AbstractThis paper empirically examines the economic effects of COVID-19 vaccine rollouts using a cross-country daily database of vaccinations and high-frequency indicators of economic activity—nitrogen dioxide (NO2) emissions, carbon monoxide (CO) emissions, and Google mobility indices—for a sample of 46 countries over the period December 16, 2020 to June 20, 2021. Using surprises in vaccines administered, we find that an unexpected increase in vaccination per capita is associated with a significant increase in economic activity. We also find evidence for nonlinear effects of vaccines, with the marginal economic benefits being larger when vaccination rates are higher. Country-specific conditions play an important role, with lower economic gains if strict containment measures are in place or if the country is experiencing a severe outbreak. Finally, the results provide evidence of spillovers across borders, highlighting the importance of equitable access to vaccines across nations.

Infectious coryza is an acute infectious respiratory disease in chickens that is caused by Avibacterium paragallinarum (A. paragallinarum). Infectious coryza has major economic effects due to decreased egg production in growing birds and slowed growth in broilers. In this study, we isolated and identified 40 strains of A. paragallinarum from chickens that showed typical clinical signs of coryza in part of China from 2019 to 2020. Using a hemagglutination-inhibition test, 11 isolates were identified as serovar A, 10 isolates were identified as serovar B, and 19 isolates were identified as serovar C. Antimicrobial sensitivity tests showed that high minimum inhibitory concentration (MIC) values were encountered for compounds sulfamethoxine sodium and oxytetracycline hydrochloride. Especially, of the 40 A. paragallinarum isolates, 30% had an MIC value of compound sulfamethoxine sodium of 64 μg/mL, 10% of 128 μg/mL, and 15% of 256 μg/mL. For oxytetracycline hydrochloride, 85% of isolates showed MIC values of 64 μg/mL or more. Excitingly, the MIC values of β-lactamase (amoxicillin, ampicillin, and ceftiofur) were low, with 77.5%, 70%, and 92.5% of isolates having an MIC value of ≤1 μg/mL, respectively. Our results may provide a reference for the treatment of infectious coryza.

The analysis of the effects that free trade has within the context of the Philippines and its fellow co-members within the Association of Southeast Asian Nations was purposed as a conduit for greater insight on trade relations between the nations of what is being considered as a fast-growing unified economy. In a more specific lens, the paper identifies how the Philippines and its fellow nations within the bloc conduct free trade while also carefully examining the number of goods that are being imported and exported. The study will use a Quantitative research design to find the changes in exports and imports as well as to point out the association between the dependent and independent variables. The study also determines the effect of trade policy. The research is a cross-country study exclusive to ASEAN-6, namely Brunei, Indonesia, Malaysia, Singapore, Thailand and the Philippines, and the period of the study is from the year 1993 – 2015. The researchers used Ordinary Least Squares and showed a high degree of predictability between the dependent and independent variables. The findings confirm that there exists a significant degree of negative correlation between the import and inflation, tariff and FDI. On the other hand, there is a significant positive correlation between the FDI and import of 4 ASEAN countries, namely Brunei, Singapore, Thailand, and Indonesia, besides a negative correlation between FDI and import of Malaysia. While the tariff and inflation of the Philippines and imports come up with a negative relationship, so this brings us to the conclusion that the independent variables are affected by the policy of free trade but for the good of the economies of the countries involved. With the result of the study, it is expected that further examination of this topic will expound more as the zeitgeist affecting the ASEAN bloc continues to tentatively change. The policy-makers should build an inclusive and sustainable trading system by identifying priorities for improvement and clarifying the design of new trade rules. The policy-makers should also come up with indicators, trade facilitation performance of different countries, information on the level of trade in services restrictiveness, and also records on export restrictions.

Abstract Heat stress (HS) mitigation strategies are critically needed to combat the substantial economic effects on animal agriculture. The manifestations of seasonal infertility include delayed puberty onset, reduced conception rates, decreased litter size, and increased wean to estrus interval. To assess the effects of HS during early gestation and evaluate a benefit of supplemental altrenogest (ALT) as a mitigation strategy, thirty crossbred post-pubertal gilts (157 ± 11 kg) were subjected to estrous synchronization via 14 d oral administration of ALT. Artificial insemination during estrus was performed and gilts were then placed into one of four treatment groups; heat stress (HS; 35 ± 1 οC for 12h/31.60 ± 1 οC for 12h) with (HSALT, n = 7) or without (HSCON, n = 7) 15 mg/d ALT supplementation or thermal neutral (TN; 20 ± 1 οC) conditions with (TNALT, n = 8) or without (TNCON, n = 8) 15 mg/d ALT supplementation until 12 d post-estrus (dpe). Administrating ALT occurred at 0600 h from 3-12 dpe and rectal temperatures (TR) and respiration rates (RR) were recorded. Blood was collected via jugular venipuncture on 0, 4, 8 and 12 dpe. Gilts were euthanized humanely at 12 dpe followed by collection of ovarian tissue, and uterine flushing for conceptus collection. In HS compared to TN gilts, RR and TR were increased (P < 0.01) but unaffected by ALT supplementation. Feed intake (FI) was reduced (P < 0.01) by HS but unaltered by ALT treatment. Corpora lutea (CL) weight was reduced (P < 0.01) in HSCON gilts when compared to TNCON and HSALT gilts despite progesterone (P4) concentrations in serum and luteal tissue not being affected by treatment (P ≥ 0.10). CL diameter was reduced (P ≤ 0.05) in HSALT gilts compared to other treatments. Interleukin-1β (IL1B) uterine flush concentration was not affected (P > 0.20) by environment or ALT supplementation, although moderate (P = 0.06) interaction between environment and ALT existed, as IL1B concentration in TNALT was increased (P = 0.03) compared to TNCON gilts. While environment did not affect conceptus development (P = 0.90), ALT supplementation advanced conceptus elongation (P < 0.01). Collectively, these data demonstrate that HS may affect luteal development prior to pregnancy establishment, and ALT increases conceptus elongation by12 dpe.

We consider risk sharing among individuals in a one-period setting under uncertainty that will result in payoffs to be shared among the members. We start with optimal risk sharing in an Arrow–Debreu economy, or equivalently, in a Borch-style reinsurance market. From the results of this model we can infer how risk is optimally distributed between individuals according to their preferences and initial endowments, under some idealized conditions. A main message in this theory is the mutuality principle, of interest related to the economic effects of pandemics. From this we point out some elements of a more general theory of syndicates, where in addition, a group of people are to make a common decision under uncertainty. We extend to a competitive market as a special case of such a syndicate.


Significance This has implications for the size of the workforce and the living standards that the US economy is capable of supporting. It will also have broader consequences for the US economy over the next 30 years. Impacts Lower workforce participation rates will lower average living standards, relative to what they would have otherwise been, by 10% by 2050. Medicare and social security spending will rise by 4% of GDP over the next 30 years; higher taxes or spending cuts elsewhere will be needed. Immigration is projected to be just sufficient to offset natural population decline by 2050, cushioning the working-age population drop. Estimating the extent to which immigration and automation could help to fill worker shortages over the longer term is difficult.

Background: Drug utilization Evaluation is the main tool to assess the clinical and economic effects of drug on health-care system. The aim of the current study is to evaluate the regimens of antibiotic prophylaxis in common gynecological surgeries in a referral teaching hospital Methods: This cross-sectional study was done in Alzahra hospital, Tabriz, Iran, from July 2017 to December 2017. Patients who received antibiotics as surgical site infection prophylaxis were enrolled. Data were collected from patients’ medical records and adherence rate to the American Society of Health-System Pharmacists (ASHP) guideline was studied as the primary endpoint. Results: A total of 210 patients who undergoes common gynecological surgeries were evaluated. Cesarean section (58.6%) and total abdominal hysterectomy (28.1%) were the majority of surgeries. The type of administered antibiotic was adherent to guideline in 71.4%. Doses and duration of prescribed antibiotic (Cefazolin, the most prescribed antibiotic) were not in accordance with the guideline in 100%. Only in 58%, the time of antibiotic administration was corrected. Conclusion: In this study, the misuse of antibiotics in most cases was documented in terms of type, dose and duration of drug administration in Al-Zahra Hospital. It seems necessary to publish evidence-based guidelines and monitor their proper implementation, not only to reduce costs but also to combat antibiotic resistance.

Background Since the start of the COVID-19 pandemic, less acute care surgical procedures have been performed and consequently hospitals have experienced significant revenue loss. We aim to investigate these procedures performed before and after the start of the COVID-19 pandemic, as well as their effect on the economy. Methods This is a retrospective analysis of patients who underwent cholecystectomies and appendectomies during March–May 2019 compared to the same time period in 2020 using Chi-square and t-tests. Results There were 345 patients who presented with appendicitis or cholecystitis to Elmhurst Hospital Center during the March–May 2019 and 2020 time period. There were three times as many total operations, or about 75%, in 2019 (261) compared to 2020 (84). There was a decrease in the number of admissions from 2019 to 2020 for both acute cholecystitis (149 vs 43, respectively) and acute appendicitis (112 vs 41, respectively). The largest decrease in the number of admissions in 2020 compared to 2019 was observed in April 2020 (98 vs 9, P < .01) followed by May [69 vs 20, P < .01], and March [94 vs 55, P < .01]. Corresponding to the decrease in operative patterns was a noticeable six-time reduction in revenue for the procedures in 2019 ($187,283) compared to 2020 ($30,415). Conclusion We observed almost a triple reduction in the number of cholecystitis and appendicitis procedures performed during the 2020 pandemic surge as compared to the 2019 pre-pandemic data. Elmhurst hospital also experienced four times the loss of revenue during the same time period.
