Background As the disease caused by the novel coronavirus has spread globally, there has been significant economic instability in the healthcare systems. This reality was especially accentuated in Ecuador where, the shortage of healthcare workers combined with cultural and macroeconomic factors has led Ecuador to face the most aggressive outbreak in Latin America. In this context, the participation of final-year medical students on the front line is indispensable. Appropriate training on COVID-19 is an urgent requirement that universities and health systems must guarantee. We aimed to describe the knowledge, attitudes, and practices of Ecuadorian final-year medical students that could potentially guide the design of better medical education curricula regarding COVID-19. Methods This was a cross-sectional 33-item online survey conducted between April 6 to April 2020 assessing the knowledge, attitudes, and practices toward the diagnosis, treatment, prevention, and prognosis toward COVID-19 in Ecuadorian final-year medical students. It was sent by email, Facebook, and WhatsApp. Results A total of 309 students responded to the survey. Out of which 88% of students scored high (≥ 70% correct) for knowledge of the disease. The majority of students were pessimistic about possible government actions, which is reflected in the negative attitude towards the control of COVID-19 and volunteering during the outbreak in Ecuador (77%, and 58% of the students, respectively). Moreover, 91% of students said they did not have adequate protective equipment. The latter finding was significantly associated with negative attitudes. Conclusions Although a large number of students displayed negative attitudes, the non-depreciable percentage of students who were willing to volunteer and the coexisting high level of knowledge displayed by students, suggests that Ecuador has a capable upcoming workforce that could benefit from an opportunity to strengthen, improve and advance their training in preparation for COVID-19. Not having personal protective equipment was significantly associated to negative attitudes. Providing the necessary tools and creating a national curriculum may be one of the most effective ways to ensure all students are trained, whilst simultaneously focusing on the students’ most pressing concerns. With this additional training, negative attitudes will improve and students will be better qualified.

Purpose Understanding the method of thyroid cancer detection has potential implications on interpreting incidence rates, the diagnosis and management of thyroid cancer. We conducted a systematic review of studies reporting methods of thyroid cancer detection to estimate the frequency of incidentally found cancers and classify triggers of incidental thyroid cancer diagnosis. Methods We searched multiple bibliographic databases from inception to June 2020. A pair of reviewers, working independently and in duplicate selected studies for inclusion, extracted data, and evaluated each trial's risk of bias. Studies enrolling patients older than 18 years with thyroid cancer confirmed histologically were included. Results In total, 17 cohorts and 1 cross-sectional study, conducted between 1991 and 2018, enrolling 4668 patients with thyroid cancer were included: 88% had papillary thyroid cancer and 23% had papillary thyroid microcarcinoma. The proportion of patients with non-incidental and incidental thyroid cancer was similar: 49% [95% confidence interval (CI): 40-58%]. Subgroup analysis showed that most patients with incidental thyroid cancers had tumor size <10 mm (76%; 95% CI: 56-92%), age >45 (61%; 95% CI: 56-67%), and were detected through imaging (35%; 95% CI: 26-45%), of which ultrasound was the most common modality (27%; 95% CI: 14-43%). The heterogeneity for all the effect sizes was large and significant. Conclusions About half of thyroid cancers were found incidentally through the use of imaging studies, in particular neck ultrasound. These incidentally found cancers were mostly small papillary thyroid cancer. These results highlight opportunities for interventions aimed at reducing drivers of overdiagnosis.

Purpose Nearly half the cases of thyroid cancer, a malignancy rapidly rising in incidence within the United States, are attributable to small and asymptomatic papillary thyroid cancers that will not increase mortality. A primary driver of thyroid cancer overdiagnosis is ultrasound use. It is therefore valuable to understand how inappropriate use of thyroid ultrasound is defined, analyze the current evidence for its frequency, and identify interventions to lessen misuse. Methods Ovid MEDLINE(R), Ovid EMBASE, and Scopus databases were searched from inception to June 2020 for studies assessing inappropriate use of thyroid ultrasound. Reviewers, working independently and in duplicate, evaluated studies for inclusion, extracted data, and graded risk of bias. We used a random-effects model with a generalized linear mixed approach to calculate the mean overall proportion estimates of inappropriate use. Results Seven studies (total n = 1573) met the inclusion criteria with moderate to high risk of bias. Inappropriate thyroid ultrasound use was described variably, using published practice guidelines, third-party expert reviewers, or author interpretations of the literature. The overall frequency of inappropriate thyroid ultrasound use was 46% (95% CI 15-82%; n = 388) and 34% (95% CI 16-57%; n = 190) among studies using guideline based definitions. The pooled frequency of iUS due to thyroid dysfunction (either hypothyroidism or thyrotoxicosis) was 17% (95% CI 7-37%; n = 191) and the frequency of iUS due to nonspecific symptoms without a palpable mass was 11% (95% CI 5-22%; n = 124). No study examined interventions to address inappropriate use. Conclusions Low quality evidence suggests that inappropriate use of thyroid ultrasound is common. Interventional studies aiming to decrease the inappropriate use of thyroid ultrasound are urgently needed.

PURPOSE Access to health care is a long-standing concern for rural patients; however, administrative measures fail to capture the subjective patient experience of accessing health care. The purpose of this review was to synthesize the qualitative literature on patient and caregiver experiences of accessing health care services for chronic disease management among US residents of rural areas. METHODSWe searched Embase, MEDLINE, PsycInfo, CINAHL, and Scopus to identify qualitative studies published during 2010-2019. A thematic synthesis approach was used to analyze findings from included studies. RESULTS A total of 62 studies involving 1,354 unique participants were included. The largest share of studies (24.2%) was focused on the experience of patients with cancer, followed by behavioral health (16.1%), HIV and AIDS (14.5%), and diabetes (12.9%). We identified 4 primary analytic themes of barriers and facilitators associated with the experience of accessing health care services for chronic disease management in rural areas: (1) navigating the rural environment, (2) navigating the health care system, (3) financing chronic disease management, and (4) rural life (ie, common elements of a distinct "rural" way of thinking and behaving).CONCLUSIONS In this comprehensive review, we found that important cultural, structural, and individual factors influenced the rural patient's experience of health care access and use, including barriers and facilitators posed by geographic and built environments, and distinct rural mores. Our findings can inform policies and programs that both facilitate structural aspects of access and include culturally appropriate interventions.

Objectives:To determine whether the available operative techniques for thymectomy in myasthenia gravis (MG) confer variable chances for achieving complete stable remission (CSR), we performed a meta-analysis of comparative studies of surgical approaches to thymectomy.Methods:Meta-analysis of all studies providing comparative data on thymectomy approaches, with CSR reported and minimum 3 years mean follow-up.Results:12 cohort studies and one randomized clinical trial, containing 1598 patients, met entry criteria. At 3 years, CSR from MG was similar following VATS extended vs. both basic (RR 1.00, p=1.00, 95% CI 0.39-2.58) and extended (RR 0.96, p=0.74, CI: 0.72-1.27) transsternal approaches. CSR at 3 years was also similar following extended transsternal vs. combined transcervical-subxiphoid (RR 1.08, p=0.62, CI: 0.8-1.44) approaches. VATS extended approaches remained statistically equivalent to extended transsternal approaches through 9 years of follow-up (RR 1.51, p=0.05, CI: 0.99-2.30). The only significant difference in CSR rate between a traditional open and a minimally invasive approach was seen at 10 years when comparing the now-abandoned basic (non-sternum-lifting) transcervical approach and the extended transsternal approach (RR 0.4, p=0.01, CI: 0.2-0.8).Conclusions:A significant difference in the rate of CSR among various surgical approaches for thymectomy in MG was identified only at long-term follow-up, and only between what might be considered the most aggressive approach (extended transsternal thymectomy) and the least aggressive approach (basic transcervical thymectomy). Extended minimally invasive approaches appear to have equivalent CSR rates to extended transsternal approaches and are therefore appropriate in the hands of experienced surgeons.

The introduction of robotics in living donor liver transplantation has been revolutionary. We aimed to examine the safety of robotic living donor right hepatectomy (RLDRH) compared to open (ODRH) and laparoscopic (LADRH) approaches. A systematic review was carried out in Medline and six additional databases following PRISMA guidelines. Data on morbidity, postoperative liver function, and pain in donors and recipients were extracted from studies comparing RLDRH, ODRH, and LADRH published up to September 2020; PROSPERO (CRD42020214313). Dichotomous variables were pooled as risk ratios and continuous variables as weighted mean differences. Four studies with a total of 517 patients were included. In living donors, the postoperative total bilirubin level (MD: −0.7 95%CI −1.0, −0.4), length of hospital stay (MD: −0.8 95%CI −1.4, −0.3), Clavien–Dindo complications I–II (RR: 0.5 95%CI 0.2, 0.9), and pain score at day > 3 (MD: −0.6 95%CI −1.6, 0.4) were lower following RLDRH compared to ODRH. Furthermore, the pain score at day > 3 (MD: −0.4 95%CI −0.8, −0.09) was lower after RLDRH when compared to LADRH. In recipients, the postoperative AST level was lower (MD: −0.5 95%CI −0.9, −0.1) following RLDRH compared to ODRH. Moreover, the length of stay (MD: −6.4 95%CI −11.3, −1.5) was lower after RLDRH when compared to LADRH. In summary, we identified low- to unclear-quality evidence that RLDRH seems to be safe and feasible for adult living donor liver transplantation compared to the conventional approaches. No postoperative deaths were reported.

The COVID-19 pandemic has put a lot of pressure on health systems worldwide. Mass vaccination against SARS-CoV-2 has reduced morbidity and mortality worldwide. Despite their safety profiles, vaccines, as with any other medical product, can cause adverse events. Yet, in countries with poor epidemiological surveillance and monitoring systems, reporting vaccine-related adverse events is a challenge. The objective of this study was to describe self-reported vaccine adverse events after receiving one of the available COVID-19 vaccine schemes in Ecuador. A cross-sectional analysis based on an online, self-reported, 32-item questionnaire was conducted in Ecuador from 1 April to 15 July 2021. Participants were invited by social media, radio, and TV to voluntarily participate in our study. A total of 6654 participants were included in this study. Furthermore, 38.2% of the participants reported having at least one comorbidity. Patients received AstraZeneca, Pfizer, and Sinovac vaccines, and these were distributed 38.4%, 31.1%, and 30.5%, respectively. Overall, pain or swelling at the injection site 17.2% (n = 4500) and headache 13.3% (n = 3502) were the most reported adverse events. Women addressed events supposedly attributable to vaccination or immunization [ESAVIs] (66.7%), more often than men (33.2%). After receiving the first dose of any available COVID-19 vaccine, a total of 19,501 self-reported ESAVIs were informed (87.0% were mild, 11.5% moderate, and 1.5% severe). In terms of the vaccine type and brand, the most reactogenic vaccine was AstraZeneca with 57.8%, followed by Pfizer (24.9%) and Sinovac (17.3%). After the second dose, 6776 self-reported ESAVIs were reported (87.1% mild, 10.9% moderate, and 2.1% severe). AstraZeneca vaccine users reported a higher proportion of ESAVIs (72.2%) in comparison to Pfizer/BioNTech (15.9%) and Sinovac Vaccine (11.9%). Swelling at the injection site, headache, muscle pain, and fatigue were the most common ESAVIs for the first as well as second doses. In conclusion, most ESAVIs were mild. AstraZeneca users were more likely to report adverse events. Participants without a history of COVID-19 infection, as well as those who received the first dose, were more prone to report ESAVIs.
