Abstract Aims To assess the 30-day mortality rate in patients undergoing vascular procedures in a single vascular centre during the first wave of the Covid-19 pandemic. Methods Retrospective analysis of all vascular operations undertaken at our unit from 11th March 2020 to 16th November 2020. Thirty-day mortality rate, ASA grade, 30-day Covid-19 PCR test positivity and cause of death were assessed. Mortality rate was compared to previous five-year average with a Chi- Square test. Results Within the observed period, 237 vascular operations were performed (49% operative reduction). 57 patients (24%) were operated electively through the “Green pathway” (day case) and there were no perioperative positive Covid-19 tests. 180 patients were operated through the “Amber” (elective Inpatient) or “Red” (emergency) pathway. Eight inpatients (4.4%) died within 30 days from surgery, similar to the average 30-day mortality observed in the previous years (5.9% p > 0.05). Three patients (1.42%) tested positive preoperatively but were all asymptomatic from Covid-19. One patient who died tested positive for Covid-19 but was asymptomatic from a respiratory aspect and died of cardiovascular disease. Conclusion We found no difference in 30-day post-operative mortality rate during the initial wave of Covid-19. Only 3 patients undergoing emergency operations tested positive. This study does reinforce the “Green pathway” strategy for elective patients to ensure minimising exposure to Covid-19 but we also did not witness any difference in mortality rate in the “Amber” or “Red” pathway. The impact of the second or third “wave” on current numbers will need to be studied further.

Purpose: To assess ocular pathologies admitted to Italian Emergency Eye Departments (EEDs) during the COVID-19 pandemic national lockdown in 2020 in comparison with the same period in 2019. Methods: Electronic records of all patients presenting at EEDs of two tertiary-care Eye Centers during the COVID-19 national lockdown in Italy (March 10–May 3, 2020) were compared with the equivalent period in 2019. Main outcomes were patient age, gender, and diagnoses. Statistical analysis included unpaired Student t-tests, Poisson regression, and chi-square test. Results: Overall EED visits significantly decreased by 54.1% during the 2020 lockdown compared to 2019 (851 vs 1854, p < 0.001). During lockdown, patients showed comparable mean age (52.8 years in 2020 vs 53.3 years in 2019, p = 0.52) and significant male gender bias (61.1% in 2020 vs 55.8% in 2019, p < 0.0001). The most frequent pathologies were eye inflammations, trauma-related incidents, and spontaneous acute vitreous detachment. Patients with inflammation, headache/hemicrania, and spontaneous subconjunctival hemorrhages were significantly less, whereas those with trauma-related diagnoses were significantly higher during the lockdown as compared with 2019 ( p < 0.05). The proportion of non-urgent visits decreased from 17% in 2019 to 8% in 2020 ( p < 0.001). Conclusions: During the 2020 lockdown, there was a significant reduction of accesses to EED, especially for non-urgent pathologies. Potentially visual function threatening conditions, such as trauma-related pathologies, retinal detachment or ruptures, and wet AMD, showed lower number of cases but higher or stable proportion relative to the total caseload, suggesting a correct and efficient access to ophthalmic health care during the pandemic period.

Persistent Pesticides

The current work is aimed at generating information on giant crickets and the impact of commonly used pesticides on the natural population of these crickets. Data was collected based on interviews and complemented with field observations. Out of 319 respondents surveyed, 290 were aware of the use of the giant cricket as a food source, and 161 were active consumers. Regarding the availability of the giant cricket, respondents reported that the crickets’ populations were diminishing because of farming practices. About 219 persons reported that commonly used herbicides harm giant crickets at different stages. This could be attributed to the scarcity of this species, as mentioned by 233 respondents. The results showed that 130 respondents were engaged in gathering giant crickets for consumption. This insect gathering is related to soil tilling. Chi-square test showed a significant dependence relationship between herbicides use and cricket scarcity. Although less than a majority (129) of respondents are making regular use of persistent pesticides (herbicides), it has been observed that intensive use of pesticides could become a popular practice in smallholder farming categories. This paper thus suggests the need for training and surveillance concerning the trade of pesticides in the region and proposes further investigations into pesticides residues or traces in collected giant crickets consumed in the study site and in all areas with similar conditions.

This study assessed differences in response rates to a series of three-wave mail surveys when amiable or insistently worded postcards were the third wave of the mailing. Three studies were conducted; one with a sample of 600 health commissioners, one with a sample of 680 vascular nurses, and one with 600 elementary school secretaries. The combined response rates for the first and second wave mailings were 65.8%, 67.6%, and 62.4%, respectively. A total of 308 amiable and 308 insistent postcards were sent randomly to nonrespondents as the third wave mailing. Overall, there were 41 amiable and 52 insistent postcards returned, not significantly different by chi-square test. However, a separate chi-square test for one of the three studies, the nurses' study, did find a significant difference in favor of the insistently worded postcards.

The alarming statistics of COVID-19 surges up in 2021 throwing an enormous burden on the healthcare system across the world. According to WHO reports on 14th April 2021, globally 136,996,364 confirmed COVID-19 cases are reported across the continents, including 2,951,832 deaths. The state of Maharashtra reported the maximum number of cases of India including high mortality rate. This study was conducted to identify and describe the relation of different predictors (Age, gender, duration of hospital stay, presence of co morbidities) of mortality among the COVID-19 deceased patients by retrospectively analyzing the medical case records of 121 patients from a dedicated COVID hospital at Aurangabad from July 2020 to December 2020. Chi-square test was performed to assess the association between causes of death with different cluster of variables and their significance. This study helps us to identify risk factors that show association between various predictors and mortality rate in COVID-19 patients. Out of 121 deaths, 96 (79%) were male, 61 (49.6%) were in age group between 60-79 years, ARDS was one of the major complication in the deceased patients accounting 29.8% and cardio respiratory arrest was the common cause of death among the deceased patients with 85%. It was also observed that mortality rate was very higher in the initial five days of hospitalization with critical care support. Our result findings provide clinical inferences for physicians to identify high-risk factors with COVID-19 at a very early stage.

Abstract Work in other species has demonstrated an impact of gestational exposure on flavor preferences. Although equine palatability preferences in mature horses have been identified, feeding behaviors in growing horses are not well documented. The objective of this study was to evaluate the impact of exposure to common palatants in utero on feeding preferences of weanlings. Stock-type weanlings (n = 4) weighing 225(±18.15) kg at 29(±2.55) weeks of age were used in a side-by-side comparison test with a divided feeding platform. Common palatants (apple and anise) were utilized throughout the broodmare gestational period. A novel palatant, peppermint, was withheld during gestation to identify impacts associated with neophobic tendencies. Treatments were offered once daily for three consecutive days across three periods (4 weeks apart) using a pelleted concentrate feed with an application rate of 0.375 mL/0.23 kg. Weanlings were allowed free access to the feeding platform with identical pans spaced 6” apart for 20 minutes. Treatment location within the feeding platform was changed daily to limit effects associated with side-eating. Data were measured as a Chi Square test of SAS using PROC FREQ statement with α ≤. 0.05. Despite gestational exposure to apple and anise, no preference was measured in palatability assessments including First Sniff (P = 0.29), First Consumed (P = 0.70), First Finished (P = 0.29). These data suggest that exposure in utero failed to elicit a preference for common palatants in weanling horses. Additionally, these data fail to demonstrate a neophobic effect for a novel palatant, peppermint.

Introduction: The impact of beta blocker use on surgical outcomes of cancer patients receiving immunotherapy is unknown. Hypothesis: Beta blocker use is associated with lower post-operative mortality in cancer patients on immunotherapy. Methods: We used an institutional Advanced Cohort Explorer to identify all patients who underwent any surgical procedure less than 90 days after receiving immunotherapy. Data on the procedure performed as well as the post-operative outcome were collected and analyzed per the pre-operative beta blocker use status. Results: A total of 233 patients underwent surgery between 09/2011-06/2019. Mean age was 64.7 years (range: 16-92). The most common cancer diagnoses were lung (48, 44.4%), melanoma (49, 45.4%) and kidney (11, 10.2%). Immunotherapy medications were pembrolizumab ( 127, 54.5%), nivolumab (51, 21.9%), ipilimumab (43, 18.5%), atezolizumab (11, 4.7%) and avelumab (1, 0.43%). Pre-operative beta blocker use was documented in 140 (60.1%) patients. Most common surgical procedures were skin resection (75, 32.1%), wound repair (47, 20.2%), vascular procedures (36, 15.5%), urethral procedures 16 (6.9%) and sentinel lymph node biopsies (10, 4.3%). The 30-day mortality rate was 10.3% (24 deaths). In a multi-variable logistic regression analysis, pre-operative use of beta blockers was associated with a lower risk of death within 30 days from surgery (OR 0.34, CI 0.13-0.87, P=0.024). 30-day mortality rates were higher in patients undergoing vascular (50%, 17 of 34) versus non-vascular (3.5%, 7 of 199) procedures (P<0.0001) in a Chi Square test. Conclusions: Beta blocker use is associated with a lower 30-day mortality rate after surgical procedures in cancer patients treated with immunotherapy. Further investigation is warranted.
