This can occur by various mechanisms such as alterations at the gastroesophageal junction or diaphragmatic atrophy that can take place due to a number of reasons, including involutional changes, extensive trauma or damage to the phrenic nerve. Most cases are usually asymptomatic; however, when clinical manifestations occur, they vary depending on the size of the herniation and range from chest pain (also epigastric pain), nausea, vomiting to abdominal distension. In case of presenting complications such as gastric volvulus or Cameron lesions, the symptoms include Borchardt’s triad, which consists of abdominal pain and distension, violent vomiting and difficulty passing a nasogastric tube. We present the case of an 82-year-old male patient who was admitted to the emergency room for severe abdominal pain, severe hematemesis and sensory disorder. On physical examination, pale facies and diaphoresis were observed; on palpation, the main indication was abdominal pain in the epigastric area. Emergency endoscopy was requested, finding a deep ulcer with congestive edges and active bleeding in the lower portion of the esophagus, in addition to observing that part of the gastric fundus and the cardias were herniated toward the thorax. This confirmed the diagnosis of a giant hiatal hernia; however, the treatment was interrupted by the patient when he asked for voluntary discharge after refusing to undergo surgery.","PeriodicalId":396953,"journal":{"name":"Horizonte Médico (Lima)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125193863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and methods: An observational, analytical, correlational and prospective study carried out with 550 men and 700 women of all ages who attended monthly preventive-promotional health campaigns, as well as routine medical consultations, from January 2021 to June 2022. Collected data consisted of hematocrit, red blood cells and hemoglobin counts. The Spearman’s correlation coefficient was used. Results: There was a higher prevalence of anemia in the group of women older than 11 years (35.10 %), while hemoglobin levels in most children younger than 11 years were mainly normal. High and positive correlations between hemoglobin and hematocrit close to one were found in all age groups and both sexes. In addition, moderate and positive correlations were found in female infants and girls (Rho = 0.525), female adolescents (Rho = 624), as well as male infants and boys (Rho = 0.597). Conclusions: Hemoglobin levels are highly and positively correlated with hematocrit. Simultaneous hemoglobin and hematocrit testing may be clinically and economically unnecessary in screening and preventive-promotional campaigns on anemia conducted in large population groups. Likewise, hemoglobin correlates moderately and positively with red blood cell in children of both sexes and female adolescents. Further research is needed to deepen the reasons why correlation varies in these groups.","PeriodicalId":396953,"journal":{"name":"Horizonte Médico (Lima)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121881357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They have also been referred to as reactive oxygen species (ROS), reactive nitrogen species (RNS) or reactive sulfur species (RSS). In the human organism, they are mainly produced in the mitochondrial electron transport chain, where respiratory complexes I and III specifically participate and reduce oxygen by converting it into superoxide anion. Likewise, they can be formed through a wide variety of enzymatic and non-enzymatic reactions involving substances that are synthesized by cells or are ingested with food and some medicines. Human beings have an antioxidant system which is both enzymatic and non-enzymatic in nature and whose function is to protect the organism from the harmful action of free radicals. This system includes enzymes—such as catalase, superoxide dismutase, thioredoxin, etc.—and non-enzymatic compounds— such as glutathione, ferritin, myoglobin, etc. However, they are not efficient enough to protect it, so it is necessary to eat foods that contain substances with antioxidant properties whose protective action will depend on their chemical reactivity and their concentration. These antioxidant compounds are mainly found in fruits and vegetables, where polyphenols, flavonoids, carotenoids, vitamin C, vitamin E, etc. have been identified. A significant amount of evidence suggests that","PeriodicalId":396953,"journal":{"name":"Horizonte Médico (Lima)","volume":"213 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128168478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
