Detection through the use of RT-MqPCR of asymptomatic reservoirs of malaria in samples of patients from the indigenous Comarca of Guna Yala, Panama: Essential method to achieve the elimination of malaria.

BACKGROUND: Plasmodium vivax is the main causative agent of malaria in Panama. However, the prevalence of asymptomatic infections in the different endemic regions remains unknown. Understanding the epidemiological behavior of asymptomatic infections is essential for the elimination of malaria. This study aimed to determine the prevalence of asymptomatic malarial infections in one of the main endemic regions of Panama using multiplex real-time reverse transcription RT-MqPCR. METHODS: A cross-sectional study was conducted in three communities in the Guna Yala Comarca. A total of 551 thick blood smears and their respective samples on filter paper were collected from volunteers of different ages and sexes from June 20 to 25, 2016. Infections by the Plasmodium spp. were diagnosed using microscopy and RT-MqPCR. All statistical analyses were performed using the R software. RESULTS: The average prevalence of asymptomatic infections by P. vivax in the three communities detected by RT-MqPCR was 9.3%, with Ukupa having the highest prevalence (13.4%), followed by Aidirgandi (11.1%) and Irgandi (3.3%). A total of 74 samples were diagnosed as asymptomatic infections using RT-MqPCR. Light microscopy (LM) detected that 17.6% (13/74) of the asymptomatic samples and 82.4% (61/74) were diagnosed as false negatives. A 100% correlation was observed between samples diagnosed using LM and RT-MqPCR. A total of 52.7% (39/74) of the asymptomatic patients were female and 85.1% (63/74) were registered between the ages of 1 and 21 years. Factors associated with asymptomatic infection were community (aOR = 0.38 (95% CI 0.17-0.83), p < 0.001) and age aOR = 0.98 (95% CI 0.97-1.00), p < 0.05); F = 5.38; p < 0.05). CONCLUSIONS: This study provides novel evidence of the considerable prevalence of asymptomatic P. vivax infections in the endemic region of Kuna Yala, representing a new challenge that requires immediate attention from the National Malaria Program. The results of this study provide essential information for the health authorities responsible for developing new policies. Furthermore, it will allow program administrators to reorient and design effective malaria control strategies that consider asymptomatic infections as a fundamental part of malaria control and move towards fulfilling their commitment to eliminate it.

Effectiveness and chemical insights: Exploring interactions between nanomicelles and monoterpenoids for head lice treatment.

This study evaluates the pediculicidal activity of nanoformulations containing different binary essential oil component mixtures (eugenol:linalool, 1,8 -cineole:linalool, and eugenol:thymol) using immersion bioassays. These have allowed us to evaluate the knockdown time affecting 50% of the individuals (KT50). In addition, the type of interaction between the components in each mixture was established in terms of the combination index (IC). The KT50 values were 6.07; 8.83; 7.17 and 27.23 h for linalool, 1,8 -cineole, eugenol, and thymol, respectively. For the eugenol:linalool mixtures, the efficacy was lower or equal to that obtained for the nanoformulations of the pure compounds, with values of KT50 about 13.33, 8.16 and 6.71 h for mixtures with ratios 3:1, 1:1 and 1:3, respectively. These mixtures present IC > 1, evidencing antagonistic interaction, which is enhanced with eugenol content. In the case of the binary mixtures of 1,8 -cineole: linalool, KT50 values were similar to those obtained for eugenol:linalool mixtures with similar ratios. In this case, IC assumes values close to unity, suggesting additive interactions independently of the mixture composition. On the other side, mixtures of eugenol:thymol with 1:1 and 1:3 ratios showed values of 9.40 and 32.93 h, while the mixture with a 3:1 ratio showed the greatest effectiveness (KT50 of 4.42 h). Eugenol:thymol mixtures show synergistic interaction (IC < 1) for combinations 3:1 and 1:1, while no interaction was observed for 1:3 combination. This indicates that eugenol enhances thymol activity. These results must be considered an important step forward to the development of effective pediculicidal nanoformulations based on botanical compounds.

Nurses' perceived barriers and facilitators to the implementation of nurse prescribing: Delphi study and focus group.

AIM: To obtain consensus on barriers and facilitators to nurse prescribing following its recent introduction in Spain. DESIGN: A three round online Delphi survey and focus group. METHODS: An exploratory method was used with three consecutive rounds of questionnaires based on anonymity and feedback, and a focus group. The study was carried out with primary care, specialized care, socio-health care and manager nurses. RESULTS: On the basis of the Delphi study that was conducted, a list of 15 barriers and 18 facilitators of nurse prescribing was obtained. However, no general consensus was found with respect to the prioritization of these barriers/facilitators. The analysis of the results of the focus group confirmed the information obtained from the Delphi study. The main barriers highlighted were dependence on the figure of the physician, insufficient training in pharmacology, a lack of institutional support and the limited list of products that could be prescribed. The key facilitators were academic knowledge and ongoing training and education, independence in the functions and responsibilities of the nursing profession, adaptation to new roles and autonomy in the case of chronic care processes. CONCLUSION: Nurses were generally positive about the introduction of nurse prescribing. The commitment of nurses to training and their accreditation as prescribers (internal forces) and health policy and nursing management (external forces) play a fundamental role in supporting the basis of nurse prescribing and ensuring that it is developed with the identified support resources, such as staff training and the provision of the materials necessary for its proper implementation, all with the aim of guaranteeing quality healthcare. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Strong models of nurse prescribing are being considered globally to address population needs. The results can help the future implementation of non-medical independent prescribing and provide guidance to the government and society on the interventions that can be used to consolidate it. IMPACT: What problem did the study address? By 2027, the world's population will receive more than 4.5 trillion doses of medicine each year. However, the WHO estimates a projected shortfall of 10 million health workers by 2030. Inadequacies with traditional physician-led care systems mean that new approaches are imperative to maintain patient access to prescription medicines, with NP being a key element in this regard. In Catalonia (Spain), the accreditation process for nurses as prescribers was implemented in 2021. It is therefore of vital importance to question and consult the nurses themselves, the main promoters of the process, to find out their perceptions and thus be able to take them into consideration in the implementation process. What were the main findings? A total of 15 barriers and 17 facilitators were identified. The main perceived barriers are dependence on the figure of the physician, insufficient training in pharmacology during undergraduate studies and a lack of institutional support. The main perceived facilitators are academic knowledge and ongoing education and training, independence in nursing functions and responsibilities, and adaptation to new roles and tasks. Where and on whom will the research have an impact? These results can contribute to improving NP implementation in Spain and serve as a reference for other countries, especially where NP education and training have only recently been instigated or are in the planning process. REPORTING METHOD: Standards for reporting qualitative research: a synthesis of recommendations. SRQR. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Adaptation, implementation, and evaluation of an online health sciences training program for brief smoking intervention: A pre-post study in four European countries.

BACKGROUND: Tobacco cessation intervention has a positive impact on quality of care. For health professionals, limited competency in this area may be associated with poor training during their academic programs. There is a clear need to further develop and implement training programs to improve tobacco cessation knowledge, skills, and attitudes among healthcare students. OBJECTIVES: The aim of this study was to assess the effectiveness of the innovative online training program "Brief Intervention in Smoking Cessation" for healthcare students to improve their knowledge, skills, and attitudes. DESIGN: A pre-post evaluation study with a satisfaction assessment tool was used. SETTING: Seven universities from four European countries, including Belgium, Portugal, Spain, and the United Kingdom, participated. PARTICIPANTS: One thousand and seventy-two (1072) undergraduate students participated, with 851 completing the online program. METHODS: All participants completed the "Brief Intervention in Smoking Cessation" online program, which consisted of five theoretical modules, five videos, and three virtual simulation cases between January 2020 and June 2022. Knowledge was assessed by a multiple-choice test, and practical skills were assessed by a simulation algorithm, both of which were developed by education and smoking cessation experts. Competency was achieved when students successfully completed both assessments. Satisfaction was measured using an ad hoc 16-item questionnaire. Pre-post changes in knowledge were assessed using a paired Student's t-test. RESULTS: Eighty-six percent of the students achieved smoking cessation competency. Students significantly improved their knowledge score on a scale of 0 to 10 points, with a mean pre-program score of 3.79 vs a mean post-program score of 7.33 ([-3.7 - -3.4] p < 0.001), acquiring sufficient attitudes and skills (simulation mean of 7.4 out of 10 points). Students were highly satisfied with the program (8.2 out of 10) and recommended it to other students (8.4 out of 10). CONCLUSIONS: The "Brief Intervention in Smoking Cessation" online training program is effective for the acquisition of smoking cessation competencies among European health profession students.

Placental and Doppler ultrasound findings in pregnant women with SARS-CoV-2 infection.

BACKGROUND: Several viral infections cause changes in the placenta. Cytomegalovirus, herpes viruses, and HIV cause increased placental thickness; Zika virus induces focal regions of necrosis; parvovirus B19 causes a structural injury. Umbilical flow can be considered a direct measurement of vascular placental function. OBJECTIVE: This study aimed to compare placental ultrasound and umbilical Doppler findings in pregnant women who tested positive or negative for SARS-CoV-2. Our work aimed to confirm the suspicion of placental infection and the consequence in fetal physiopathology. STUDY DESIGN: Fifty-seven pregnant women who tested positive for SARS-CoV-2 at the time of or 1 month before the ultrasound scan were evaluated. Cases included 9 first trimester, 16 second trimester, and 32 third trimester ultrasound scans. For comparison, 110 pregnant women (controls) were evaluated. They included 19 women in their first trimester, 43 in their second trimester, and 48 in the third trimester. Controls were asymptomatic and tested negative for SARS-CoV-2 infection in the last 72 hours before the ultrasound scan. Fetal biometry, placental thickness, placental lakes and Doppler umbilical vein parameters, including venous cross-sectional area (mean transverse diameter and radius of umbilical vein, mean velocity of umbilical vein), and umbilical vein blood flow were evaluated. RESULTS: Placental thickness (in millimeter) was significantly higher in the group of pregnant women with SARS-CoV-2 infection (53.82 [10-115]) than in the control group (33.82 [12-66]; P<.001) in their second and third trimesters. The frequency of >4 placental lakes was significantly higher in the group of pregnant women with SARS-CoV-2 infection (28/57 [50.91%]) than in the control (7/110 [6.36]; P<.001) in all 3 trimesters. The mean velocity of umbilical vein was significantly higher in the group of pregnant women with SARS-CoV-2 infection (12.45 [5.73-21]) than in the control group (10.81 [6.31-18.80]; P=.001) in all 3 trimesters. Umbilical vein blood flow (in milliliter per minute) was significantly higher in the group of pregnant women with SARS-CoV-2 infection (389.9 [6.52-1496.1]) than in the control group (305.05 [3.11-1441]; P=.05) in all 3 trimesters. CONCLUSION: Significant differences in placental and venous Doppler ultrasound were documented. Placental thickness, placental venous lakes, mean velocity of umbilical vein, and umbilical vein flow were significantly higher in the group of pregnant women with SARS-CoV-2 infection in all 3 trimesters.

Genetic footprints of a rapid and large-scale range expansion: the case of cyclic common vole in Spain.

In the Anthropocene, many species are rapidly shifting their ranges in response to human-driven habitat modifications. Studying patterns and genetic signatures of range shifts helps to understand how species cope with environmental disturbances and predict future shifts in the face of global environmental change. We investigated the genetic signature of a contemporary wide-range expansion observed in the Iberian common vole Microtus arvalis asturianus shortly after a colonization event. We used mtDNA and microsatellite data to investigate patterns of genetic diversity, structure, demography, and gene flow across 57 localities covering the historical range of the species and the newly colonized area. The results showed a genetic footprint more compatible with a true range expansion (i.e. the colonization of previously unoccupied areas), than with a model of "colonization from within" (i.e. local expansions from small, unnoticed populations). Genetic diversity measures indicated that the source population was likely located at the NE of the historical range, with a declining gradient of genetic diversity towards the more recently invaded areas. At the expansion front, we observed the greatest gene flow and smallest pairwise differences between nearby localities. Both natural landscape features (rivers) and recent anthropogenic barriers (roads, railways) explained a large proportion of genetic variance among populations and had a significant impact on the colonization pathways used by voles.

Physiotherapy in palliative medicine: patient and caregiver wellness.

OBJECTIVES: Despite the demonstrated efficacy of physiotherapy in palliative care programmes, there are scarce data of its real-life impact on patients' and caregivers' wellness and stress. Our aim was to assess effectiveness of a 30-day physiotherapy programme in psychological wellness and health-related quality of life (HRQoL) of patients with advanced chronic diseases or cancer and in their caregivers' stress. METHODS: Quasiexperimental before-after study applying personalised kinesitherapy, exercise with curative effects, respiratory physiotherapy, therapeutic massages and ergotherapy. Psychological wellness, HRQoL and caregiver's strain outcomes were measured. RESULTS: 207 patients (60% men, with a mean age of 73.6±12 years) were included; 129 (62.3%) with advanced cancer, and the remaining 78 with advanced chronic diseases. Psychological wellness (Emotional Stress Detection Tool decreased from 12.4±3 to 11±3; p<0.0001), caregiver's strain (Caregiver Strain Index decreased from 8.5±3.2 to 7.9±3.5; p<0.0001) and HRQoL (WHO-BREF physical health domain increased from 8.3±2.6 to 9.4±2.9; p<0.0001) showed a significant improvement after the physiotherapy programme. Global satisfaction with the physiotherapy intervention was also high (Client Satisfaction Questionnaire-8 of 28.3±3.3 points). CONCLUSIONS: A personalised physiotherapy programme incorporated to integral palliative care improved psychological wellness, HRQoL and caregivers' strain of patients with advanced chronic diseases and cancer.

Desenlaces obstétricos y perinatales en embarazadas con obesidad. Estudio de prevalencia / Obstetric and perinatal results in pregnant women with obesity. Prevalence study

Resumen OBJETIVO: Evaluar la prevalencia de obesidad en el área de influencia del Hospital Universitario Infanta Leonor y analizar los desenlaces obstétricos y perinatales de embarazadas obesas. MATERIALES Y MÉTODOS: Estudio observacional, transversal y retrospectivo efectuado con base en los datos de partos atendidos en el año 2019 en el Hospital Universitario Infanta Leonor y asentados en las historias clínicas. Se evaluaron y determinaron la prevalencia de obesidad, las variables maternas y el desenlace perinatal en embarazadas con obesidad. RESULTADOS: Se analizaron 428 embarazadas, con obesidad, de 2048 partos atendidos. La prevalencia de obesidad fue 21.59%. La edad materna fue 32 años y 39.10% eran migrantes; el índice de masa corporal (IMC) medio fue 33.61 kg/m2; 33.18% eran primíparas; 14.12% recibieron algún tratamiento y 18.63% seguimiento endocrinológico. Las semanas de embarazo al parto fueron 39; 43.93% de los partos se indujeron. La tasa de cesáreas fue 26.17% y en el 51.45% hubo complicaciones. El peso medio de los recién nacidos fue 3345.9 g. La mediana del Apgar al primer minuto fue 9 y 10 a los 5. El 16.24% de los recién nacidos tuvo pH en sangre de cordón ≤ 7.20; 1.96% de los recién nacidos ingresó a cuidados intensivos y 0.93% fue la tasa de muerte fetal. CONCLUSIONES: La prevalencia de obesidad fue superior a la media nacional. Factores como la migración y la multiparidad se asociaron con mayor IMC, y éste con más complicaciones (ingreso a cuidados intensivos y muerte fetal anteparto). La obesidad se asoció con mayor tasa de inducción de parto, cesáreas, desgarros perineales, peso fetal y menor pH al nacimiento.

Abstract OBJECTIVE: To evaluate the prevalence of obesity in the healthcare area of Hospital Universitario Infanta Leonor and analyze the obstetric and perinatal outcomes of obese patients. MATERIALS AND METHODS: This is a retrospective transversal observational study based on data from births in Hospital Universitario Infanta Leonor during 2019. 2048 clinical records were evaluated in order to determine prevalence of obesity, as well as maternal and perinatal outcomes variables in pregnant women with obesity. RESULTS: A total of 428 pregnant women with obesity were analyzed out of 2048 deliveries attended. The prevalence of obesity was 21.59%. Maternal age was 32 years; 39.10% of the patients were migrants; the mean BMI was 33.61 kg/m2; 33.18% were primiparous; 14.2% received any pharmacological treatment and 18.63% had endocrinological follow-up. Gestational age at labour was 39 weeks; 43.93% of deliveries were induced; caesarean delivery rate was 26.17% and 51.45% presented complications. Newborn's mean weight was 3345.9 g. The 1-minute Apgar score median was 9 and the 5-minute Apgar score was 10; 16.24% of newborns had cord pH≤7.20; 1.96% ICU admission and 0.93% of fetal death. CONCLUSIONS: The prevalence of obesity in pregnant women in the Hospital Universitario Infanta Leonor healthcare area was higher than the national mean. Factors such as migration and multiparity are associated with higher BMI, which leads to an increased risk of complications, especially ICU admission and antepartum fetal death. Obesity is associated with a higher rate of labour induction, caesarean delivery, tears, higher neonatal weight and lower pH.

Imported malaria in children in Alicante, Spain (1994-2019) / Malaria importada en población pediátrica de Alicante, España (1994-2019)

Introduction: In recent years there has been an increase in imported malaria among children in whom it is a potentially serious and fatal disease. Objective: To describe the incidence and the clinical and epidemiological characteristics of malaria in children diagnosed in Alicante, Spain, over a 26-year period. Materials and methods: We conducted an observational retrospective study of malaria in children aged under 15 years diagnosed at the Alicante General University Hospital from 1994 to 2019. Results: Twenty-four cases were registered over the study period. The frequency of cases increased from 2 over the first five years to 11 in the last five years. The median age of the children was 6 years (interquartile range: 3-8); 91.6% came from sub-Saharan Africa. Over half (n=15, 62.5%) were children born in Spain to immigrant parents visiting friends and relatives (VFR); just one (6.7%) had received antimalarial chemoprophylaxis. The most frequent clinical signs were fever (86.9%), hepatosplenomegaly (70.8%), and anemia (70.8%). Plasmodium falciparum was the most frequently identified species (83.3%, n=20). The most common treatment was oral piperaquine/dihydroartemisinin (41.6%, n=10) with favorable outcomes in all cases. Conclusions: Imported childhood malaria shows an increasing incidence and a nonspecific clinical presentation. Professional awareness of this disease and a high degree of clinical suspicion are needed for the early initiation of treatment. Pre-travel preventive measures should be promoted when appropriate.

Introducción. En los últimos años ha aumentado la malaria importada en niños, en quienes la enfermedad es potencialmente grave y mortal. Objetivo. Describir la incidencia y características clínico-epidemiológicas de niños con diagnóstico de conmalaria en Alicante, España, en los últimos años. Materiales y métodos. Se hizo un estudio observacional y retrospectivo de los casos de malaria en menores de 15 años, diagnosticados en el Hospital General Universitario de Alicante desde 1994 hasta 2019. Resultados. Se registraron 24 casos. El número de casos pasó de dos en el primer quinquenio a 11 en el último. La mediana de edad fue de 6 años (rango intercuartílico: 3 a 8). El 91,6 % procedía de África subsahariana. Los niños nacidos en España de padres inmigrantes que viajan a una zona endémica para visitar a familiares y amigos (Visiting Friends and Relatives) representaron el 62,5 % (n=15) y solo consta que recibiera quimioprofilaxis antipalúdica un paciente (6,7 %). Los signos clínicos más frecuentes fueron fiebre (86,9 %), hepatoesplenomegalia (70,8 %) y anemia (70,8 %). Plasmodium falciparum fue la especie más frecuentemente identificada (83,3 %; n=20). El tratamiento más empleado fue la combinación de dihidroartemisina y piperaquina por vía oral (41,6 %, n=10), con evolución favorable en todos los casos. Conclusiones. Los casos de paludismo infantil importado están aumentando en los últimos años. Las manifestaciones clínicas son inespecíficas en estos niños, por lo que es importante que los profesionales conozcan la enfermedad y tengan un alto índice de sospecha para iniciar el tratamiento precoz. Además, deben tomarse las medidas preventivas adecuadas antes de un viaje.

Diagnostic Concordance between the Visual Analogue Anxiety Scale (VAS-A) and the State-Trait Anxiety Inventory (STAI) in Nursing Students during the COVID-19 Pandemic.

Anxiety is one of the most common problems among nursing students. The State-Trait Anxiety Inventory (STAI) is used to detect anxiety in this population; however, its length hinders speedy detection. For this reason, a faster and more efficient instrument is needed for early detection. This study aimed to determine the relationship between the anxiety measurement scales State-Trait Anxiety Inventory (STAI) and the Visual Analogue Scale for Anxiety (VAS-A) by establishing a discrimination threshold through the contrast of true positive rates (VPR) and false positive rates (FPR). To this end, a cross-sectional quantitative observational and analytical study was carried out on 185 fourth-year nursing students. The data collected were anxiety (STAI and VAS-A) and socio-demographic variables during the COVID-19 pandemic. The results showed a correlation between the two scales (VAS-A and STAI). The VAS-A is a useful instrument for assessing students in a crisis that could potentially generate anxiety. The study established a reasonably safe error probability range (>5%), allowing the VAS-A scale to be used as a rapid diagnostic or pre-diagnostic tool, depending on the scores. The study shows that speedy detection of anxiety using the VAS-A and an in-depth approach with the STAI by teaching staff in crises is possible.

Weasel exposure to the anticoagulant rodenticide bromadiolone in agrarian landscapes of southwestern Europe.

Bromadiolone is an anticoagulant rodenticide (AR) commonly used as a plant protection product (PPP) against rodent pests in agricultural lands. ARs can be transferred trophically to predators/scavengers when they consume intoxicated live or dead rodents. ARs exposure in weasels Mustela nivalis, small mustelids specialized on rodent predation, is poorly known in southern Europe. Moreover, in this species there is no information on bioaccumulation of AR diastereomers e.g., cis- and trans-bromadiolone. Trans-bromadiolone is more persistent in the rodent liver and thus, is expected to have a greater probability of trophic transfer to predators. Here, we report on bromadiolone occurrence, total concentrations and diastereomers proportions (trans- and cis-bromadiolone) in weasels from Castilla y León (north-western Spain) collected in 2010-2017, where bromadiolone was irregularly applied to control outbreaks of common voles Microtus arvalis mainly with cereal grain bait distributed by the regional government. We also tested variables possibly associated with bromadiolone occurrence and concentration, such as individual features (e.g., sex), spatio-temporal variables (e.g., year), and exposure risk (e.g., vole outbreaks). Overall bromadiolone occurrence in weasels was 22% (n = 32, arithmetic mean of concentration of bromadiolone positives = 0.072 mg/kg). An individual showed signs of bromadiolone intoxication (i.e., evidence of macroscopic hemorrhages or hyperaemia and hepatic bromadiolone concentration > 0.1 mg/kg). All the exposed weasels (n = 7) showed only trans-bromadiolone diastereomer in liver, whilst a single analyzed bait from those applied in Castilla y León contained trans- and cis-bromadiolone at 65/35%. Bromadiolone occurrence and concentration in weasels varied yearly. Occurrence was higher in 2012 (100% of weasels), when bromadiolone was widely distributed, compared to 2016-2017 (2016: 20%; 2017: 8.33%) when bromadiolone was exceptionally permitted. The highest concentrations happened in 2014 and 2017, both years with vole outbreaks. Our findings indicate that specialist rodent predators could be exposed to bromadiolone in areas and periods with bromadiolone treatments against vole outbreaks.

Social determinants of violence against women in Panama: results from population-based cross-sectional studies and a femicide registry.

BACKGROUND: We aimed to investigate the prevalence of violence against women (VAW) in Panama and its association with social determinants of health (SDH) and to estimate the femicide rates from 2014 to 2017. METHODS: Data were derived from three cross-sectional population-based studies. Logistic regression models were used to estimate the association between SDH and VAW, expressed as odds ratios (ORs) and 95% confidence intervals (CIs). Age-standardized femicide rates were estimated using data from the Public Ministry. RESULTS: Compared to the reference categories, women in the lowest quintile (Q) of income distribution (Q1: OR 4.0 [95% CI 1.4-11.7], Q2: OR 3.0 [95% CI 1.1-7.9]), divorced/separated women (OR 1.5 [95% CI 1.0-2.1]) and those in the age categories 25-33 y and 34-49 y (OR 1.9 [95% CI 1.2-3.1]) were more likely to have experienced violence in the past year. Indigenous ethnicity (OR 2.3 [95% CI 1.3-4.1]), age 15-19 y (OR 1.8 [95% CI 1.1-2.9]) and lowest education levels (very low: OR 4.7 [95% CI 1.4-15.5]; low: OR 4.5 [95% CI 1.4-14.6]) were associated with permissive attitudes towards violence. Indigenous (OR 2.7 [95% CI 1.3-6.1]), Afro-Panamanians (OR 3.1 [95% CI 1.3-7.6]) and education level (low: OR 2.5 [95% CI 1.2-4.9]; medium: OR 3.0 [95% CI 1.4-6.6]) were associated with physical/sexual intimate partner violence. Standardized adjusted femicide rates (×100 000) from 2015 to 2017 were 1.5, 0.9 and 0.8, respectively. CONCLUSIONS: Our findings highlight the importance of prevention programmes.

SARS-CoV-2 among the Potential Viral Triggers for Vogt-Konayagi-Harada Disease: First Case Report and Literature Review.

OBJECTIVE: To describe a case of Vogt-Koyanagi-Harada (VKH) disease associated with the novel coronavirus disease 2019 (COVID-19). MATERIALS AND METHODS: A retrospective review of patient records was carried out to obtain data for a case report. A literature review was conducted of cases of uveitis associated with COVID-19 reported to date. CASE DESCRIPTION: A 32-year-old Hispanic female presented with bilateral granulomatous panuveitis consisting of VKH disease 2 weeks after a clinical course of COVID-19. Both eyes presented with anterior uveitis and edematous hyperemic papilla with flame-shaped peripapillary hemorrhages, macula-off serous retinal detachments with subretinal fluid, and vitritis. A complete systemic work-up was performed to exclude infectious or inflammatory etiologies. Ocular inflammatory signs and systemic symptoms improved with corticosteroid and immunomodulatory therapy. CONCLUSION: SARS-CoV-2 can be a potential immunological trigger for VKH disease. Patients presenting with panuveitis and a history of a previous flu-like illness should raise clinical suspicion of the presence of SARS-CoV-2 in the context of the ongoing global pandemic.

MCF-7 Drug Resistant Cell Lines Switch Their Lipid Metabolism to Triple Negative Breast Cancer Signature.

Obesity and adipose tissue have been closely related to a poor cancer prognosis, especially in prostate and breast cancer patients. The ability of transferring lipids from the adipose tissue to the tumor cells is actively linked to tumor progression. However, different types of breast tumor seem to use these lipids in different ways and metabolize them in different pathways. In this study we have tracked by mass spectrometry how palmitic acid from the adipocytes is released to media being later incorporated in different breast cancer cell lines (MDA-MB-231, SKBR3, BT474, MCF-7 and its resistant MCF-7 EPIR and MCF-7 TAXR). We have observed that different lines metabolize the palmitic acid in a different way and use their carbons in the synthesis of different new lipid families. Furthermore, we have observed that the lipid synthesis pattern varied according to the cell line. Surprisingly, the metabolic pattern of the resistant cells was more related to the TNBC cell line compared to their sensitive cell line MCF-7. These results allow us to determine a specific lipid pattern in different cell lines that later might be used in breast cancer diagnosis and to find a better treatment according to the cancer molecular type.

Factores de riesgo asociados con la leishmaniasis cutánea en dos comunidades rurales de Panamá Oeste

Introducción: La leishmaniasis cutánea (LC) es una enfermedad zoonótica endémica en Panamá. Su agente causal son protozoarios del género Leishmania y la transmiten insectos flebotominos. Objetivo: Evaluar los factores de riesgos asociados con la LC y la diversidad de flebotominos en dos comunidades rurales de Panamá Oeste. Metodología: Se seleccionaron dos comunidades endémicas para LC: Trinidad de las Minas (TM), de alta incidencia y Las Pavas (LP), de baja incidencia. Los factores de riesgo asociados con la LC fueron evaluados mediante una encuesta aplicada a100 personas (TM: n=50; LP: n=50). Se colectaron flebotominos con trampas CDC durante tres noches consecutivas en temporada lluviosa y seca. Resultados: La mayoría de las personas confirmó conocer sobre la LC (TM: 96% y LP: 68%). No se encontraron diferencias significativas entre las características sociodemográficas, estructura de las viviendas, composición del peridomicilio y abundancia/diversidad de animales domésticos en ambas comunidades. El reporte de perezosos cercanos al peridomicilio fue mayor en TM (70%) vs LP (32%). La especie de flebotomino antropofílica más abundante durante la temporada seca fue Lutzomyia gomezi (TM: 40.1% y LP: 10.4%). Durante la temporada lluviosa fue Nyssomyia trapidoi (43.4%) en TM y Psychodopygus panamensis (75.7%) en LP. Las especies zoofílicas más comunes en ambas comunidades fueron Trichopygomyia triramula y Pressatia dysponeta. Conclusión: La mayor incidencia de LC en TM podría estar condicionada a su ecología montañosa, con una cobertura boscosa cercana más extensa y una mayor frecuencia de mamíferos reservorios silvestres. Se confirmó la presencia de vectores de LC en el peridomicilio de ambas comunidades. (provisto por Infomedic International)

Introduction: Cutaneous leishmaniasis (CL) is a zoonotic disease endemic in Panama. Its causal agent are protozoa of the genus Leishmania and is transmitted by phlebotomine sandflies. Objective: To evaluate the risk factors associated with CL and the diversity of phlebotomine sandflies in two rural communities in western Panama. Methodology: Two CL endemic communities were selected: Trinidad de las Minas (TM), with high incidence and Las Pavas (LP), with low incidence. The risk factors associated with CL were assessed by means of a survey applied to 100 people (TM: n=50; LP: n=50). Phlebotomine sandflies were collected with CDC traps during three consecutive nights in rainy and dry season. Results: The majority of people confirmed knowledge about CL (TM: 96% and LP: 68%). No significant differences were found between sociodemographic characteristics, housing structure, peridomicile composition and abundance/diversity of domestic animals in both communities. The report of sloths near the peridomicile was higher in TM (70%) vs LP (32%). The most abundant anthropophilic phlebotomine species during the dry season was Lutzomyia gomezi (TM: 40.1% and LP: 10.4%). During the rainy season it was Nyssomyia trapidoi (43.4%) in TM and Psychodopygus panamensis (75.7%) in LP. The most common zoophilic species in both communities were Trichopygomyia triramula and Pressatia dysponeta. Conclusion: The higher incidence of CL in TM could be conditioned to its mountainous ecology, with a more extensive nearby forest cover and a higher frequency of wild mammal reservoirs. The presence of CL vectors in the peridomicile of both communities was confirmed. (provided by Infomedic International)

Plasmodium vivax Genetic Diversity in Panama: Challenges for Malaria Elimination in Mesoamerica.

Panama and all nations within the Mesoamerican region have committed to eliminate malaria within this decade. With more than 90% of the malaria cases in this region caused by Plasmodium vivax, an efficient national/regional elimination plan must include a comprehensive study of this parasite's genetic diversity. Here, we retrospectively analyzed P. vivax genetic diversity in autochthonous and imported field isolates collected in different endemic regions in Panama from 2007 to 2020, using highly polymorphic markers (csp, msp-1, and msp-3α). We did the analysis using molecular techniques that are cost-effective for malaria molecular surveillance within Mesoamerica. Thus, we used molecular analyses that are feasible for malaria molecular surveillance within the region, and that can provide useful information for policy and decision making about malaria elimination. We also evaluated if haplotypes established by combining the genotypes found in these genes were associated with relevant epidemiological variables and showed structure across the transmission foci that have been observed in Panama. Ten different haplotypes were identified, some of them strongly associated with geographical origin, age, and collection year. Phylogenetic analysis of csp (central repeat domain) revealed that both major variant types (vk210 and vk247) were circulating in Panama. Variant vk247 was restricted to the eastern endemic regions, while vk210 was predominant (77.3%) and widespread, displaying higher diversity (14 alleles) and geographically biased alleles. The regional implications of these molecular findings for the control of P. vivax malaria to achieve elimination across Mesoamerica are discussed.

The perception of training and professional development according to nursing students as health workers during COVID-19: A qualitative study.

AIM: To explore the perception of education and professional development of final-year nursing students who carried out health relief tasks during the COVID-19 pandemic. BACKGROUND: The COVID-19 pandemic has led to a global health emergency. This situation has exacerbated the need for additional healthcare employees, forcing the Spanish government to incorporate volunteer nursing students as auxiliary health staff. DESIGN: A qualitative study framed in the constructivist paradigm. METHODS: Twenty-two students of nursing were recruited. A purposeful sampling was implemented until reaching saturation. A semi-structured interview as a conversational technique was used to collect information based on three dimensions: academic curriculum, disciplinary professional development, and patient care. Subsequently, a content analysis of the information was carried out. Three phases were followed in the data analysis process: theoretical, descriptive-analytical, and interpretive. The COREQ checklist was used to evaluate the study. RESULTS: The most important results are linked to the students' professional and academic preparation, how the nurses handled the pandemic situation and the characteristics of the COVID-19 patients. CONCLUSIONS: Students require training in order to offer holistic care to patients, adapted to the context. Participants highlight the importance of professional values and recognise a high level of competence and autonomy in nurses.

Natural malaria infection in anophelines vectors and their incrimination in local malaria transmission in Darién, Panama.

BACKGROUND: More than 85% of the malaria cases in Panama occur in poor, rural and indigenous regions like Darien Province. Vector diversity, infection rate and spatial distribution are important entomological parameters of malaria transmission dynamics. Their understanding is crucial for the development of effective disease control strategies. The objective of this study was to determine the composition of Anopheles species, their natural infection rate and their geographic distribution to better understand the malaria transmission dynamics in Darién, Panama. METHODS: Anophelines mosquitoes were captured during the rainy and dry season of 2016. We selected five communities where adult anophelines were collected using CDC light-traps, and through protective human-baited traps. Detection of natural infection and Plasmodium genotype were detected via nested PCR through the amplification of ssrRNA and the circumsporozoite protein gene (csp), respectively. RESULTS: A total of 1,063 mosquitoes were collected mosquitoes were collected for the detection of natural infection with Plasmodium spp. Nine Anophelines species were identified, with the predominant species being: An. (Nys.) darlingi (45.0%) and An. (Nys.) albimanus (42.6%). Natural infection in An. (Nys.) albimanus with P. vivax was detected in one mosquito pool from the community Pueblo Tortuga (0.6%), three from Marraganti (1.7%), two from Bajo Chiquito (1.1%) and three pools from Alto Playona 3 (1.7%). For An. (Nys.) darlingi mosquitoes, we detected seven positive pools from the community Bajo Chiquito (4.0%), two pools from Marraganti (1.1%) and two pools from Alto Playona (1.1%). The P. vivax allelic variant VK210 was detected in infected mosquitoes. CONCLUSION: The results from this study provide new information on the transmission dynamics associated with anophelines vectors in the Darién region. This is the first report of natural P. vivax infection in An. (Nys.) darlingi and its incrimination as a potential malaria vector in this region of Panama. Additional studies are necessary to expand our knowledge and determine crucial parameters in malaria transmission in Darién, which in turn will aid the National Malaria Program in attaining an adequate malaria control strategy towards malaria elimination.

Nursing interventions for perinatal bereavement care in neonatal intensive care units: A scoping review.

BACKGROUND: Despite technological advances and specialist training of neonatal teams, perinatal deaths still occur. Such events are traumatic experiences for the parents and increase the risk of pathological grieving. Nursing is one of the main sources of support. However, the important work of nurses in these situations is made more difficult by the lack of recognized strategies that can be implemented to assist parents and family members in the bereavement process. AIM: Identify nursing interventions to help parents of neonates admitted to neonatal intensive care units cope with perinatal loss. METHODS: A scoping review based on the methodological framework established by Arksey and O'Malley was used. A total of 327 relevant studies were identified through a bibliographic search in Pubmed, CINAHL Plus, APA PsycNET and Scopus between 2000 and 2019. The screening process included an initial analysis of the relevance of the abstract and, when required, an extensive review of the full paper. RESULTS: A total of 9 papers were finally selected which responded to the research question. All nine papers are from the USA and have different methodological characteristics. A number of effective interventions were identified, including legacy creation, support groups, family-centred accompaniment and follow-up, parental involvement in pre-mortem care, intergenerational bereavement programmes, and the use of technological and spiritual resources. CONCLUSION: In general, the scant evidence that is available about nursing interventions around perinatal bereavement care underlines the requirement to thoroughly assess the effectiveness of those that have already been designed and implemented. IMPLICATIONS FOR NURSING PRACTICE AND POLICY: This scoping review contributes to the potential implementation of effective interventions to deal with and help parents and family members cope with perinatal bereavement, with nursing staff as the main source of support and leading interventions which have family members in the care team. This review also makes a substantial contribution to the development of a practical and evidence-based clinical guide for nursing, with recommendations that can be adapted to effective quality care criteria. It is additionally intended to encourage visibility in health policies of care and attention to perinatal grief in neonatal intensive care units.
