A quality improvement intervention on surgical prophylaxis impact in antibiotic consumption and cost in selected surgical procedures.

BACKGROUND: Improper compliance with antibiotic prophylaxis (AP) in surgery is associated with an increased risk of surgical site infection (SSI), and impacts the efficiency of healthcare. OBJECTIVE: Evaluate the impact of an intervention in compliance with AP in selected surgical procedures and its effect on antibiotic consumption and cost. METHODS: A prospective interventional study was performed in a community hospital from January to December 2022. The baseline period was considered January-April 2022 and the intervention period May-December 2022. All patients who underwent cesarean section, appendectomies, hernia surgery, open reduction and internal fixation (ORIF), abdominoplasty, and cholecystectomy during the study period were selected. The intervention includes staff education, pharmacy interventions, monitoring the quality of prescriptions and feedback, and improved role of anesthesia staff, and department champions. RESULTS: The study involved 192 and 617 surgical procedures in the baseline and intervention periods respectively. The compliance with timing, selection, dose, and discontinuation achieved 100%, 99.2%, and 97.6% from baseline figures of 92.7%, 95.8%, and 81.3%, respectively. The antibiotic consumption was reduced by 55.1% during the intervention with a higher contribution of other antibiotics (94.1% reduction) in comparison with antibiotics as per policy (31.2% reduction). The cost was reduced by 47.2% (antibiotic as per policy 31.9%, other antibiotics 94.2%). CONCLUSION: The implemented strategy was effective in improving the quality of antibiotic prophylaxis with a significant impact in reducing antibiotic consumption and cost.

"It doesn't exist, only other people have it, or it's bad luck": perceptions of HIV as barriers to its prevention in Bata.

BACKGROUND: Currently, Africa is the region of the world where the highest number of new cases of HIV infection are registered. In 2022, Equatorial Guinea was the Central African country with the highest HIV prevalence (6.9%) and incidence (3.80 per 1,000 amongst the population of all ages). The main objective of this study was to determine the perceptions of HIV and the meanings given to it among the population of Equatorial Guinea in order to assess to what extent they represent a barrier to the prevention strategies implemented hitherto. METHODS: A total of 30 semi-structured interviews and nine focal groups were carried out. FINDINGS: The interviewees' testimonies revealed a combination of differing perceptions and meanings around HIV. In some cases, HIV was perceived as "a non-existent illness", and in others as "a disease of others", or as "a disease of bad luck". Other majority perceptions of HIV classed it as "a deadly disease" or "a sexual illness". CONCLUSIONS: All these perceptions of HIV and the social representations constructed around it can represent a barrier to adopting preventive practices. Hence, in order to improve efficacy, efficiency, and effectiveness, it is recommended that HIV prevention policies take into account the heterogeneity of meanings linked to the different social groups that have contracted the virus.

Accessible interferometric autocorrelator for noise-like pulses based on a Fabry-Perot cavity.

In this work, we develop experimentally a Fabry-Perot fiber optic interferometer applied to the measurement of autocorrelation of complex dynamic pulses generated by a figure-eight fiber laser. The principle is based in the superposition of multiple pulses, which requires two partially reflecting flat surfaces in parallel, resulting in a simple and compact autocorrelator design. The autocorrelation trace obtained exhibits a typical double-scaled structure for noise-like pulses (NLPs), with an ultrashort coherence spur on the order of 100 fs riding upon a broad pedestal of 120 ps. Finally, we show experimentally that the developed Fabry-Perot device is able to measure accurately the autocorrelation of NLPs, as confirmed by comparing the measurement with that of a conventional autocorrelator scheme based on a Michelson interferometer, with the additional advantages of a more compact setup and a much easier alignment procedure compared to the latter.

Graves' disease induced by Alemtuzumab in relapsing-remitting multiple sclerosis patients: an observational study in a reference center.

OBJECTIVES: Graves' disease induced by Alemtuzumab (GD-IA) is one of the most frequently observed adverse events in patients with multiple sclerosis (MS) treated with this drug. The aim of this study is the sequencing and description of these events, along with the identification of the risk factors leading to their development. MATERIALS AND METHODS: We conducted a retrospective observational study identifying patients with relapsing-remitting multiple sclerosis (RRMS) and GD-IA, studying their baseline clinical features and variables related to the natural history of the disease. RESULTS: A total of 121 participants treated with Alemtuzumab were included, of whom 41 developed GD-IA (33.9%). A higher percentage of first-degree relatives with autoimmune thyroid disease was documented in the subgroup who developed the abovementioned event (14.6% vs 1.5%; p < 0.01). A total of 70.7% of patients diagnosed with GD-IA (n = 29/41) had fluctuations in thyroid function during follow-up, and 24.4% (n = 10/41) required total thyroidectomy for resolution of the condition. In 54.8% of participants diagnosed with GD-IA, a pattern of significant TSH decline was identified in the month prior to diagnosis of the event, with high predictive ability and associated with a more favorable clinical course (fewer weeks to normalization of thyroid function, HR = 8.99; 95% CI [2.11-38.44]; p = 0.0003). CONCLUSION: GD-IA has an atypical course compared to classical forms of the disease. The identification of risk factors for the development of the disease before starting treatment with Alemtuzumab and early monitoring of thyroid function once this treatment is initiated prove to be useful strategies in the diagnosis and clinical management of this condition.

Specific versus non-specific exercises for the neck extensor muscles in women with chronic idiopathic neck pain: A randomized controlled trial.

BACKGROUND: Structural and functional impairments of the cervical extensor muscles have been demonstrated in people with neck pain. A global exercise approach targeting all neck extensor muscles has shown positive effects in this population. However, to date, the efficacy of exercises specifically targeting the deep neck extensors has neither been tested nor compared to global exercises for the neck extensors. OBJECTIVES: To compare the effects on pain and disability of a specific lower deep neck extensors (SLDNE) versus a general neck extensor (GNE) exercise program in women with chronic idiopathic neck pain. METHODS: Fourty-three women with chronic idiopathic neck pain were randomly allocated to either a six-week SLDNE or a GNE exercise program. As primary outcome, neck disability was measured with the Neck Disability Index (NDI). Secondarily, pain intensity (VAS), cervical ROM, pressure pain thresholds (PPTs), cervical and thoracic posture and self-perceived benefit of treatment (GROC) were also measured. Every outcome was measured at baseline and immediately after treatment, except NDI, which was also measured at 6-months follow-up. The GROC was only assessed post-intervention. RESULTS: Both exercise programs lead to reduced neck disability immediately post-intervention (within-group mean difference [MD] = -6.09; 95% Confidence Interval [CI]: 7.75, -4.42 and -4.73; 95%CI: 6.57, -2.91 respectively) and at the 6-months follow-up (-4.47; 95%CI: 6.41, -2.53 and -4.74; 95%CI: 6.50, -2.97), but with no between group differences. Similar results were found for pain intensity post-intervention, with no between group interaction (within-group MD = -20.87 mm; 95% CI: 28.55, -13.19 and -18.00 mm; 95%CI: (-26.24, -9.76) for SLDNE and GNE groups, respectively). GROC improved after both interventions without any between-group difference. CONCLUSIONS: A six-week exercise program specifically targeting the lower deep neck extensors lead to comparable outcomes as a general neck extensor exercise program in women with chronic idiopathic neck pain.

In situ measurements of reef squid polarization patterns using two-dimensional polarization data mapped onto three-dimensional tessellated surfaces.

Reef squids belong to a group reputed for polarization sensitivity, yet polarization patterns of reef squid have not been quantified in situ. To quantify polarization patterns from video polarimetric data, we developed a protocol to map two-dimensional polarization data onto squid-shaped three-dimensional tessellated surfaces. This protocol provided a robust data container used to investigate three-dimensional regions-of-interest, producing data lineouts derived from the squid's geometry. This protocol also extracted polarimeter and squid body orientations and the solar heading from polarization images. When averaged over the solar heading, the ventral midline gave a low degree of polarization (2.4 ± 5.3%), and the area between the ventral and flank midlines had higher values (9.0 ± 5.3%). These averaged data had a large discontinuity in the angle of polarization (AoP) at the mantle's ventral midline (64 ± 55°), with larger discontinuities measured on individual squid. Ray-tracing calculations demonstrated that the AoP pattern was not related to the squid's surface-normal geometry. However, the AoP followed virtual striation axes on the squid's surface oriented 24° to the squid's long axis, similar in angle (27°) to the striations of birefringent collagen fibres documented in other squid species' skin.

Surface-guided radiation therapy for breast cancer: more precise positioning

Introduction Hypofractionated radiation therapy for breast cancer requires highly precise delivery through the use of image-guided radiotherapy (IGRT). Surface-guided radiation therapy (SGRT) is being increasingly used for patient positioning in breast radiotherapy. We aimed to assess the role of SGRT for verification of breast radiotherapy and the tumour bed. Materials and method Prospective study of 252 patients with early stage breast cancer. A total of 1170 determinations of daily positioning were performed. Breast surface positioning was determined with SGRT (AlignRT) and correlated with the surgical clips in the tumour bed, verified by IGRT (ExacTrac). Results SGRT improved surface matching by a mean of 5.3 points compared to conventional skin markers (98.0 vs. 92.7), a statistically significant difference (p < 0.01, Wilcoxon Test). For surface matching values > 95%, ≥ 3 clips coincided in 99.7% of the determinations and all markers coincided in 92.5%. For surface matching rates > 90%, the location of ≥ 3 clips coincided in 99.55% of determinations. Conclusions SGRT improves patient positioning accuracy compared to skin markers. Optimal breast SGRT can accurately verify the localisation of the tumour bed, ensuring matching with ≥ 3 surgical clips. SGRT can eliminate unwanted radiation from IGRT verification systems (AU)

Dostarlimab for the treatment of endometrium cancer and other solid tumors.

The use of monoclonal antibodies directed against programmed cell death protein 1 (PD-1) and its ligand, programmed cell death 1 ligand 1 (PD-L1), widely extends to a large number of tumors such as melanoma, non-small cell lung, renal or lymphomas, among others. Some of them are already approved as first- or second-line treatment, as pembrolizumab, nivolumab or cemiplimab. Dostarlimab is an investigational humanized anti-PD-1 that is being developed both in monotherapy and as combination therapy, for gynecological tumors but also for lung cancer or melanoma. The preliminary results, particularly in endometrial cancer, show a high affinity against PD-1 with encouraging clinical activity. Here we summarize the development of this compound as well as the current preclinical and clinical data and potential future development.

Patterns of treatment failure in patients with prostate cancer treated with 76 80 radiotherapy to the prostate and seminal vesicles

Purpose To assess the pattern of treatment failure in patients with prostate cancer (PCa) treated with radiotherapy (76–80 Gy) ± hormone therapy (HT). We also evaluated the influence of treatment failure on survival outcomes. Methods Retrospective study of patients with PCa (n = 302) treated with radiotherapy (RT) ± HT at our centre between November 1999 and July 2007. The mean patient age was 70.2 years (range 51–87). Distribution by NCCN risk group was low (n = 80, 26.5%), intermediate (n = 86, 28.5%), high (n = 77, 25.5%), and very high (n = 49, 16.2%). Most patients (n = 273, 90.4%) received IMRT at a dose of 76–80 Gy. HT was administered in 237 patients (78.5%), in most cases (n = 167, 55.3%) for < 7 months Results Survival rates at 10 years were: overall survival (OS), 64.3%; biochemical disease-free survival, 83.9%; disease-free survival, 92.5%; and metastasis-free survival (MFS), 94.3%. Biochemical failure (BF) was observed in 55 cases (18.2%), 32 of whom subsequently developed clinical recurrence: metastasis (n = 17, 5.6%), local failure (n = 11, 3.6%), and regional failure (n = 4, 1.3%). The cause of death (n = 159) was intercurrent disease in 115 cases (72.3%), second cancer in 27 (17.0%), and PCa in 17 (10.7%). Biochemical failure-free survival ≤ 24 months was significantly associated with worse OS and MFS (p = 0.0001). Late genitourinary and gastrointestinal toxicity grade ≥ 3 (RTOG) was observed in 18 (6.0%) and 7 (2.3%) patients, respectively. Conclusions The main type of treatment failure after 76–80 Gy of radiotherapy ± HT is local or metastatic. In all cases, biochemical failure occurred prior to treatment failure. BF within 24 months of treatment completion was significantly associated with worse OS and MFS (AU)

Patterns of treatment failure in patients with prostate cancer treated with 76-80 Gy radiotherapy to the prostate and seminal vesicles ± hormonotherapy.

Differential biomarker profiles between unprovoked venous thromboembolism and cancer.

BACKGROUND: The relationship between cancer and venous thromboembolic disease (VTD) are complex because the activated coagulation factors are not only involved in thrombosis but also in malignant processes, such as angiogenesis and metastasis. OBJECTIVE: To compare phenotypes of extracellular vesicles (EVs), and levels of D-dimer, soluble P-selectin (sP-selectin) and antigenic tissue factor (TF) between unprovoked VTD patients, who did not develop cancer during one-year follow-up, and those with advanced stage of cancer but not associated with VTD. METHODS: A prospective study in which we included 138 unprovoked VTD patients and 67 advanced cancer patients, who did not develop thrombosis. Levels of EVs of different cellular origin (platelet, endothelium and leukocyte), EVs positive for tissue factor (TF) and P-selectin glycoprotein ligand 1 were quantified by flow cytometry. D-dimer, soluble P-selectin (sP-selectin) and antigenic TF were determined by ELISA. RESULTS: TF-positive EVs, D-dimer, and sP-selectin were markedly elevated in unprovoked VTD patients compared to cancer patients without association with thrombosis. CONCLUSIONS: Levels of TF-positive EVs, D-dimer and sP-selectin are able to discriminate between unprovoked VTD patients not related to cancer and cancer patients not associated with VTD. These results could lead to the application of EVs as biomarkers of both diseases. Key messages: Circulating EVs, specifically TF-positive EVs, in combination with plasmatic markers of hypercoagulable states, such as D-dimer, sP-selectin and antigen TF, are able to discriminate between cancer patients without thrombosis and patients with unprovoked VTD. Research fields could be opened. Future studies will assess if these biomarkers together serve as predicting thrombotic events in cancer populations.

Usefulness of autocidal gravid ovitraps for the surveillance and control of Aedes (Stegomyia) aegypti (Diptera: Culicidae) in eastern Colombia.

In the past decade, new strategies have been developed to control the Aedes aegypti (Diptera: Culicidae) mosquito vector, as well as a broad range of arboviral agents. Vector control surveillance programmes in Puerto Rico and Australia have implemented the Centers for Disease Control and Prevention autocidal gravid ovitrap (AGO), which has had an impact on vector density and, consequently, the epidemiology of arboviral infections. Colombia intends to establish the AGO as a new tool for the surveillance and control of the A. aegypti vector. AGOs were evaluated in a hyperendemic area for dengue virus during an 8-week period in Villavicencio city, eastern Colombia. The results indicated that the AGOs detect a high density of A. aegypti, with positive results for these traps of over 80% and an average catch of six individuals per trap per week. Acceptance of AGOs in the community exceeded 95%, and adherence was around 89%. This study's results demonstrate, for the first time in Colombia, that traps are a useful tool for the surveillance of A. aegypti. Future studies must consider the implementation of AGOs in the region.

Rotura del tendón distal del bíceps: potencia diagnóstica de la ecografía y la resonancia magnética / Distal biceps tendon rupture: diagnostic strength of ultrasonography and magnetic resonance

OBJETIVO: El objetivo fundamental de este estudio es determinar la concordancia entre dos pruebas radiológicas, la ecografía y la resonancia magnética, para el diagnóstico de rotura del tendón distal del bíceps braquial. MATERIAL Y MÉTODO: Se realizó un estudio retrospectivo de pacientes a lo largo de 3 años a los que se realizó cirugía abierta de reanclaje de tendón distal de bíceps y cuyo diagnóstico preoperatorio se complementó con ecografía, con resonancia magnética o bien con ambas. Se calculó la concordancia mediante el coeficiente kappa de Cohen (k). RESULTADOS: Se analizaron datos de 79 pacientes. La concordancia fue excelente entre resonancia y hallazgos quirúrgicos (k=0,950), y se obtuvo un índice de concordancia bueno tanto entre ecografía y cirugía (k=0,706) como entre ecografía y resonancia magnética (k=0,667). CONCLUSIONES: Tanto resonancia como ecografía se podrían considerar técnicas diagnósticas fiables para la determinación preoperatoria de rotura aguda del tendón distal del bíceps braquial en pacientes con mecanismo y clínica congruentes

OBJECTIVE: The main purpose of this study is to determine the agreement between two radiological tests, ultrasonography and magnetic resonance, in the diagnosis of distal brachial biceps tendon injury. MATERIAL AND METHOD: A retrospective study was made of patients over 3 years who underwent distal brachial biceps tendon reattachment open surgery, and whose preoperative diagnosis was complemented either by ultrasonography, by magnetic resonance or both. The agreement was calculated by Cohen's kappa coefficient (k). RESULTS: Information of 79 patients was analyzed. The concordance was excellent between resonance and surgical findings (k=.950), and a good Cohen's kappa coefficient was also achieved between both ultrasonography and surgery (k=.706) and between information of sonography and magnetic resonance (k=.667). CONCLUSIONS: Resonance and ultrasonography could be considered reliable diagnostic tests to determine the acute rupture of the distal brachial biceps tendon in patients with consistent aetiology and physical examination

Calidad de vida relacionada con la salud en pacientes oncológicos con enfermedad tromboembólica venosa aguda sintomática. Diseño del estudio qca (quality of life in cancer). Estudio de casos y controles / Health-related quality of life in cancer patients with acute symptomatic venous thromboembolic disease. Design of the QCa (quality of life in cancer) study. Case-control study

La asociación entre cáncer y enfermedad tromboembólica (ETV) se encuentra bien establecida. La ETV presenta una elevada morbimortalidad, objetivándose un incremento del riesgo de ETV hasta 4 veces mayor en aquellos pacientes con cáncer respecto a la población general. Sin embargo, existe poca evidencia científica sobre la CVRS (calidad de vida relacionada con la salud) en pacientes oncológicos con ETV, cuando es presumible que esta patología suponga un agravante sobre la percepción del estado de salud de los pacientes oncológicos. Nuestro objetivo es presentar el estudio "QCa Study", el cual pretende evaluar la CVRS de los pacientes oncológicos con ETV aguda sintomática en comparación con pacientes oncológicos sin ETV. "QCa study" es un estudio nacional de cohortes, prospectivo, de casos y controles en pacientes con cáncer activo. Definimos "caso" como aquel paciente oncológico con ETV aguda sintomática, y "control" aquel paciente oncológico sin ETV aguda sintomática. Los criterios de inclusión son: para los casos: presentar cáncer activo al momento de la inclusión. Tener más de 18 años, pacientes diagnosticados de trombosis venosa profunda (TVP) en miembros inferiores aguda sintomática o de embolia de pulmón (EP) confirmado de forma objetiva mediante pruebas de imagen y firma del consentimiento informado. Para los controles; presentar cáncer activo. Tener más de 18 años. Firma del consentimiento informado. Dado los escasos datos publicados respecto a la CVRS en pacientes con ETV, hemos diseñado el estudio Qca, para poder determinar el impacto que genera la ETV en la calidad de vida de los pacientes con cáncer

The association between cancer and venous thromboembolic disease (VTD) is well established. VTD presents a high rate of morbidity and mortality, with patients with cancer showing an increased risk of VTD that is up to 4 times greater than the general population. However, there is little scientific evidence on HRQoL (health-related quality of life) in cancer patients with VTD when this disease is likely to be an aggravating factor in perceived state of health among cancer patients. Our objective is to present the QCa study, which aims to evaluate the HRQoL of cancer patients with acute symptomatic VTD in comparison with cancer patients without VTD. The QCa study is a prospective, case-control national cohort study in patients with active cancer. We define "case" as a cancer patient with acute symptomatic VTD and "control" as a cancer patient without acute symptomatic VTD. Inclusion criteria for cases were: having active cancer at the time of inclusion, being over the age of 18, patients diagnosed with acute symptomatic deep vein thrombosis (DVT) in the lower extremities or pulmonary embolism (EP) that was objectively confirmed through imaging tests, and having signed the informed consent. For the controls: having active cancer, being over the age of 18, and having signed the informed consent. Given the scarce data published with regard to HRQoL in patients with VTD, we designed the QCa study to determine the impact VTD has on the quality of life of patients with cancer

Incidencia de enfermedad pulmonar obstructiva crónica en pacientes con el virus de la inmunodeficiencia humana. Análisis post-hoc del estudio viva / Incidence of chronic obstructive pulmonary disease in patients with human immunodeficiency virus. Post-hoc analysis of the viva study

Introducción: desde la aparición de la terapia antiretroviral la supervivencia de los pacientes infectados por el virus de la inmunodeficiencia humana (VIH) ha aumentado considerablemente tomando importancia la aparición de otras patologías crónicas en estos pacientes como puede ser la enfermedad pulmonar obstructiva crónica (EPOC). Nuestro objetivo fue conocer la incidencia de EPOC en una cohorte de pacientes VIH derivados en un programa de detección de hipertensión pulmonar (HTP). Material y Métodos: análisis post-hoc, de un prospectivo, pseudo-experimental de pacientes con infección del VIH a los que se les preguntaba por disnea y en caso afirmativo eran derivados a consultas de neumología para despistaje de HTP. Resultado: desde 2014 hasta 2016, reclutamos un total de 32 pacientes, con un predominio de varones (75%). La disnea según la mMRC (Medical Reserach Council) fue grado 1, 2 y 3 en el 37,5%, 43,8% y 18,8%, respectivamente. La prevalencia de tabaquismo fue del 87,1% (intervalo de confianza [IC] 95%: 71- 96,4%), y 18 pacientes fueron catalogados de EPOC (62%; IC95%: 42,2 - 79,3%). Conclusión: la incidencia de EPOC en nuestra serie fue muy superior a la de la población general. Es necesario plantear estrategias de búsqueda activa de EPOC en estos pacientes para un diagnóstico y tratamiento precoz

Introduction: Since the advent of antiretroviral therapy, the survival of patients infected with the human immunodeficiency virus (HIV) has considerably increased, with the occurrence of other chronic diseases such as chronic obstructive pulmonary disease (COPD) gaining importance in these patients. Our objective was to find out the incidence of COPD in a cohort of HIV patients that were referred to a program to detect pulmonary hypertension (PH). Materials and Methods: Post hoc analysis of a prospective, quasi-experimental study on HIV-infected patients who were asked whether they had dyspnea. If this was the case, they were referred to a pulmonologist for PH screening. Results: From 2014 to 2016, we recruited a total of 32 patients, with a predominance of male recruits (75%). According to the mMRC (Modified Medical Research Council) Dyspnea Scale, 37.5%, 43.8% and 18.8% were classified as Grade 1, 2 and 3, respectively. The prevalence of smoking was 87.1% (95% confidence interval [CI]: 71 - 96.4%), and 18 patients were classified with COPD (62%; 95% CI: 42.2 - 79.3%). Conclusion: The incidence of COPD in our sample was much higher than that of the general population. It is necessary to plan active search strategies for COPD in these patients for early diagnosis and treatment
