Infantile Hemangioma in Infancy: A Case Study on the Natural Course and Therapeutic Management.

Infantile hemangiomas (IHs) are common benign vascular tumors that affect infants. In this case report, we detail the natural course of an IH in an infant monitored over four months without medical intervention, illustrating the benign progression and potential for spontaneous stabilization of such lesions. The aim was to observe changes in the size and morphology of the hemangioma, alongside the infant's overall health and developmental milestones, through regular clinical assessments. This case presented a challenge as the patient's parents lacked English fluency, lacked healthcare access, and had low socioeconomic status. It highlights the importance of individualized patient care, advocating for careful observation and restraint in the application of pharmacological treatments when clinically unnecessary. The report contributes to existing pediatric dermatology knowledge by emphasizing the natural benign behavior of IH and the need for a balanced approach to treatment decisions, ensuring safe and favorable long-term outcomes for patients.

Uncommon Etiologies of Acute Abdominal Pain: A Case Report on Omental Infarction.

Omental infarction is an uncommon cause of abdominal pain. The condition is often misdiagnosed due to its clinical similarity to more common abdominal pathologies like appendicitis and cholecystitis. This report presents the case of a 57-year-old female with a one-week history of left-sided abdominal pain, initially aggravated by eating and defecation. The patient, a long-term smoker with a complex medical history that includes deep vein thrombosis and pulmonary embolism, was hemodynamically stable on presentation. A CT scan revealed a nodular infiltration consistent with an omental infarct. Conservative management was pursued, resulting in symptom resolution by the third day of hospitalization. This case underscores the diagnostic challenges associated with omental infarction, particularly its differentiation from other causes of acute abdominal pain. It highlights the importance of considering rare etiologies in patients with atypical presentations and emphasizes the role of imaging, particularly CT scans, in accurate diagnosis. The patient's successful conservative management aligns with current recommendations, which advocate for non-surgical treatment in most cases. This approach avoids unnecessary surgical interventions and ensures a favorable prognosis with low complication rates in patients with prompt and appropriate management.

Improving Assessment and Learning Environments for Graduate Medical Trainees to Advance Healthcare Language Equity.

Language-appropriate care is critical for equitable, high-quality health care, but educational standards to assure graduate medical trainees are prepared to give such care are lacking. Detailed guidance for graduate medical education is provided by the Accreditation Council for Graduate Medical Education through the following: (1) an assessment framework for competencies, subcompetencies, and milestones for trainees and (2) the Clinical Learning Environment Review (CLER) Pathways for assessment of trainees' learning environments. These tools do not include a robust framework to evaluate trainees' abilities to offer language-appropriate care. They also do not address the learning environment's potential to support such care. A multidisciplinary group of linguistic, medical, and educational experts drafted a new subcompetency with milestones and an expanded CLER Pathway to highlight the importance of equitable care for patients who prefer languages other than English. These resources offer residency and fellowship programs tools to guide assessment, curriculum development, and learning-environment improvements related to language-appropriate care. Recognizing that programs have unique needs and resources, we propose a range of initial actions to address language equity. A focus on language diversity in the learning environment can have a broad and lasting impact on care quality, patient safety, and health equity.

Recommendations for the primary prevention of atherosclerotic cardiovascular disease in primary care: study protocol for a systematic guideline review.

INTRODUCTION: Atherosclerotic cardiovascular disease (ASCVD) was the main cause of death in Germany in 2021, with major risk factors (ie, hypertension, diabetes, dyslipidaemia, obesity and certain lifestyle factors) being highly prevalent. Preventing ASCVD by assessment and modification of these risk factors is an important challenge for general practitioners. This study aims to systematically review and synthesise recent recommendations of national and international guidelines regarding the primary prevention of ASCVD in adults in primary care. METHODS AND ANALYSIS: We will conduct a systematic review of clinical practice guidelines (CPGs) to evaluate primary prevention strategies for ASCVD. CPGs will be retrieved from MEDLINE and the Turning Research Into Practice database, guideline-specific databases and websites of guidelines-producing societies, with searches limited to publications from 2016 onwards. We will include CPGs in English, Spanish, German or Dutch languages that provide evidence-based recommendations for ASCVD prevention. The study population will include adults without diagnosed ASCVD. Two independent reviewers will assess guideline eligibility and quality by means of the mini-checklist MiChe, and extract study characteristics and relevant recommendations for further consistency analysis. A third reviewer will resolve disagreements. Findings will be presented as a narrative synthesis and in tabular form. ETHICS AND DISSEMINATION: This review does not require ethical approval. Our systematic review will inform the CPG of the German College of General Practitioners and Family Physicians on the primary prevention of ASCVD. The review results will also be disseminated through publications in peer-reviewed journals and presentations at local, national and international conferences.

Complex Surgical Intervention for Small Bowel Obstruction Secondary to Metastatic Colorectal Cancer.

Small bowel obstruction (SBO) refers to the inability of contents to pass through the lumen of the small intestine. This is a common surgical emergency in the United States. Although intra-abdominal adhesions are the predominant cause, SBO can occur secondarily to various etiologies, be it one cause or several. Management of SBO secondary to adhesions and metastasized rectal adenocarcinoma, complicated by pulmonary, hepatic, and ureteral disease, highlights the criticality of a multidisciplinary approach. We present a case of a 59-year-old male with SBO secondary to rectal adenocarcinoma. Treatment included surgical resection, acute stabilization, referral for outpatient surgical follow-up, and oncologic management.

Effectiveness of exercise interventions to improve long-term outcomes in people living with mild cognitive impairment: a systematic review and meta-analysis.

Although exercise guidelines now recommend exercise for patients with MCI, the long-term effects of exercise in patients with MCI has not been reviewed systematically. The aim was to assess (1) the effectiveness of exercise and physical activity (EXPA) interventions in improving long-term patient-relevant cognitive and non-cognitive outcomes in people with mild cognitive impairment, (2) how well the included trials reported details of the intervention, and (3) the extent to which reported endpoints were in line with patient preferences that were assessed in patient workshops. Following PRISMA guidelines, we performed a systematic review and meta-analysis including randomized controlled trials. A total of ten studies were included after searching in six electronic sources from 1995 onwards. There is a trend that 6 + -month EXPA interventions improve global cognition 12 months after initiation. Evidence on long-term effects of EXPA interventions on non-cognitive health outcomes could not be meaningfully pooled and the individual studies reported mixed results. Workshop participants considered freedom from pain and stress, mood, motivation and self-efficacy to be important, but these outcomes were rarely addressed. Too little information is available on intervention details for EXPA programs to be replicated and confidently recommended for patients with MCI.

Cancer-Related Pain Management in Suitable Intrathecal Therapy Candidates: A Spanish Multidisciplinary Expert Consensus.

A consensus is needed among healthcare professionals involved in easing oncological pain in patients who are suitable candidates for intrathecal therapy. A Delphi consultation was conducted, guided by a multidisciplinary scientific committee. The 18-item study questionnaire was designed based on a literature review together with a discussion group. The first-round questionnaire assessed experts' opinion of the current general practice, as well as their recommendation and treatment feasibility in the near future (2-3-year period) using a 9-point Likert scale. Items for which consensus was not achieved were included in a second round. Consensus was defined as ≥75% agreement (1-3 or 7-9). A total of 67 panelists (response rate: 63.2%) and 62 (92.5%) answered the first and second Delphi rounds, respectively. The participants were healthcare professionals from multiple medical disciplines who had an average of 17.6 (7.8) years of professional experience. A consensus was achieved on the recommendations (100%). The actions considered feasible to implement in the short term included effective multidisciplinary coordination, improvement in communication among the parties, and an assessment of patient satisfaction. Efforts should focus on overcoming the barriers identified, eventually leading to the provision of more comprehensive care and consideration of the patient's perspective.

How do middle-aged patients and their healthcare providers manage multimorbidity? Results of a qualitative study.

BACKGROUND: It is particularly difficult for healthcare providers to deliver optimal medical care to multimorbid middle-aged persons because patients' professional activities, family lives, and other everyday responsibilities hinder them from making necessary lifestyle changes. Our aim was to find out how patients and healthcare providers view and manage the problems of dealing with multimorbidity in middle age. METHODS AND FINDINGS: This qualitative study consisted of three steps. First, we conducted semi-structured in-depth interviews with 15 purposively sampled middle-aged persons living with multimorbidity to explore the experiences of care in the context of their leisure time, family lives, and work. Second, further individual interviews were carried out to find out the views of 14 healthcare providers. Third, the results of the interviews with patients and healthcare providers were presented to and discussed with four healthcare providers at an interprofessional workshop. Interview data was coded using an inductive-deductive approach and analyzed using content analysis. While patients reflected on challenges in several life domains, healthcare providers differentiated between levels of challenges. Both shared recommendations for better care including i) helping patients cope, ii) providing relief in activities of daily living, iii) continuity of care, iv) interprofessional cooperation, v) health promotion/prevention, vi) expansion of health services and vii) general system-level changes. Furthermore, the healthcare provider workshop highlighted the importance of increasing patient-centeredness, reducing complexity through a care coordinator and promoting interprofessional cooperation/networking. CONCLUSIONS: To further improve the care of patients living with multimorbidity, barriers to managing multiple chronic conditions and facilitators to navigating complex care scenarios should be explored not only for people beyond working age, but for individuals in their mid-life specifically.

Amitriptyline's anticholinergic adverse drug reactions-A systematic multiple-indication review and meta-analysis.

BACKGROUND: Half the US population uses drugs with anticholinergic properties. Their potential harms may outweigh their benefits. Amitriptyline is among the most frequently prescribed anticholinergic medicinal products, is used for multiple indications, and rated as strongly anticholinergic. Our objective was to explore and quantify (anticholinergic) adverse drug reactions (ADRs) in patients taking amitriptyline vs. placebo in randomized controlled trials (RCTs) involving adults and healthy individuals. METHODS: We searched electronic databases from their inception until 09/2022, and clinical trial registries from their inception until 09/2022. We also performed manual reference searches. Two independent reviewers selected RCTs with ≥100 participants of ≥18 years, that compared amitriptyline (taken orally) versus placebo for all indications. No language restrictions were applied. One reviewer extracted study data, ADRs, and assessed study quality, which two others verified. The primary outcome was frequency of anticholinergic ADRs as a binary outcome (absolute number of patients with/without anticholinergic ADRs) in amitriptyline vs. placebo groups. RESULTS: Twenty-three RCTs (mean dosage 5mg to 300mg amitriptyline/day) and 4217 patients (mean age 40.3 years) were included. The most frequently reported anticholinergic ADRs were dry mouth, drowsiness, somnolence, sedation, fatigue, constitutional, and unspecific anticholinergic ADRs. Random-effects meta-analyses showed anticholinergic ADRs had a higher odd's ratio for amitriptyline versus placebo (OR = 7.41; [95% CI, 4.54 to 12.12]). Non-anticholinergic ADRs were as frequent for amitriptyline as placebo. Meta-regression analysis showed anticholinergic ADRs were not dose-dependent. DISCUSSION: The large OR in our analysis shows that ADRs indicative of anticholinergic activities can be attributed to amitriptyline. The low average age of participants in our study may limit the generalizability of the frequency of anticholinergic ADRs in older patients. A lack of dose-dependency may reflect limited reporting of the daily dosage when the ADRs occurred. The exclusion of small studies (<100 participants) decreased heterogeneity between studies, but may also have reduced our ability to detect rare events. Future studies should focus on older people, as they are more susceptible to anticholinergic ADRs. REGISTRATION: PROSPERO: CRD42020111970.

Análisis de posibles peligros en leche materna donada. Revisión / Analysis of potential hazards in donated breast milk. Review

La leche materna donada es un recurso de alto valor que puede ser utilizado para la alimentación de neonatos hospitalizados y a término, por tanto, garantizar su inocuidad es imperativo. Esta revisión de literatura reúne los principales peligros de naturaleza física, química y microbiológica identificados en leche materna, con la intención de proveer una referencia que los consolide de tal forma que la información pueda ser utilizada por bancos de leche humana, gobiernos y agencias regulatorias para establecer mecanismos para su prevención y control. Se realizó una revisión de literatura entre agosto del 2021 y octubre del 2022, utilizando buscadores y descriptores específicos para peligros de transmisión alimentaria en leche materna. Se incluyeron estudios publicados en español o en inglés. Se identificaron 31 agentes biológicos patógenos incluyendo bacterias, virus y parásitos. Como peligros químicos se reportaron medicamentos, drogas, cafeína, infusiones herbales, micotoxinas, alérgenos, especias, suplementos nutricionales, contaminantes ambientales y desinfectantes. Se alerta sobre la presencia potencial de plástico y vidrio de tamaño menor a 7 mm proveniente del ambiente de extracción y recipientes. La presencia de peligros microbiológicos y químicos en leche materna puede darse por transmisión vertical, temperaturas inadecuadas durante el almacenamiento y contaminación en el proceso. La presencia de peligros físicos se relaciona con la manipulación de los implementos en etapas posteriores a la extracción. Se requiere prestar atención a los hábitos de la madre para prevenir peligros químicos, así como más investigación relacionada con micotoxinas en leche materna(AU)

Donated breast milk is a highvalue resource which can be used to feed hospitalized neonates and full-term infants, therefore, ensuring its safety is imperative. This literature review presents the main hazards of physical, chemical and microbiological nature identified in human milk, with the intention of providing a reference that consolidates the reported hazards reported, so the information can be used by human milk banks, governments and regulatory agencies to establish prevention and control mechanisms. A literature review was carried out between August 2021 and October 2022, using search engines and specific descriptors for foodborne hazards in breast milk. Studies published in Spanish and English were considered. 31 pathogenic biological agents including bacteria, viruses and parasites were identified. Medications, drugs, caffeine, herbal infusions, mycotoxins, allergens, spices, nutritional supplements, contaminants of environmental origin and disinfectants were reported as chemical hazards. No physical hazards were identified, however the potential presence of plastic and glass smaller than 7 mm from the extraction environment or containers is alerted. Presence of microbiological and chemical hazards can be due to vertical transmission, inadequate temperature of storing, contamination during extraction, packaging, and infant feeding. Whereas presence of physical hazards is related to implements handling after extraction. Attention to hygiene and habits of the mother to prevent chemical hazards and further research related to mycotoxins in human milk is required(AU)

Recruitment and retention of general practitioners in European medical deserts: a systematic review.

INTRODUCTION: Despite policies aiming at universal health coverage by ensuring availability and accessibility of general practitioners (GPs), medically underserved areas are still present in Europe. This systematic review aims to summarize and compare literature on interventions and their potential effectiveness of GP recruitment and retention in these underserved areas ('medical deserts') from 2011 onwards. METHODS: PubMed and Embase were used to identify publications, applying a two-stage selection process. All types of study designs, published in the past 10 years, were included if they discussed a possible intervention for GP recruitment or retention covering an underserved area in an EU-27/EEA/EFTA country (part of the European Union, the European Economic Area or the European Free Trade Association). Exclusion criteria were abstracts or full text not available, conference abstracts, poster presentations, books or overlapping secondary literature. Identified interventions were classified into four categories: 'education', 'professional and personal support', 'financial incentives' and 'regulation'. Eligible articles were critically appraisal by two authors (JB, LF), independently, by using the Joanna Briggs Institute checklist. RESULTS: Of the 294 publications initially retrieved, 25 publications were included. Of them, 14 (56%) described educational interventions, 13 (52%) professional and personal support, and 11 (40%) financial or regulatory interventions. Overlapping categories were often described (56%). The effectiveness of educational or supportive interventions has mainly been evaluated cross-sectionally, whereby causal inference on future GP availability cannot be implied. Few and mixed results were found for the effectiveness of financial and regulatory interventions, because period co-interventions were not taken into account during the study. CONCLUSION: In the past 10 years, educational and supportive interventions to improve GP recruitment and retention have been reported most frequently, but often overlapping strategies are seen. While multiple strategies have potential to be effective, their limited evaluation makes it difficult to provide suggestions for policymakers to adapt their GP recruitment and retention strategies aiming at a best-practice approach in European medical deserts.

Characteristics of medical deserts and approaches to mitigate them: a scoping review.

INTRODUCTION: Medical deserts are increasingly considered problematic and many countries employ a multitude of actions and initiatives to achieve a better distribution of the health workforce (HWF). This study systematically maps research and provides an overview of the definitions/characteristics of medical deserts. It also identifies contributing factors and approaches to mitigate medical deserts. METHODS: Embase, MEDLINE, CINAHL, Web of Science Core Collection, Google Scholar and The Cochrane Library were searched from inception to May 2021. Studies reporting primary research on definitions, characteristics, contributing factors and approaches to mitigate medical deserts were included. Two independent reviewers assessed studies for eligibility, extracted data and clustered studies. RESULTS: Two-hundred and forty studies were included (49% Australia/New Zealand, 43% North America, 8% Europe). All used observational designs except for five quasi-experimental studies. Studies provided definitions (n=160), characteristics (n=71), contributing/associated factors (n=113), and approaches to mitigate medical deserts (n=94). Most medical deserts were defined by the density of the population in an area. Contributing/associated factors consisted in sociodemographic/characteristics of HWF (n=70), work-related factors (n=43) and lifestyle conditions (n=34). Approaches focused on training adapted to the scope of rural practice (n=79), HWF distribution (n=3), support and infrastructure (n=6) and innovative models of care (n=7). DISCUSSION: Our study provides the first scoping review on definitions, characteristics, contributing/associated factors and approaches to mitigate medical deserts. We identified gaps such as the scarcity of longitudinal studies to investigate factors contributing to medical deserts, and interventional studies to evaluate the effectiveness of approaches to mitigate medical deserts.

Anticholinergic burden measures, symptoms, and fall-associated risk in older adults with polypharmacy: Development and validation of a prognostic model.

BACKGROUND: Anticholinergic burden has been associated with adverse outcomes such as falls. To date, no gold standard measure has been identified to assess anticholinergic burden, and no conclusion has been drawn on which of the different measure algorithms best predicts falls in older patients from general practice. This study compared the ability of five measures of anticholinergic burden to predict falls. To account for patients' individual susceptibility to medications, the added predictive value of typical anticholinergic symptoms was further quantified in this context. METHODS AND FINDINGS: To predict falls, models were developed and validated based on logistic regression models created using data from two German cluster-randomized controlled trials. The outcome was defined as "≥ 1 fall" vs. "no fall" within a 6-month follow-up period. Data from the RIME study (n = 1,197) were used in model development, and from PRIMUM (n = 502) for external validation. The models were developed step-wise in order to quantify the predictive ability of anticholinergic burden measures, and anticholinergic symptoms. In the development set, 1,015 patients had complete data and 188 (18.5%) experienced ≥ 1 fall within the 6-month follow-up period. The overall predictive value of the five anticholinergic measures was limited, with neither the employed anticholinergic variable (binary / count / burden), nor dose-dependent or dose-independent measures differing significantly in their ability to predict falls. The highest c-statistic was obtained using the German Anticholinergic Burden Score (0.73), whereby the optimism-corrected c-statistic was 0.71 after interval validation using bootstrapping and 0.63 in the external validation. Previous falls and dizziness / vertigo had the strongest prognostic value in all models. CONCLUSIONS: The ability of anticholinergic burden measures to predict falls does not appear to differ significantly, and the added value they contribute to risk classification in fall-prediction models is limited. Previous falls and dizziness / vertigo contributed most to model performance.

Characteristics of Medical Deserts and Approaches to Mitigate Their Health Workforce Issues: A Scoping Review of Empirical Studies in Western Countries.

BACKGROUND: Medical deserts are considered a problematic issue for many Western countries which try to employ multitude of policies and initiatives to achieve a better distribution of their health workforce (HWF). The aim of this study was to systematically map research and provide an overview of definitions, characteristics, contributing factors and approaches to mitigate medical deserts within the European Union (EU)-funded project "ROUTE-HWF" (a Roadmap OUT of mEdical deserts into supportive Health WorkForce initiatives and policies). METHODS: We performed a scoping review to identify knowledge clusters/research gaps in the field of medical deserts focusing on HWF issues. Six databases were searched till June 2021. Studies reporting primary research from Western countries on definitions, characteristics, contributing factors, and approaches were included. Two independent reviewers assessed studies for eligibility, extracted data and clustered studies according to the four defined outcomes. RESULTS: Two-hundred and forty studies were included (n=116, 48% Australia/New Zealand; n=105, 44% North America; n=20, 8% Europe). All used observational designs except for five quasi-experimental studies. Studies provided definitions (n=171, 71%), characteristics (n=95, 40%), contributing factors (n=112, 47%), and approaches to mitigate medical deserts (n=87, 36%). Most medical deserts were defined by the density of the population in an area. Contributing factors to HWF issues in medical deserts consisted in work-related (n=55, 23%) and lifestyle-related factors (n=33, 14%) of the HWF as well as sociodemographic characteristics (n=79, 33%). Approaches to mitigate them focused on training adapted to the scope of rural practice (n=67, 28%), HWF distribution (n=3, 1%), support/infrastructure (n=8, 3%) and innovative models of care (n=7, 3%). CONCLUSION: Our study provides the first scoping review that presents and categorizes definitions, characteristics, contributing factors, and approaches to mitigate HWF issues in medical deserts. We identified gaps such as the scarcity of longitudinal studies to investigate the impact of factors contributing to medical deserts, and interventional studies to evaluate the effectiveness of approaches to mitigate HWF issues.

Exploring the Effectiveness of Self-Management Interventions in Type 2 Diabetes: A Systematic Review and Network Meta-Analysis.

BACKGROUND: Chronic diseases are a leading cause of global morbidity and mortality. In response to this challenge, self-management interventions (SMIs) have emerged as an essential tool in improving patient outcomes. However, the diverse and complex nature of SMIs pose significant challenges in measuring their effectiveness. This work aims to investigate the comparative effectiveness of SMIs on Type 2 diabetes mellitus (T2DM) outcomes. METHODS: A rigorous analytical framework was employed to assess the relative effectiveness of different SMIs, encompassing both pairwise and network meta-analysis (NMA), as well as component network meta-analysis (CNMA). Various outcomes were considered, including glycated hemoglobin (HbA1c) control, body mass index (BMI) reduction and low-density lipoprotein (LDL) cholesterol. Visualization tools were also utilized to enhance the interpretation of results. RESULTS: SMIs were found promising in improving clinical outcomes and patient-reported measures. However, considerable heterogeneity and inconsistency across studies challenged the validity of NMA results. CNMA along with various visualization tools offered insights into the contributions of individual SMI components, highlighting the complexity of these interventions. DISCUSSION/CONCLUSIONS: SMIs represent a valuable approach to managing chronic conditions, but their effectiveness is context-dependent. Further research is needed to elucidate the contextual factors influencing SMI outcomes. This work contributes to a comprehensive understanding of SMIs' role in T2DM management, aiming to aid decision-makers, clinicians, and patients in selecting tailored interventions.

Using a Taxonomy to Systematically Identify and Describe Self-Management Interventions Components in Randomized Trials for COPD.

Self-management interventions (SMIs) may improve outcomes in Chronic Obstructive Pulmonary Disease (COPD). However, accurate comparisons of their relative effectiveness are challenging, partly due to a lack of clarity and detail regarding the intervention content being evaluated. This study systematically describes intervention components and characteristics in randomized controlled trials (RCTs) related to COPD self-management using the COMPAR-EU taxonomy as a framework, identifying components that are insufficiently incorporated into the design of the intervention or insufficiently reported. Overall, 235 RCTs published between 2010 and 2018, from a systematic review were coded using the taxonomy, which includes 132 components across four domains: intervention characteristics, expected patient (or caregiver) self-management behaviours, patient relevant outcomes, and target population characteristics. Risk of bias was also assessed. Interventions mainly focused on physical activity (67.4%), and condition-specific behaviours like breathing exercise (63.5%), self-monitoring (50.8%), and medication use (33.9%). Support techniques like education and skills-training, self-monitoring, and goal setting (over 35% of the RCTs) were mostly used for this. Emotional-based techniques, problem-solving, and shared decision-making were less frequently reported (less than 15% of the studies). Numerous SMIs components were insufficiently incorporated into the design of COPD SMIs or insufficiently reported. Characteristics like mode of delivery, intensity, location, and providers involved were often not described. Only 8% of the interventions were tailored to the target population's characteristics. Outcomes that are considered important by patients were hardly taken into account. There is still a lot to improve in both the design and description of SMIs for COPD. Using a framework such as the COMPAR-EU SMI taxonomy may contribute to better reporting and to better informing of replication efforts. In addition, prospective use of the taxonomy for developing and reporting intervention content would further aid in building a cumulative science of effective SMIs in COPD.

La mastectomía como medida de reducción de riesgo de cáncer de mama / Risk-reducing mastectomy in breast cancer

Objetivos: Evaluar las mastectomías reductoras de riesgo realizadas y analizar las indicaciones y resultados según las características individuales, oncológicas y quirúrgicas de nuestras pacientes.MétodosEstudio observacional retrospectivo de todas las mastectomías con reconstrucción inmediata en mamas sanas realizadas desde 2013 a 2019. Se dividieron las pacientes en tres grupos: I) riesgo genético de cáncer de mama, II) cáncer de mama diagnosticado y III) antecedente de cáncer de mama.ResultadosSe realizaron 56 mastectomías reductoras de riesgo a 46 pacientes, 15% grupo I, 50% grupo II y 35% grupo III, pero tras estudios diferidos, 20 pacientes (43%) presentaban mutación genética. La media de edad en este subgrupo fue de 40 años y con predominio de tumores HER2+ (40% frente al 12%, p=0,164). En el grupo III observamos más complicaciones inmediatas (31%, p=0,014) y tardías (69%, p=0,027) relacionadas con la reconstrucción protésica, y más evidente en mamas que tuvieron enfermedad (73% frente al 39% sanas, p=0,002). Se encontró relación entre contractura capsular y la radioterapia postoperatoria (p=0,008) y entre necrosis y radioterapia preoperatoria (p=0,001). Se reintervino al 7% por complicaciones en mastectomías profilácticas. No hemos tenido recidivas locales.ConclusionesConsideramos justificada la mastectomía reductora de riesgo realizada a mujeres jóvenes con mutación genética y a pacientes con cáncer precoz, HER2+ y riesgo familiar. En pacientes ya tratadas por cáncer, el riesgo de complicaciones supera el valor profiláctico de la técnica. La reconstrucción mamaria es la principal responsable de complicaciones postoperatorias y las pacientes deben ser plenamente conscientes de ello. (AU)

Objectives: To evaluate the risk-reducing mastectomies performed and to analyse the indications and results according to the individual, oncological and surgical characteristics of our patients.MethodsRetrospective observational study of all mastectomies with immediate reconstruction in healthy breasts performed from 2013 to 2019. The patients were divided into three groups: I) genetic risk of breast cancer, II) diagnosed breast cancer and III) history of cancer breast.ResultsA total of 56 risk-reducing mastectomies were performed in 46 patients, 15% in group I, 50% in group II and 35% in group III. After deferred studies, 20 (43%) patients had a genetic mutation. This subgroup had an average age of 40 years and a predominance of HER2+ tumours (40% versus 12%, p=0.164). In group III, we observed more immediate (31%, p=0.014) and late (69%, p=0.027) complications related to prosthetic reconstruction, which were more evident in breasts with disease (73% versus 39% healthy, p=0.002). A relationship was found between capsular contracture and postoperative radiotherapy (p=0.008) and between necrosis and preoperative radiotherapy (p=0.001). Reoperation was required in 7% for complications of prophylactic mastectomies. There were no local relapses.ConclusionsWe consider risk-reducing mastectomy to be justified in young women with a genetic mutation and in patients with early cancer, HER2+ and family risk. In patients already treated for cancer, the risk of complications exceeds the prophylactic value of the technique. Breast reconstruction is primarily responsible for postoperative complications and patients should be fully aware of this. (AU)

Predicting negative health outcomes in older general practice patients with chronic illness: Rationale and development of the PROPERmed harmonized individual participant data database.

The prevalence of multimorbidity and polypharmacy increases significantly with age and are associated with negative health consequences. However, most current interventions to optimize medication have failed to show significant effects on patient-relevant outcomes. This may be due to ineffectiveness of interventions themselves but may also reflect other factors: insufficient sample sizes, heterogeneity of population. To address this issue, the international PROPERmed collaboration was set up to obtain/synthesize individual participant data (IPD) from five cluster-randomized trials. The trials took place in Germany and The Netherlands and aimed to optimize medication in older general practice patients with chronic illness. PROPERmed is the first database of IPD to be drawn from multiple trials in this patient population and setting. It offers the opportunity to derive prognostic models with increased statistical power for prediction of patient-relevant outcomes resulting from the interplay of multimorbidity and polypharmacy. This may help patients from this heterogeneous group to be stratified according to risk and enable clinicians to identify patients that are likely to benefit most from resource/time-intensive interventions. The aim of this manuscript is to describe the rationale behind PROPERmed collaboration, characteristics of the included studies/participants, development of the harmonized IPD database and challenges faced during this process.

A prognostic model predicted deterioration in health-related quality of life in older patients with multimorbidity and polypharmacy.

OBJECTIVES: To develop and validate a prognostic model to predict deterioration in health-related quality of life (dHRQoL) in older general practice patients with at least one chronic condition and one chronic prescription. STUDY DESIGN AND SETTING: We used individual participant data from five cluster-randomized trials conducted in the Netherlands and Germany to predict dHRQoL, defined as a decrease in EQ-5D-3 L index score of ≥5% after 6-month follow-up in logistic regression models with stratified intercepts to account for between-study heterogeneity. The model was validated internally and by using internal-external cross-validation (IECV). RESULTS: In 3,582 patients with complete data, of whom 1,046 (29.2%) showed deterioration in HRQoL, and 12/87 variables were selected that were related to single (chronic) conditions, inappropriate medication, medication underuse, functional status, well-being, and HRQoL. Bootstrap internal validation showed a C-statistic of 0.71 (0.69 to 0.72) and a calibration slope of 0.88 (0.78 to 0.98). In the IECV loop, the model provided a pooled C-statistic of 0.68 (0.65 to 0.70) and calibration-in-the-large of 0 (-0.13 to 0.13). HRQoL/functionality had the strongest prognostic value. CONCLUSION: The model performed well in terms of discrimination, calibration, and generalizability and might help clinicians identify older patients at high risk of dHRQoL.

Temporal dynamics of infection of cockles Cerastoderma edule with the protistan parasite Minchinia tapetis (Rhizaria: Haplosporida) in Galicia (NW Spain).

Uninucleate and binucleate cells and multinucleate plasmodia of a haplosporidan-like protist associated with heavy haemocytic infiltration were observed in histological sections of cockles, Cerastoderma edule, from the Ría de Noia (Galicia, NW Spain) in the course of a cockle health surveillance programme. Molecular assays provided identification of this protist as Minchinia tapetis, which we thus record from a new host. Prevalence of M. tapetis as high as 93% was recorded but infection intensity was low to moderate, never heavy, and abnormally high cockle mortality was not observed in the ria by shellfishers. A significant positive correlation was found between M. tapetis prevalence and sea water temperature. Sea water temperature increase associated with climate change might contribute to increase the prevalence of this infection in cockles and, as a consequence, this parasite may be considered a threat for cockle production.
