RESUMO

Background: Metrology plays a crucial role in small healthcare service businesses to ensure the quality of products and services. While legal metrology in healthcare exists in some regions, it lacks harmonization. In other countries, there is limited presence of metrology in medical and biomedical engineering. We aimed to evaluate the implementation of metrological assurance systems for medical devices in Latin America. Methods: A systematic review was conducted following PRISMA 2020 guidelines and registered with PROSPERO (CRD42022359284). Searches were performed across 13 databases from October 30th to November 3rd, 2022. The search equation was "(((quality assurance) AND (metrology)) AND (medical devices))." A total of 7,789 documents were identified, of which only 16 met the inclusion criteria. Results: The majority of studies (75%) were conducted in Colombia, with a significant portion being undergraduate theses. The primary normative references used in the analyzed studies were ISO 10012 and ISO 17025, with the majority (68.75%) relying on national legislation for their approach. One study in Colombia referenced eight standards, and one in Brazil analyzed user involvement in medical device management. Among the included studies, 56.25% were conducted in healthcare institutions, mainly clinics. Most studies provided implementation guidelines, with ISO 10012 being prominent, alongside ISO 17025, which implicitly addresses ISO 9001 elements. Global bias was low across all studies. Conclusion: Our results underscore the importance of metrological assurance in managing medical devices in Latin America. The utilization of international standards and national legislation illustrates the diverse approaches adopted by different institutions. Future research should focus on optimizing metrological practices to enhance quality and safety in healthcare.

RESUMO

Background: COVID-19 has led to significant global mortality, with Peru being among the countries most affected. While pre-existing comorbidities have been linked to most cases, the exact distribution of fatalities within the country remains unclear. We aimed to assess deaths attributed to cardiovascular diseases (CVD) before and during the COVID-19 pandemic across various regions and provinces in Peru. Methods: An observational georeferencing study was designed. Peru faced four waves of COVID-19 over three years, with variable impacts across its three regions (Coast, Highlands, and Jungle). Deaths related to cardiovascular diseases, such as heart failure (HF), arrhythmia, acute myocardial infarction (AMI), strokes, and acute coronary syndrome, were examined as primary variables. The study period spanned pre-pandemic years (2017-2019) and pandemic years (2020-2021), utilizing death data from the National Death Information System (SINADEF). The georeferencing analysis was conducted using ArcGIS v10.3. Results: A total of 28,197 deaths were recorded during the study period, with significant increases during the pandemic (2020-2021). Cardiovascular deaths were disproportionately higher during the pandemic, totaling 19,376 compared to 8,821 in the pre-pandemic period (p < 0.001). AMI and HF were the leading causes of mortality, showing significant increases from the pre-pandemic (5,573 and 2,584 deaths) to the pandemic period (12,579 and 5,628 deaths), respectively. Deaths due to CVD predominantly affected individuals aged over 60, with significant increases between the two study periods (7,245 vs. 16,497 deaths, p = 0.002). Geospatial analysis revealed regional disparities in CVD mortality, highlighting provinces like Lima and Callao as COVID-19 critical areas. The substantial increase in cardiovascular deaths during the COVID-19 pandemic in Peru showed distinctive patterns across regions and provinces. Conclusions: Geospatial analysis identified higher-risk areas and can guide specific interventions to mitigate the impact of future health crises. Understanding the dynamic relationship between pandemics and cardiovascular health is crucial for effective public health strategies.

RESUMO

The COVID-19 pandemic has increased stress levels in the population due to radical lifestyle changes caused by containment measures. Studies suggest that high levels of stress may be related to the development of irritable bowel syndrome (IBS). This study aims to explain how quarantine habits and lifestyles acted as risk factors for the frequency of this syndrome during the COVID-19 pandemic. An observational study was conducted with 34 Chilean participants (average age 24.5 ± 3.85 years), of whom 21 (62%) were female. Surveys on consumption trends and lifestyles created by the authors were administered. Additionally, we used the global physical activity questionnaire (GPAQ) and the depression anxiety stress scales (DASS-21) to assess psychological stress and the Rome IV criteria to assess IBS. Significant differences were found between individuals with better healthy habits compared to those with poor healthy habits. The former showed lower sedentary activity (32%, p = 0.005), only 27% were fast eaters (vs. 44%, p = 0.001), had shorter nap intervals (14% vs. 28%, p = 0.03), and higher vegetable consumption (p = 0.02). There were 20 cases (59%) of IBS, with a strong association with the female sex (p = 0.004), where females were 15 times more likely to develop it compared to males (p = 0.008). Additionally, when alcohol consumption was added to females, there was a higher likelihood of developing this syndrome (p = 0.009), as individuals who consumed alcohol were 12 times more likely to develop it compared to those who did not (p = 0.02). Among other factors, it was observed that 57% of those with the syndrome consumed drinks more often (p = 0.02) but consumed fewer nuts (p = 0.009). In conclusion, IBS has a multifactorial etiology, and correcting individual habits such as alcohol consumption could potentially prevent or delay its development. Therefore, it is important to maintain healthy lifestyles, regardless of non-modifiable factors such as gender, in order to better cope with this syndrome.

RESUMO

Objective: Funeral practices have undergone significant changes during the COVID-19 pandemic. Thus, the death of a family member from this disease has altered the typical course of the bereavement process. Therefore, this study seeks to determine the relationship between the levels of grief, anxiety, and depression in relatives of patients who died from COVID-19 in Peru. Methods: A total of 250 volunteers were obtained, but after applying the inclusion criteria and not being able to contact five of them, the sample consisted of 115 participants over 18 years of age who lost a family member to COVID-19 between 2020 and 2021. They developed the Prolonged Grief Questionnaire-13 and the Zung Anxiety and Depression Questionnaires, in virtual surveys using Google FormTM (Google, CA). Results: Our analysis revealed that all cases of anxiety (18.3%) were present in individuals experiencing prolonged grief (76.5%), while 49.5% (57/115) of participants exhibited symptoms of depression. Furthermore, we identified a significant association between prolonged grief and both anxiety (p = 0.005) and depression (p < 0.001). Prolonged grief predominantly affected females (45.2%) and individuals aged 31-40 years (28.7%) (p < 0.001). Regarding predictors of anxiety symptoms, we found that both age group (p = 0.035) and grief (p < 0.001) played significant roles. Gender (p = 0.019) and grief (p < 0.001) emerged as predictors of depression, while gender alone predicted grief in relatives of individuals who succumbed to COVID-19 (p = 0.019). Conclusion: Our results suggest a clear association between prolonged grief and mental health issues among relatives of COVID-19 patients who have passed away. Consequently, it is imperative to provide comprehensive psychological and spiritual support throughout the grieving process, aiming to mitigate the negative impact of traumatic events.

RESUMO

Introduction and objective: The COVID-19 pandemic has caused mental health problems worldwide. Older people have been particularly affected by the lockdown as their health conditions have changed, although they have been kept in isolation to avoid exposure to contagion. We sought to determine the association between lifestyles and anxiety in older adults during the COVID-19 pandemic. Materials and methods: This study was cross-sectional. We enrolled 150 older adults of both sexes and with a history of chronic diseases from the municipality of El Agustino (Lima, Peru). The 20-item Geriatric Anxiety Scale and the 25-item Lifestyle Questionnaire on eating, physical activity, rest, and sleep were administered in Spanish during July-August 2021. Results: The mean age was 70.8 ± 8.1 years, 54.7% were male, and 75.3% practiced exercise. During the COVID-19 pandemic, 99.3% of the elderly had healthy lifestyles and 40% presented anxiety (mild, moderate, and severe anxiety in 26.7%, 8.7%, and 4.7%, respectively). We found no association between anxiety and lifestyle (p = 0.189), physical exercise was a predictor of lifestyle (p < 0.001) and we did not find predictors of anxiety symptoms (p > 0.05). Conclusions: Our results suggest that there was no link between anxiety symptoms and lifestyle in older adults during the lockdown. It is important to conduct in-depth research on factors associated with anxiety symptoms among older residents in other regions, focusing on population groups with the highest rates of infection and death from COVID-19.

RESUMO

BACKGROUND/AIMS: Athletes are susceptible to oral injuries. To reduce the incidence and severity of oral trauma, a custom-made mouthguard, a device positioned in the mouth to prevent damage to teeth and surrounding structures, is recommended. In field hockey, according to the international rules of this sport, using mouthguards is not mandatory, but it is recommended to wear them at all times while practicing this discipline. We aimed to determine characteristics and differences regarding mouthguard usage among field hockey players from different countries participating in the XII ODESUR Games. METHODS: We conducted a cross-sectional study that included 78 voluntary hockey athletes that met the inclusion criteria. The questionnaire used was validated by Panam Sports, collecting information on the type of mouthguard (custom-made or prefabricated), and the time of use of the mouthguard (range of 5 years). RESULTS: Of the total number of athletes, 96% used mouthguards, of which 64% were custom-made type, and 32% were prefabricated (p < .001). Custom-made mouthguards were used by 100%, 89%, and 64% of athletes in Argentina, Chile, and Peru, respectively, while only 40% of athletes in Paraguay and Uruguay used them. It has also been observed that more than 50% of the individuals have not controlled and replaced their intraoral devices for more than 10 years. CONCLUSIONS: Our results reveal a problem with a public health dimension and thus invite the standardization of guidelines with an educational approach to promoting and adopting good sports practices. This report is the first on using mouthguards in high-performance athletes during an international multisport event.

RESUMO

Background: Empathy in healthcare service refers to the ability of healthcare workers (HCWs) to put themselves in patients' shoes, which is necessary to ensure a good physician-patient relationship and provide quality care. Various studies have shown that empathy varies depending on the country, the instrument used, the evaluator, and the HCW's specialty. This systematic review aims to estimate the levels of empathy among HCWs in South American countries between 2000 and 2019. Methods: We conducted searches in 15 databases (PubMed, Scopus, Web of Science, EMBASE, Scielo, PsycoInfo, ScientDirect, Latindex, and LILIACS), four preprint servers (medRxiv, bioRxiv, SportRxiv, and Preprints), and other search engines such as Dimensions (20), Google Scholar, Yahoo!, and Alicia CONCyTec (c). We followed the PRISMA guidelines, and this study was registered in PROSPERO (CRD42023454007). Results: Out of 18,532 documents identified from November 10 to 28, 2021, 10 articles were included (n = 2,487 participants, of which 1989 were patients). Among the studies focusing on self-evaluated empathy, four relied on the Jefferson Scale of Empathy for medical professionals (JSE-HP). However, assessments from patients employing Jefferson Scale of Patient's Perceptions of Physician Empathy (JSPPPE) and Consultation and Relational Empathy (CARE) scale suggested high levels of empathy We found that both professionals and patients perceived that empathic care was provided, often at a medium or regular level. Surgery residents presented lower levels of empathy compared to obstetrics-gynecology and pediatrics physicians. Conclusion: Empathy is crucial in determining the quality of care and patient satisfaction during healthcare services provided by HCWs. Therefore, it is important to support professionals so that the various stressful situations they encounter in their work and daily life do not negatively influence the approach they provide to patients.

RESUMO

Background: Diabetic foot is one of the most significant complications in individuals with diabetes and is closely associated with lower limb amputation. The antibiotic susceptibility patterns of these bacterial isolates play a critical role in guiding effective treatment strategies We aimed to determine the most common bacterial agents causing diabetic foot infections in a tertiary-care hospital in Peru. Methods: Clinical and microbiological data were collected from 181 patients diagnosed with diabetic foot infections and positive microbiological culture results. All the samples were analyzed with the Vitek 2 compact system and the cut-off points were defined with the CLSI M100 guide. The data were segregated based on mono-microbial or poly-microbial cultures, bacterial types, and antibiotic susceptibility profiles. Results: A total of 32 bacterial species were identified, predominantly Gram-negative (63%). The most frequent bacterial agents isolated were Staphylococcus aureus (19.9%), Escherichia coli (12.2%), Pseudomonas aeruginosa (8.3%), and Proteus vulgaris (6.6%). These bacteria commonly exhibited resistance to Ampicillin, Ciprofloxacin, Levofloxacin, Trimethoprim-sulfamethoxazole, and Cefuroxime. E. coli showed the highest antibiotic resistance (19 antibiotics), while Gentamicin, Tobramycin, and Levofloxacin demonstrated the highest sensitivity against the most prevalent bacteria. Gram-negative bacteria also exhibited notable antibiotic-susceptibility to Meropenem, Piperacillin/tazobactam, and Amikacin. Regarding the presence of Extended-Spectrum Beta-Lactamase, 54 isolates tested positive, with 35 (64.8%) and 14 (42.4%) of these being S. aureus and E. coli. Conclusions: Bacterial agents causing diabetic foot infections pose a constant concern, particularly due to the increasing antibiotic resistance observed. This difficulty in treating the condition contributes to a higher risk of amputation and mortality. Further research on bacterial susceptibility is necessary to determine appropriate dosages for pharmacological treatment and to prevent the overuse of antibiotics.

RESUMO

The rapid spread of SARS-CoV-2 has led to changes in every aspect of life and death. In Peru, where the longest quarantine has occurred with suboptimal results, the rituals have been turned around, impacting the relatives in multiple aspects. Here, we used a qualitative approach to analyze unresolved grief, hygiene changes, and stigma through semi-structured, online (Google Meet) interviews with 15 participants aged 20-72, who had lost family members to COVID-19. The recorded and transcribed interviews were analyzed using reflexive thematic analysis. Most participants had unresolved grief due to the blocking of funeral rituals, which could predispose them to prolonged mourning. After the loss of relatives, hygiene measures will be improved to avoid infections and new deaths in every family, while most participants felt no stigma in their milieu, since their relatives accompanied them during the funeral, supporting them from afar. It is important that interventions are implemented to prevent the progression of grief by providing mental health opportunities for the bereaved.

RESUMO

Objectives: The Papanicolaou's (Pap's) stain is used for cervical cancer screening. It employs toxic-carcinogenic expensive reagents, which may not be easily accessible to many communities worldwide. The objective of this study was to validate the grape-based alcohol-extracted dye (Vinatela) on normal cervical samples for the Pap test. Material and Methods: Samples of the two grape species were collected from two vineyards through the Agroindustrial Research Institute of Universidad Privada San Juan Bautista. The dye extraction from the grape species and the dye performance to stain cells were conducted in three phases: (a) direct staining with pre-fermentation wine products, (b) direct fragmentation of grapes and direct staining with shells of the grapes, and (c) alcoholic extraction of the dye. Vinatela obtained from two species (Vitis vinifera "Tempranillo" and "Malbec") and posterior staining of cervical samples. We conducted a double-blind validation on 30 cervical samples. Results: The basophilic components of the cervical cells were stained. Alcoholic extraction staining protocol had a low yield. The nuclear and cytoplasmic borders, the nuclear details, and the polymorphonuclear nuclei were stained with Vinatela and could be differentiated during nuclear coloration. The initial staining protocol was 10- 20 min × (mean ~12 min) staining time. We noted a slightly better staining with V. v. Tempranillo as compared to V. v. Malbec (P = 0.045). Conclusion: Cervical cells stained with Vinatela stain from two grape species cultivated in the Southern of Peru, showed basophilic nuclear details.
