ABSTRACT

Biotechnology offers solutions and opportunities to meet various societal demands, thereby contributing to significant scientific advancements. This study aimed to characterize the technological development of biotechnology in the healthcare sector in the state of Rio Grande do Sul, Brazil, from 2016 to 2022 by analyzing patents filed by and granted to public and private Higher Education institutions. For data collection, a quantitative exploratory approach was employed using statistical methods and a patent analysis of institutions in the patent database of the Brazilian National Institute of Industrial Property (INPI), focusing on patents related to the healthcare field. Data were collected in October, November, and December. A total of 580 patent records were collected from the INPI, belonging to Sections A and C of the International Patent Classification (IPC) related to educational institutions. Furthermore, this study highlighted that higher education institutions have a higher number of patents in the healthcare field. These results provide an understanding of the strategic areas for technological development in biotechnology in Rio Grande do Sul, Brazil.

ABSTRACT

The main objective of this study was to evaluate the effects of supplementation the diet of pigs with grape pomace preserved in silage form (GPS) and its interaction with indoor and outdoor production systems, with and without access to vegetation, on the attributes of meat quality produced. Analyzes of proximal composition, cholesterol content, fatty acid profile, shear force, texture profile and sensory analysis were performed. During cold storage, oxidative stability and objective color were analyzed. Statistical analysis was performed in a 3×2 factorial design (production systems (S) x GPS-feed (F)) and the interaction between them (S*F). The results showed that there was no interaction between the production system and GPS feeding for the attributes evaluated. The proximate composition and fatty acid profile of the muscle remained unchanged. Additionally, it provides higher subjective and objective tenderness, higher red color intensity, and reduces lipid oxidation under refrigeration. The supplementation of pig feed with GPS improve the quality of the meat and constitute a sustainable alternative for the winemaking residue.

ABSTRACT

OBJECTIVE: The aim of this study was to determine the effect of anxiety and depression on pregnancy outcome in couples receiving in vitro fertilization treatment.

METHODS: A total of 102 couples (102 females and 102 males) with unexplained infertility were included in the study. Personal Information Form was used to collect data, Case Follow-up Form to record the treatment process, and Spielberger’s State-Trait Anxiety Inventory and Beck Depression Inventory to measure the anxiety and depression levels of couples. Couples were measured twice: before treatment and on oocyte pickup day.

RESULTS: There was no statistically significant difference between the anxiety and depression levels and oocyte count of women (p>0.05). There were statistically significant differences between State-Trait Anxiety Inventory level and sperm count and between BID level and sperm motility (p<0.05). There was no statistically significant difference between the anxiety and depression levels and pregnancy outcomes of women (p>0.05).

CONCLUSION: Anxiety and depression had no effect on pregnancy outcome. More studies are needed to investigate the effect of anxiety and depression on pregnancy outcome in unexplained infertility.

ABSTRACT

OBJECTIVE: This study aimed to investigate the effects of weight gain and maternal anemia on postpartum depression.

METHODS: This is a prospective, single-center, case-control study. We recorded the demographic characteristics, blood ferritin level, and weight gain during the pregnancy. This study was planned between April 2023 and June 2023 in the Obstetrics and Gynecology Clinic of Ankara Etlik City Hospital. A total of 109 patients were enrolled in the study. Patients were assessed with the Edinburgh Postpartum Depression Scale. Weight gain, nutritional education, educational level, mode of delivery, and pregnancy history were asked in person. Ferritin levels at the onset of labor were determined to detect anemia. Twin births, births due to fetal anomalies or intrauterine stillbirths, patients with systemic infections, and patients diagnosed with a psychiatric disorder in the past 6 months whose records were not accessible were excluded from the study.

RESULTS: Pregnancy weight gain and percentage of pregnancy weight gain were higher. Serum ferritin levels and nutritional education during pregnancy were lower in the postpartum depression group (p<0.001). These parameters with statistical significance were identified as risk factors in the regression analysis for postpartum depression (p<0.05). In receiver operating characteristics analysis, >15 kg for weight gain, >28.8 for percentage of weight gain in pregnancy, and <19 ng/dL for serum ferritin level were identified as cutoff values (p<0.001).

CONCLUSION: Nutritional education and vitamin supplementation should be recommended to pregnant women during routine examinations.

ABSTRACT

OBJECTIVE: The coronavirus disease 2019 pandemic that has emerged recently has significantly affected and continues to affect our lives. The Severe Acute Respiratory Syndrome Coronavirus 2 virus has significant effects on women’s health due to gender-related physiological differences. The aim of this study was to compare the menstrual cycle status of young women according to their status of having had coronavirus disease 2019.

METHODS: This descriptive cross-sectional study was conducted with 220 young women aged between 18 and 25 years who received at least one dose of coronavirus disease 2019 vaccine. The study data were collected as a survey on the online platform.

RESULTS: The descriptive characteristics of young women who had had and had not had coronavirus disease 2019 were distributed homogeneously between the groups (p>0.05). Furthermore, there was no statistical difference in terms of menstrual cycle patterns (p>0.05). The mean scores from the Premenstrual Syndrome Scale and its subscales and the mean scores from the COVID Stress Scale and its subscales were similar in both groups, and no statistically significant difference was identified (p>0.05).

CONCLUSION: Although menstrual cycle irregularities due to coronavirus disease 2019 have been reported, these effects are usually observed during the pandemic. A decrease in stress and anxiety with the end of the pandemic may explain the return of the menstrual cycle to normal.

ABSTRACT

OBJECTIVE: The aim of this study was to estimate the prevalence of influenza immunization in elderly people in Brazil in 2019.

METHODS: This is a population-based cross-sectional study. The Brazilian individuals (≥60 years) who participated in the 2019 National Health Survey were included. The survey was conducted in permanent households in Brazil from August 2019 to March 2020. The prevalences of influenza vaccination and their respective confidence intervals (95%CI) were estimated according to sociodemographic characteristics and the diagnosis of chronic diseases.

RESULTS: The prevalence of influenza vaccination was 72.4% (95%CI 71.5-73.2), with statistically significant differences observed between genders (p=0.001), age groups (p=0.001), and those living with a spouse/partner (p=0.002). Significant differences were found in groups with arterial hypertension (75.2%, p<0.001), diabetes (77.2%, p<0.001), and arthritis or rheumatism (75.5%, p<0.001).

CONCLUSION: A global prevalence of influenza vaccination of 72.4% was estimated among elderly people in Brazil.

ABSTRACT

OBJECTIVE: This study aimed to determine the thoracic and extra-thoracic extension of the disease in patients diagnosed with lung cancer and who had whole-body F18-fluorodeoxyglucose positron emission tomography/CT imaging and to investigate whether there is a relationship between tumor size and extrathoracic spread.

METHODS: A total of 308 patients diagnosed with lung cancer were included in this study. These 308 patients were first classified as group 1 (SPN 30 mm>longest lesion diameter ≥10 mm) and group 2 (lung mass (longest lesion diameter ≥30 mm), and then the same patients were classified as group 3 (nodular diameter of ≤20 mm) and group 4 (nodular size of >20 mm). Group 1 was compared with group 2 in terms of extrathoracic metastases. Similarly, group 3 was compared with group 4 in terms of frequency of extrathoracic metastases. F18 fluorodeoxyglucose positron emission tomography/CT examination was used to detect liver, adrenal, bone, and supraclavicular lymph node metastasis, besides extrathoracic metastasis.

RESULTS: Liver, bone, and extrathoracic metastasis in group 1 was statistically lower than in group 2 (p<0.001, p<0.01, and p=0.03, respectively). Liver, extrathoracic, adrenal, and bone metastasis in group 3 was statistically lower than that in group 4 (p<0.001, p=0.01, and p=0.04, p<0.01, respectively). The extrathoracic extension was observed in only one patient in group 3. In addition, liver, adrenal, and bone metastases were not observed in group 3 patients.

CONCLUSION: Positron emission tomography/CT may be more appropriate for cases with a nodule diameter of ≤20 mm. Performing local imaging in patients with a nodule diameter of ≤20 mm could reduce radiation exposure and save radiopharmaceuticals used in positron emission tomography/CT imaging.

ABSTRACT

OBJECTIVE: This study aimed to evaluate occlusion development after premature loss or extraction of deciduous anterior teeth, by means of a prospective cohort study.

METHODS: Fifteen infants and children aged 1 to 5 years old were longitudinally assessed (with loss or extraction of deciduous anterior teeth [n = 9], and without tooth losses [n = 6]). Photographs and dental casts at the baseline and after 24 months of follow-up were performed. Dental casts were scanned, and linear measurements were made on the digitalized models (missing tooth space, arch perimeter, arch length, arch width, intercanine length and intercanine width). The t-test was used for groups comparisons (α = 0.05).

RESULTS: Individuals’ mean age at baseline was 2.93 (± 1.18) years. No statistically significant differences were observed in the missing tooth space in the group with tooth loss during the 24 months of follow-up (p > 0.05). Arch perimeter, arch length, arch width, intercanine length and intercanine width did not show differences between the groups (p > 0.05). Qualitative photographic evaluation revealed other changes in the dental arches and occlusion, such as exfoliation and eruption of deciduous teeth, eruption of permanent teeth, self-correction or establishment of malocclusion, among others.

CONCLUSION: The results suggest that the premature loss of deciduous anterior teeth does not affect the perimeter, length and width of the dental arches; however, other alterations that lead to malocclusion could be established.

ABSTRACT

BACKGROUND: Cancer screening is absolutely necessary in patients with pericardial effusion, given that cancer is one of the most serious diseases in the etiology of pericardial effusion. In previous studies, it was stated that the systemic immune-inflammation index (SII); the prognostic nutrition index (PNI); and the hemoglobin, albumin, lymphocyte, platelet (HALP) score can produce scores related to cancer.

OBJECTIVES: This study began considering that these scoring systems could predict cancer in the etiology of patients with pericardial effusion.

METHODS: This study produced a retrospective analysis of patients who underwent pericardiocentesis between 2006 and 2022. Pericardiocentesis was performed in a total of 283 patients with moderate-to-large pericardial effusion or pericardial tamponade within the specified period. HALP, PNI, and SII scores were calculated according to the peripheral venous blood taken before the pericardiocentesis procedure. The statistical significance level was set at p<0.05.

RESULTS: The HALP score proved to be 0.173 (0.125-0.175) in cancer patients and 0.32 (0.20-0.49) in non-cancer patients (p<0.001). The PNI score proved to be 33.1±5.6 in cancer patients and 39.8±4.8 in non-cancer patients (p<0.001).

CONCLUSION: The HALP score and PNI proved to be easy and fast cancer screening tests that can predict cancer metastasis in the etiology of patients with pericardial effusion.

ABSTRACT

BACKGROUND: Untreated multivessel disease (MVD) in acute myocardial infarction (AMI) has been linked to a higher risk of recurrent ischemia and death within one year . Current guidelines recommend percutaneous coronary intervention (PCI) for significant non-infarct artery (-ies) (non-IRA) stenosis in hemodynamically stable AMI patients with MVD, either during or after successful primary PCI, within 45-days. However, deciding the timing of revascularization for non-IRA in cases of MVD is uncertain.

METHODS: This meta-analysis was performed based on PRISMA guidelines after registering in PROSPERO (CRD42023472652). Databases were searched for relevant articles published before 10 November 2023. Pertinent data from the included studies were extracted and analyzed using RevMan v5.4.

RESULTS: Out of 640 studies evaluated, there were 13 RCTs with 5144 patients with AMI with MVD. The immediate non-IRA PCI is associated with a significantly lower occurrence of unplanned ischemia-driven PCI (OR 0.60; confidence interval [CI] 0.44-0.83) and target-vessel revascularization (OR 0.72; CI 0.53-0.97) . Although there is a favorable trend for major adverse cardiovascular and cerebrovascular events (MACCE), nonfatal AMI, cerebrovascular events, and major bleeding in the immediate non-culprit artery (-ies) PCI, those were statistically non-significant. Similarly, all-cause mortality, cardiovascular mortality, stent thrombosis, and acute renal insufficiency did not show significant differences between two groups.

CONCLUSION: Among hemodynamically stable patients with multivessel AMI, the immediate PCI strategy was superior to the multistage PCI strategy for the unplanned ischemia-driven PCI and target-vessel revascularization while odds are favorable in terms of MACCE, nonfatal AMI, cerebrovascular events, and major bleeding at longest follow-up.
