SUMMARY OBJECTIVE: The vast majority of patients who hospitalized with coronavirus disease 2019 are given empirical antibiotic therapy. However, information on the frequency, microorganism species, and resistance rates of secondary bacterial infections in coronavirus disease 2019 patients are insufficient. We aimed to show the frequency of secondary infections and resistance conditions in patients with coronavirus disease 2019 hospitalized in the intensive care unit. METHODS: The results of tracheal aspirate culture, blood culture, and urine culture obtained from coronavirus disease 2019 patients – at least 2 days after their admission to the intensive care unit – were examined microbiologically. RESULTS: A total of 514 patients hospitalized in intensive care unit were included in our study. Tracheal aspirate, blood, or urine cultures were collected from 369 patients (71.8%). Bacterial reproduction was detected in at least one sample in 171 (33.3%) of all patients. The rate of respiratory tract infection and/or bloodstream infection was found to be 21%. Acinetobacter baumannii, Klebsiella pneumoniae, and Pseudomonas aeruginosa in tracheal aspirate culture; Coagulase-negative staphylococci, K. pneumoniae, and A. baumannii in blood culture; and Escherichia coli, K. pneumoniae, and Enterococcus faecalis in urine culture were the most common microorganisms. A. baumannii was resistant to most antibiotics except colistin and P. aeruginosa strains were resistant to most antibiotics except amikacin, colistin, cefepime, and imipenem. In K. pneumoniae, the highest meropenem sensitivity (73%) was observed; there was a strong resistance to most of the remaining antibiotics. CONCLUSIONS: We think that our study can be useful in choosing empirical antibiotic therapy in the coronavirus disease 2019 pandemic and reducing the mortality that may occur with secondary infection.

SUMMARY OBJECTIVE: Beta-thalassemia minor is a blood disease caused by a hereditary decrease in beta-globin synthesis, frequently leading to hypochromic microcytic anemia. Formerly called endothelial cell-specific molecule 1, endocan is a proteoglycan released by vascular endothelial cells in many organs. Our aim was to investigate the relationship between the beta-thalassemia minor patients and the healthy control group in terms of serum endocan level. METHODS: The study was performed in a total of 80 subjects. They were divided into two groups, the beta-thalassemia minor group (n=40) and the healthy control group (n=40). Serum endocan levels, age, sex, body mass index value, and tobacco use data of these groups were compared. RESULTS: No statistically significant difference was detected between the two groups in terms of age, sex, and body mass index values (p>0.05). Endocan levels were measured to be 206.85±88.1 pg/mL in the beta-thalassemia minor group and 236.1±162.8 pg/mL in the control group with no significant difference between the groups in terms of serum endocan levels (p>0.05). CONCLUSIONS: In our study, there was no change in endocan level in beta-thalassemia minor. This might be because serum endocan levels are affected by multi-factorial reasons. Serum endocan levels may be altered secondarily to decreased beta-globin chain, increased sympathetic activity due to anemia, or platelet dysfunction induced by oxidative stress in beta-thalassemia minor. Further multicenter studies involving more patients are necessary to demonstrate this.

SUMMARY OBJECTIVE: This study aimed to determine the relationship of the prenatal psychosocial profile with postpartum maternity duties and newborn care. METHODS: This descriptive and correlational study was conducted on 154 pregnant women. RESULTS: It was determined that pregnant women had low-stress levels, high social support from their husbands and other people, and moderate self-esteem. Participants relying on power in coping with maternity duties in the postpartum period and satisfaction with maternity and newborn care were found to be high. CONCLUSION: Adaptation to the postpartum period facilitates the transition to maternity and increases satisfaction with newborn care.

SUMMARY OBJECTIVE: The objective of this study was to explore the molecular mechanism underlying the occurrence of benign bile duct stricture and the target of low-dose paclitaxel in the prevention of benign bile duct stricture. METHODS: Under the stimulation of transforming growth factor beta 1, the expression of collagen type I and connective tissue growth factor were detected on isolated primary fibroblasts. The phosphorylation levels of JNK and Smad2L were detected using Western blot. The effect of low-dose paclitaxel on the transforming growth factor beta 1-induced inhibition of type I collagen and connective tissue growth factor expression and JNK and Smad2L phosphorylation was also observed. RESULTS: Transforming growth factor beta 1 induced the secretion of type I collagen and connective tissue growth factor as well as JNK phosphorylation in biliary fibroblasts. The JNK inhibitor or siRNA-Smad2 inhibited the transforming growth factor beta 1-induced secretion of type I collagen and connective tissue growth factor. Low-dose paclitaxel inhibited the expression of type I collagen induced by transforming growth factor beta 1 and may inhibit the secretion of collagen in biliary fibroblasts. CONCLUSION: The activation of JNK/Smad2L induced by transforming growth factor beta 1 is involved in the occurrence of benign bile duct stricture that is mediated by the overexpression of type I collagen and connective tissue growth factor, and low-dose paclitaxel may inhibit the phosphorylation of JNK/Smad2L.

SUMMARY OBJECTIVE: In this study, we evaluated the clinical characteristics and seasonal distribution of patients with primary spontaneous pneumothorax and examined the relationships between meteorological factors and pneumothorax development overall and in terms of first episode and recurrence. METHODS: The hospital records of 168 pneumothorax patients treated in our clinic between January 2016 and December 2020 were reviewed retrospectively. A cluster was defined as two or more patients with pneumothorax presenting within three consecutive days. Meteorological factors were compared between days with and without pneumothorax patients. This comparison was based on meteorological data from the day of symptom onset (D), the day before symptom onset (D1), and the difference between those days (D–D1). Meteorological data from the index day (D) were also compared between patients with first episode and recurrence of pneumothorax. RESULTS: The study included 149 (88.7%) men and 19 (11.3%) women. The mean age was 25.02±6.97 (range, 17–35; median, 26) years. Of note, 73 (43.4%) patients underwent surgery. The highest number of patients presented in November (n=19, 11.3%). In terms of season, most presentations occurred in autumn. Humidity was significantly lower on recurrence days compared with first episode (p=0.041). CONCLUSION: Our results indicated that meteorological factors (i.e., atmospheric pressure, humidity, wind speed, temperature, and precipitation) were not associated with pneumothorax development. By comparing the patients with first episode and recurrence, the humidity was significantly lower in the recurrence group.

SUMMARY OBJECTIVE: A growing volume of literature has suggested long noncoding RNAs (lncRNAs) as important players in tumor progression. In this study, we aimed to investigate the expression and prognostic value of lncRNA LINC00173 (LINC00173) in melanoma. METHODS: LINC00173 expression was measured in 163 paired cancerous and noncancerous specimen samples by real-time polymerase chain reaction. The correlations between LINC00173 expression with clinicopathological characteristics and prognosis were analyzed by chi-square test, log-rank test, and multivariate survival analysis. Receiver-operating characteristic curves were used for the assessment of the diagnostic value of LINC00173 for melanoma patients. RESULTS: The expression level of LINC00173 in melanoma specimens was distinctly higher than that in adjacent non-neoplasm specimens (p<0.01). Besides, LINC00173 was expressed more frequently in patients with advanced melanoma than in patients with early melanoma. Multivariate assays confirmed that LINC00173 expression level was an independent prognostic predictor of melanoma patients (p<0.05). CONCLUSION: Our data indicated that LINC00173 expression could serve as an unfavorable prognostic biomarker for melanoma patients.

SUMMARY OBJECTIVES: Cardiovascular diseases are also considered to increase the risk of death in COVID-19 patients. However, real-world data concerning the risk factors for death in patients with severe COVID-19 still remain vague. This study aimed to identify the potential risk factors associated with mortality in severe COVID-19 patients. METHODS: All consecutive patients admitted to the intensive care unit (ICU) of our institute for COVID-19 for severe COVID-19 pneumonia from April 1, 2020 to July 20, 2020 were included in the analysis. Patient characteristics, including complete medical history and comorbid diseases, blood test results during admission and on day 7, and clinical characteristics were compared between survivors and nonsurvivors. RESULTS: There was no significant difference between survivors and nonsurvivors regarding age, gender, and preexisting cardiovascular diseases. Moreover, the rate of the medications including angiotensin-converting enzyme (ACE) inhibitor and angiotensin receptor blockers did not differ between survivors and nonsurvivors. The peak C-reactive protein (CRP), procalcitonin, fibrinogen, and d-dimer levels and the rate for chronic renal failure were significantly higher in nonsurvivors compared with survivors. Intubated patients had a higher risk of death than the others had. CONCLUSIONS: This study failed to demonstrate a significant difference in preexisting cardiovascular diseases and cardiovascular medications between survivors and nonsurvivors who were admitted to ICU for severe COVID-19. Our findings indicate that the presence of chronic renal failure, a high peak ferritin concentration, and the need for invasive mechanical ventilation appear predictive for mortality. We propose that these risk factors should be taken into account in defining the risk status of severe COVID-19 patients admitted to the ICU.

SUMMARY OBJECTIVE: The aim of this study was to ascertain the long-term respiratory effects of COVID-19 pneumonia through pulmonary function tests in follow-ups at 1 and 6 months. METHODS: Our study was conducted between August 1, 2020 and April 30, 2021. At 1 month after discharge, follow-up evaluations, PFTs, and lung imaging were performed on patients aged above 18 years who had been diagnosed with COVID-19 pneumonia. In the 6th month, the PFTs were repeated for those with pulmonary dysfunction. RESULTS: A total of 219 patients (mean age, 49±11.9 years) were included. Pathological PFT results were noted in the 1st month for 80 patients and in the 6th month for 46 (7 had obstructive disorder, 15 had restrictive disorder, and 28 had small airway obstruction) patients. A significant difference was found between abnormal PFT results and patient-described dyspnea in the 1st month of follow-up. The 6-month PFT values (especially those for forced vital capacity) were statistically significantly lower in the patients for whom imaging did not indicate complete radiological improvement at the 1-month follow-up. No statistically significant difference was found between the severity of the first computed tomography findings or clinical condition on emergency admission and pulmonary dysfunction (Pearson’s chi-square test, P=0.904; Fisher’s exact test, P=0.727). CONCLUSION: It is important that patients with COVID-19 pneumonia be followed up for at least 1 month after discharge to be monitored for potential long-term lung damage. PFTs should be administered to those in whom ongoing dyspnea, which started with COVID-19, and/or full recovery were not identified in pulmonary imaging.

SUMMARY OBJECTIVE: Since the start of the COVID-19 pandemic, there has been interest in the impact of both SARS-CoV-2 infection and pandemic-induced social restrictions on male reproductive health. This study aimed to evaluate the spermiogram values of men who presented for infertility during the pandemic compared with the previous 2 years. METHODS: Patients who presented to a urology outpatient clinic for the first time due to infertility were included. The patients’ age, semen volume, and spermiogram results were recorded. Based on the presentation date, the patients were divided into prepandemic group 1 (March 2018–February 2019), prepandemic group 2 (March 2019–February 2020), and pandemic group (March 2020–February 2021) for comparison. RESULTS: A total of 594 patients were included. There was no significant difference between the three groups in terms of the number of patients who presented for infertility (207, 190, and 197 patients, respectively; p=0.691). The mean age was 36.6±7.2 in the prepandemic group 1, 35.5±7.1 in the prepandemic group 2, and 33.1±6.3 in the pandemic group. Patients who presented during the pandemic were significantly younger (p<0.001). There were no differences between the groups in terms of semen volume (p=0.910) or rates of normospermia and pathological spermiogram findings (p=0.222). CONCLUSIONS: In the first year of the COVID-19 pandemic, there was no significant difference in the number of patients who presented for infertility or in their spermiogram results compared with 2018 and 2019. However, it is noteworthy that the patients were significantly younger during the pandemic than in the previous 2 years.

SUMMARY OBJECTIVE: COVID-19 outbreak has become widespread globally and caused a new global chaos. This outbreak that completely affected the lifestyle of individuals resulted in periods of isolation. Here, we evaluated the effects of lifestyle changes with isolation on constipation. METHODS: A survey on constipation was performed during the 12-week isolation period starting in March 2020 in Turkey. Data of 390 individuals who participated in the survey through the social media and who were actively employed prior to isolation were analyzed. Rome IV criteria were used to evaluate constipation. RESULTS: Among the participants in the study, 253 (64.9%) were women with the mean age of 39.5±9.5 years. A statistically significant association was found between the decreased water consumption during the isolation period and constipation after the isolation (p=0.020; p<0.05). A significant association was found between the changes in physical activity and constipation after the isolation (p=0.013; p<0.05). New development of constipation during the isolation or declaration of increased constipation was found to be statistically associated with post-isolation constipation according to Rome criteria (p=0.000; p<0.05). CONCLUSION: The data of this present study demonstrated that isolation period was effective on the newly developed constipation. Decreased physical activity and water consumption are also effective on constipation.

SUMMARY OBJECTIVE: The objective of this study was to emphasize the importance of legal and bioethical knowledge in maintaining medical confidentiality, especially in situations when there is a diagnosis of HIV infection. METHODS: A literature review of studies published in the Scientific Electronic Library Online and National Library of Medicine databases was performed. Sixteen studies available in full, online, and free, published between 2010 and 2020, were selected. RESULTS: The studies highlighted that, despite the ethical duty to breach confidentiality for the protection of third parties, many doctors are reluctant to reveal this secret due to the power of stigmatization and social discrimination related to the diagnosis of HIV infection, which affects integrity, counseling, and capability to treat patients. CONCLUSION: HIV diagnosis implies bioethical and legal questions. Respect for medical confidentiality is a matter to be discussed, as there is a need to protect the privacy of the patient, at the same time the responsibility to preserve the health of others.

SUMMARY OBJECTIVE: A multicentric, cross-sectional study was carried out to determine the prevalence and risk factors for Coronavirus disease 2019 in medical students and residents from four universities and affiliated hospitals in Brazil. METHODS: A survey about contamination risk and symptoms was sent to all participants through email and WhatsApp. Prevalence was measured by the self-report of positive polymerase chain reaction or serological test. Univariate and multivariate analyses were performed, and odds ratio and 95% confidence interval were calculated. RESULTS: Prevalence of infection by Sars-CoV-2 was 14.9% (151/1011). The disease was more prevalent in residents and interns than in undergraduate students. Contact with an infected relative outside the hospital or with colleagues without using personal protective equipment was associated with higher contamination. Contact with patients without wearing goggles and higher weekly frequency of contact were the two factors independently associated with the infection by Coronavirus disease 2019 in the multivariate analysis. CONCLUSIONS: Medical students, interns, and residents have a higher prevalence of Coronavirus disease 2019 than the general population, in which the last two groups are significantly at higher risk. Contacting patients at a higher weekly frequency increases the risk for infection. The use of goggles should be reinforced when contacting patients.

SUMMARY OBJECTIVE: Neonates are more susceptible to drug interactions and adverse effects, and special care should be taken when prescribing medication to them. This study aimed to investigate drug usage in the neonatal intensive care unit of a tertiary care hospital. METHODS: This prospective observational study was conducted on 98 patients at the Apollo tertiary care hospital (Bannerghatta, Bangalore, India) in a period of 6 months. The most common indications for neonatal intensive care unit admission, average number of drugs per patient, the most frequently used medication, distribution of patients based on the birth procedure, and possible drug interactions were collected from patient profiles. RESULTS: Among the patients, 52% were males and 48% were females. Notably, 38% of patients were preterm, 60% were term, and only 2% were post-term. Also, 80.6% were born by cesarean section and 19.4% were born by normal vaginal delivery. The highest mean of drug use was in the patient of 1,000–1,500 g (8.06 per patient). Preterm was the most frequent indication for admission in neonatal intensive care unit, followed by hyperbilirubinemia and then respiratory distress syndrome. The most frequently used medication was vitamin K (99%) and antibiotics followed by dextrose. In different types of antibiotics, amikacin (41%), cefoperazone+sulbactam (35%), cephalosporin (1%), ceftriaxone (0.7%), and amoxicillin (0.3%) were commonly administered. There were some possible interactions, such as aminoglycoside with furosemide and calcium gluconate. CONCLUSION: Premature birth and resulting low birth weight were the main reasons for drug prescription. High administration of antibiotics is probably an area of concern and should be seriously considered.

SUMMARY OBJECTIVE: This study aimed at the oral health problems of elderly patients with diabetes. A training course of integrated traditional Chinese and Western medicine was constructed, helping patients improve their oral health quality of life. METHODS: A randomized controlled prospective experimental study was conducted. A total of 190 elderly patients were divided randomly into an observation group and a control group with 95 cases in each. The control group received regular health education, while the observation group was based on the control group to implement the integrated experiential learning of traditional Chinese and Western medicine in small groups. The oral health knowledge, attitude, behavior, and blood glucose control status along with the oral health quality of life of the two groups were compared before the intervention and at 3-month postintervention. RESULTS: Three months after the intervention, the fasting blood glucose control and the 2-h postprandial blood glucose/glycosylated hemoglobin levels in the observation group were significantly better than in the control group, and the difference was statistically significant (p<0.05). The oral health quality of life in the observation group was significantly better than in the control group, and the difference was statistically significant (p<0.05). CONCLUSION: The small-group experiential learning model of integrated Chinese and Western medicine can promote the transformation of knowledge–beliefs–behaviors in elderly patients with diabetes, which is conducive to controlling blood sugar levels and improving the quality of oral health.

SUMMARY OBJECTIVE: This study aimed to investigate the suboptimal health status or subhealth status and their relationship with mental health and smartphone addiction among Chinese medical students. METHODS: A cross-sectional survey was conducted at Wannan Medical College of China in Wuhu. RESULTS: A total of 2,741 students were surveyed in October 2020. Of 2,741 Chinese medical students who completed the survey, 904 (33%) participants reported to have had subhealth status. Anxiety status (p<0.001), depression status (p<0.001), and smartphone addiction status (p<0.001) have strong association with subhealth status. CONCLUSION: This survey shows that the detection rate of subhealth status in Chinese medical students was 33%. Anxiety, depression, and smartphone addiction students had a higher detection rate of subhealth status. The anxiety, depression, and smartphone addiction of Chinese medical students are associated with subhealth status.

SUMMARY OBJECTIVE: The stroma surrounding the tumor cells is important in tumor progression and treatment resistance, besides the properties of tumor cells. Studies on the tumor stroma characteristics will contribute to the knowledge for new treatment approaches. METHODS: A total of 363 breast cancer patients were evaluated for the tumor–stroma ratio. The percentage of stroma was visually assessed on hematoxylin–eosin stained slides. The cases of tumor–stroma ratio more than 50% were categorized as tumor–stroma ratio high, and those less than 50% and below were categorized as tumor–stroma ratio low. RESULTS: Tumor–stroma ratio-high tumors had shorter overall survival (p=0.002). Disease-free survival tended to be shorter in tumor–stroma ratio-high tumors (p=0.082) compared with tumor–stroma ratio-low tumors. Tumor–stroma ratio was an independent prognostic parameter for the total group of patients (p=0.003) and also axillary lymph node metastasis and tumor–stroma ratio was statistically associated (p=0.004). Also, tumor–stroma ratio was an independent prognostic parameter in node-positive Luminal A and B subgroups for overall survival (p<0.001). CONCLUSION: Tumor–stroma ratio is an independent prognostic parameter that can be evaluated quite easily in all molecular subtypes of all breast cancers and does not require extra cost and time to evaluate.

SUMMARY OBJECTIVE: The objective of this study was to verify whether the parameters of the blood count and the fasting glucose level before treatment are related to prognosis and survival in cervical cancer (IIB–IVB staging). METHODS: Patients with cervical cancer (stages IIB–IVB) were evaluated (n=80). Age, parity, staging, histological grade, histological type, hemoglobin, red blood cells, hematocrit, neutrophil, lymphocyte and platelet counts, red blood cell distribution width, neutrophil–lymphocyte ratio, platelet–lymphocyte ratio, fasting glucose levels, overall survival, and disease-free survival were evaluated. The results of laboratory parameters were compared using the Mann–Whitney U test. Receiver operating characteristic curve was used to obtain the area under the curve and determine the best cutoff values for each parameter. Survival was verified by using the Kaplan–Meier method, followed by the log-rank test. The level of significance was ≤0.05. RESULTS: Regarding staging, lower hemoglobin values (p=0.0013), red blood cells (p=0.009), hematocrit (p=0.0016), higher leukocytes (p=0.0432), neutrophils (p=0.0176), platelets (p=0.0140), red blood cell distribution width (RDW) (p=0.0073), neutrophil–lymphocyte ratio (p=0.0039), platelet–lymphocyte ratio (p=0.0006), and fasting glucose level (p=0.0278) were found in IIIA–IVB compared with IIB staging. Shorter disease-free survival was associated with hemoglobin ≤12.3 g/dl (p=0.0491), hematocrit ≤38.5% (p=0.05), neutrophil–lymphocyte ratio >2.9 (p=0.0478), and platelet–lymphocyte ratio >184.9 (p=0.0207). Shorter overall survival was associated with hemoglobin ≤12.3 g/dl (p=0.0131), hematocrit ≤38.5% (p=0.0376), neutrophil–lymphocyte ratio >2.9 (p=0.0258), and platelet–lymphocyte ratio >184.9 (p=0.0038). CONCLUSION: The analysis of these low-cost and easily accessible parameters could be a way to monitor patients in order to predict treatment failures and act as early as possible.

SUMMARY OBJECTIVE: The objectives of this study were to identify predictors of mortality in young adult patients with coronavirus disease 2019 and to assess the link between blood type and mortality in those patients. METHODS: This multicenter retrospective study, which was conducted in seven training and research hospitals in Istanbul, involved young adults who aged ≥18 and <50 years and hospitalized with coronavirus disease 2019. RESULTS: Among 1,120 patients, confusion at admission (p<0.001) and oxygen saturation (p<0.001) were significantly predictive factors of mortality. Blood type O was significantly associated with mortality compared to those discharged from the hospital (p<0.001). Among co-morbidities, the most reliable predictive factors were cerebral vascular disease (p<0.001) and chronic renal failure (p=0.010). Among laboratory parameters, high C-reactive protein (p<0.001) and low albumin (p<0.001) levels were predictors of mortality in young adult patients with coronavirus disease 2019. CONCLUSIONS: SpO2 at admission was the best predictor of mortality in young adult patients with coronavirus disease 2019. The mortality rate was increased by cerebral vascular disease and chronic renal failure. Also, high C-reactive protein and low albumin levels were predictive factors of mortality. Moreover, blood type O was associated with a higher mortality rate than the other types.

SUMMARY BACKGROUND: The infection caused by coronavirus disease 2019 can lead to respiratory sequelae in individuals who have experienced severe or mild symptoms. METHODS: An observational, cross-sectional study was developed, following the STROBE guidelines. Maximal inspiratory and expiratory mouth pressures were assessed in 50 healthy young students (26 women, 24 men; age 22.20±2.41 years). The inclusion criteria were as follows: aged between 18 and 35 years; control group: not diagnosed with coronavirus disease 2019; and coronavirus disease 2019 group: diagnosed with coronavirus disease 2019, at least 6 months ago. The exclusion criteria were as follows: obese/overweight; infected with coronavirus disease 2019 or coronavirus disease 2019 symptoms in the last 6 months; smokers; and asthmatics. RESULTS: When comparing with groups, the coronavirus disease 2019 group presented statistically significant lower maximal inspiratory pressure values compared with the control group (88.32±16.62 vs. 101.01±17.42 cm H2O; p=0.01). Regarding the maximal expiratory pressure, no significant differences were found. Similar results were found when performing a subgroup analysis by sex and group. CONCLUSIONS: Young students who suffered from coronavirus disease 2019 asymptomatically or mildly at least 6 months ago presented a significant decrease in the inspiratory muscle strength as a sequel, so we believe that patients affected by this disease should have a brief postinfection assessment of this musculature to detect the indication for cardiorespiratory rehabilitation.

SUMMARY OBJECTIVE: The metabolic syndrome involves both metabolic and cardiovascular risk factors and is associated with cardiovascular mortality. Epicardial fat tissue plays a crucial role in deleterious effects of metabolic syndrome on the heart, including myocardial fibrosis. The fragmented QRS reflects heterogeneous depolarization of the myocardium and occurs as a result of fibrosis. Thus, we aimed to investigate whether there is an association between fragmented QRS and epicardial fat tissue in patients with metabolic syndrome. METHODS: This study enrolled 140 metabolic syndrome patients, of whom 35 patients with fragmented QRS (+) and 105 patients with fragmented QRS (−). The two groups were compared with respect to clinical, laboratory, electrocardiographic, and echocardiographic indexes. RESULTS: Fragmented QRS (+) patients had higher waist circumference, red cell distribution width, creatinine, left ventricular end-systolic diameter, left atrium diameter, septal a velocity, QRS duration, and epicardial fat tissue compared with fragmented QRS (−) patients. Waist circumference, red cell distribution width, QRS duration, left ventricular end-systolic diameter, left atrium diameter, septal a velocity, and epicardial fat tissue were significantly associated with the presence of fragmented QRS. The QRS duration and epicardial fat tissue were independently associated with the presence of fragmented QRS on surface electrocardiographic in metabolic syndrome patients. CONCLUSIONS: Epicardial fat tissue and QRS duration were independently associated with the presence of fragmented QRS. Basic echocardiographic and electrocardiographic parameters might be used for the risk stratification in metabolic syndrome patients.

SUMMARY OBJECTIVE: The objective of this study was to analyze the relationship between the number of prenatal care visits and the occurrence of adverse perinatal outcomes in an average city in the state of Minas Gerais, Brazil. METHODS: This was a prospective and observational study. The variables analyzed were obtained through a questionnaire administered to postpartum women (between 1 and 48 h postpartum) and information contained in prenatal cards. The pregnant women were classified into three groups: Group I, <3 prenatal care visits; Group II, 3–5 prenatal care visits; and Group III, ≥6 prenatal care visits. RESULTS: Group I had a lower median weight (57.0 vs. 64.0 kg, p<0.001), body mass index (22.1 vs. 24.3 kg/m2, p<0.001), and weight gain (9.0 vs. 12 kg, p=0.002) than Group III. The prevalence of admission to the neonatal intensive care unit (11.6 vs. 4.2%, p=0.02) and the newborn mortality rate within the first 72 h of life (2.3 vs. 0%, p<0.001) were higher in Group I than in Group III. Group II had a higher prevalence of admission to the adult intensive care unit (5.7 vs. 0.6%, p<0.001) and a higher newborn mortality rate within the first 72 h of life (1.6% vs. 0%, p<0.001) than Group III. CONCLUSIONS: Having ≥6 prenatal care visits was associated with lower rates of admission to the neonatal and adult intensive care unit, as well as a lower newborn mortality rate within the first 72 h of life.
