Abstract
INTRODUCTION Recent studies revealed that coronavirus disease 2019 (COVID-19) negatively impacted residency programs worldwide, particularly procedure-based programs. However, most studies are from high-income countries, with scarce data from low- and middle-income countries. Pandemic effects on surgical training were likely worse in strictly apprenticeship models relying heavily on surgical volume as opposed to competency-based programs. Notably, training programs in Brazil and other low- and middle-income countries follow these strict apprenticeship style frameworks. In this study, we aimed to evaluate the trainees' perceptions of the impact of COVID-19 on their Brazilian surgical programs. METHODS A cross-sectional study was performed using an anonymous survey in Portuguese, distributed via social media platforms to surgical residents enrolled in Brazilian surgery programs. Data collection took place from August 2021 to May 2022. The survey contained 30 questions on the perception of the impact of COVID-19 on surgical training. RESULTS One-hundred sixty-two residents from 17 different surgical specialties and all five regions of Brazil responded to the survey. Of 162 residents, 145 (89%) believed the pandemic negatively impacted their surgical training. Furthermore, of 162 residents, 153 (94%) reported that elective surgical volume decreased during the pandemic and 91 (56%) were redeployed to assist with COVID-19 management. As a result, 102 of 162 (63%) residents believed their surgical skills were negatively impacted by COVID-19. Yet, 95 of 162 (59%) residents reported their residency programs did not offer resources to mitigate the pandemic's impact on training. Of 162 residents, 57 (35%) reported they did not feel on track for graduation, with no statistical difference between responses by year of residency (P = 0.083). Additionally, 124 of 162 (77%) residents reported that the pandemic negatively affected their mental health, most commonly related to stress at work, stress about transmitting COVID-19, and loss in surgical training. CONCLUSIONS Most of the surveyed Brazilian surgical residents felt the COVID-19 pandemic negatively impacted their training. This leads to believe that the detrimental impacts of the pandemic exposed preexisting weaknesses in the Brazilian surgical training model's dependence on a strict apprenticeship model. Our findings suggest a crucial need to redesign surgical education programs to make residency programs more prepared for changes in surgical volume, evolve the apprenticeship model to competency-based approaches, and unify surgical training standards in low- and middle-income countries.

Abstract
1. The aim of the present study was to evaluate the effect of preventive and curative isosorbide-5-mononitrate (Is-5-Mn) treatment on the development of hypertension, cGMP content, thromboxane (TX) A(2)/prostaglandin (PG) I2 balance, the peripheral serotonergic system, platelet activation, lipid peroxidation and plasma lipids in cyclosporine A (CsA)-induced hypertensive rats. 2. Control, CsA (5 mg/kg per day) and Is-5-Mn (150 mg/kg per day, b.i.d.) rat groups were treated orally over a period of 7 weeks. The preventive Is-5-Mn group (Is-5-Mn + CsA) was first treated for 2 weeks with Is-5-Mn, followed by 7 weeks with both drugs; the curative Is-5-Mn group (CsA + Is-5-Mn) was treated for a period of 7 weeks with CsA and with both drugs for an additional 5 weeks. The control group received oral vehicle. 3. Whereas in the group undergoing preventive treatment the CsA-induced increase in blood pressure (BP), compared with the control group, was avoided, in the group undergoing curative treatment, the increase in BP was even higher. The decreased arterial cGMP content in the CsA group was prevented and reverted when Is-Mn was administered either preventatively or curatively with CsA. Platelet TXA2 production, although unaffected in the Is-5-Mn + CsA group, was significantly higher in the CsA + Is-5-Mn group compared with the group receiving CsA alone. Furthermore, plasma TXA2 was reduced following preventive Is-5-Mn treatment, but was worsened in the group undergoing curative therapy. Aortic PGI2 synthesis was identical in all groups. Consequently, the TXA2/PGI2 ratio was only altered in the CsA + Is-5-Mn group, demonstrating a markedly higher value. In both groups treated simultaneously with CsA and Is-5-Mn, a higher platelet 5-hydroxytryptamine (5-HT) content was obtained compared with CsA treatment alone, but only preventive treatment with Is-5-Mn resulted in a significant reduction in plasma 5-HT. Changes in ADP and collagen-induced platelet aggregation paralleled those of plasma 5-HT and TXA2: the hyperaggregation profile of the CsA group, although partially prevented, was not reverted by simultaneous treatment with Is-5-Mn and CsA. Lipid peroxidation and lipid profile values also worsened in the CsA + Is-5-Mn group compared with the group administered CsA alone. 4. In conclusion, the beneficial effects of concomitant Is-5-Mn and CsA treatment were demonstrated when Is-5-Mn was administered preventatively because not only was arterial hypertension prevented, but platelet aggregation and plasma TXA2 and 5-HT levels were also reduced. In contrast, following curative treatment, the BP, platelet/vascular vasoconstrictor balance, lipid peroxidation and plasma lipids were aggravated, recommending a judicious evaluation of the impact of nitrate therapy throughout the period of its administration.

Abstract
It is currently under debate whether the pathogenesis of end-stage renal failure in non-insulin-dependent diabetes mellitus (NIDDM) is a consequence of microangiopathy alone. The aim of this study was to investigate intrarenal arteriosclerosis and its correlation with kidney function in NIDDM. In 36 diabetic subjects, and in 10 age- and sex-matched healthy control subjects we measured kidney volume and resistive index of the interlobar arteries by duplex Doppler ultrasonography. Clinical and metabolic parameters, renal function and vascular sequelae of the disease were also evaluated. In diabetic subjects resistive index (median 0.72, range 0.54-0.79) was higher than in control subjects (median 0.62, range 0.57-0.66) (2p < 0.002). Kidney volume and resistive index correlated with age (p < 0.004), body mass index (p < 0.001), mean blood pressure (p < 0.001), total and LDL cholesterol (p < 0.01) and creatinine clearance (p < 0.001 and < 0.01, respectively). Kidney volume also correlated with HbA1 (p < 0.01) and resistive index with uric acid (p < 0.01). Lower body macroangiopathy was associated with increased resistive index and reduced kidney volume (2p < 0.05), while upper body macroangiopathy and microangiopathy were not. Our data suggest that macroangiopathy rather than microangiopathy is mainly responsible for impairment of kidney function in NIDDM. The resistive index of interlobar arteries seems to be a reliable marker of intrarenal arteriosclerosis and can be used as a non-invasive, easily available parameter of its evolution.

Abstract
During meiosis, axial elements are generated by the condensation of sister chromatids along a protein core as precursors to the formation of the synaptonemal complex (SC). Functional axial elements are essential for wild-type levels of recombination and proper reductional segregation at meiosis I. Genetic and cytological data suggest that three meiosis-specific genes, HOP1, RED1 and MEK1, are involved in axial element formation in the yeast Saccharomyces cerevisiae. HOP1 and RED1 encode structural components of axial elements while MEK1 encodes a putative protein kinase. Using a partially functional allele of MEK1, new genetic interactions have been found between HOP1, RED1 and MEK1. Overexpression of HOP1 partially suppresses the spore inviability and recombination defects of mek1-974; in contrast, overexpression of RED1 exacerbates the mek1-974 spore inviability. Co-overexpression of HOP1 and RED1 in mek1-974 diploids alleviates the negative effect of overexpressing RED1 alone. Red1p/Red1p as well as Hop1p/Red1p interactions have been reconstituted in two hybrid experiments. Our results suggest a model whereby Mek1 kinase activity controls axial element assembly by regulating the affinity with which Hop1p and Red1p interact with each other.

Abstract
Using a screen designed to identify yeast mutants specifically defective in recombination between homologous chromosomes during meiosis, we have obtained new alleles of the meiosis-specific genes, HOP1, RED1, and MEK1. In addition, the screen identified a novel gene designated MSH5 (MutS Homolog 5). Although Msh5p exhibits strong homology to the MutS family of proteins, it is not involved in DNA mismatch repair. Diploids lacking the MSH5 gene display decreased levels of spore viability, increased levels of meiosis I chromosome nondisjuction, and decreased levels of reciprocal exchange between, but not within, homologs. Gene conversion is not reduced. Msh5 mutants are phenotypically similar to mutants in the meiosis-specific gene MSH4 (Ross-Macdonald and Roeder 1994). Double mutant analysis using msh4 msh5 diploids demonstrates that the two genes are in the same epistasis group and therefore are likely to function in a similar process--namely, the facilitation of interhomolog crossovers during meiosis.

Abstract
To evaluate the merits of laparoscopic inguinal hernia repair (LHR) compared to conventional open hernia repair (OHR) a randomized study has been conducted. All patients were day surgical cases, of which 44 were randomized to a standardized OHR under local anesthetic (LA) and 42 to an LHR under general anesthesia (GA). Fifteen LHR patients had bilateral repairs. Operative time for OHR was 30.5 min, for unilateral LHR 35 min, and for bilateral LHR 60 min. OHR patients were discharged after a median of 134.5 min, which was significantly shorter than LHR patients, whose median discharge was 225 min (P < 0.01). Pain scores, activity levels, analgesia requirements, and time taken to return to work were not significantly different following surgery in either group (P < 0.05). There have been two recurrent hernias and one small bowel obstruction in the LHR group. We conclude that both repairs can be successfully performed as day surgical procedures. The added cost of LHR at this stage does not warrant its widespread use in unilateral hernia repairs. Which procedure is adopted should be individualized; however, patients with bilateral hernias on presentation can be successfully managed as day cases, obviating the need for hospitalization or two operations.
