, we sought to evaluate the management of CAS in a North London hospital. Method We carried out a retrospective study of patients who had undergone a fistulogram/fistuloplasty for CAS between May 2014 and May 2020. We extracted demographic data, information about their access, and information regarding surgical management of CAS, from the patients’ records on VitalData. We extracted data about recurrence of CAS from their Cerner records. Results Seventy patients were included. 54.3% were still alive at the time of data collection. The average age of those still alive was 65.8±14.1 years. 78.6% had a left BCF. 66% had previous access. 4.29% underwent stenting for CAS. The rest had fistulopasties alone. 90% required multiple fistulopaslties (mean=3.44±1.51). Median interval between access creation and first fistuloplasty was 1.90 years. 34.3% of patients underwent surgical repair of their AVF. AVF failure rate was 34.3%. Median interval between access creation and failure was 3.05 years. Median interval between first fistuloplasty and access failure was 1.34 years. Conclusions Our data demonstrate a high rate of access failure in patients with CAS treated at our centre. Few of our patients had stent grafts inserted. The majority had fistuloplasties without stenting, which was associated with a high recurrence rate.
