RESUMO

BACKGROUND: We have conducted cooperative campaigns focusing on albino patients in a rural area of Malawi. What have we learned? METHODS: Three surgical campaigns were performed in Nkhotakota district (2019-2023). Albino clinical and tumor characteristics were collected. RESULTS: Between 22 and 75 albinos were evaluated in each campaign (mean age < 28 years old). Most patients did not use sunscreen in a way that provided optimal photoprotection. Regarding tumors, the proportion of basal and squamous cell carcinomas ranged from 1:1 to almost 2:1. Of 156 albino patients, 34 attended more than once. However, of the 19 patients with 30 tumors operated on in 2021, only seven were assessed the following year (12 were lost to follow-up). At least 14 albinos with locally advanced tumors were evaluated. CONCLUSIONS: Distributing photoprotective clothing could be more efficient or perhaps an earlier measure of sunscreen in rural Africa as it does not require permanent repositioning. Very-high-risk patients (previous interventions with positive margins or high-risk tumors, intense actinic damage, and new tumors constantly appearing, especially those presenting SCCs) require close follow-up and treatment and represent our main target. Secondary prevention with Malawian collaboration and the use of teledermatology is essential for patient tracking, as they are able to offer curative treatments.

RESUMO

Inefficient glucose metabolism and decreased ATP production in the brain are linked to ageing, cognitive decline, and neurodegenerative diseases (NDDs). This study employed thermodynamic analysis to assess the effect of fish oil supplementation on glucose metabolism in ageing brains. Data from previous studies on glucose metabolism in the aged human brain and grey mouse lemur brains were examined. The results demonstrated that Omega-3 fish oil supplementation in grey mouse lemurs increased entropy generation and decreased Gibbs free energy across all brain regions. Specifically, there was a 47.4% increase in entropy generation and a 47.4 decrease in Gibbs free energy in the whole brain, indicating improved metabolic efficiency. In the human model, looking at the specific brain regions, supplementation with Omega-3 polyunsaturated fatty acids (n-3 PUFAs) reduced the entropy generation difference between elderly and young individuals in the cerebellum and particular parts of the brain cortex, namely the anterior cingulate and occipital lobe, with 100%, 14.29%, and 20% reductions, respectively. The Gibbs free energy difference was reduced only in the anterior cingulate by 60.64%. This research underscores that the application of thermodynamics is a comparable and powerful tool in comprehending the dynamics and metabolic intricacies within the brain.

RESUMO

High daily intake of saturated fats and refined carbohydrates, which often leads to obesity and overweight, has been associated with cognitive impairment, premature brain aging and the aggravation of neurodegenerative diseases. Although the molecular pathology of obesity-related brain damage is not fully understood, the increased levels of oxidative stress induced by the diet seem to be definitively involved. Being protein carbonylation determinant for protein activity and function and a main consequence of oxidative stress, this study aims to investigate the effect of the long-term high-fat and sucrose diet intake on carbonylated proteome of the cerebral cortex of Sprague-Dawley rats. To achieve this goal, the study identified and quantified the carbonylated proteins and lipid peroxidation products in the cortex, and correlated them with biometrical, biochemical and other redox status parameters. Results demonstrated that the obesogenic diet selectively increased oxidative damage of specific proteins that participate in fundamental pathways for brain function, i.e. energy production, glucose metabolism and neurotransmission. This study also evaluated the antioxidant properties of fish oil to counteract diet-induced brain oxidative damage. Fish oil supplementation demonstrated a stronger capacity to modulate carbonylated proteome in the brain cortex. Data indicated that fish oils did not just decrease carbonylation of proteins affected by the obesogenic diet, but also decreased the oxidative damage of other proteins participating in the same metabolic functions, reinforcing the beneficial effect of the supplement on those pathways. The results could help contribute to the development of successful nutritional-based interventions to prevent cognitive decline and promote brain health.

RESUMO

Biocomposites create attractive alternatives to match packing needs with available agricultural residues. Growing native fungal strains developed a mycelium biocomposite over a mixture of Peach Palm Fruit Peel Flour and Sugar Cane Bagasse Wet Dust. A methodology was proposed to analyze their main characteristics: 1) morphological, 2) chemical, and 3) biodegradability. 1) SEM analysis evidenced the structural change of the dried vs pressed material and mycelium morphology for both species. 2) The ratio lignin:carbohydrate showed that P. ostreatus degrades the cellulose-hemicellulose fraction of the substrate at a higher rate than T. elegans, and 3) the curve BMP indicated that these materials are readily biodegradable with a maximum yield of 362,50 mL biogas/g VS. An innovative tangible valorization strategy based on mass balances is also presented: from just 50 kg of peel flour, up to 1840 units can be manufactured, which could pave the way for a more sustainable future.

RESUMO

Obesity has been recognized as a major risk factor for chronic kidney disease, insulin resistance being an early common metabolic feature in patients suffering from this syndrome. This study aims to investigate the mechanism underlying the induction of kidney dysfunction and the concomitant onset of insulin resistance by long-term high-fat and sucrose diet feeding in Sprague Dawley rats. To achieve this goal, our study analyzed renal carbonylated protein patterns, ectopic lipid accumulation and fatty acid profiles and correlated them with biometrical and biochemical measurements and other body redox status parameters. Rats fed the obesogenic diet developed a prediabetic state and incipient kidney dysfunction manifested in increased plasma urea concentration and superior levels of renal fat deposition and protein carbonylation. An obesogenic diet increased renal fat by preferentially promoting the accumulation of saturated fat, arachidonic, and docosahexaenoic fatty acids while decreasing oleic acid. Renal lipotoxicity was accompanied by selectively higher carbonylation of proteins involved in the blood pH regulation, i.e., bicarbonate reclamation and synthesis, amino acid, and glucose metabolisms, directly related to the onset of insulin resistance. This study also tested the combination of antioxidant properties of fish oil with the anti-diabetic properties of buckwheat D-Fagomine to counteract diet-induced renal alterations. Results demonstrated that bioactive compounds combined attenuated lipotoxicity, induced more favorable lipid profiles and counteracted the excessive carbonylation of proteins associated with pH regulation in the kidneys, resulting in an inhibition of the progression of the prediabetes state and kidney disease.

RESUMO

Aim: To determine nursing outcomes in individuals with intestinal stoma and the relationships between them and sociodemographic and clinical variables. Design: Cross-sectional study performed with 102 subjects at the General Surgery Unit of a first-level hospital. Methods: Data on the presence of nursing outcomes were collected using the Nursing Outcomes Classification. Data on sociodemographic and clinical variables were also collected. Univariate and bivariate data analyses were performed. Results: Outcomes related to participation in making health decisions and knowledge of ostomy care were assessed across the study sample. Period of care (post-operative and follow-up) was the most common significant variable (p < 0.05) among the outcomes. The outcome scores ranged from 2 to 3, indicating a moderate level of impairment in the physical, psychological, and social spheres of these patients. The scores in the indicators on Participation in making health decisions and Knowledge of stoma care improved in the period of continuity of care compared to the postoperative period, being this difference statistically significant (p < 0.001). Conclusions: The care plan for individuals with intestinal stoma needs to include indicators measuring patient participation in making decisions related to their condition, as well as indicators related to their knowledge and self-care of their stoma. Relevance to clinical practice: This study aims to determine the nursing outcomes in individuals with intestinal stoma and the relationships between them and sociodemographic and clinical variables. It provides the opportunity to plan achievable objectives with patients using a system of indicators that facilitate their assessment and monitoring.

RESUMO

Green extraction was applied to Argentinean shortfin squid (Illex argentinus) viscera, consisting of a wet pressing method including a drying step, mechanic pressing, centrifugation of the resulting slurry, and oil collection. To maximise the oil yield and ω3 fatty acid content and to minimise the oil damage degree, a response surface methodology (RSM) design was developed focused on the drying temperature (45-85 °C) and time (30-90 min). In general, an increase of the drying time and temperature provided an increase in the lipid yield recovery from the viscera. The strongest drying conditions showed a higher recovery than 50% when compared with the traditional chemical method. The docosahexaenoic and eicosapentaenoic acid contents in the extracted oil revealed scarce dependence on drying conditions, showing valuable ranges (149.2-166.5 and 88.7-102.4 g·kg-1 oil, respectively). Furthermore, the values of free fatty acids, peroxides, conjugated dienes, and ω3/ω6 ratio did not show extensive differences by comparing oils obtained from the different drying conditions. Contrary, a polyene index (PI) decrease was detected with increasing drying time and temperature. The RSM analysis indicated that optimised drying time (41.3 min) and temperature (85 °C) conditions would lead to 74.73 g·kg-1 (oil yield), 1.87 (PI), and 6.72 (peroxide value) scores, with a 0.67 desirability value.

RESUMO

Omega-3 polyunsaturated fatty acids are associated with a lower risk of cardiometabolic diseases. However, docosahexaenoic acid (DHA) is easily oxidized, leading to cellular damage. The present study examined the effects of an increased concentration of DHA in fish oil (80% of total fatty acids) on cardiometabolic risk factors and oxidative stress compared to coconut oil, soybean oil, and fish oil containing eicosapentaenoic acid (EPA) and DHA in a balanced ratio. Forty healthy male Sprague-Dawley rats were supplemented with corresponding oil for 10 weeks. Supplementation with the fish oil containing 80% DHA decreased plasma fat, plasma total cholesterol and muscle fat compared to the coconut oil and the soybean oil. Increasing concentrations of DHA induced incorporation of DHA and EPA in cell membranes and tissues along with a decrease in ω-6 arachidonic acid. The increase in DHA promoted lipid peroxidation, protein carbonylation and antioxidant response. Taken together, the increased concentration of DHA in fish oil reduced fat accumulation compared to the coconut oil and the soybean oil. This benefit was accompanied by high lipid peroxidation and subsequent protein carbonylation in plasma and in liver. In our healthy framework, the slightly higher carbonylation found after receiving fish oil containing 80% DHA might be a protecting mechanism, which fit with the general improvement of antioxidant defense observed in those rats.

RESUMO

Noncommunicable diseases (NCD) and age-associated diseases (AAD) are some of the gravest health concerns worldwide, accounting for up to 70% of total deaths globally. NCD and AAD, such as diabetes, obesity, cardiovascular disease, and cancer, are associated with low-grade chronic inflammation and poor dietary habits. Modulation of the inflammatory status through dietary components is a very appellative approach to fight these diseases and is supported by increasing evidence of natural and dietary components with strong anti-inflammatory activities. The consumption of bioactive lipids has a positive impact on preventing chronic inflammation and consequently NCD and AAD. Thus, new sources of bioactive lipids have been sought out. Microalgae are rich sources of bioactive lipids such as omega-6 and -3 polyunsaturated fatty acids (PUFA) and polar lipids with associated anti-inflammatory activity. PUFAs are enzymatically and non-enzymatically catalyzed to oxylipins and have a significant role in anti and pro-resolving inflammatory responses. Therefore, a large and rapidly growing body of research has been conducted in vivo and in vitro, investigating the potential anti-inflammatory activities of microalgae lipids. This review sought to summarize and critically analyze recent evidence of the anti-inflammatory potential of microalgae lipids and their possible use to prevent or mitigate chronic inflammation.

RESUMO

BACKGROUND: The mini-suffering state examination is a valid and reliable measure that have been used to assess suffering in patients with advanced cancer. The aim of this study was to carry out a psychometric analysis of the Spanish version of the mini-suffering state examination. METHOD: A validation study was conducted. Seventy-two informal caregivers of deceased patients in palliative care were included in this study. A psychometric testing of content validity, internal consistency, and convergent validity with the Spanish version of the quality of dying and death questionnaire was performed. RESULTS: The original instrument was modified to be used by informal caregivers. The content validity was acceptable (0.96), and the internal consistency was moderate (α = 0.67). Convergent validity was demonstrated (r = -0.64). CONCLUSION: The Spanish modified version of the MSSE showed satisfactory measurement properties. The Spanish modified version of MSSE can be useful to facilitate screening, monitor progress, and guide treatment decisions in end-of-life cancer patients.

RESUMO

Cells in many tissues, such as bone, muscle, and placenta, fuse into syncytia to acquire new functions and transcriptional programs. While it is known that fused cells are specialized, it is unclear whether cell-fusion itself contributes to programmatic-changes that generate the new cellular state. Here, we address this by employing a fusogen-mediated, cell-fusion system to create syncytia from undifferentiated cells. RNA-Seq analysis reveals VSV-G-induced cell fusion precedes transcriptional changes. To gain mechanistic insights, we measure the plasma membrane surface area after cell-fusion and observe it diminishes through increases in endocytosis. Consequently, glucose transporters internalize, and cytoplasmic glucose and ATP transiently decrease. This reduced energetic state activates AMPK, which inhibits YAP1, causing transcriptional-reprogramming and cell-cycle arrest. Impairing either endocytosis or AMPK activity prevents YAP1 inhibition and cell-cycle arrest after fusion. Together, these data demonstrate plasma membrane diminishment upon cell-fusion causes transient nutrient stress that may promote transcriptional-reprogramming independent from extrinsic cues.

RESUMO

Adipose tissue is now recognized as an active organ with an important homeostatic function in glucose and lipid metabolism and the development of insulin resistance. The present research investigates the role of lipid mediators and lipid profiling for controlling inflammation and the metabolic normal function of white adipose tissue from rats suffering from diet-induced prediabetes. Additionally, the contribution to the adipose lipidome induced by the consumption of marine ω-3 PUFAs as potential regulators of inflammation is addressed. For that, the effects on the inflammatory response triggered by high-fat high-sucrose (HFHS) diets were studied in male Sprague-Dawley rats. Using SPE-LC-MS/MS-based metabolo-lipidomics, a range of eicosanoids, docosanoids and specialized pro-resolving mediators (SPMs) were measured in white adipose tissue. The inflammatory response occurring in prediabetic adipose tissue was associated with the decomposition of ARA epoxides to ARA-dihydroxides, the reduction of oxo-derivatives and the formation of prostaglandins (PGs). In an attempt to control the inflammatory response initiated, LOX and non-enzymatic oxidation shifted toward the production of the less pro-inflammatory EPA and DHA metabolites rather than the high pro-inflammatory ARA hydroxides. Additionally, the change in LOX activity induced the production of intermediate hydroxides precursors of SPMs as protectins (PDs), resolvins (Rvs) and maresins (MaRs). This compensatory mechanism to achieve the restoration of tissue homeostasis was significantly strengthened through supplementation with fish oils. Increasing proportions of ω-3 PUFAs in adipose tissue significantly stimulated the formation of DHA-epoxides by cytochrome P450, the production of non-enzymatic EPA-metabolites and prompted the activity of 12LOX. Finally, protectin PDX was significantly reduced in the adipose tissue of prediabetic rats and highly enhanced through ω-3 PUFAs supplementation. Taken together, these actively coordinated modifications constitute key mechanisms to restore adipose tissue homeostasis with an important role of lipid mediators. This compensatory mechanism is reinforced through the supplementation of the diet with fish oils with high and balanced contents of EPA and DHA. The study highlights new insides on the targets for effective treatment of incipient diet-induced diabetes and the mechanism underlying the potential anti-inflammatory action of marine lipids.

RESUMO

Polyphenols and omega-3 polyunsaturated fatty acids from fish oils, i.e., eicosapentaenoic and docosahexaenoic acids, are well-recognized nutraceuticals, and their single antioxidant and anti-inflammatory properties have been demonstrated in several studies found in the literature. It has been reported that the combination of these nutraceuticals can lead to three-fold increases in glutathione peroxidase activity, two-fold increases in plasma antioxidant capacity, decreases of 50-100% in lipid peroxidation, protein carbonylation, and urinary 8-isoprotanes, as well as 50-200% attenuation of common inflammation biomarkers, among other effects, as compared to their individual capacities. Therefore, the adequate combination of those bioactive food compounds and their single properties should offer a powerful tool for the design of successfully nutritional interventions for the prevention and palliation of a plethora of human metabolic diseases, frequently diet-induced, whose etiology and progression are characterized by redox homeostasis disturbances and a low-grade of chronic inflammation. However, the certain mechanisms behind their biological activities, in vivo interaction (both between them and other food compounds), and their optimal doses and consumption are not well-known yet. Therefore, we review here the recent evidence accumulated during the last decade about the cooperative action between polyphenols and fish oils against diet-related metabolic alterations, focusing on the mechanisms and pathways described and the effects reported. The final objective is to provide useful information for strategies for personalized nutrition based on these nutraceuticals.

RESUMO

OBJECTIVES: This study aimed to describe and compare symptoms, care needs and types of diagnoses in hospitalised patients with palliative care needs in Spain and Sweden. METHODS: A cross-sectional, population-based study was carried out at two hospitals in both Spain and Sweden. Using a questionnaire, we performed 154 one-day inventories (n=4213) in Spain and 139 in Sweden (n=3356) to register symptoms, care needs and diagnoses. Descriptive analyses were used. RESULTS: The proportion of patients with care needs in the two countries differed (Spain 7.7% vs Sweden 12.4%, p<0.001); however, the percentage of patients with cancer and non-cancer patients was similar. The most prevalent symptoms in cancer and non-cancer patients in both countries were deterioration, pain, fatigue and infection. The most common cancer diagnosis in both countries was lung cancer, although it was more common in Spain (p<0.01), whereas prostate cancer was more common among Swedish men (p<0.001). Congestive heart failure (p<0.001) was a predominant non-cancer diagnosis in Sweden, whereas in Spain, the most frequent diagnosis was dementia (p<0.001). Chronic obstructive pulmonary disease was common in both countries, although its frequency was higher in Spain (p<0.05). In total, patients with cancer had higher frequencies of pain (p<0.001) and nausea (p<0.001), whereas non-cancer patients had higher frequencies of deterioration (p<0.001) and infections (p<0.01). CONCLUSIONS: The similarities in symptoms among the patients indicate that the main focus in care should be on patient care needs rather than diagnoses. Integrating palliative care in hospitals and increasing healthcare professional competency can result in providing optimal palliative care.

RESUMO

Diacylglycerols (DAG) and ceramides have been suggested as early predictors of insulin resistance. This study was aimed to examine the combined effects of fish oil (FO) and grape seed extract (GSE) on hepatic endogenous antioxidants, DAG and ceramides in diet-induced early stages of insulin resistance. Thirty-five rats were fed one of the following diets: (1) a standard diet (STD group), (2) a high-fat high-sucrose diet (HFHS group), (3) an HFHS diet enriched with FO (FO group), (4) an HFHS diet enriched with GSE (GSE group) or (5) an HFHS diet enriched with FO and GSE (FO + GSE group). In the liver, endogenous antioxidants were measured using spectrophotometric and fluorometric techniques, and non-targeted lipidomics was conducted for the assessment of DAG and ceramides. After 24 weeks, the FO + GSE group showed increased glutathione peroxidase activity, as well as monounsaturated fatty acid and polyunsaturated fatty acid-containing DAG, and long-chain fatty acid-containing ceramides abundances compared to the STD group. The FO and GSE combination induced similar activation of the antioxidant system and bioactive lipid accumulation in the liver than the HFHS diet without supplementation. In addition, the FO and GSE combination increased the abundances of polyunsaturated fatty acid-containing DAG in the liver.

RESUMO

Pain, anxiety, or depression are very prevalent in children and adolescents with cancer, which is a great challenge for health professionals. Several studies pointing out the positive effect of technology on the management of symptoms have been published in recent years. Considering these studies is important in order to reduce the negative impact on the quality of life of this population. This study aimed to analyze the available evidence and to describe the benefits of the new technologies in the treatment of pain, anxiety, and depression in children and adolescents with cancer. A systematic search using six electronic databases was conducted to identify studies using technological interventions with a focus on pain, anxiety, and depression that were published from 2008 to 2018 including oncology patients from 0-18 years old. Out of the 1261 studies that were identified, five studies met the inclusion criteria for this systematic review. Robots were used in two studies, providing amusement and social interventions that showed significant improvements. Virtual reality, a mobile application, and a videogame were used in three studies and obtained beneficial results in pain and anxiety. The studies included in this review suggest that new technologies can be used as an innovative form of non-pharmacological intervention with therapeutic benefits.

RESUMO

OBJECTIVE: The objective of this study was to explore the umbilical cord separation time, predictors, and healing complications from birth until the newborn was one month old. DESIGN: A quantitative longitudinal observational analytical study by stratified random sample was adopted. SETTING: Public health system hospitals in southern Spain and at newborns' homes. PARTICIPANTS: Between April 2016 and December 2017, the study included 106 neonates born after 35-42 weeks of gestation whose umbilical cord was cured with water and soap and dried later as well as newborns without umbilical canalisation whose mothers enjoyed a low-risk pregnancy. METHODS: The data collection procedure comprised two blocks: from birth to the time of separation of the umbilical cord and from cord separation to the first month of life of the newborn. Umbilical cord separation time was measured in minutes; socio-demographic and clinical characteristics were measured by means of questionnaires, and the external diameter of the umbilical cord was measured using an electronic stainless-steel calliper and trailing roller. RESULTS: The mean umbilical separation time: 6.61 days (±2.33, IC 95%:6.16-7.05). Incidence of omphalitis was 3.7%; granuloma was 8.6%. Separation time predictors were wetting recurrence, birth weight, intrapartum antibiotics, birth season, and Apgar < 9 (R2 = 0.439 F: 15.361, p <0.01). CONCLUSION: The findings support the World Health Organization recommendations: dry umbilical cord cares is a safe practice that soon detaches the umbilical cord, taking into account the factors studied that will vary the length of time until the umbilical cord is separated.

RESUMO

Resumo Objetivo O objetivo deste estudo foi explorar as experiências e expectativas de pacientes submetidos a prostatectomia radical não poupadora de nervos. Métodos Estudo qualitativo, descritivo-exploratório, baseado na fenomenologia hermenêutica. Foram realizadas dezesseis entrevistas em profundidade entre fevereiro e dezembro de 2017 e análise indutiva dos dados. Resultados Dois temas que refletem as experiências dos pacientes emergiram da análise: (1) As mudanças sexuais como fator-chave da resposta adaptativa, com os subtemas "Dificuldades sexuais após a cirurgia" e "Questões com relacionamentos íntimos e bem-estar psicossocial"; (2) Prostatectomia: a necessidade de adaptação a uma sexualidade holística, com os subtemas "Questionamento das experiências a partir do comportamento sexual atual" e "Adaptação da sexualidade e a intimidade após a cirurgia". Conclusão Pacientes submetidos à prostatectomia enfrentam dificuldades sexuais como disfunção erétil. Essas mudanças causam problemas nos relacionamentos sexuais e íntimos que afetam seu bem-estar. Diante dessa situação, alguns participantes questionam suas práticas sexuais habituais e tentam se adaptar a uma sexualidade holística não centrada no coito, incorporando formas inovadoras de sexualidade. Conhecer as experiências de homens submetidos a prostatectomia radical pode ajudar os profissionais de saúde a oferecer novas estratégias para lidar com as mudanças ambientais envolvidas na cirurgia da próstata.

Resultados A partir del análisis, surgieron dos temas que reflejan las experiencias de los pacientes: (1) Los cambios sexuales como factor clave de la respuesta adaptativa, con dos subtemas "Dificultades sexuales después de la cirugía" y "Cuestiones sobre relaciones íntimas y bienestar psicosocial" y (2) Prostatectomía: necesidad de adaptación a una sexualidad holística, con los subtemas "Cuestionamiento de las experiencias a partir del comportamiento sexual actual" y "Adaptación de la sexualidad e intimidad después de la cirugía". Conclusión Los pacientes sometidos a prostatectomía enfrentan dificultades sexuales como disfunción eréctil. Estos cambios causan problemas en las relaciones sexuales e íntimas que afectan su bienestar. Ante esta situación, algunos participantes cuestionan sus prácticas sexuales habituales e intentan adaptarse a una sexualidad holística no centrada en el coito, incorporando formas innovadoras de sexualidad. Conocer las experiencias de hombres sometidos a prostatectomía radical puede ayudar a los profesionales de la salud a ofrecer nuevas estrategias para lidiar con los cambios ambientales relacionados con la cirugía de próstata.


Abstract Objective The aim of this study was to explore the experiences and expectations of patients who underwent non-nerve sparing radical prostatectomy. Methods A qualitative descriptive, exploratory, study, based on hermeneutic phenomenology. Sixteen in-depth interviews were carried out between February and December 2017. An inductive analysis of data was performed. Results Two themes reflecting the patients' experiences emerged from the analysis: (1) Sexual changes as a key factor of the adaptive response, with the subthemes "Sexual difficulties after surgery" and "Issues with intimate relationships and psychosocial wellbeing". (2) Prostatectomy: the need of adaptation to a holistic sexuality, with the subthemes "Questioning the experiences from the current sexual behavior" and "Adapting sexuality and intimacy after surgery". Conclusion Patients undergoing prostatectomy face sexual difficulties such as erectile dysfunction. These changes cause problems in sexual and intimate relationships that affect their wellbeing. Given this situation, some participants question their usual sexual practices and try to adapt to a holistic sexuality not centered on coitus by incorporating innovative forms of sexuality. Knowing the experiences of men who underwent radical prostatectomy might help healthcare workers to provide new strategies for coping with the environmental changes involved in prostate surgery.

RESUMO

INTRODUCTION: Although fibromyalgia symptoms negatively affect patients' sexual life, sexual desire in women diagnosed with fibromyalgia has been understudied. AIM: To describe and compare sexual desire in women diagnosed with fibromyalgia and healthy control women, and to investigate the influence of fibromyalgia and its pharmacologic treatment on sexual desire among women diagnosed with fibromyalgia. METHODS: 164 women diagnosed with fibromyalgia participated in the study. Participants' sexual desire, fibromyalgia symptoms, symptom interference in daily life activities, and perceived quality of life were measured. Further sociodemographic and health-related data were also recorded. 87 healthy women were selected as a control group, and their sexual desire was compared with those of women diagnosed with fibromyalgia. MAIN OUTCOME MEASURES: Main outcome measures included the Sexual Desire Inventory and the Fibromyalgia Impact Questionnaire. RESULTS: When compared with healthy control subjects, women diagnosed with fibromyalgia exhibited a significantly lower mean score on total desire (47.92 ± 17.48 vs 26.33 ± 21.95; P < .001), solitary desire (10.52 ± 5.96 vs 5.74 ± 7.01; P < .001), and dyadic desire (37.40 ± 13.98 vs 20.59 ± 16.94; P < .001). Women diagnosed with fibromyalgia who were taking antidepressants scored significantly lower on dyadic desire (P < .001), solitary desire (P < .001), and total desire (P < .001) than those who were not. Furthermore, a negative correlation between desire (dyadic and solitary) and Revised Fibromyalgia Impact Questionnaire (total and all subscales) was found. Linear regression showed that taking antidepressants, age, and the total Fibromyalgia Impact Questionnaire score explained 16% of the variance of total desire. CLINICAL IMPLICATIONS: Knowing how fibromyalgia symptoms and their pharmacologic treatment affect women's sexual desire may have implications for designing care strategies according to individual needs. STRENGTHS & LIMITATIONS: To the best of our knowledge, this is the first study that focuses on studying the impact of fibromyalgia on dyadic and solitary sexual desire. Limitations are related to having used an online questionnaire for data collection, having recruited the participants through a convenience sampling technique and not being able to isolate whether certain results are related to fibromyalgia symptoms or are side effects of the pharmacologic treatment used for symptom control. CONCLUSION: Fibromyalgia impact seems to negatively influence dyadic and solitary sexual desire in women. In addition, other factors such as age or taking antidepressant drugs may result in lower sexual desire in these patients. López-Rodríguez MM, Pérez Fernández A, Hernández-Padilla JM, et al.

RESUMO

INTRODUCTION: The prevention and relief of suffering are regarded as a goal at the end of life; therefore, suffering assessment at the end of life is essential. In this regard, we need instruments that allow us to evaluate this construct for gathering more evidence, as the assessment of suffering is increasingly used in research and the clinical setting. Many measures have been designed to assess this construct, and the selection of the most appropriate instrument is crucial. The aims of this systematic review are to (1) identify the measures assessing suffering in patients with advanced disease and their psychometric properties and (2) evaluate the methodological quality of studies on measurement properties. METHODS AND ANALYSIS: The protocol of this systematic review was developed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols Guidelines. A systematic psychometric review of measures assessing suffering in patients with advanced disease and their psychometric properties will be carried out according to the COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN). The search strategy will be performed following the Peer Review of Electronic Search Strategies. Searches will be conducted in Cumulative Index to Nursing and Allied Health Literature, Medline, PsycINFO, Cochrane Library, SciELO, Open Grey, Scopus, Web of Science and COSMIN database of systematic reviews, and it will be limited by time (1980-2018) and language (only literature in English and Spanish). Literature will be evaluated by two independent reviewers according to the COSMIN checklist, and measurement properties data of each study that meet the inclusion criteria will be scored independently by two researchers according to COSMIN quality ratings. ETHICS AND DISSEMINATION: Ethical approval is not necessary for systematic review protocols. The results will be disseminated by publication in a peer-reviewed journal and presented at a relevant conference. PROSPERO REGISTRATION NUMBER: CRD42018106488.
