covid 19 epidemic has caused a lot of concern especially in the obstetric and neonatal populations. The fact that it is a new disease and the fact that there are sparse studies available have doubled our worries. Our study provides some answers. This a retrospective study carried out in Mediclinic Al-Noor hospital in Abu Dhabi. Our study revealed no adverse effects on the neonates and no vertical transmission. Given the physiologic and immune function changes in pregnancy, they might be considered at a higher risk of developing more complications, but it needs a longer duration of the study with larger sample size. Statistical analysis could not be possible in our study due to the smaller sample size, and we plan to continue the study further in the future to obtain a larger pool of data to validate the findings more accurately. The incidence of covid positive mothers might not reflect today’s covid situation because we carried out the study during the lockdown and there might be an increase in the incidence after lockdown.

Background :Anxiety and depression are two common psychiatric conditions encountered in cancer treatment. Prevalence rate and risk factors show wide variations in different countries and the environment. COVID 19 outbreak has increased psychological disorders in general public and health workers. Whether this pandemic has increased the psychiatric morbidity in cancer patients needs to be addressed for planning strategies. Methods: This cross-sectional study was conducted in the Department of Radiation Oncology, a tertiary cancer centre in the state of Kerala, India. The aim was to assess hospital prevalence and risk factors of anxiety and depression among cancer patients during COVID 19 pandemic. Patients on treatment for cancer and willing for the study were recruited. Hospital Anxiety and Depression Scale (HADS), a self-assessment valid tool for screening both anxiety (HADS-A) and depression (HADS-D) are used. HADS-A & D were calculated separately & categorized as normal, borderline and abnormal with a score of 0 - 7, 8 - 10 & 11 -

Objective: To describe the implementation and outcomes of using telehealth in combination with a differentiated ART delivery model to improve HIV antiretroviral therapy pick up at a large treatment facility in Trinidad and Tobago during covid-19. Design and Methods: Beginning in April 2020, a list of patients was generated daily prior to their scheduled ART appointments. Nurses, doctors and social workers conducted telephone consultations to first screen patients for covid-19 symptoms, conducted brief medical and behavioural health screenings, and helped patients to identify barriers to ART retention. Patients were recommended for 1) fast track ART refill collection at facility, 2) community ART refills, and 3) ART pick-up through patient peers. The uptake and outcomes of telehealth and ART pick up were compared with the corresponding period in 2019. Data was analyzed using SPSS 21.0. Results: During the period April-June 2020, 1361 patients were identified for telephone consultations, 1084 (80%) were successfully contacted and 984 patients (88%) participated in phone session. The independent t test showed a significant increase in ART pick-up when compared to the corresponding period in 2019. 59% of patients collected via fast-track ART refill, 30% had community refills, and 11% pick-up medications through patient peers. Conclusion: Telehealth is an integral component of DSD as part of the covid-19 response at the MRF. Understanding the medium and longer-term outcomes of Telehealth can provide additional insights on the scale up of telehealth as a component of DSD to improve ART outcomes for patients in the context of the developing countries of the Caribbean.

The aim of this study was to find a simple and effective way to screen patients for covid 19, prior to them being submitted to neurophysiological or neuro-psycholoigical testing in order to protect employees from being infected during the pandemic from patient contact. On May 18, 2020 when Michigan, a critically affected pandemic area, reopened for medical business after lockdown declared by the Governor on March 23, 2020, medical personnel in our office-which is an academic neurology practice-EEG and sleep technicians, medical Assistants, physician assistants and myself fretted about potential covid 19 transmission during neuro-diagnostic procedures-EEG, video-EEG, ambulatory EEG, PSG, MSLT, CPAP titration, neuropsychological testing, EMG/NCV, VNG/Balance test and autonomic testing including the tilt table test, which require an intimate patient contact and risk of exposure. We screened all unselected and consecutive patients who were scheduled for neuro-diagnostic testing in our facility by infrared thermometer, a standard covid 19 questionnaire and a single covid 19 PCR nasal/throat swab prior to these tests. 542 consecutive unselected neurological or sleep/wake disorder patients aged 18 - 90, 65% males, 35% females were tested over six months as a part of this project. A total of 1109 diagnostic tests were performed. No test was limited in scope or duration. Standard PPE precautions were still taken despite the negative screening, room door left open and relatives’ presence limited during the test procedure. All were afebrile and negative on questionnaire and only 3 were found to be positive for covid 19 PCR, indicating that a negative infrared temperature reading and a standard covid 19 questionnaire is over 99 percent effective in prescreening for intimate neurological diagnostic testing. The technician, administering most of these tests, never contracted the virus. The technician collecting the nasal/throat swab never contracted the virus. One PA, two sleep t

Background. The covid 19 pandemic affected healthcare delivery systems worldwide. There was a redistribution of health care resources in order to deal with the effects of the pandemic, with a corresponding consequence on other clinical services rendered. The extent of this effect on other non covid 19 related services has been reported in other centres worldwide. In our own setting, health care resources are limited with suboptimal access even in normal situations. Objective. We sought to evaluate the effects of the covid 19 pandemic on elective surgical services in our hospital. Methods. This was a cross sectional comparative study carried out at the Jos University Teaching hospital, (North central, Nigeria) of the elective surgical services rendered during the first wave of the covid 19 pandemic lockdown covering the period April to June 2020 with a corresponding period of the preceding year 2019. Data was obtained from the hospital records department, theatres and service areas for clinic attendance, elective surgeries and ward occupancy. The paired sample t-test was used to compare the assessed variables across the three months of both years with a level of significance of P Results. There was mean clinic attendance of 2859.33 ± 223.36 covering the three months in 2019 as against a mean attendance of 648.67 ± 578.24 covering a similar period in 2020, P = 0.037. The elective surgical procedures carried out across the surgical specialties over the period in 2019 gave a mean of 352.33 ± 44.60 as opposed to 64.001 ± 7.32 over the corresponding period in 2020, P = 0.018. Ward occupancy over April to June 2019 was a mean 297.33 ± 18.58 across the various surgical wards and 158.33 ± 25.70 in the same period in 2020, P = 0.007. Conclusion. There was a significant reduction in the elective surgical services rendered in the hospital during the first wave of the covid 19 pandemic c
