Cancer Screening in Low- and Middle-Income Countries.

The worldwide cancer burden is growing, and populations residing in low- and middle-income countries (LMICs) are experiencing a disproportionate extent of this growth. Breast, colorectal, and cervical cancers are among the top 10 most frequently diagnosed malignancies, and they also account for a substantial degree of cancer mortality internationally. Effective screening strategies are available for all three of these cancers. Individuals from LMICs face substantial cost and access barriers to early detection programs, and late stage at diagnosis continues to be a major cause for cancer mortality in these communities. This chapter will review the epidemiology of breast, colorectal, and cervical cancers, and will explore prospects for improving global control through novel approaches to screening in cost-constrained environments.

Is erenumab an efficient alternative for the prevention of episodic and chronic migraine in Spain? Results of a cost-effectiveness analysis.

BACKGROUND: The reimbursement of erenumab in Spain and other European countries is currently restricted because of the cost of this novel therapy to patients with migraine who have experienced previous failures to traditional preventive treatments. However, this reimbursement policy should be preferably based on cost-effectiveness studies, among other criteria. This study performed a cost-effectiveness analysis of erenumab versus topiramate for the prophylactic treatment of episodic migraine (EM) and versus placebo for chronic migraine (CM). METHODS: A Markov model with a 10-year time horizon, from the perspective of the Spanish National Healthcare System, was constructed based on data from responder and non-responder patients. A responder was defined as having a minimum 50% reduction in the number of monthly migraine days (MMD). A hypothetical cohort of patients with EM with one or more prior preventive treatment failures and patients with CM with more than two treatment failures was considered. The effectiveness score was measured as an incremental cost per quality-adjusted life year (QALY) gained and cost per migraine day (MD) avoided. Data from clinical outcomes and patient characteristics were obtained from erenumab clinical trials (NCT02066415, STRIVE, ARISE, LIBERTY and HER-MES). Deterministic and probabilistic sensitivity analyses were performed to validate the robustness of the model. RESULTS: After a 10-year follow-up, the estimated QALYs were 5.88 and 6.11 for patients with EM treated with topiramate and erenumab, respectively. Erenumab showed an incremental cost per patient of €4,420 vs topiramate. For CM patients, erenumab resulted in 0.756 QALYs gained vs placebo; and an incremental cost of €1,814. Patients treated with erenumab achieved reductions in MD for both EM and CM (172 and 568 MDs, respectively). The incremental cost per QALY gained with erenumab was below the Spanish threshold of €30,000/QALY for both health and societal perspectives (EM €19,122/QALY and CM €2,398/QALY). CONCLUSIONS: Erenumab is cost-effective versus topiramate as a preventive treatment for EM and versus placebo for patients with CM from the perspective of the Spanish National Health System.

[Initial assessment of immigrant patients in primary care]. / Atención inicial al paciente inmigrante en atención primaria.

The clinical interview of immigrant patients requires cultural competence to ensure good understanding and correct communication, in addition to collecting specific information that differs from that of native patients, such as origin and migratory route or cultural identity. Screening for latent tuberculosis infection is recommended in certain cases and screening for other infections, both cosmopolitan with a higher prevalence in migrants (HIV, syphilis, hepatitis B and C) and imported (Chagas, intestinal parasites, strongyloidiasis, schistosomiasis), depending on origin. It is essential to check the vaccination status and complete the vaccination schedule, adapting it to the current calendar, prioritizing vaccines such as measles, rubella and poliomyelitis. We propose preventive activities to be carried out when traveling to countries of origin, due to their special characteristics and risks: general advice, exploring the risk of malaria, assessing specific vaccinations, advice regarding sexually transmitted infections and special considerations if they have chronic diseases; and addressing, if appropriate, the risks of female genital mutilation.

Influence of income on in-hospital mortality in older adults during the first wave of the COVID-19 pandemic: results from the EDEN-33 study. / Influencia de la renta económica en la mortalidad intrahospitalaria de las personas mayores durante la primera ola de la pandemia por COVID-19: resultados del estudio EDEN-33.

OBJECTIVES: To determine whether income was associated with unexpected in-hospital mortality in older patients treated in Spanish public health system hospital emergency departments. MATERIAL AND METHODS: Fifty-one public health system hospital emergency departments in Spain voluntarily participated in the study. Together the hospitals covered 25% of the population aged 65 years or older included in all patient registers during a week in the pre-pandemic period (April 1-7, 2019) and a week during the COVID-19 pandemic (March 30 to April 5, 2020). We estimated a patient's gross income as the amount published for the postal code of the patient's address. We then calculated the standardized gross income (SGI) by dividing the patient's estimated income by the mean for the corresponding territory (Spanish autonomous community). The existence and strength of an association between the SGI and in-hospital mortality was evaluated by means of restricted cubic spline (RCS) curves adjusted for 10 patient characteristics at baseline. Odds ratios (ORs) for each income level were expressed in relation to a reference SGI of 1 (the mean income for the corresponding autonomous community). We compared the COVID-19 and pre-pandemic periods by means of first-order interactions. RESULTS: Of the 35 280 patients attended in the 2 periods, gross income could be ascertained for 21 180 (60%), 15437 in the pre-pandemic period and 5746 during the COVID-19 period. SGIs were slightly higher for patients included before the pandemic (1.006 vs 0.994; P = .012). In-hospital mortality was 5.6% overall and higher during the pandemic (2.8% pre-pandemic vs 13.1% during COVID-19; P .001). The adjusted RCS curves showed that associations between income and mortality differed between the 2 periods (interaction P = .004). Whereas there were no significant income-influenced differences in mortality before the pandemic, mortality increased during the pandemic in the lowest-income population (SGI 0.5 OR, 1.82; 95% CI, 1.32-3.37) and in higher-income populations (SGI 1.5 OR, 1.32; 95% CI, 1.04-1.68, and SGI 2 OR, 1.92; 95% CI, 1.14-3.23). We found no significant differences between patients with COVID-19 and those with other diagnoses (interaction P = .667). CONCLUSION: The gross income of patients attended in Spanish public health system hospital emergency departments, estimated according to a patient's address and postal code, was associated with in-hospital mortality, which was higher for patients with the lowest and 2 higher income levels. The reasons for these associations might be different for each income level and should be investigated in the future.

OBJETIVO: Determinar si el nivel económico durante la primera ola pandémica tuvo una influencia diferente a la esperable en la mortalidad intrahospitalaria de los pacientes mayores atendidos en los servicios de urgencias (SU) de los hospitales públicos españoles. METODO: Cincuenta y un SU públicos españoles que participaron voluntariamente y que dan cobertura al 25% de la población incluyeron todos los registros de pacientes de edad 65 años atendidos durante una semana del periodo preCOVID (1-4-2019 a 7-4-2019) y una semana del periodo COVID (30-3-2020 a 5-4-2020). Se identificó la renta bruta (RB) asignada al código postal de residencia de cada paciente y se calculó la RB normalizada (RBN) dividiendo aquella por la RB media de su comunidad autónoma. La existencia y fuerza de la relación entre RBN y mortalidad intrahospitalaria se determinó mediante curvas spline cúbicas restringidas (SCR) ajustadas por 10 características basales del paciente. Las OR para cada situación económica se expresó en relación con una RBN de 1 (referencia, renta correspondiente a la media de la comunidad autónoma). La comparación entre periodo COVID y no COVID se realizó mediante el estudio de interacción de primer grado. RESULTADOS: De los 35.280 registros de pacientes atendidos en ambos periodos, se disponía de la RB en 21.180 (60%): 15.437 del periodo preCOVID y 5.746 del periodo COVID. La RBN de los pacientes incluidos fue discretamente superior en el periodo preCOVID (1,006 versus 0,994; p = 0,012). La mortalidad intrahospitalaria fue del 5,6%, y fue superior durante el periodo COVID (2,8% versus 13,1%; p 0,001). Las curvas SCR ajustadas mostraron una asociación entre nivel económico y mortalidad diferente entre ambos periodos (p interacción = 0,004): en el periodo preCOVID no hubo diferencias significativas de mortalidad en función de la RBN, mientras que en el periodo COVID la mortalidad se incrementó en rentas bajas (OR = 1,82, IC 95% = 1,32-3,37 para RBN de 0,5) y en rentas altas (OR = 1,32, IC 95% = 1,04-1,68 y OR = 1,92, IC 95% = 1,14-3,23 para RBN de 1,5 y 2, respectivamente), sin diferencias significativas entre pacientes con COVID y con otros diagnósticos (p interacción = 0,667). CONCLUSIONES: Durante la primera ola de la pandemia COVID, la RB asignada al código postal de residencia de los pacientes atendidos en los SU públicos españoles se asoció con la mortalidad intrahospitalaria, que aumentó en pacientes de rentas bajas y altas. Las razones de estas asociaciones pueden ser distintas para cada segmento económico y deben ser investigadas en el fututo.

Exploring a Low-Cost Valorization Route for Amazonian Cocoa Pod Husks through Thermochemical and Catalytic Upgrading of Pyrolysis Vapors.

Ecuador as an international leader in the production of cocoa beans produced more than 300 000 tons in 2021; hence, the management and valorization of the 2 MM tons of waste generated annually by this industry have a strategic and socioeconomic value. Consequently, appropriate technologies to avoid environmental problems and promote sustainable development and the bioeconomy, especially considering that this is a megadiverse country, are of the utmost relevance. For this reason, we explored a low-cost pyrolysis route for valorizing cocoa pod husks from Ecuador's Amazonian region, aiming at producing pyrolysis liquids (bio-oil), biochar, and gas as an alternative chemical source from cocoa residues in the absence of hydrogen. Downstream catalytic processing of hot pyrolysis vapors using Mo- and/or Ni-based catalysts and standalone γ-Al2O3 was applied for obtaining upgraded bio-oils in a laboratory-scale fixed bed reactor, at 500 °C in a N2 atmosphere. As a result, bimetallic catalysts increased the bio-oil aqueous phase yield by 6.6%, at the expense of the organic phase due to cracking reactions according to nuclear magnetic resonance (NMR) and gas chromatography-mass spectrometry (GC-MS) results. Overall product yield remained constant, in comparison to pyrolysis without any downstream catalytic treatment (bio-oil ∼39.0-40.0 wt % and permanent gases 24.6-26.6 wt %). Ex situ reduced and passivated MoNi/γ-Al2O3 led to the lowest organic phase and highest aqueous phase yields. The product distribution between the two liquid phases was also modified by the catalytic upgrading experiments carried out, according to heteronuclear single-quantum correlation (HSQC), total correlation spectroscopy (TOCSY), and NMR analyses. The detailed composition distribution reported here shows the chemical production potential of this residue and serves as a starting point for subsequent valorizing technologies and/or processes in the food and nonfood industry beneficiating society, environment, economy, and research.

Pharmaceutically active compounds (PhACs) in surface water: Occurrence, trends and risk assessment in the Tagus River Basin (Spain).

In this study, the presence of 23 pharmaceutically active compounds (PhACs) including antibiotics, analgesics, anti-inflammatories, psychiatric and cardiovascular drugs, antifungals and metabolites was investigated in surface waters. A total of 89 samples were collected during 3 years (2020, 2021 and 2022) from a European representative river basin (Tagus, Spain). To elucidate PhAC potential sources, sampling points located in areas with low, median and high anthropogenic influence were selected. The analytical method based on solid phase extraction (SPE) followed by UHPLC-MS/MS analysis was validated meeting SANTE/2020/12830 and SANTE/12682/2019 performance criteria. PhACs were quantified above limits of quantification (LOQs) in 96 % of water samples, being the antihypertensives valsartan (648 ng/L, 87 % quantification frequency) and irbesartan (390 ng/L, 75 %) and the antidepressant o-desmethylvenlafaxine (495 ng/L, 76 %) the predominant pollutants. The rest of the target PhACs showed median concentrations between 4 and 172 ng/L with quantification frequencies ranging from 35 to 75 %. ∑PhAC concentrations did not show temporal or seasonal trends. However, valsartan and naproxen presented lower levels in drier (spring and summer) compared to the wetter. Source identification revealed a clear anthropogenic origin since concentrations obtained in highly populated areas were statistically higher (p < 0.01) than those quantified in sparsely populated ones. This finding was also confirmed by calculating PhACs mass flow rates, which ranged between 1.4 and 235 kg/y. Finally, data generated were used to estimate the potential risk to the aquatic ecosystem for three trophic levels (phototrophic, invertebrate and vertebrate organisms). Risk quotient ratios (RQs) were calculated for all PhACs at the median (P50) and worst-case (max) scenarios. Up to 7 PhACs (acetaminophen, carbamazepine, gemfibrozil, ibuprofen, irbesartan, ketoprofen and venlafaxine) showed high risk for the highest trophic level (fish) in >45 % of investigated locations.

Return to work after sick leave due to musculoskeletal disorder or injury: a longitudinal study conducted in Brazil.

BACKGROUND: Musculoskeletal disorders and injuries (MSDI) are conditions that affect the locomotor system characterized by pain and impairment of functionality. They are the leading cause of years lived with disability. The aim of this study was to analyze the factors that influence the return to work (RTW) among workers on sick leave due to MSDI.   METHODS: A longitudinal study was conducted in the city of São Paulo, Brazil, between 2020-2022. The participants were 216 workers who required social security compensation due to MSDI. They filled out online questionnaires about their sociodemographic characteristics, health risk behaviors, work characteristics and health conditions. They were followed for 365 days after their first day of sick leave. A Cox regression was performed to identify the factors that influenced their first RTW. RESULTS: Most participants were male (53.0%), mean age was 39.5 years (SD 10.6), 70.4% returned to work within the one-year follow-up period. The mean duration of sick leave was 192.6 days. Factors associated with a lower RTW were age 40 years and older (HR 0.54; 95%CI 0.39-0.76) and the interaction between perceptions of the need for improvement in the physical and psychological domains of quality of life (HR 0.67; 95%CI 0.48-0.94). CONCLUSIONS: Occupational healthcare professionals should pay greater attention to patients who are aging and those with perceived worse physical and psychological conditions, in order to facilitate the reintegration process and promote sustained RTW after sick leave due to musculoskeletal disorder or injury.

Material and methods: Descriptive study carried out in patients diagnosed with CHD in a second level hospital of the Mexican Social Security Institute (IMSS) in Puebla, Mexico during the period 2016-2017. Records of full-term newborns (NB) up to 14 years of age analyzing sociodemographic variables, type of CHD and short-circuit, presence of associated anomalies, and referral to a third level hospital for surgical treatment were included. Data were collected and analyzed using the SPSS Statistics v25 program. Results: The hospital prevalence of CHD that required referral to the third level hospital for surgical treatment was 6.8% in 2016 and 6.6% in 2017; the median age was 1 year. The 77.2% of CHDs were non-cyanotic, patent ductus arteriosus (PDA) was the most common shunt, and 19.2% had Down syndrome as an associated congenital anomaly. Conclusion: We obtained a similar prevalence to other regions of Mexico, with acyanotic CHD being the most frequent cause of surgical treatments. Timely detection and referral will improve care and quality of life in these patients.

De la bioética de protección a la medicina basada en la evidencia desde una perspectiva transdisciplinar

En el contexto de la bioética se debate con frecuencia el hecho de que, con el desarrollo de la ciencia y la técnica, de las tecnologías de la información y las comunicaciones, y los cambios relacionados con el ecosistema, se hace necesario garantizar el respeto de la vulnerabilidad humana y la integridad personal al aplicar y fomentar el conocimiento científico, la práctica médica y las tecnologías vinculadas (artículo 8 de la Declaración Universal sobre Bioética y Derechos Humanos). Esta vulnerabilidad se protege a través del respeto con equidad y justicia, de los derechos básicos de cada ser humano y al garantizar la integridad personal; esta es la esencia de la bioética de protección y constituye, también, la base principal de la medicina basada en la evidencia, caracterizada por el uso consciente, explícito y juicioso de la evidencia clínica en la práctica diaria para el cuidado del paciente, en aras de ofrecer la mejor atención. Existe una necesidad inmediata de proporcionar beneficios sostenibles a las personas vulnerables en situaciones de enfermedad, por ello es vital mantener un enfoque en la salud pública cubana desde la perspectiva de la bioética de protección y la transdisciplinariedad, sustentada en una medicina basada en la evidencia, en las 3 esferas, en el proceso asistencial, en el proceso pedagógico y en el investigativo; como máximo exponente de la salud global, que tiene como esencia una visión transdisciplinaria, ya que aborda la salud desde la perspectiva del derecho universal a esta y al bienestar social.

In the context of bioethics, the fact that with the development of science and technology, of information and communication technologies, and the changes related to the ecosystem, it is necessary to guarantee respect for vulnerability and personal integrity when applying and promoting scientific knowledge, medical practice and related technologies (article 8 of the Universal Declaration on Bioethics and Human Rights). This vulnerability is protected through respect, with equity and justice, for the basic rights of every human being and by guaranteeing personal integrity; this is the essence of protection bioethics and also constitutes the main basis of evidence-based medicine, characterized by the conscious, explicit and judicious use of clinical evidence in daily practice for patient care, for the sake of to offer the best care. There is an immediate need to provide sustainable benefits to vulnerable people in disease situations, for this reason it is vital to maintain a focus on Cuban public health from the perspective of protective bioethics and transdisciplinarity, supported by evident-based medicine, in the 3 spheres, in the care process, in the pedagogical process and in the investigative process; as the greatest exponent of Global Health, whose essence is a transdisciplinary vision, since it addresses health from the perspective of the universal right to it and to social well-being.

HPV Vaccine Misperceptions Among Hispanics/Latinos in Southern California.

BACKGROUND: Cervical and other vaccine-preventable HPV-associated cancers disproportionately impact Hispanic/Latinos in the USA. HPV vaccine uptake may be impacted by community agreement with common HPV vaccine misperceptions. It is unknown whether Hispanics/Latinos have a greater agreement with these misperceptions relative to non-Hispanic whites. METHODS: HPV vaccine misperceptions were assessed through a 12-item Likert scale included in a population health assessment mailed to households in the southwest United States. Linear regression models assessed the association between identifying as Hispanic/Latino and summed misperception score. RESULTS: Among the 407 individuals in the analytic sample, 111 (27.3%) were Hispanic/Latino and 296 (72.7%) were non-Hispanic white. On average, Hispanics/Latinos had a 3.03-point higher HPV vaccine misperception sum score relative to non-Hispanic whites, indicating greater agreement with misperceptions (95% confidence interval: 1.16-4.88; p < 0.01). DISCUSSION: Culturally relevant interventions are needed to address HPV vaccine misperceptions among Hispanics/Latinos as part of efforts toward HPV-associated cancer health equity.

Influence of the Sanitary, Economic, and Social Crisis of COVID-19 on the Emotional State of Dentistry in Galicia (Spain).

The main objective of this research was to analyze the economic, social, and emotional repercussions among Galician dentists (Spain) as a consequence of the COVID-19 pandemic. A survey was filled out by 347 professionals. After verifying the survey's reliability using Cronbach's alpha = 0.84, the professional activity and emotional state of the participants were assessed based on aspects related to their personal and family data. The economic impact of the pandemic was considerable, and all participants experienced a decrease in income. In total, 72% of the participants considered that working with personal protective equipment (PPE) made their clinical activities difficult, and 60% expressed concern about being infected during their professional practice. Among the professionals, women (p = 0.005), and separated, divorced, or single professionals (p = 0.003) were the most strongly affected. Separated or divorced professionals were the group that most frequently raised the need to make a radical change in their lives. Finally, it was observed that the emotional consequences varied substantially in the lives of these professionals, mainly among female dentists (p = 0.010), separated and divorced men (p = 0.000), and those with fewer years of professional practice (p = 0.021). The COVID-19 pandemic had an economic impact, due to the decrease in the number of patients and hours of attention, as well as an emotional impact, mostly expressed in the form of sleep disorders and stress. The most vulnerable professionals were women and professionals with fewer years of experience.

Assessment of potential contamination and acid drainage generation in uranium mining zones of Peña Blanca, Chihuahua, Mexico.

Potential pollution of mining environmental liabilities' locations can be preliminarily and efficiently assessed by the potential generation of acid mine drainage and indices of contamination. This research evaluates the potential pollution by potentially toxic elements at locations with uranium mining liability evidence, using the net acid generation test and determining the background values to estimate acid mine drainage and indices of contamination. Sixty soil samples were collected, and the mineralogy and potentially toxic elements' total contents were determined by x-ray diffraction and optical spectrometry. The findings suggest that the soils related to a specific lithology might not present potential acid mine drainage generation but potential soil and sediment contamination. Future research is recommended on applying leaching tests to identify which potentially toxic elements are effectively being solubilized. Finally, it can be concluded that the study area's potential contamination is relatively low overall.

COVID-19 and Public Health Spending; Effects on the Economic Sustainability of the Spanish Private Healthcare System.

This research analyzes the influence of COVID-19 and public health spending policies on the economic sustainability of Spanish private hospitals. Moreover, it explores the relationship between public health spending policies and the spread of COVID-19 in Spain. Private health care is an understudied sector, yet it is fundamental to the health of citizens. Moreover, the economic causes linked to the spread of the pandemic have not yet been clearly established. Therefore, this work covers a gap in the literature. Private hospital profitability was analyzed by applying ordinary least squares and panel data regressions on financial and macroeconomic data for the period 2017-2020. The spread of COVID-19 was examined by means of cluster and component analysis. The results show that the COVID-19 pandemic negatively affected the economic sustainability of Spanish private hospitals, which was also influenced by public health spending. In turn, the spread of the pandemic was mainly related to population density, but was also influenced by public health spending and the gross domestic product of the region. Therefore, policymakers must consider that it is essential to make adequate investments in the healthcare system to cope with pandemics such as COVID-19. In addition, managers can see how corporate social responsibility is a valuable strategy for maintaining hospital profitability.

Lack of association between endocrine disrupting chemicals and male fertility: A systematic review and meta-analysis.

The incidence of infertility currently affects about 15% of the world's population. Male factors are estimated to be responsible for up to 40-50% of these cases. While the cause of these reproductive disorders is still unclear, the exposure to a family of ubiquitous compounds in our daily life, named endocrine disrupting chemicals (EDCs) could be involved. This paper was aimed at performing a systematic review and meta-analysis of population studies exploring whether human male exposure to EDCs affects male fertility. Clinical and observational studies assessing the exposure to EDCs along with sperm quality, the most common reproductive disorders, sperm DNA damage, sperm oxidative stress, fertilization rate, implantation rate, clinical pregnancy rate, live birth rate, and miscarriage rate were included. The quality assessment tool from the NHLBI-NIH was used to assure that studies met standardized quality criteria. Sensitivity analysis and heterogeneity among studies was assessed. Overall, the 32 selected articles, including 7825 individuals in the systematic review, explored 12 families of EDCs. The results revealed a high heterogeneity among studies in relation to the association between exposure to EDCs and the endpoints analyzed. Meta-analyses were performed with data from 7 articles including 479 individuals, 4 articles assessing the association between BPA in urine and sperm quality, and 3 articles evaluating PCB153 in serum and sperm quality. In the meta-analysis, we identified an unpredicted significant positive association between PCB153 exposure and sperm concentration. However, it would not be clinically relevant. No positive or inverse associations were found neither for BPA, nor for PCB153 and the rest of sperm parameters analyzed. The high disparity between studies made difficult to draw conclusions on the potential harmful effects of EDCs on male fertility. Consequently, to delineate the potential relationship that EDCs can have on male fertility, an important condition stressing the health system, further investigations are required.

Gender and social protection and health policies promoted during the COVID-19 pandemic: Global scoping review and future challenges.

Background: Governmental interventions have been important tools for mitigating COVID-19 transmission, but they have also negatively impacted different gender-related components. We aimed to answer the following questions: What is the scope of the gender approach in the literature analysing health and social protection policies promoted during the COVID-19 pandemic? What are the challenges and recommendations for gender-sensitive policies for the post-pandemic and future crises? Methods: The study design is based on three stages: a global synthesis of the evidence through a scoping review, the generation of a framework of emerging inequalities based on sociocultural markers, and the creation of a matrix with the challenges and recommendations. In this scoping review, we searched 10 online databases for studies published until April 2022 and conducted a content analysis on the extracted studies. Results: Of the 771 identified records, 67 met our inclusion criteria. Most studies had a female person (52/67) as the first author. The binary model was the main approach addressed in the studies (61/67). The literature showed that the closure, distancing, and other social policies did not include a gender approach and generated negative gaps related to economic instability, reproductive roles, and gender violence. In the intersectionality dimension, multiple aspects emerged (macro, meso, micro-social level, and individual level). Greater gender gaps in connection with employment (related to increased housework) were observed during the closure and distancing stage of the pandemic. Asymmetries related to female participation in the management of the pandemic and an increase in discrimination and abuse of diversity groups were detected. Conclusions: We observed gaps both in the gender approach both in knowledge and in policy implementation during the pandemic in the different countries explored in this work. This is a call to attention and action for researchers, political decision-makers, and other interested parties to incorporate and accentuate the gender perspective in all policies related to the post-pandemic period and future social and health crises.

Is it Feasible to Use a Low-Cost Wearable Sensor for Heart Rate Monitoring within an Upper Limb Training in Spinal Cord Injured Patients?: A Pilot Study.

(1) Background: Cervical spinal cord injury (SCI) patients have impairment in the autonomic nervous system, reflected in the cardiovascular adaption level during the performance of upper limb (UL) activities carried out in the rehabilitation process. This adaption level could be measured from the heart rate (HR) by means of wearable technologies. Therefore, the objective was to analyze the feasibility of using Xiaomi Mi Band 5 wristband (XMB5) for HR monitoring in these patients during the performance of UL activities; (2) Methods: The HR measurements obtained from XMB5 were compared to those obtained by the professional medical equipment Nonin LifeSense II capnograph and pulse oximeter (NLII) in static and dynamic conditions. Then, four healthy people and four cervical SCI patients performed a UL training based on six experimental sessions; (3) Results: the correlation between the HR measurements from XMB5 and NLII devices was strong and positive in healthy people (r = 0.921 and r = 0.941 (p < 0.01) in the static and dynamic conditions, respectively). Then, XMB5 was used within the experimental sessions, and the HR oscillation range measured was significantly higher in healthy individuals than in patients; (4) Conclusions: The XMB5 seems to be feasible for measuring the HR in this biomedical application in SCI patients.

Residential Environment Assessment by Older Adults in Nursing Homes during COVID-19 Outbreak.

The most vulnerable residential settings during the COVID-19 pandemic were older adult's nursing homes, which experienced high rates of incidence and death from this cause. This paper aims to ascertain how institutionalized older people assessed their residential environment during the pandemic and to examine the differences according to personal and contextual characteristics. The COVID-19 Nursing Homes Survey (Madrid region, Spain) was used. The residential environment assessment scale (EVAER) and personal and contextual characteristics were selected. Descriptive and multivariate statistical analysis were applied. The sample consisted of 447 people (mean age = 83.8, 63.1% = women, 50.8% = widowed, 40% = less than primary studies). Four residential assessment subscales (relationships, mobility, residential aspects, privacy space) and three clusters according to residential rating (medium-high with everything = 71.5% of cases, low with mobility = 15.4%, low with everything = 13.1%) were obtained. The logistic regression models for each cluster category showed to be statistically significant. Showing a positive affect (OR = 1.08), fear of COVID-19 (OR = 1.06), high quality of life (OR = 1.05), not having suspicion of depression (OR = 0.75) and performing volunteer activities (OR = 3.67) were associated with the largest cluster. It is concluded that a better residential evaluation was related to more favourable personal and contextual conditions. These results can help in the design of nursing homes for older adults in need of accommodation and care to facilitate an age-friendly environment.
