A review of severe acute respiratory syndrome - coronavirus 2
The pandemic caused by SARS-CoV-2 in 2020 and still raging in 2021 is a global emergency where no country was spared from its high morbidity and mortality. Life changed in innumerable ways, from lock downs to job losses, isolation and mental health crisis. All countries suffered. If it were not for the quick development of medications and vaccines, coupled with preventive measures like facial masks, social distancing and frequent washing of hands, we will be in a worse chaos. Some countries like India and many in Latin America have been devastated and its consequences will be long felt even after the pandemic is controlled. Understanding the cause, its epidemiology and controlled measures is important. Although it took 100 years to encounter a global pandemic of this magnitude, scientists warn of almost inevitable future global pandemics. This review will explore some salient aspects of SARS-CoV-2 impact and measures to control the infection. The world’s death toll caused by SARS-CoV-2 exceeds 3 million and close to 200 million people have been infected. The available vaccines used in more than 400 million individuals, still fall short of producing herd immunity despite the high efficacy rate of most of them. There is a pressing need to immunize 80% or more. Some side effects to vaccine were reported, the majority of minor impact, although some rare ones are more serious such as thrombotic thrombocytopenia or myocarditis. Still the protection afforded from the vaccine vastly outweighs the risks and its wide use is encouraged.The pandemic caused by SARS-CoV-2 in 2020 and still raging in 2021 is a global emergency where no country was spared from its high morbidity and mortality.

Importancia de la acreditacion internacional de facultades de medicina
As of 2024, medical school graduates who wish to pursue graduate studies in the U.S. or in Canada, they must have graduated from medical schools with quality educational programs endorsed by recognized agencies, capable of granting international accreditation. The World Federation for Medical Education (WFME) is one of these agencies. The WFME accepted the new accreditation policy of the Educational Committee for Foreign Medical Education (ECFMG) whereby physicians applying for ECFMG certification from 2024 onwards, must have graduated from a university medical center accredited by a quality assurance agency that is recognized by the WFME. The COMAEM (Mexican Council for the Accreditation of Medical Education) is endorsed by the WFME and other international organizations that ensure the quality of higher education. The accreditation granted by COMAEM is a recognition that the medical program meets the criteria, indicators and quality parameters established by this organization. Starting in 2024, graduates of an accredited program will be able to apply for ECFMG certification through the United States Medical Licensing Examination (USMLE) and thus be able to do a specialty residency or work in the U.S. In Peru, only the Alberto Hurtado School of Medicine of the Cayetano Heredia Peruvian University has completed the international accreditation process through COMAEM and has received such accreditation.A partir de 2024, egresados de facultades de medicina que deseen hacer estudios de postgrado en los EE.UU o el Canadá, deberán graduarse en escuelas de medicina con programas educativos de calidad avalados por agencias reconocidas capaces de otorgar una acreditación internacional.

A partir de 2024, los egresados de un programa acreditado podrán postular para la certificación del ECFMG a través del examen de licencia médica de los Estados Unidos o USMLE (United States Medical Licensing Examination) y asà poder hacer una residencia de especialización o trabajar en EE. UU. En el Perú, solo la Facultad de Medicina Alberto Hurtado de la Universidad Peruana Cayetano Heredia ha completado el proceso de acreditación internacional a través de COMAEM y ha recibido dicha acreditación
El impacto de la pandemia del COVID-19 en la educación médica: adaptabilidad y experiencia con enseñanza a distancia de la Sociedad Médica Peruano Americana
The COVID-19 pandemic had a significant impact on medical care and medical education in Peru. In response, the Peruvian American Medical Society (PAMS), a charitable medical organization based in the USA, pursued its medical and educational missions in Peru by adopting virtual learning technology. We developed closer collaborative relationships with several medical schools and the Peruvian Association of Medical Schools (ASPEFAM) while offering a faculty panel of twenty-four members to provide lectures and multidisciplinary webinars in Spanish. We conducted 19 webinars including COVID -19 and non-COVID-19 related topics that over the last two years attracted 14,489 participants from 23 countries. They were the foundation for twenty publications in Peruvian medical journals. Our clinical investigations competition was positively received as was our pilot project on research mentorship. The COVID -19 pandemic had a positive effect on the educational mission of PAMS in Peru.La pandemia del COVID-19 tuvo un impacto significativo en el cuidado y la educación médicos en el Perú.

In
urban environments, airborne particles are continuously emitted,
followed by atmospheric aging. Also, particles emitted elsewhere,
transported by winds, contribute to the urban aerosol. We studied
the effective density (mass-mobility relationship) and mixing state
with respect to the density of particles in central Copenhagen, in
wintertime. The results are related to particle origin, morphology,
and aging. Using a differential mobility analyzer-aerosol particle
mass analyzer (DMA-APM), we determined that particles in the diameter
range of 50–400 nm were of two groups: porous soot aggregates
and more dense particles. Both groups were present at each size in
varying proportions. Two types of temporal variability in the relative
number fraction of the two groups were found: soot correlated with
intense traffic in a diel pattern and dense particles increased during
episodes with long-range transport from polluted continental areas.
The effective density of each group was relatively stable over time,
especially of the soot aggregates, which had effective densities similar
to those observed in laboratory studies of fresh diesel exhaust emissions.
When heated to 300 °C, the soot aggregate volatile mass fraction
was ∼10%. For the dense particles, the volatile mass fraction
varied from ∼80% to nearly 100%
Gene x dietary pattern interactions in obesity : analysis of up to 68 317 adults of European ancestry
Obesity is highly heritable. Genetic variants showing robust associationswith obesity traits have been identified through genome wide association studies. We investigated whether a composite score representing healthy diet modifies associations of these variants with obesity traits. Totally, 32 body mass index (BMI)- and 14 waist-hip ratio (WHR)-associated single nucleotide polymorphismswere genotyped, and genetic risk scores (GRS) were calculated in 18 cohorts of European ancestry (n = 68 317). Diet score was calculated based on self-reported intakes of whole grains, fish, fruits, vegetables, nuts/seeds (favorable) and red/processed meats, sweets, sugar-sweetened beverages and fried potatoes (unfavorable). Multivariable adjusted, linear regression within each cohort followed by inverse variance-weighted, fixed-effects meta-analysis was used to characterize: (a) associations of each GRS with BMI and BMI-adjustedWHR and (b) diet score modification of genetic associations with BMI and BMI-adjusted WHR. Nominally significant interactions (P = 0.006-0.04) were observed between the diet score and WHR-GRS (but not BMI-GRS), two WHR loci (GRB14 rs10195252; LYPLAL1 rs4846567) and two BMI loci (LRRN6C rs10968576; MTIF3 rs4771122), for the respective BMI-adjustedWHR or BMI outcomes. Although the magnitudes of these select interactions were small, our data indicated that associations between genetic predisposition and obesity traits were stronger with a healthier diet. Our findings generate interesting hypotheses; however, experimental and functional studies are needed to determine their clinical relevance.Peer reviewe
The management of HCV-infected pregnant women
Hepatitis C is, at present, a worldwide health problem and is the most common cause of liver transplantation. Its prevalence in pregnant women is similar to that of the general population. In the absence of cirrhosis and portal hypertension, most HCV-infected pregnant women do not have obstetric complications. Screening of pregnant women that are asymptomatic and do not have risk factors is not cost effective. A high hepatitis C viral load reportedly increases vertical transmission and is higher in women who are coin-fected with HIV or who are intravenous drug users. Prolonged rupture of the membrane for more than 6 h, amniocentesis, and perineal lacerations increase the potential risk of perinatal transmission. Although the hepatitis C virus can be transmitted intrapartum, prevention by caesarean delivery is not generally indicated. The HCV virus can be found in maternal milk; however, breast feeding is not contraindicated. In conclusion, there are no antiviral treatment recommendations for HCV-infected women during pregnancy, or guidelines for the prevention of vertical transmission
