Charting a path to health: The empowering influence of self-efficacy for the self-management of type 1 diabetes in children and adolescents.

Type 1 diabetes (T1D) in children and adolescents requires a lifelong commitment to disease control, which involves insulin treatment and constant blood glucose monitoring. Framed by Albert Bandura's self-efficacy theory, we focused on analysing the impact of domain-specific self-efficacy for T1D control in children and adolescents and its relationship with different indicators of glycaemic control over time. The study included 205 participants (56.1% male), including 51.7% children and 48.3% adolescents aged 6-18 (M = 13.27, SD = 3.66) years in four longitudinal phases (6 months between phases). The results revealed that higher self-efficacy predicted better health outcomes, with more time spent actively monitoring glucose and more time in the target range. The positive effect of self-efficacy was observed to be maintained over time. This study underscores the importance of taking into account the developmental timing in the onset of T1D. There was a significant relationship between self-efficacy and glucose indicators in adolescents. Although their glucose indicators were worse, self-efficacy became more relevant as they moved from parental management to the self-management of T1D. Implications of the results show the positive effect of self-efficacy on health per glucose indicators, thus suggesting interventions that promote self-efficacy in this population.

Functional and radiological outcomes of total knee arthroplasty using posterior-stabilized U2 knee system: A retrospective study in 560 cases at five years of follow-up.

PURPOSE: The purpose of this study was to assess clinical and functional outcomes as well as the prosthesis survival rates of the U2 Knee system in primary total knee arthroplasty (TKA) with a minimum follow-up of four years. METHODS: We retrospectively analyzed 560 consecutively primary TKA performed between 2015 and 2019 due to osteoarthritis with a mean follow-up of 5.4 ± 1.1 years. The clinical outcomes were assessed using the knee society score (KSS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Radiographic outcomes were assessed using the American knee society's roentgenographic evaluation system. Prosthetic survival was calculated using the Kaplan-Meier method. RESULTS: Postoperative KSS showed significant improvement at one year (Clinical: 37.4 ± 4.1 vs. 91.9 ± 3.7; p < 0.01; Functional: 41.2 ± 3.3 vs. 90.6 ± 4.8; p = < 0.01), with these improvements maintained throughout the follow-up period. The WOMAC score improved from 60 ± 10.1 preoperatively to 10.9 ± 8.3 (p = 0.02) at the end of the follow-up. There were 20 (3.7%) knees with radiolucent lines around the implant (< 2 mm), and none showed evidence of loosening. There were six (1.1%) revisions-four due to prosthetic joint infections and two due to periprosthetic femur fracture. The prosthetic survival was 97.8% at the study closure. CONCLUSION: The U2 knee system demonstrates effective and safe performance for primary TKA with significant improvements in functional scores, patient-reported outcomes, and a promising prosthesis survival rate at mid-term follow-up. We will continue with the series analysis to assess the long-term outcomes.

Distal articular involvement in tibial shaft fractures: an evaluation of 125 consecutive cases.

PURPOSE: To report the incidence and morphology of ipsilateral distal articular involvement (DAI) in a consecutive series of tibial shaft fractures. METHOD: A retrospective review was performed on 115 patients who underwent intramedullary nailing for tibia shaft fractures. Ankle evaluations included preoperative radiographs and computed tomography (CT) scans in all patients. RESULTS: Thirty-two patients (27.8%) in our series presented with tibial shaft fractures associated with DAI. Tibial spiral fractures (42A1) were significantly related to DAI (RR: 1788). In 28 (87.5%; 28/32) articular fractures, posterior malleolus fractures (PMF) were present; 22 were isolated, and six (18.8%) occurred in combination with medial malleolus or anterolateral fractures. The remaining (12.5%; 4/32) were isolated medial malleolus fractures. Ten (31.2%; 10/32) articular fractures were occult on the radiographs and only detected on CT scan. CONCLUSION: DAI is common in tibial shaft fractures. CT evaluation is mandatory due to the high number of occult fractures. Although isolated PMF is the most frequent pattern of DAI involvement, 31.3% of the cases exhibited different patterns.

Does the distal nail position impact the rates of misalignment and bone union in distal tibial fractures?

PURPOSE: This retrospective study aimed to assess the impact of distal nail placement on misalignment and healing rates in distal tibial fractures. METHODS: We reviewed all patients with distal tibial fracture treated with intramedullary nailing between 2015 and 2021, and a minimum follow-up of 12 months. Distal nail positioning was determined according to the Triantafillou zones. We related these positioning zones to misalignments (alignment ≥ 3°) and too bony union disorders (delayed union, non-union). RESULTS: Out of the 62 patients included, 56 (90.3%) show bone union without additional procedure, 3 (4.8%) with dynamization, and 3 (4.8%) showed non-union. Twenty-one (33.8%) presented misalignment, with valgus in the coronal plane being the most frequent (76.19%). In patients with and without misalignment, the most frequent distal nail position was 2-2 in 47.6% and 80.5%, respectively (p = 0.01). In multivariate analysis, distal nail positioning in the 2-2 zone showed a significant protective effect against misalignment (OR 0.18; p = 0.018), while nail positioning in the 3-2 zone generated a significant risk of misalignment (OR 18.55; p = 0.009). CONCLUSION: In intramedullary nailing of distal tibial fractures, distal positioning of the nail slightly lateral to the center of the talus in the coronal plane and slightly posterior in the sagittal plane (zone 2-2) allows high alignment percentages to be obtained. Positioning medial to this point in the coronal plane (zone 3) is associated with more significant misalignment and should be avoided.

Diagnostic evaluation and incorporation of PSA density and the prostate imaging and data reporting system (PIRADS) version 2 classification in risk-nomograms for prostate cancer.

PURPOSE: The diagnostic approach for prostate cancer still depends on PSA and DRE. OBJECTIVES: to evaluate the diagnostic validity of PSA-Density and PIRADSv2 as diagnostic tests regarding biopsy results, and to design nomograms that include all diagnostic variables for malignancy, significant tumor (ST) and high-grade tumor. METHODS: Cross-sectional study which included men with PSA ≥ 4 ng/ml and/or suspicious DRE, PIRADSv2 ≥ 3 lesions on multiparametric MRI and prostate biopsy. The gold standard test was the maximum ISUP of the targeted biopsy per patient (malignancy: ISUP ≥ 1, ST: ISUP ≥ 2, high-grade tumor: ISUP ≥ 4). Association and logistic regression tests were used and diagnostic validity parameters using PSA-Density and PIRADSv2 classification was analyzed. Nomograms were designed for malignancy, ST, and high-grade tumor using the best model selection procedure from all possible equations. RESULTS: 336 men with median age, PSA and PSA-Density of 67.7 years (IQR:12.6), 6.3 ng/ml (IQR:3.3) and 0.12 ng/ml/cc (IQR:0.10), respectively; 63 index lesions were PIRADS3, 204 PIRADS4, and 69 PIRADS5. 65.8% and 37.8% were malignant and ST, respectively. The significant positive association highlighted between malignancy and ST with age, DRE, PSA-Density and PIRADSv2. PSA-Density and PIRADSv2 ≥ 3 presented the highest sensitivity to detect malignancy, and their combination showed sensitivity nearly 95% (AUC:0.803). Nomograms for malignancy and ST included the variables age, DRE, PSA-Density, and PIRADSv2 with a sensitivity closely 91% (AUC:0.833), and a specificity of almost 85% for ST, exposing risk < 5% for ST when PSA-Density is < 0.15, not suspicious DRE and PIRADS3. CONCLUSION: PSA-Density and PIRADSv2 classification in risk nomograms can provide highly relevant information to increase the accuracy in the diagnosis of PC and ST.

Reverse TAR may be added when necessary in open preperitoneal repair of lateral incisional hernias: a retrospective multicentric cohort study.

BACKGROUND: The best approach for lateral incisional hernia is not known. Posterior component separation (reverse TAR) offers the possibility of using the retromuscular space for medial extension of the challenging preperitoneal plane. The aim of our multicenter study was to compare the operative and patient-reported outcomes measures (PROMs) using two open surgical techniques from the lateral approach: a totally preperitoneal vs a reverse TAR. METHODS: A retrospective cohort study was performed since 2012 to 2020. Patients with lateral incisional hernia treated through a lateral approach were identified from a prospectively maintained multicenter database. Reverse TAR was added when the preperitoneal plane could not be safely dissected. The results obtained using these two lateral approaches were compared, including short- and long-term complications, as well as PROMs, using the specific tool EuraHSQoL. RESULTS: A total of 61 patients were identified. Reverse TAR was performed in 33 patients and lateral retromuscular preperitoneal approach in 28 patients. Both groups were comparable in terms of sociodemographic and comorbidities variables. Surgical site occurrences occurred in 13 cases (21.3%), with 8 patients (13.1%) requiring procedural intervention. During a median follow-up of 34 months, no incisional hernia recurrence was registered. There was a case (1.6%) of symptomatic bulging that required reoperation. Also 12 patients (19.7%) presented an asymptomatic bulging. No statistically significant difference was identified in the complications and PROMs between the two procedures. CONCLUSION: The open lateral retromuscular reconstruction using very large meshes that reach the midline has excellent long-term results with acceptable postoperative complications, including PROMs. A reverse TAR may be added, when necessary, without increasing complications and obtaining similar long-term results.

Factors Associated with Quality of Life in Relatives of Adults with Serious Mental Illness: A Systematic Review.

Caring for a family member with a serious mental illness often has an impact on the quality of life (QoL) of caregivers. This could have negative repercussions on their caring skills and thus affect the care provided to that individual. The aim of this paper is to identify current evidence on QoL factors affecting relatives of individuals suffering from serious mental illness. A systematic review related to the research question was conducted in six databases by two independent reviewers. The QoL factors of relatives include sociodemographic, contextual, psychological, physical, and patient factors. The findings are consistent with the results of previous research. Mental health professionals may support a family with a member diagnosed with a serious mental illness by enhancing their education about QoL factors, which would trigger and promote protective factors so that family members could assess and act on them on an ongoing basis.

Endothelial Dysfunction: An Intermediate Clinical Feature between Urolithiasis and Cardiovascular Diseases.

An epidemiological relationship between urolithiasis and cardiovascular diseases has extensively been reported. Endothelial dysfunction is an early pathogenic event in cardiovascular diseases and has been associated with oxidative stress and low chronic inflammation in hypertension, coronary heart disease, stroke or the vascular complications of diabetes and obesity. The aim of this study is to summarize the current knowledge about the pathogenic mechanisms of urolithiasis in relation to the development of endothelial dysfunction and cardiovascular morbidities. METHODS: A non-systematic review has been performed mixing the terms "urolithiasis", "kidney stone" or "nephrolithiasis" with "cardiovascular disease", "myocardial infarction", "stroke", or "endothelial dysfunction". RESULTS: Patients with nephrolithiasis develop a higher incidence of cardiovascular disease with a relative risk estimated between 1.20 and 1.24 and also develop a higher vascular disease risk scores. Analyses of subgroups have rendered inconclusive results regarding gender or age. Endothelial dysfunction has also been strongly associated with urolithiasis in clinical studies, although no systemic serum markers of endothelial dysfunction, inflammation or oxidative stress could be clearly related. Analysis of urine composition of lithiasic patients also detected a higher expression of proteins related to cardiovascular disease. Experimental models of hyperoxaluria have also found elevation of serum endothelial dysfunction markers. CONCLUSIONS: Endothelial dysfunction has been strongly associated with urolithiasis and based on the experimental evidence, should be considered as an intermediate and changeable feature between urolithiasis and cardiovascular diseases. Oxidative stress, a key pathogenic factor in the development of endothelial dysfunction has been also pointed out as an important factor of lithogenesis. Special attention must be paid to cardiovascular morbidities associated with urolithiasis in order to take advantage of pleiotropic effects of statins, angiotensin receptor blockers and allopurinol.

Effect of support groups on caregiver's quality of life.

The objective of this study was to evaluate the effect that participating in support groups for caregivers has on the quality of life and psychotropic drug use of family caregivers of adults with limitations in activities of daily living. A controlled quasi-experimental longitudinal design was used with 134 caregivers (64 in the experimental group and 70 in the control group). The outcomes were health-related quality of life (EuroQol 5D3L test) and psychotropic drug use (no/yes). The analyses were performed using SPSS and R statistical software. An interaction was observed between the condition and the level of limitations in activities of daily living of the care receiver, having an effect on the caregiver's psychotropic drug use (p = 0.003), with this use being lower among caregivers who attend support groups when their relatives present fewer limitations in activities of daily living. Moreover, the quality of life was higher in the post-test in the experimental group (B = 8.66, p = 0.015). In conclusion, support groups could improve the caregiver's quality of life and decrease psychotropic drug use when the care receiver has low limitations in activities of daily living.

El objetivo de este estudio es evaluar el efecto que tiene la participación en grupos de apoyo para cuidadores en la calidad de vida y el consumo de fármacos psicotrópicos de cuidadores familiares de adultos con limitaciones en las actividades de la vida diaria. Se usó un diseño longitudinal cuasiexperimental controlado con 134 cuidadores (64 en el grupo experimental y 70 en el grupo de referencia). Los criterios de evaluación fueron la calidad de vida relacionada con la salud (test EuroQol 5D3L) y el consumo de fármacos psicotrópicos (sí / no). Los análisis se realizaron usando los programas estadísticos SPSS y R. Se observó una interacción entre la enfermedad y el nivel de limitaciones en las actividades de la vida diaria del receptor del cuidado y el efecto que tuvo en el consumo de fármacos psicotrópicos del cuidador (p=0.003). Este consumo fue menor entre los cuidadores que asisten a grupos de apoyo cuando sus familiares presentan menos limitaciones en las actividades de la vida diaria. Además, la calidad de vida fue mayor en el grupo experimental después del test (B=8.66, p=0.015). En resumen, los grupos de apoyo podrían mejorar la calidad de vida del cuidador y disminuir el consumo de fármacos psicotrópicos cuando el receptor del cuidado tiene pocas limitaciones en las actividades de la vida diaria.

High recurrence rate after posterior component separation and keyhole mesh reconstruction for complex parastomal hernia: A case series study.

AIM: This study aimed to describe the results of complex parastomal hernia repair after posterior component separation and keyhole reconstruction. METHOD: We conducted a retrospective review of a prospectively sustained database in one single complex abdominal wall referral centre. We analysed the data of patients who underwent the posterior component separation technique using modified transversus abdominis release for complex parastomal hernia and retromuscular keyhole mesh repair from February 2014 to January 2017. Demographic data, hernia characteristics, operative details and outcomes were analysed. The primary outcome measured was the recurrence rate during the follow-up. RESULTS: Twenty patients were included in this study. Among the patients who underwent surgery for parastomal hernia, 17 patients had a colostomy (85%) and three patients had a ureteroileostomy after the Bricker procedure (15%). The mean body mass index was 33.2 kg/m2 (range 25-47). Twelve patients had an expected associated risk according to the Carolinas equation for determining associated risk classification of >60%. Sixty per cent of our patients had contaminated or dirty/infected wounds. The overall complication rate was 60%. Surgical site infection was observed in 25% of the cases. The mortality rate in our study group was 5% (n = 1). We found clinical or radiological evidence of parastomal hernia recurrence in nine out of 20 (45%) patients during follow-up. No hernia recurrence was detected in the concomitant incisional hernias. CONCLUSIONS: Although posterior component separation in the form of modified transversus abdominis muscle release allows abdominal wall reconstruction, keyhole mesh configuration at the stoma site does not offer satisfactory results in terms of long-term recurrence rate at the parastomal defect.

A Novel Penile Splint as Early Traction Therapy After Grafting Techniques for Peyronie's Disease.

BACKGROUND: Some studies showed encouraging results on the efficacy and safety of penile traction therapy after Peyronie's disease (PD) surgery. The early traction therapy (ETT) could be an effective and safe approach to minimize penile shortening in patients undergoing PD surgery. AIM: To evaluate the feasibility, efficacy, and safety of a novel penile splint as ETT in patients with PD undergoing grafting techniques. METHODS: Patients with PD underwent plaque incision and grafting technique; at the end of the procedure, a novel penile splint (ETT) was applied to all patient. The device consisted of 2 10CH intubating stylets, self-adapted to each patient, that kept the penis stretched with the aid of non-absorbable sutures. The total expense for the materials needed to build each penile splint was less than 15 euros. This active traction was maintained for 1-3 weeks; then, we removed the stitches leaving the device on-site for a passive traction. Within 3-4 weeks from surgery, the penile splint was replaced by a standard penile traction device. OUTCOMES: The main outcomes evaluated at 6 months included stretched penile length (SPL), penile curvature, International Index of Erectile Function-erectile function (IIEF-EF) domain, patient satisfaction, and time to first satisfactory sexual intercourse. RESULTS: A total of 46 patients were enrolled. The median preoperative IIEF-EF, penile curvature, and SPL were 27 points, 70°, and 13 cm, respectively. The median follow-up was 15 months. The median postoperative IIEF-EF was 25 points (P < .001). The median residual penile curvature was 10° (P < .001). The median postoperative SPL was 13 cm (P = .269). 8 patients (17.4%) lost 1 cm of SPL; no shortening greater than 1 cm was recorded. The median time to first satisfactory sexual intercourse and patient satisfaction score was 6 weeks and 9 points, respectively. CLINICAL IMPLICATIONS: Our results could pave the way for a new line of research, which in turn could lead to an improvement in the postoperative management of the patient undergoing surgery for PD. STRENGTH & LIMITATIONS: This is the first study evaluating the ETT after PD surgery. The main limitation of this study is the lack of a randomized control group. Other weaknesses are the small sample size and the short follow-up time. CONCLUSION: Our novel penile splint is inexpensive, easy to assemble, and adaptable to the patient. ETT using this novel device, followed by standard traction therapy, seems to be feasible, effective, and safe. Fernández-Pascual E, Manfredi C, Cocci A, et al.

Multicenter Prospective Study of Grafting With Collagen Fleece TachoSil in Patients With Peyronie's Disease.

BACKGROUND: A xenograft consisting of equine collagen coated with human fibrinogen and thrombin (TachoSil; Baxter, CA) has recently been introduced in grafting procedures for Peyronie's disease (PD). AIM: To describe the results of a multicenter prospective registry on patients with PD undergoing plaque incision or and grafting (PIG) or plaque excision and grafting (PEG) with collagen fleece TachoSil, to evaluate the efficacy and safety of this procedure. METHODS: A prospective non-controlled multicenter study of patients with PD was performed between May 2016 and March 2018. Patients from 10 centers with stable PD for at least 3 months, difficulties in sexual intercourse, normal erectile function with or without pharmacological treatment, curvature >45°, and/or penile shortening and/or complex deformities were included. All patients underwent PIG/PEG with collagen fleece TachoSil. OUTCOMES: The main outcome measure of this study were penile curvature correction (intraoperative), penile shortening (intraoperative), erectile function with the 5-item version of the International Index of Erectile Function (IIEF-5) and the Erection Hardness Score, subjective patient outcomes with non-validated questionnaires, and complications. RESULTS: A total of 52 patients were enrolled in the study. The mean (SD) preoperative penile curvature was 72.8° (17.0). PIG was the preferred technique (80.8%). Intraoperatively, complete curvature correction was achieved in 92.3%, and no significant penile shortening was recorded in 80.8% of subjects. Subjective penile shortening was reported in 83.3% of patients at 6 months. No objective measurement of penile curvature and length was recorded during follow-up. No statistically significant difference from the baseline was found in IIEF-5 and Erection Hardness Score at 3 or at 6 months, although 16.7% of men experienced a worsening of IIEF-5 scores and 14.3% required de novo phosphodiesterase type 5 inhibitor use. 6 months after surgery, 78.5% of men were satisfied with intervention. Swelling and ecchymosis/hematoma were the most common perioperative complications (40.4%). 2 cases (3.8%) of wound infection were recorded. At 6 months, 35.7% of patients reported mild penile hypesthesia. CLINICAL IMPLICATIONS: Our results confirm the high success rate of grafting with TachoSil, and the surgeon perceived low percentage of penile shortening. STRENGTH & LIMITATIONS: This is the first multicentre study on patients with PD undergoing grafting with TachoSil without concomitant placement of penile prosthesis. The main limitations are the short follow-up and the relatively small sample size. CONCLUSION: Grafting with TachoSil after PIG/PEG in patients with PD is an effective and safe procedure. Among the main advantages of this technique, there are ease of use of the graft and reduced operative time. Fernández-Pascual E, Manfredi C, Torremadé J, et al.

Health-related quality of life in women with polycystic ovary syndrome attending to a tertiary hospital in Southeastern Spain: a case-control study.

BACKGROUND: Polycystic ovary syndrome (PCOS) is a chronic condition with symptoms affecting many women at reproductive age and evaluating their health-related quality of Life (HRQoL) is an important issue. Moreover, differences in the HRQoL between women with different PCOS phenotypes have never been analyzed. Therefore, the aim of our study was to compare the HRQoL between women with PCOS -and its phenotypes- and controls attending to a tertiary hospital. METHODS: A group of 117 women with PCOS and 153 controls were studied between 2014 and 2016. Controls were women without PCOS attending the gynecological outpatient clinic for routine examinations. Cases were women attending the same setting and diagnosed with PCOS. PCOS diagnose was performed following the Rotterdam Criteria and women were further classified by anovulatory or ovulatory phenotypic subtype. Women underwent physical and gynecological exams and completed health questionnaires including the Short Form-12v2. Eight scales and two component summary scores [Physical (PCS) and Mental (MCS), respectively] were calculated. Bivariate and multivariate analyses were performed to assess differences in HRQoL between women with PCOS and controls. RESULTS: All women with PCOS and anovulatory PCOS presented lower score in PCS compared to controls [mean (95%CI): 53.7 (52.5-54.9) and 52.9 (51.5-54.4) vs. 55.8 (54.8-56.8); p-values< 0.01], as well as lower scores for five out of the eight scales (p-values < 0.05) after adjusting by age, body mass index, infertility, educational level and current occupation. No significant differences were observed for the MCS between women with or without PCOS or its phenotypic subtypes. CONCLUSIONS: HRQoL was significantly decreased in adult women with PCOS and its anovulatory phenotype compared to controls attending the outpatient clinic of a tertiary hospital. These results may have implications for the clinical practice and suggest the need for specific interventions in women with PCOS.

How do the new Olympic sports compare with the traditional Olympic sports? Injury and illness at the 2018 Youth Olympic Summer Games in Buenos Aires, Argentina.

OBJECTIVE: To describe injuries and illnesses across traditional and new sports among the participating athletes of the Buenos Aires 2018 Youth Olympic Summer Games (BA YOG) (6-18 October 2018). METHODS: We recorded the daily number of athlete injuries and illnesses (1) through the reporting of all National Olympic Committee (NOC) medical teams and (2) in the polyclinic and medical venues manned by the BA YOG 2018 medical staff. RESULTS: In total, 3.984 athletes from 206 NOCs were observed. NOCs and BA YOG 2018 medical staff reported 619 injuries and 334 illnesses, equalling 15.5 injuries and 8.4 illnesses per 100 athletes over the 13-day period. The eight new sports on the Youth Olympic programme (futsal, beach handball, karate, roller speed skating, kitesurfing, BMX freestyle, climbing and break dancing) fell in between the other sports with respect to injury and illness risk. Injury incidence was highest in rugby (43% of all rugby players), followed by boxing (33%) and badminton (24%), and lowest in swimming, archery, roller speed skating, equestrian, climbing and rowing (<5%). The highest incidences of illness were recorded in golf (20%), followed by triathlon (16%), beach volleyball and diving (both 14%). Of the illnesses, 50% affected the respiratory system and 15% the gastrointestinal system. Injury and illness incidences varied between continents with athletes representing Europe having significantly fewer injuries and illnesses compared with other continents, apart from a similar illness incidence to Asian athletes. CONCLUSION: The overall injury incidence of 15.5 injuries per 100 athletes was higher, while the overall illness incidence of 8.4 illnesses per 100 athletes was similar to previous youth and Olympic Games. The new sports did not differ significantly compared with the other sports with respect to injury and illness risk.

A Web-Based, Computer-Tailored Intervention to Reduce Alcohol Consumption and Binge Drinking Among Spanish Adolescents: Cluster Randomized Controlled Trial.

BACKGROUND: Alcohol consumption, including binge drinking (BD) and heavy episodic drinking (HED), is one of the leading risk factors among Spanish adolescents leading to significant social, health, and economic consequences. Reduction of BD and HED in adolescents can be achieved using Web-based, computer-tailored (CT) interventions, providing highly personalized feedback that is adapted to a person's individual characteristics and needs. Randomized controlled trials assessing the effects of tailored BD reduction programs among Spanish adolescents are scarce. OBJECTIVE: The aim of this study was to test the effectiveness of the Web-based, CT intervention Alerta Alcohol, aimed at the prevention of BD in Spanish adolescents. As a secondary outcome, effects on HED, weekly consumption, and any consumption were also assessed. The adherence and process evaluation were assessed. METHODS: A cluster randomized controlled trial conducted among 15 Spanish schools was developed. Each school was randomized into either an experimental condition (EC) (N=742) or a control condition (CC) (N=505). Finally, 351 participants for the EC and 261 for the CC were included in the analysis (N=612). Baseline assessment took place in January and February 2017. Demographic variables and alcohol use were assessed at baseline. Follow-up assessment of alcohol use took place 4 months later in May and June 2017. Participants were compared according to their randomization group (EC versus CC). After the baseline assessment, participants in the EC started the intervention, which consisted of short stories about BD, in which CT feedback was based on the I-Change Model for behavior change. Participants in the CC group only received the baseline questionnaire. Effects of the intervention were assessed using a three-level mixed logistic regression analysis for BD, HED, and any consumption, and a three-level mixed linear regression analysis for weekly consumption. RESULTS: In total, 1247 adolescents participated in the baseline assessment and 612 participated in the follow-up assessment; the attrition rate was 50.92%. The intervention was effective in reducing HED among adolescents; the odds of HED in the CC was nine times that in the experimental condition (P=.04). No effects were found for BD, weekly consumption, and any consumption. Process evaluations revealed that the adolescents were satisfied with the program (68.8%), would use the program again (52.9%), and would recommend it to someone else (62.8%). Females and non-binge drinkers showed better responses in the process evaluation. CONCLUSIONS: Our intervention was effective regarding HED but not regarding BD, weekly consumption, and any consumption. It may be that limiting alcohol consumption to prevent HED was easier in the Spanish context than it was to carry out further steps, such as reducing other patterns of alcohol consumption. Hence, additional actions are needed to accomplish these latter goals, including community approaches and policy actions aimed at denormalizing alcohol consumption among Spanish adolescents. TRIAL REGISTRATION: ClinicalTrials.gov NCT03288896; https://clinicaltrials.gov/ct2/show/NCT03288896. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): RR2-10.1186/s12889-018-5346-4.

Impact of 68Ga-PSMA PET/CT in the treatment of prostate cancer: Initial experience in Spain.

AIM: To evaluate whether positron-emission tomography/computed tomography with 68Ga-PSMA (68Ga-PSMA PET/CT) influences the therapeutic management of patients with primary or recurrent prostate cancer (PCa). BACKGROUND: Although 68Ga-PSMA PET/CT is one of the best options for staging or restaging patients with PCa, its availability is still very limited in Spain. The present study reports the results of the first group of patients in Spain who underwent 68Ga-PSMA PET/CT imaging. MATERIALS AND METHODS: All patients (n = 27) with a histological diagnosis of PCa who underwent 68Ga-PSMA PET/CT prior to the definitive treatment decision at the only centre with this technology in Spain during 2017-2018 were included. Two nuclear medicine physicians and a radiologist reviewed the imaging studies. The clinical impact was assessed from a theoretical perspective, based on the treatment that would have been applied if no data from the 68Ga-PSMA PET/CT were available. RESULTS: Most patients (n = 26; 96%) had persistent disease or biochemical recurrence after radical prostatectomy, radiotherapy, or combined treatment. One patient underwent 68Ga-PSMA PET/CT imaging to stage high-risk PCa. Overall, 68Ga-PSMA PET/CT was positive in 19 patients (70.4%). In 68.75% of these patients, none of the other imaging tests-MRI, CT, or bone scans-performed prior to the 68Ga-PSMA PET/CT were able to detect the presence of cancerous lesions. Overall, the findings of the 68Ga-PSMA PET/CT led to a modification of the therapeutic approach in 62.96% of the patients in the study. CONCLUSIONS: 68Ga-PSMA PET/CT alters the therapeutic approach in a substantial proportion of patients with PCa.

The Novel N,N-bis-2-Hydroxyethyl-2-Aminoethanesulfonic Acid-Gluconate-Polyethylene Glycol-Hypothermic Machine Perfusion Solution Improves Static Cold Storage and Reduces Ischemia/Reperfusion Injury in Rat Liver Transplant.

Organ transplantation is the treatment of choice against terminal and irreversible organ failure. Optimal preservation of the graft is crucial to counteract cold ischemia effects. As we developed an N,N-bis-2-hydroxyethyl-2-aminoethanesulfonic acid-gluconate-polyethylene glycol (BGP)-based solution (hypothermic machine perfusion [HMP]), we aimed to analyze the use of this solution on static cold storage (SCS) of rat livers for transplantation as compared with the histidine tryptophan ketoglutarate (HTK) preservation solution. Livers procured from adult male Sprague Dawley rats were preserved with BGP-HMP or HTK solutions. Liver total water content and metabolites were measured during the SCS at 0°C for 24 hours. The function and viability of the preserved rat livers were first assessed ex vivo after rewarming (90 minutes at 37°C) and in vivo using the experimental model of reduced-size heterotopic liver transplantation. After SCS, the water and glycogen content in both groups remained unchanged as well as the tissue glutathione concentration. In the ex vivo studies, livers preserved with the BGP-HMP solution were hemodynamically more efficient and the O2 consumption rate was higher than in livers from the HTK group. Bile production and glycogen content after 90 minutes of normothermic reperfusion was diminished in both groups compared with the control group. Cellular integrity of the BGP-HMP group was better, and the histological damage was reversible. In the in vivo model, HTK-preserved livers showed a greater degree of histological injury and higher apoptosis compared with the BGP-HMP group. In conclusion, our results suggest a better role of the BGP-HMP solution compared with HTK in preventing ischemia/reperfusion injury in the rat liver model.

Organ Preservation into the 2020s: The Era of Dynamic Intervention.

Organ preservation has been of major importance ever since transplantation developed into a global clinical activity. The relatively simple procedures were developed on a basic comprehension of low-temperature biology as related to organs outside the body. In the past decade, there has been a significant increase in knowledge of the sequelae of effects in preserved organs, and how dynamic intervention by perfusion can be used to mitigate injury and improve the quality of the donated organs. The present review focuses on (1) new information about the cell and molecular events impacting on ischemia/reperfusion injury during organ preservation, (2) strategies which use varied compositions and additives in organ preservation solutions to deal with these, (3) clear definitions of the developing protocols for dynamic organ perfusion preservation, (4) information on how the choice of perfusion solutions can impact on desired attributes of dynamic organ perfusion, and (5) summary and future horizons.

Machine Learning Techniques to Identify Antimicrobial Resistance in the Intensive Care Unit.

The presence of bacteria with resistance to specific antibiotics is one of the greatest threats to the global health system. According to the World Health Organization, antimicrobial resistance has already reached alarming levels in many parts of the world, involving a social and economic burden for the patient, for the system, and for society in general. Because of the critical health status of patients in the intensive care unit (ICU), time is critical to identify bacteria and their resistance to antibiotics. Since common antibiotics resistance tests require between 24 and 48 h after the culture is collected, we propose to apply machine learning (ML) techniques to determine whether a bacterium will be resistant to different families of antimicrobials. For this purpose, clinical and demographic features from the patient, as well as data from cultures and antibiograms are considered. From a population point of view, we also show graphically the relationship between different bacteria and families of antimicrobials by performing correspondence analysis. Results of the ML techniques evidence non-linear relationships helping to identify antimicrobial resistance at the ICU, with performance dependent on the family of antimicrobials. A change in the trend of antimicrobial resistance is also evidenced.

Prevention of Ventilator-Associated Pneumonia: The Multimodal Approach of the Spanish ICU "Pneumonia Zero" Program.

OBJECTIVES: The "Pneumonia Zero" project is a nationwide multimodal intervention based on the simultaneous implementation of a comprehensive evidence-based bundle measures to prevent ventilator-associated pneumonia in critically ill patients admitted to the ICU. DESIGN: Prospective, interventional, and multicenter study. SETTING: A total of 181 ICUs throughout Spain. PATIENTS: All patients admitted for more than 24 hours to the participating ICUs between April 1, 2011, and December 31, 2012. INTERVENTION: Ten ventilator-associated pneumonia prevention measures were implemented (seven were mandatory and three highly recommended). The database of the National ICU-Acquired Infections Surveillance Study (Estudio Nacional de Vigilancia de Infecciones Nosocomiales [ENVIN]) was used for data collection. Ventilator-associated pneumonia rate was expressed as incidence density per 1,000 ventilator days. Ventilator-associated pneumonia rates from the incorporation of the ICUs to the project, every 3 months, were compared with data of the ENVIN registry (April-June 2010) as the baseline period. Ventilator-associated pneumonia rates were adjusted by characteristics of the hospital, including size, type (public or private), and teaching (postgraduate) or university-affiliated (undergraduate) status. MEASUREMENTS AND MAIN RESULTS: The 181 participating ICUs accounted for 75% of all ICUs in Spain. In a total of 171,237 ICU admissions, an artificial airway was present on 505,802 days (50.0% of days of stay in the ICU). A total of 3,474 ventilator-associated pneumonia episodes were diagnosed in 3,186 patients. The adjusted ventilator-associated pneumonia incidence density rate decreased from 9.83 (95% CI, 8.42-11.48) per 1,000 ventilator days in the baseline period to 4.34 (95% CI, 3.22-5.84) after 19-21 months of participation. CONCLUSIONS: Implementation of the bundle measures included in the "Pneumonia Zero" project resulted in a significant reduction of more than 50% of the incidence of ventilator-associated pneumonia in Spanish ICUs. This reduction was sustained 21 months after implementation.
