Improvements in habitability and housing satisfaction after dwelling regeneration in social housing complexes. The RUCAS study.

Housing is a pressing problem worldwide and a key determinant of health and wellbeing. The right to adequate housing, as a pillar of the right to an adequate standard of living, means more than a roof to live under. Adequate means the dwelling must fulfill material functions and psychosocial functions, thus contributing to dwellers health and wellbeing. Social housing policies aim to fulfill the right to housing, but frequently fail in fulfilling the right to it being adequate. This study capitalizes on the implementation of a national urban regeneration program in two social housing villas in central Chile (one in Santiago, in the central valley, the other in Viña del Mar, a coastal city) to run a natural experiment assessing the impact of dwelling renovation on several dimensions of perceived habitability and housing satisfaction among the -mostly female-household homemakers. We use 5 waves of survey data collected with a step-wedge design to estimate the association between a time-varying exposure status (the intervention) and 7 binary outcomes for habitability and 5 for housing dissatisfaction, including overall housing satisfaction. We use Poisson regression models with robust variance and a random intercept at the respondent level. At baseline, reports of poor habitability and dissatisfaction across all features were markedly high, the highest levels of dissatisfaction being with acoustic insulation and dwelling size in both villas, and with indoor temperature in Santiago. The intervention resulted in statistically significant and markedly large improvements in reported habitability and dissatisfaction relative to those housing components targeted by the intervention, as well as with overall dwelling satisfaction in both study cases. Implications are, first, that the policy response to quantitative housing deficits must not overlook housing quality; second, that housing renovation appears as a promising intervention for qualitative housing crises; third, that while improvements in habitability and satisfaction are specific to the interventions in place, overall housing satisfaction can improve in more limited, tailored, dwelling renovation interventions. Social housing renovation in Latin America appears as a promising intervention to improve quality of life among the urban poor dwellers and reduce inequalities in health related to housing conditions.

Detection and characterization of Deformed Wing Virus (DWV) in apiaries with stationary and migratory management in the province of Entre Ríos, Argentina.

In Argentina, migratory activity in search of floral diversity has become a common approach to maximizing honey production. The Entre Ríos province possesses a floral diversity that allows beekeepers to perform migratory or stationary management. Beyond the impact caused by transhumance, migratory colonies in this province start and end the season in monoculture areas. To study the effect of these practices on viral infection, we assayed for the presence, abundance and genetic characterization of the Deformed Wing Virus (DWV) in honey bees from apiaries with both types of management. In migratory apiaries, DWV was detectable in 86.2% of the colonies at the beginning of the season (September 2018), and 66% at the end of the season (March 2019). On the other hand, DWV was detected in 44.11% and 53.12% of stationary samples, at the beginning and the end of the season, respectively. Sequence analysis from migratory and stationary colonies revealed that all samples belonged to DWV-A type. The highest viral loads were detected in migratory samples collected in September. Higher DWV presence and abundance were associated with migratory management and the sampling time. Based on our findings we propose that the benefit of migration to wild flowering areas can be dissipated when the bee colonies end the season with monoculture.

Cyanoacrylate versus suture as flap closure methods in mandibular third molar surgery: a split-mouth randomized controlled clinical study.

BACKGROUND: Sutures have been the standard flap closure method of choice following mandibular third molar surgery but can lead to some complications. Tissue adhesives, including cyanoacrylate, have emerged as alternative flap closure method in this surgery to overcome such drawbacks. However, limited clinical trials can be found. Therefore, the aim of this clinical study was to compare two methods of flap closure in mandibular third molar surgery, cyanoacrylate and 4/0 silk sutures, by assessing post-operative outcome measures (pain, swelling, trismus, and healing) and patient-reported outcome measures (PROMs). MATERIAL AND METHODS: A randomized split-mouth clinical trial was designed, in which mandibular third molar (M3M) extractions were performed, where the control side flap was closed with 4/0 silk sutures and the test side flap with cyanoacrylate. Swelling, pain, trismus, healing, and PROMs were recorded post-operatively. These variables were analyzed by means of the nonparametric Mann-Whitney U test, using SPSS statistical software version 28.0.0 (IBM® SPSS®, Chicago, IL, USA). For all results, a 95% confidence interval was recorded (significance level p < 0.05, two-tailed). RESULTS: A total of 17 patients were recruited and 34 mandibular third molar extractions were performed. No statistically significant differences were found in terms of swelling, pain, trismus, healing, and PROMs between both groups (p<0.05). CONCLUSIONS: No statistically significant differences were found between flap closure with 4/0 silk sutures and cyanoacrylate, in terms of surgical post-operative outcomes and PROMs. However, further studies with larger sample sizes are required to be able to affirm it with greater certainty.

Titanium mesh for guided bone regeneration: a systematic review.

This systematic review aimed to evaluate results reported in the literature regarding the success rate of the titanium mesh technique for the placement of dental implants. The topic focused on titanium mesh used as a physical barrier for ridge reconstruction in cases of partial or total edentulism. The authors conducted an electronic search of four databases up to October 2023. Six articles fulfilled the inclusion criteria and were analysed. A total of 100 titanium meshes with a minimum of 4.6 months follow up after surgery were studied, and 241 implants were placed. The review shows that the use of titanium mesh is a predictable method for the rehabilitation of complex atrophic sites. Further investigation generating long-term data is needed to confirm these findings.

[Ethics of care: Assessment of the ethical issues in the protocols or consensuses on mechanical restraint in force in Spain]. / Ética de los cuidados: valoración de los contenidos éticos en los protocolos o consensos de contención mecánica vigentes en España.

INTRODUCTION: Mechanical restraints are widely used in health care practice, despite the numerous ethical conflicts they raise. The aim of this study is to evaluate the ethical considerations contemplated in the current protocols on mechanical restraint in Spain. METHOD: Systematic review in PubMed, WOS and Scopus, Google and Google Scholar. An ad hoc list of 30 items was used to evaluate the ethical content of the protocols. The quality of guidelines was assessed with AGREE II. RESULTS: The need for informed consent (IC) is reflected in 72% of the documents, the IC model sheet is included in only 41% of them, the rest of the analyzed characteristics on IC are fulfilled in percentages between 6% (the document includes the need to reevaluate the indication for IC) and 31% (the document contemplates to whom it should be requested). More than 20 ethical contents are reflected in 31% of them and less than 10 in 19% of the guidelines. The quality of the guides, according to AGREE II, ranged from 27 to 116 points (maximum possible 161), with a mean score of 68.7. Only 9% of the documents were classified as high quality. Finally, the correlation between ethical content and quality measured with AGREE II was 0.75. CONCLUSIONS: The variability of ethical contents in guidelines on mechanical restraints is very high. The ethical requirements to be included in protocols, consensus or Clinical Practice Guidelines should be defined.

Awareness and Self-Reported Knowledge and Training on Nutrition in Older People among Primary Care Practitioners.

OBJECTIVES: To assess the awareness and training of primary care physicians on nutrition in older patients. DESIGN: Observational, real-world data survey. SETTING: Primary Care. PARTICIPANTS: One hundred sixty-two physicians, generalists and specialists, working in primary care. MEASUREMENTS: Participants received an online questionnaire with 18 questions concerning the importance of nutrition, degree of knowledge, needs, and training in nutrition. The results were evaluated using univariate descriptive analysis, with a percentage for each chosen answer. Logistic regression models were used to evaluate if answers were related to training in nutrition and professional experience. RESULTS: 43.2% of participants reported that nutrition is very important in individuals over 65 years old, and 90% were aware of the importance of nutrition in healthy aging. Nutritional problems affect 30 to 50% of patients, according to 44.7% of participants. 89.2% agree about the need for nutritional assessment in older patients; however, the professionals believe they should be better prepared. Two out of three respondents consider the training received in nutrition during their undergraduate course or continuing medical education as deficient. Time of professional practice was mainly associated with conceptual facts, while continuing medical education did with practical issues, mainly the use of screening and diagnostic tools [FRAIL (OR: 3.16; 95%IC: 1.55-6.46), MNA-SF (OR: 6.455; 95%IC: 2.980-13.981) and SARC-F (OR: 3.063; 95%IC: 1.284-7.309)]. CONCLUSION: Although primary care professionals are aware of the importance of nutrition in older patients, there are still gaps in daily practice that could be improved by developing educational strategies.

Cognitive rehabilitation program in patients with multiple sclerosis: A pilot study / Programa de rehabilitación cognitiva para pacientes con esclerosis múltiple: estudio piloto

Introduction In recent years, there has been an increase of studies dedicated to cognitive rehabilitation in patients with multiple sclerosis (MS); however, few of these analyze the impact on such variables as cognitive reserve. The study aims to explore the effects of a cognitive rehabilitation program comprising a combination of cognitive and physical exercises, as well as group sessions to improve cognitive performance, emotional state, and cognitive reserve index. Method Fifty patients with MS were subdivided into 2 groups: the control group, which performed aerobic exercise (n = 25), and the experimental group (n = 25), which participated in the integrated cognitive rehabilitation program (ICRP). All participants were evaluated 3 times (baseline, post-treatment, and long-term) with the Brief Repeatable Battery of Neuropsychological Tests, Cognitive Reserve Scale, Beck Depression Inventory, and a scale evaluating trait and state anxiety. Results Compared with the control group, patients in the experimental group showed improvements in cognitive function, with significant changes in measures of information processing speed, attention, memory, cognitive reserve index, and long-term mood. Conclusions The ICRP was effective in improving cognitive and emotional function in MS, and increased the cognitive reserve index. (AU)

Fumadores y riesgo de muerte hospitalaria por COVID calculado con el procesamiento de lenguaje natural de SAVANA en el ámbito de Castilla-La Mancha / Smokers and risk of hospital death by COVID calculated with SAVANA's natural language processing in the Castilla-La Mancha area

Introducción Durante la pandemia de COVID se especuló que los pacientes con el virus que tenían relación con el tabaco podrían tener una menor probabilidad de agravamiento de la enfermedad o muerte. Para evaluar si existe una asociación entre el tabaquismo y el riesgo de mortalidad intrahospitalaria se utiliza la tecnología de Big Data y Procesamiento del Lenguaje Natural (PLN) de SAVANA. Método Se llevó a cabo un estudio de cohortes retrospectivo, observacional y sin intervención basado en datos de vida real extraídos de registros médicos de toda Castilla-La Mancha utilizando las técnicas de PLN e inteligencia artificial desarrolladas por SAVANA. El estudio abarcó toda la población de esta Comunidad con historia clínica electrónica en SESCAM que presentara diagnóstico de COVID desde el 1 de marzo de 2020 al 28 de febrero de 2021. Resultados Los fumadores tienen mayor porcentaje de factores de riesgo cardiovascular (hipertensión arterial, dislipemia y diabetes), EPOC, asma, EPID, CI, ECV, TEP, cáncer en general y cáncer de pulmón en particular, bronquiectasias, insuficiencia cardíaca y antecedentes de neumonía, de forma significativa (p<0,0001). Los pacientes exfumadores, fumadores y no fumadores tienen una diferencia de edad significativa. En cuanto a las muertes hospitalarias, fueron más frecuentes en el caso de los exfumadores, siguiendo los fumadores y luego los no fumadores (p<0,0001). Conclusión Existe un mayor riesgo de mortalidad intrahospitalaria en los pacientes infectados por SARS-CoV-2 que sean fumadores activos o hayan fumado en el pasado. (AU)

Introduction During the COVID pandemic, it was speculated that patients with the virus who were smoking-related might have a lower likelihood of disease exacerbation or death. To assess whether there is an association between smoking and risk of in-hospital mortality, SAVANA's big data and natural language processing (NLP) technology is used. Method A retrospective, observational, non-interventional cohort study was conducted based on real-life data extracted from medical records throughout Castilla-La Mancha using natural language processing and artificial intelligence techniques developed by SAVANA. The study covered the entire population of this region with Electronic Medical Records in SESCAM presenting with a diagnosis of COVID from March 1, 2020 to February 28, 2021. Results Smokers had a significantly higher percentage of cardiovascular risk factors (hypertension, dyslipidemia and diabetes), COPD, asthma, IDP, IC, CVD, PTE, cancer in general and lung cancer in particular, bronchiectasis, heart failure and a history of pneumonia (P<.0001). Former smokers, current smokers and non-smokers have a significant age difference. As for in-hospital deaths, they were more frequent in the case of ex-smokers, followed by smokers and then non-smokers (P<.0001). Conclusion There is an increased risk of dying in hospital in SARS-CoV-2-infected patients who are active smokers or have smoked in the past. (AU)

Clinical results of total hip arthroplasty assisted by robotic arm in Spain: Preliminary study. / Resultados clínicos de artroplastia total de cadera asistida por brazo robótico en España: estudio preliminar.

OBJECTIVES: Clinical, radiological and functional results of the first Spanish series of patients undergoing total hip arthroplasty assisted by Mako® (Stryker) robotic arm at the Hospital Clínico San Carlos (HCSC) in Madrid. MATERIAL AND METHODS: Prospective and descriptive study analyzing the first 25 patients who underwent robotic-assisted THA at the HCSC, with a minimum follow-up of 4months. Demographics, imaging studies (Mako® processing, Rx and CT), clinical parameters, functionality (modified Harris) and associated complications were evaluated. RESULTS: Average age was 67.2years (min 47, max 88), being 56% male population sample. 88% involves primary coxarthrosis, 4% post-traumatic coxarthrosis, 4% secondary avascular necrosis and 4% secondary femoroacetabular impingement. Average surgery time was 116.9min (min 92, max 150). The average time of the first five surgeries was 122.6min, and, regarding the last five interventions, it was 108.2min. Found medical intraoperative complications were four intraoperative markers loss. Average admission time was 4.4days (min 3, max 7), with an average postoperative hemoglobin decrease of 3.08±1.08g/dL, requiring a transfusion in 12% of the cases. Three medical complications have been registered in the meantime of the admission, with a relevant case of a confusional syndrome and a fall, which resulted in a non-displaced AG1 periprosthetic fracture. The analysis of the positioning of registered implants with Mako® system shows 40.55±1.53 acetabular inclination degrees and 12.2±3.6 acetabular anteversion degrees. The postoperative image study carried out on patients, are consistent with Mako® s results, as it shows an acetabular inclination of 41.2±1.7 in Rx, as well as acetabular anteversion of 16±4.6 in CT. Hip length variance ranges depending on preoperative values of 3.91mm (SD: 3.9; min -12, max 3) to 1.29mm (SD: 1.96) after surgery registered with Mako®, with an increase of an average hip length of 5.64mm (SD: 3.35). Rx simple study results show a postoperative difference between both hips of 0.5±3.08mm, which is consistent with Mako® results. Native femoral offset was stable after surgery with a showing difference both pre and post operative of the intervened hip of 0.1mm (SD: 3.7), registered with Mako®. Preoperatory modified Harris punctuation was 41.6±13.3, improving to postoperative values of 74.6±9.7 after four months since the surgery. No complications were registered in immediate postoperative (4month). CONCLUSIONS: Total hip arthroplasty robot-assisted achieves an adequate precision and repeatability of the implant positioning and the postoperative hip dysmetry without showing an increase of associated complications to the technique applied. Surgery time, complications and functional results in a short-time period are similar to conventional techniques applied to great series previously published.

Is it possible to predict neurosensory alterations in impacted lower third molar removal based on preoperative imaging procedures? A prospective cohort study.

BACKGROUND: Surgical extraction of the lower third molar (LTM) may trigger neurosensory injury of the inferior alveolar nerve, making extraction a real challenge. This study set out to assess whether is it possible to predict neurosensory alterations from preoperative imaging. MATERIAL AND METHODS: A total of 99 patients underwent 124 impacted lower third molar (ILTM) surgeries. Prior to surgery, panoramic and CBCT images were evaluated in an attempt to predict a neurosensory disturbance. Preoperative data (ILTM position, panoramic radiograph signs, inferior alveolar nerve (IAN) location and its contact with the ILTM roots) and intra/postoperative findings (extraction difficulty and sensitivity alterations) were recorded. Descriptive and bivariate data analysis was performed. Statistical comparison applied the chi-square test, Fisher test, and one-way ANOVA test. Statistical significance was established with a confidence interval (CI) of 95%. RESULTS: In 4.03% of cases, patients experienced neurosensory alterations. Of 124 ILTM positions in panoramic radiographs, 76 cases were considered to exhibit a potential neurosensory risk as they presented two or more types of superimposed relationships between ILTM and mandibular canal. Of these, alterations were reported in only three cases (3.95%). Of the 48 remaining ILTM images presenting only one sign, neurosensory alterations were observed in two cases (4.17%). No permanent alterations were recorded in any of the five cases observed. CONCLUSIONS: Within the limitations of the present study, prediction of neurosensory alterations prior to ILTM extraction by means of preoperative imaging did not show a significant statistical correlation with post-surgical incidence. Nevertheless, interruption of the canal´s white line (ICWL) or a diversion of the canal (DC) may predict an increased risk of IAN injury.

[Translated article] Clinical results of total hip arthroplasty assisted by robotic arm in Spain: Preliminary study.

OBJECTIVES: Clinical, radiological and functional results of the first Spanish series of patients undergoing total hip arthroplasty assisted by Mako® (Stryker) robotic arm at the Hospital Clínico San Carlos (HCSC) in Madrid.

Gamma-ray sources imaging and test-beam results with MACACO III Compton camera.

Hadron therapy is a radiotherapy modality which offers a precise energy deposition to the tumors and a dose reduction to healthy tissue as compared to conventional methods. However, methods for real-time monitoring are required to ensure that the radiation dose is deposited on the target. The IRIS group of IFIC-Valencia developed a Compton camera prototype for this purpose, intending to image the Prompt Gammas emitted by the tissue during irradiation. The system detectors are composed of Lanthanum (III) bromide scintillator crystals coupled to silicon photomultipliers. After an initial characterization in the laboratory, in order to assess the system capabilities for future experiments in proton therapy centers, different tests were carried out in two facilities: PARTREC (Groningen, The Netherlands) and the CNA cyclotron (Sevilla, Spain). Characterization studies performed at PARTREC indicated that the detectors linearity was improved with respect to the previous version and an energy resolution of 5.2 % FWHM at 511 keV was achieved. Moreover, the imaging capabilities of the system were evaluated with a line source of 68Ge and a point-like source of 241Am-9Be. Images at 4.439 MeV were obtained from irradiation of a graphite target with an 18 MeV proton beam at CNA, to perform a study of the system potential to detect shifts at different intensities. In this sense, the system was able to distinguish 1 mm variations in the target position at different beam current intensities for measurement times of 1800 and 600 s.
