Serotype distribution, clinical characteristics, and antimicrobial resistance of pediatric invasive pneumococcal disease in Colombia during PCV10 mass vaccination (2017-2022).

Introduction: Invasive Pneumococcal Disease (IPD) causes significant morbidity and mortality in children under 5 y. Colombia introduced PCV10 vaccination in 2012, and the Neumocolombia network has been monitoring IPD in pediatric patients since 2008. Materials and methods: This study is a secondary analysis of a prospective cohort involving pediatric patients with IPD admitted to 17 hospitals in Colombia, from January 1st, 2017, to December 31st, 2022. We present data on serotypes (Spn), clinical characteristics, and resistance patterns. Results: We report 530 patients, 215 (40.5%) were younger than 24 months. Among these, 344 cases (64.7%) presented with pneumonia, 95 (17.9%) with primary bacteremia, 53 (10%) with meningitis, 6 (1.1%) had pneumonia and meningitis, and 32 (6%) had other IPD diagnosis. The median hospital stay was 12 days (RIQ 8-14 days), and 268 (50.6%) were admitted to the ICU, of whom 60 (11.3%) died. Serotyping was performed in 298 (56.1%). The most frequent serotypes were Spn19A (51.3%), Spn6C (7.7%), Spn3 (6.7%), Spn6A (3.6%), and Spn14 (3.6%). Of 495 (93%) isolates with known susceptibility, 46 (9.2%) were meningeal (M) and 449 (90.7%) non-meningeal (NM). Among M isolates, 41.3% showed resistance to penicillin, and 21.7% decreased susceptibility to ceftriaxone. For NM isolates, 28.2% had decreased susceptibility to penicilin, and 24.2% decreased susceptibility to ceftriaxone. Spn19A showed the highest resistant to penicillin at 47% and was linked to multiresistance. Conclusion: The prevalence of PCV10-included serotypes decreased, while serotypes 19A and 6C increased, with Spn19A being associated with multiresistance. These findings had played a crucial role in the decision made by Colombia to modify its immunization schedule by switching to PCV13 in July 2022.

[Translated article] Pharmaceutical recommendations for therapeutic appropriateness in patients with multiple sclerosis.

OBJECTIVE: To determine the prevalence of PIMDINAC criteria and to implement pharmacological interventions in a population with multiple sclerosis over 55 years of age. METHODS: Retrospective, observational, open-label study, including patients with multiple sclerosis aged 55 years and older during December 2022 and February 2023. The main variable determined was the percentage of compliance with the PIMDINAC criteria. RESULTS: Ninety-five patients were included, with the presence of PIMDINAC criteria detected in 67.4%. The most frequently detected criterion was non-adherence to concomitant treatment (84.4%), followed by drug-drug interactions (56.2%) and potentially inappropriate medication (25%). A total of 20 pharmaceutical interventions were performed in 17 patients (17.9%). Potentially inappropriate medication was responsible for 11 interventions, non-adherence for 7, and drug-drug interactions for 2. The 81.8% of interventions were accepted, resulting in the discontinuation of 15 inappropriately prescribed drugs. The prevalence of PIMDINAC criteria in this group of patients is high. The study revealed that PIMDINAC criteria were prevalent in 67.4% of the study population, with polypharmacy playing an important role, suggesting the potential for a multidisciplinary approach, through pharmaceutical interventions to address unnecessary or duplicate treatments.

Association of renal function with mortality among hospitalized patients treated with remdesivir for COVID-19.

BACKGROUND AND AIM: Renal dysfunction is associated with poor outcomes in patients with coronavirus disease 2019 (COVID-19). In an effort to improve outcomes, intravenous remdesivir has been broadly used for the treatment of COVID-19 even in patients with low estimated glomerular filtration rate (eGFR). Our study assessed the residual risk of outcomes of patients with low eGFR despite treatment with remdesivir for COVID-19, during a timeframe prior to the expanded label across all levels of renal function. METHODS: We conducted an observational, retrospective, multi-site cohort study of adults hospitalized with COVID-19 treated with at least one dose of remdesivir between November 6, 2020, and November 5, 2021. Electronic medical records were reviewed to obtain patient characteristics, related laboratory data, and outcomes. The primary endpoint was all-cause mortality by day 28. Multivariable logistic regression was used to evaluate association between groups. RESULTS: The study population consisted of 3024 patients hospitalized with COVID-19 and treated with remdesivir. The median age was 67 [IQR 55, 77] years; 42.7% were women, and 88.6% were white. The median eGFR was 76.6 mL/min/1.73 m2 [IQR 52.5, 95.2]; the majority (67.2%) of patients had an eGFR ≥ 60, while 9% had an eGFR <30. All-cause mortality by day 28 was 8.7%. All-cause mortality rates were significantly higher among patients with impaired renal function (Odds Ratio [OR] 1.63 for patients with eGFR 30-59; OR 1.46 for eGFR 15-29; OR 2.42 for eGFR <15 and OR 5.44 for patients on dialysis) compared to patients with eGFR ≥60 mL/min/1.73m2. CONCLUSIONS: Lower eGFR remains an independent risk factor for mortality in COVID-19 even in patients treated with remdesivir.

Do 3D-printed and milled tooth-supported complete monolithic zirconia crowns differ in accuracy and fit? A systematic review and meta-analysis of in vitro studies.

STATEMENT OF PROBLEM: Additive (3-dimensional printing) and subtractive (milling) methods are digital approaches to fabricating zirconia restorations. Comparisons of their resultant fabrication accuracy and restoration fit are lacking. PURPOSE: The purpose of this systematic review and meta-analysis was to evaluate the accuracy and fit of monolithic zirconia crowns fabricated by 3-dimensional printing and milling. MATERIAL AND METHODS: The PubMed (Medline), Scopus, Embase, Web of Science, Cochrane Library, and Google Scholar databases were searched up to August 2023. Eligible records were included, and the standardized mean difference (SMD) analyzed 4 outcomes: marginal fit, intaglio fit, trueness, and precision. Publication bias was analyzed with Trim-and-fill, the Egger regression test, and Begg funnel plot. Methodological quality was rated using the QUIN tool. RESULTS: A total of 15 publications were found eligible out of the initial 6539 records. The 3-dimensional printing group demonstrated a lower marginal fit (SMD=1.46, 95% CI=[0.67, 2.26], P<.001; I2=83%, P<.001) and trueness (SMD=0.69, 95% CI=[0.20, 1.18], P=.006; I2=88%, P<.001) and a significantly higher precision (SMD=-2.19, 95% CI=[-2.90, -1.48], P<.001; I2=56%, P=.045). The intaglio fit did not differ significantly across the study groups (SMD=0.77, 95% CI=[-0.22, 1.77], P=.127; I2=87%, P<.001). CONCLUSIONS: Given the high degree of heterogeneity, it can be cautiously concluded that while 3-dimensional printing led to greater precision, the outcomes of the 2 accuracy and adaptation parameters most crucial to the longevity of the restorations-trueness and marginal fit-showed the superiority of the milling technique.

AI-driven translations for kidney transplant equity in Hispanic populations.

Health equity and accessing Spanish kidney transplant information continues being a substantial challenge facing the Hispanic community. This study evaluated ChatGPT's capabilities in translating 54 English kidney transplant frequently asked questions (FAQs) into Spanish using two versions of the AI model, GPT-3.5 and GPT-4.0. The FAQs included 19 from Organ Procurement and Transplantation Network (OPTN), 15 from National Health Service (NHS), and 20 from National Kidney Foundation (NKF). Two native Spanish-speaking nephrologists, both of whom are of Mexican heritage, scored the translations for linguistic accuracy and cultural sensitivity tailored to Hispanics using a 1-5 rubric. The inter-rater reliability of the evaluators, measured by Cohen's Kappa, was 0.85. Overall linguistic accuracy was 4.89 ± 0.31 for GPT-3.5 versus 4.94 ± 0.23 for GPT-4.0 (non-significant p = 0.23). Both versions scored 4.96 ± 0.19 in cultural sensitivity (p = 1.00). By source, GPT-3.5 linguistic accuracy was 4.84 ± 0.37 (OPTN), 4.93 ± 0.26 (NHS), 4.90 ± 0.31 (NKF). GPT-4.0 scored 4.95 ± 0.23 (OPTN), 4.93 ± 0.26 (NHS), 4.95 ± 0.22 (NKF). For cultural sensitivity, GPT-3.5 scored 4.95 ± 0.23 (OPTN), 4.93 ± 0.26 (NHS), 5.00 ± 0.00 (NKF), while GPT-4.0 scored 5.00 ± 0.00 (OPTN), 5.00 ± 0.00 (NHS), 4.90 ± 0.31 (NKF). These high linguistic and cultural sensitivity scores demonstrate Chat GPT effectively translated the English FAQs into Spanish across systems. The findings suggest Chat GPT's potential to promote health equity by improving Spanish access to essential kidney transplant information. Additional research should evaluate its medical translation capabilities across diverse contexts/languages. These English-to-Spanish translations may increase access to vital transplant information for underserved Spanish-speaking Hispanic patients.

Toxina botulínica y neumoperitoneo secuencial en el manejo de hernia inguinoescrotal gigante: Reporte de caso / Botulinum toxin and sequential pneumoperitoneum in the management of giant inguinoscrotal hernia: Case report

Introducción. Las hernias gigantes con pérdida de domicilio son aquellas cuyo saco herniario alcanza el punto medio del muslo en bipedestación y su contenido excede el volumen de la cavidad abdominal. Estas hernias son un reto quirúrgico dada la difícil reducción de su contenido y del cierre primario de la fascia. Tienen mayor riesgo de complicaciones asociadas al síndrome compartimental abdominal, así como mayor tasa de recurrencia y morbilidad en los pacientes. Caso clínico. Paciente masculino de 81 años, reconsultante por hernia inguinoescrotal derecha gigante, de dos años de evolución, sintomática, con índice de Tanaka de 24 %. Se decidió aplicar el protocolo de neumoperitoneo secuencial (hasta 11.000 ml en total en cavidad) además de toxina botulínica en pared abdominal (dos sesiones). Resultados. Se logró la corrección exitosa de la hernia inguinoescrotal gigante, sin recaídas de su patología abdomino-inguinal. El paciente manifestó satisfacción con el tratamiento un año después del procedimiento. Conclusiones. El protocolo de neumoperitoneo secuencial es una alternativa en casos de hernias complejas, con alto riesgo de complicaciones, que requieren técnicas reconstructivas adicionales. La aplicación previa de toxina botulínica es un adyuvante considerable para aumentar la probabilidad de resultados favorables. Sin embargo, debe incentivarse la investigación en esta área para evaluar su efectividad.

Introduction. Giant hernias with loss of domain are those whose hernial sac reaches the midpoint of the thigh in standing position and whose content exceeds the volume of the abdominal cavity. These hernias are a surgical challenge given the difficult reduction of their contents and the primary fascial closure, with a higher risk of complications associated with abdominal compartment syndrome, as well as a higher rate of recurrence and morbidity in patients. Clinical case. A 81-year-old male patient with comorbidity, reconsulting due to a symptomatic giant right inguinoscrotal hernia of two years of evolution, with a Tanaka index of 24%, eligible for a sequential pneumoperitoneum protocol (up to a total of 11,000 cc in cavity) plus application of botulinum toxin (two sessions) in the abdominal wall. Results. Successful correction of the patient's giant inguinoscrotal hernia was achieved using this protocol, without recurrence of his abdomino-inguinal pathology and satisfaction with the procedure after one year. Conclusion. The sequential pneumoperitoneum protocol continues to be an important alternative in cases with a high risk of complications that require additional reconstructive techniques, while the previous application of botulinum toxin is a considerable adjuvant to further increase the rate of favorable results. However, research in the area should be encouraged to reaffirm its effectiveness.

Performance of posterior third-generation monolithic zirconia crowns in a complete digital workflow: A three-year prospective clinical study.

Background/purpose: Translucent monolithic zirconia restorations have recently introduced. The purpose of this study was to evaluate the clinical behavior and the survival rate of the posterior third-generation monolithic zirconia crowns (MZCs) during three years of clinical service. Materials and methods: Twenty-four patients who needed thirty crowns were enrolled in this study. Digital impressions were made, and the crowns were milled and cemented with a resin cement. The crowns outcomes were assessed using the California Dental Association's (CDA) criteria. Gingival index (GI), plaque index (PI), and periodontal probing depth (PPD) for MZCs and contralateral natural teeth (control) were assessed. Margin index (MI) for MZCs was also assessed. Data analysis was conducted using the Wilcoxon signed-rank and the Friedman tests. Results: The 3-year survival rate was 100%. All MZCs were rated as satisfactory throughout the follow-up period, and no biological or mechanical complications were observed. No differences were recorded when GI, PI and PPD at 3-year of follow-up were compared to baseline. No differences were recorded between crowned and control teeth. The MI remained stable throughout the study period. Conclusion: The third-generation monolithic zirconia appears to be a good treatment option for the rehabilitation of posterior single teeth.

Comparable outcomes of outpatient remdesivir and sotrovimab among high-risk patients with mild to moderate COVID-19 during the omicron BA.1 surge.

Studies conducted prior to SARS-CoV-2 Omicron demonstrated that sotrovimab and remdesivir reduced hospitalization among high-risk outpatients with mild to moderate COVID-19. However, their effectiveness has not been directly compared. This study examined all high-risk outpatients with mild to moderate COVID-19 who received either remdesivir or sotrovimab at Mayo Clinic during the Omicron BA.1 surge from January to March 2022. COVID-19-related hospitalization or death within 28 days were compared between the two treatment groups. Among 3257 patients, 2158 received sotrovimab and 1099 received remdesivir. Patients treated with sotrovimab were younger and had lower comorbidity but were more likely to be immunocompromised than remdesivir-treated patients. The majority (89%) had received at least one dose of COVID-19 vaccine. COVID-19-related hospitalization (1.5% and 1.0% in remdesivir and sotrovimab, respectively, p = .15) and mortality within 28 days (0.4% in both groups, p = .82) were similarly low. A propensity score weighted analysis demonstrated no significant difference in the outcomes between the two groups. We demonstrated favorable outcomes that were not significantly different between patients treated with remdesivir or sotrovimab.

Pharmaceutical recommendations for therapeutic appropriateness in multiple sclerosis patients. / Recomendaciones farmacéuticas de adecuación terapéutica en pacientes con esclerosis múltiple.

OBJECTIVE: To determine the prevalence of PIMDINAC criteria and to implement pharmacological interventions in a population with multiple sclerosis over 55 years of age. METHODS: Retrospective observational open-label study including patients with multiple sclerosis aged 55 years and older between December 2022 and February 2023. The main variable determined was the percentage of compliance with the PIMDINAC criteria. RESULTS: Ninety-five patients were included, with the presence of PIMDINAC criteria detected in 67.4%. The most frequently detected criterion was non-adherence to concomitant treatment (84,4%), followed by drug-drug interactions (56.2%) and potentially inappropriate medication (25%). A total of 20 pharmaceutical interventions were performed in 17 patients (17.9%). Potentially inappropriate medication was responsible for 11 interventions, non-adherence for 7 and drug-drug interactions for 2. The 81.8% of interventions were accepted, resulting in the discontinuation of 15 inappropriately prescribed drugs. The prevalence of PIMDINAC criteria in this group of patients is high. The study revealed that PIMDINAC criteria were prevalent in 67.4% of the study population, with polypharmacy playing an important role, suggesting the potential for a multidisciplinary approach, through pharmaceutical interventions to address unnecessary or duplicate treatments.

Children with cancer at the end of life in a middle-income country: integrated pediatric palliative care improves outcomes.

BACKGROUND: In 2020, the Global Cancer Observatory reported 280,000 cases of childhood cancer worldwide, with a higher burden of disease and mortality rates in low- and middle-income countries. In 2022, the National Institute of Health reported 1708 new cases of childhood cancer in Colombia and an overall survival rate of approximately 55%. The aim of this study is to compare outcomes in children with cancer in the hospital setting during the last 72 h of life who received concurrent Pediatric Palliative Care (PPC) versus oncology care alone. METHODS: An observational descriptive study was conducted between January 2013 and June 2022 in a center for pediatric patients with oncological diagnoses. In 2017, the PPC team was created. Patients between 28 days and 17 years of age who were hospitalized at least 72 h before death were included. A retrospective review of the medical records of patients in the last 72 h of life was performed. Two cohorts were established: oncology-alone group received exclusive management by oncology, and oncology and PPC received concurrent oncology and PPC management since the diagnosis. RESULTS: We evaluated 257 medical records of deceased pediatric patients with cancer diagnoses. For the first cohort (2013-2017), 136 patients were included; for the second cohort (2018 and 2022), 121 patients were evaluated. The most frequent diagnosis was leukemia [47.1% (n = 121)]. No significant difference was found in either group between dyspnea, pain, and seizures. Dyspnea was the most frequent symptom in both groups. Agitation and anxiety were reported more frequently in children from the oncology-alone group (22.1% and 13.2%, respectively). The oncology and PPC group received more psychology and social work consultation (94.2% and 70.2% vs. 84.6 and 54.4% in the oncology alone group) and had a higher percentage of advance care planning (79.3% vs. 62.5% in the oncology alone group). CONCLUSIONS: This retrospective study highlights that PPC at the end of life (EoL) offers a holistic approach to the physical and psychosocial symptoms experienced by children with cancer; these patients received more comfort through symptom management and less aggressive treatment at the EoL. The availability of a PPC team may contribute to improvements in the quality of end-of-life care. TRIAL REGISTRATION: retrospectively registered.

Divergent changes in PBN excitability in a mouse model of neuropathic pain.

The transition from acute to chronic pain involves maladaptive plasticity in central nociceptive pathways. Growing evidence suggests that changes within the parabrachial nucleus (PBN), an important component of the spino-parabrachio-amygdaloid pain pathway, are key contributors to the development and maintenance of chronic pain. In animal models of chronic pain, PBN neurons become sensitive to normally innocuous stimuli and responses to noxious stimuli become amplified and more often produce after-discharges that outlast the stimulus. Using ex vivo slice electrophysiology and two mouse models of neuropathic pain, sciatic cuff and chronic constriction of the infraorbital nerve (CCI-ION), we find that changes in the firing properties of PBN neurons and a shift in inhibitory synaptic transmission may underlie this phenomenon. Compared to PBN neurons from shams, a larger proportion of PBN neurons from mice with a sciatic cuff were spontaneously active at rest, and these same neurons showed increased excitability relative to shams. In contrast, quiescent PBN neurons from cuff mice were less excitable than those from shams. Despite an increase in excitability in a subset of PBN neurons, the presence of after-discharges frequently observed in vivo were largely absent ex vivo in both injury models. However, GABAB-mediated presynaptic inhibition of GABAergic terminals is enhanced in PBN neurons after CCI-ION. These data suggest that the amplified activity of PBN neurons observed in rodent models of chronic pain arise through a combination of changes in firing properties and network excitability.Significance Statement Hyperactivity of neurons in the parabrachial nucleus (PBN) is causally linked to exaggerated pain behaviors in rodent models of chronic pain but the underlying mechanisms remain unknown. Using two mouse models of neuropathic pain, we show the intrinsic properties of PBN neurons are largely unaltered following injury. However, subsets of PBN neurons become more excitable and GABAB receptor mediated suppression of inhibitory terminals is enhanced after injury. Thus, shifts in network excitability may be a contributing factor in injury induced potentiation of PBN activity.

GABA release from central amygdala neurotensin neurons differentially modulates ethanol consumption in male and female mice.

The central nucleus of the amygdala is known to play key roles in alcohol use and affect. Neurotensin neurons in the central nucleus of the amygdala have been shown to regulate alcohol drinking in male mice. However, little is known about which neurotransmitters released by these cells drive alcohol consumption or whether these cells drive alcohol consumption in female mice. Here we show that knockdown of GABA release from central amygdala neurotensin neurons using a Nts-cre-dependent vGAT-shRNA-based AAV strategy reduces alcohol drinking in male, but not female, mice. This manipulation did not impact avoidance behavior, except in a fasted novelty-suppressed feeding test, in which vGAT shRNA mice demonstrated increased latency to feed on a familiar high-value food reward, an effect driven by male mice. In contrast, vGAT shRNA female mice showed heightened sensitivity to thermal stimulation. These data show a role for GABA release from central amygdala neurotensin neurons in modulating consumption of rewarding substances in different motivational states.

Digital workflow for monolithic and veneered zirconia and metal-ceramic posterior fixed partial dentures: A five-year prospective randomized clinical trial.

Purpose To evaluate and compare the survival, success rates, and biological and technical complications of three-unit posterior monolithic and veneered zirconia and metal-ceramic (MC) posterior fixed partial dentures (FPDs) fabricated using a digital workflow and computer-aided design and computer-aided manufacturing (CAD/CAM) over a 5-year follow-up.Methods Ninety patients in need of three-unit posterior FPDs were randomized to receive monolithic zirconia (MZ), veneered zirconia (VZ), and MC restorations (n = 30 each). Teeth preparations were scanned using an intraoral scanner, and restorations were milled and cemented with resin cement. Clinical performance and periodontal parameters were assessed at baseline and yearly up to 5 years after insertion. Data analysis was performed using the Kaplan-Meier method, Friedman test, and Wilcoxon signed-rank test with Bonferroni correction and Mann-Whitney U test.Results The 5-year survival rates of the MZ, VZ, and MC FPDs were 87%, 97%, and 100%, respectively (P = 0.04). Most complications were biological in nature. Only one MZ FPD fractured 58 months after placement. All the restorations were assessed as satisfactory at each recall. Differences were found in the gingival index score over time in the VZ and MC groups. The margin index remained stable throughout the follow-up period in both zirconia groups.Conclusions The results of this study suggest that using a digital workflow to fabricate posterior FPDs is an adequate treatment option and that monolithic zirconia could be a viable alternative to metal-ceramic or veneered zirconia. However, further long-term studies are necessary to provide stronger evidence in patients with bruxism.

Evaluation of the Renal Angina Index to Predict the Development of Acute Kidney Injury in Children With Sepsis Who Live in Middle-Income Countries.

OBJECTIVE: The renal angina index (RAI) provides a clinically feasible and applicable tool to identify critically ill children at risk of severe acute kidney injury (AKI) in high-income countries. Our objective was to evaluate the performance of the RAI as a predictor of the development of AKI in children with sepsis in a middle-income country and its association with unfavorable outcomes. METHODS: This is a retrospective cohort study in children with sepsis hospitalized in the pediatric intensive care unit (PICU) between January 2016 and January 2020. The RAI was calculated 12 hours after admission to predict the development of AKI and at 72 hours to explore its association with mortality, the need for renal support therapy, and PICU stay. RESULTS: We included 209 PICU patients with sepsis with a median age of 23 months (interquartile range, 7-60). We found that 41.1% of the cases (86/209) developed de novo AKI on the third day of admission (KDIGO 1, 24.9%; KDIGO 2, 12.9%; and KDIGO 3, 3.3%).Overall mortality was 8.1% (17/209), higher in patients with AKI (7.7% vs 0.5%, P < 0.01). The RAI on admission was able to predict the presence of AKI on day 3 (area under the curve (AUC), 0.87; sensitivity, 94.2%; specificity, 100%; P < 0.01), with a negative predictive value greater than 95%. An RAI greater than 8 at 72 hours was associated with a greater risk of mortality (adjusted odds ratio [aOR], 2.6; 95% confidence interval [CI], 2.0-3.2; P < 0.01), a need for renal support therapy (aOR, 2.9; 95% CI, 2.3-3.6; P < 0.01), and a PICU stay of more than 10 days (aOR, 1.54; 95% CI, 1.1-2.1; P < 0.01). CONCLUSIONS: The RAI on the day of admission is a reliable and accurate tool for predicting the risk of developing AKI on day 3, in critically ill children with sepsis in a limited resource context. A score greater than eight 72 hours after admission is associated with a higher risk of death, the need for renal support therapy, and PICU stay.

Successful Liberation from Acute Kidney Replacement Therapy in Critically Ill Patients: A Prospective Cohort Study.

INTRODUCTION: Recovery of kidney function to liberate patients from acute kidney replacement therapy (AKRT) is recognized as a vital patient-centered outcome. The lack of specific guidelines providing specific recommendations on therapy interruption is an important obstacle. We aimed to determine the prevalence of successful discontinuation of AKRT and its predictive factors after the elaboration of clinical protocol with these recommendations. METHODOLOGY: A prospective cohort study was performed with 156 patients at a public Brazilian university hospital between July 2020 and July 2021. RESULTS: Success and hospital discharge were achieved for most patients (84.6% and 89%, respectively). Multivariable logistic regression analysis showed that C-reactive protein (CRP), urine output, and creatinine clearance at the time of interruption were variables associated with discontinuation success (OR: 0.943, CI: 0.905-0.983, p = 0.006; OR: 1.078, CI: 1.008-1.173, p = 0.009 and OR: 1.091, CI: 1.012-1.213, p = 0.004; respectively). The areas under the curve for CRP, urine output, and creatinine clearance at the time of interruption were 0.78, 0.62, and 0.82, respectively. Both CRP and creatinine clearance were good predictors of successful liberation of AKRT. The optimal cutoff value of them had sensitivity and specificity of 0.88 and 0.87, 0.91 and 0.90, respectively. The use of noradrenalin at the time of interruption (OR: 0.143, CI: 0.047-0.441, p = 0.001) and successful discontinuation (OR: 3.745, CI: 1.047-13.393, p = 0.042) were identified as variables associated with hospital discharge. CONCLUSION: Our results show the factors related to success in discontinuing AKRT are the CRP, creatinine clearances, and urinary output at the time of AKRT interruption and it was associated with lower mortality.

The parabrachial to central amygdala pathway is critical to injury-induced pain sensitization in mice.

The spino-ponto-amygdaloid pathway is a major ascending circuit relaying nociceptive information from the spinal cord to the brain. Potentiation of excitatory synaptic transmission in the parabrachial nucleus (PBN) to central amygdala (CeA) pathway has been reported in rodent models of persistent pain. However, the functional significance of this pathway in the modulation of the somatosensory component of pain was recently challenged by studies showing that spinal nociceptive neurons do not target CeA-projecting PBN cells and that manipulations of this pathway have no effect on reflexive-defensive somatosensory responses to peripheral noxious stimulation. Here, we showed that activation of CeA-projecting PBN neurons is critical to increase both stimulus-evoked and spontaneous nociceptive responses following an injury in male and female mice. Using optogenetic-assisted circuit mapping, we confirmed a functional excitatory projection from PBN→CeA that is independent of the genetic or firing identity of CeA cells. We then showed that peripheral noxious stimulation increased the expression of the neuronal activity marker Fos in CeA-projecting PBN neurons and that chemogenetic inactivation of these cells decreased behavioral hypersensitivity in models of neuropathic and inflammatory pain without affecting baseline nociception. Lastly, we showed that chemogenetic activation of CeA-projecting PBN neurons is sufficient to induced bilateral hypersensitivity without injury. Together, our results indicate that the PBN→CeA pathway is a key modulator of pain-related behaviors that can increase reflexive-defensive and affective-motivational responses to somatosensory stimulation in injured states without affecting nociception under normal physiological conditions.

Immediate Loading of Zygomatic Implants Using a Dual Scan Technique.

The immediate loading protocol has become increasingly popular due to the progressive growth in demand for a reduction in treatment times. The possibility of applying this protocol would depend on certain important factors. The application of the digital workflow mentioned in the protocol guarantees rapidity, precision, and esthetics. This report aims to describe a fully digital workflow using a dual scan impression technique to fabricate immediate fixed complete dentures (FCDs) for zygomatic and standard implants. A 58-year-old female patient requested treatment for her severely atrophic maxilla, and four unrehabilitated implants in the mandible. After proper diagnosis and planification, four zygomatic implants and two standard implants were placed. During the surgery, transmucosal abutments were placed on all implants. After suturing, the positions of the implants were recorded using a stereophotogrammetric technique, creating a standard tessellation (STL) file. In the lower arch, the second phase of the surgery was carried out: the transmucosal abutments were placed, and then the implant positions were recorded in the same way. The soft tissues were rescanned after suturing with an intraoral scanner (IOS), and all STL files were aligned to obtain the virtual final models. The pre-design after virtual modifications was aligned with the definitive models. The provisional prostheses were milled and placed after six hours after the surgery, and the definitive prostheses were placed six months after the surgery. The dual scan technique used obtained a precise fit for both the provisional and definitive FCDs. This technique might be an effective and reliable alternative for the fabrication of immediate and definitive screw-retained FCDs in a completely digital workflow. The time taken for scanning and fabrication was reduced, and the clinician's and patient's satisfaction were improved.

Método: Utilizamos las recomendaciones CARE para el reporte de casos clínicos. Caso clínico: Hombre de 45 años previamente sano, con debilidad aguda de la extremidad torácica derecha sin causa aparente. La tomografía simple de cráneo no evidenció alteraciones. La resonancia magnética mostró una oclusión completa de la arteria carótida interna en todos sus segmentos y disminución del flujo de la arteria cerebral media izquierda. La evolución clínica fue desfavorable. Conclusión: La disección carotídea debe sospecharse en personas con EVC sin factores de riesgo cardiovascular.

Abstract Introduction: Carotid dissection consists of a tear in the vessel wall. It is a rare pathology, but it is the most common cause of ischemic cerebral vascular disease (CVD) in people under 45 years of age. The clinical manifestations are very variable. Method: We used CARE recommendations for reporting clinical cases. Clinical case: Previously, a healthy 45-year-old man with acute weakness of the right thoracic extremity without apparent cause. The simple skull tomography did not show any alterations. MRI showed complete occlusion of the internal carotid artery in all its segments and decreased flow of the left middle cerebral artery. The clinical evolution was unfavorable. Conclusion: Carotid dissection should be suspected in people with CVD without cardiovascular risk factors.

Third National Registry of Cardiac Rehabilitation Programs in Mexico (RENAPREC III-2022) / Tercer Registro Nacional de Programas de Rehabilitación Cardiaca en México (RENAPREC III-2022)

Abstract Introduction: In Mexico, cardiac rehabilitation (CR) as an interdisciplinary intervention with therapeutic impact in patients with heart disease is growing. There is the need to know actual conditions of CR in our country. Objectives: The objective of this National Registry is to follow-up those existing and new CR units in Mexico through the comparison between the two previous registries, RENAPREC-2009 and RENAPREC II-2015 studies. This is a descriptive study focused on diverse CR activities such as assistance training, and certification of health professionals, barriers, reference, population attended, interdisciplinarity, permanence over time, growth prospects, regulations, post-pandemic condition, integrative characteristics, and scientific research. Results: Data were collected from 45 CR centers in the 32 states, 75.5% are private practice units, 67% are new, 33% were part of RENAPREC II-2015, and 17 have continued since 2009. With a better distribution of CR units along the territory, the median reference of candidates for CR programs is 9% with a significant reduction into tiempo of enrollment to Phase II admission (19 ± 11 days). Regarding to previous registries, the coverance of Phases I, II, and III is 71%, 100%, and 93%, respectively; and a coverance increases in evaluation, risk stratification, and prescription, more comprehensive attendance and prevention strategies. Conclusions: CR in Mexico has grown in the past 7 years. Even there is still low reference and heterogeneity in specific processes, there are strengths such as interdisciplinarity, scientific professionalization of specialists, national diversification, and an official society that are consolidated over time.

Development and Implementation of DIALOG+S in the School Setting as a Tool for Promoting Adolescent Mental Well-Being and Resilience in a Post-Armed Conflict Area in Colombia: Exploratory Cluster Randomized Controlled Trial.

BACKGROUND: Educational settings are ideal for promoting mental well-being and resilience in children. The challenges of the COVID-19 pandemic made evident the important role that teachers and school counselors play in the mental health of their students. Therefore, it is imperative to develop and implement cost-effective interventions that allow them to identify and address mental health problems early, especially in post-armed conflict areas, to reduce the burden of mental disorders in this population. OBJECTIVE: This study aimed to adapt an existing patient-focused digital intervention called DIALOG+ from an adult clinical setting to an adolescent educational setting and to assess the feasibility, acceptability, and estimated effect of implementing this intervention as a tool for promoting quality of life, mental well-being, and resilience. METHODS: We conducted an exploratory mixed methods study in 2 public schools in postconflict areas in Tolima, Colombia. This study was conducted in 3 phases. In the adaptation phase, focus groups were conducted with students and teachers to identify changes required in DIALOG+ for it to be used in the school setting. The exploration phase consisted of an exploratory cluster randomized controlled trial. A total of 14 clusters, each with 1 teacher and 5 students, were randomly allocated to either the experimental (DIALOG+S) group or to an active control group (counseling as usual). Teachers in both groups delivered the intervention once a month for 6 months. Through screening scales, information was collected on mental health symptoms, quality of life, self-esteem, resilience, and family functionality before and after the intervention. Finally, the consolidation phase explored the experiences of teachers and students with DIALOG+S using focus group discussions. RESULTS: The changes suggested by participants in the adaptation phase highlighted the central importance of the school setting in the mental health of adolescents. In the exploratory phase, 70 participants with a mean age of 14.69 (SD 2.13) years were included. Changes observed in the screening scale scores of the intervention group suggest that the DIALOG+S intervention has the potential to improve aspects of mental health, especially quality of life, resilience, and emotional symptoms. The consolidation phase showed that stakeholders felt that using this intervention in the school setting was feasible, acceptable, and an enriching experience that generated changes in the perceived mental health and behavior of participants. CONCLUSIONS: Our results are encouraging and show that the DIALOG+S intervention is feasible and acceptable as a promising opportunity to promote well-being and prevent and identify mental health problems in the school context in a postconflict area in Colombia. Larger, fully powered studies are warranted to properly assess the efficacy and potential impact of the intervention and to refine implementation plans.
