Efficiency, Economy and Excellence: Experimental Exploration of Evidence-based Guideline Development in Resource-Constrained Settings

Development of clinical practice guidelines is a scientific process based on a thorough review and appraisal of the global evidence, but factoring in local contextually relevant issues. It is highly resource intensive, demanding considerable time, human skills, and finances- making it challenging in resource-constrained settings. This article summarizes a unique attempt to develop evidence-based guidelines in such settings. This was made possible by mentoring and monitoring a group of committed healthcare professionals with limited prior expertise in evidence-based guideline development. The various steps included an online training workshop to build knowledge and skills. This was followed by a systematic process of identifying topics requiring evidence-based guidelines. Thereafter, the topics were prioritized through a Delphi process. Formal clinical questions were framed using the PICOTS (Patient/ Population, Intervention/ Exposure, Comparison, Outcome, Time-frame, Setting) format. The guideline development process was made time and resource efficient by starting with a formal search for existing guidelines whose recommendations could be adopted, adapted, or adoloped to the local setting. If such guidelines were unavailable, high quality secondary evidence (systemic reviews) was accessed to find answers to the clinical questions. If unavailable, de novo systematic reviews of primary research studies were undertaken. The evidence base was critically appraised and graded. Formal evidence-to-decision formats were used to enable translation of the evidence to recommendations implementable in the local setting. The entire guideline development process was completed with zero financial allocation. This model focusing on efficiency, economy, and excellence, can be emulated in diverse resource-constrained settings.

Serum Periostin Level in Children with Asthma

Objectives To determine the average serum periostin level in children with asthma between 6 and 16 y of age, and to fnd out if the levels correlated with markers of eosinophilic infammation, asthma control, and severity. Methods Children under follow-up at a tertiary care centre were enrolled. Children with conditions causing elevated serum periostin other than asthma, or history of systemic steroid use in the past 6 mo were excluded. Serum total IgE and periostin were estimated by ELISA. Results The median (IQR) serum periostin level was 52.6 (45.4, 58.3) ng/mL. Levels did not vary with age, gender, duration of symptoms, positive family history, or history of exacerbations in the last 6 mo. There was no signifcant correlation with anthropometric parameters or their z scores, or markers of eosinophilic infammation in blood including serum total IgE, eosinophil percentage or absolute eosinophil count. There was no diference in median periostin levels of children with diferent asthma symptom control or asthma severity. Conclusions In a group of 26 Indian children with physician-diagnosed asthma, serum periostin showed no signifcant correlation to markers of eosinophilic infammation.

Epidemiology, Clinical Profile, Intensive Care Needs and Outcome in Children with SARS-CoV-2 Infection Admitted to a Tertiary Hospital During the First and Second Waves of the COVID-19 Pandemic in India

Objectives To compare the epidemiological, clinical profle, intensive care needs and outcome of children hospitalized with SARS-CoV-2 infection during the frst and second waves of the pandemic. Methods This was a retrospective study of all children between 1 mo and 14 y, admitted to a dedicated COVID-19 hospital (DCH) during the frst (1st June to 31st December 2020) and second waves (1st March to 30th June 2021). Results Of 217 children, 104 (48%) and 113 (52%) were admitted during the frst and second waves respectively. One hundred ffty-two (70%) had incidentally detected SARS-CoV-2 infection, while 65 (30%) had symptomatic COVID-19. Comorbidities were noted in 137 (63%) children. Fifty-nine (27%) and 66 (30%) children required high-dependency unit (HDU) and ICU care respectively. Severity of infection and ICU needs were similar during both waves. High-fow oxygen (n=5, 2%), noninvasive ventilation [CPAP (n=34, 16%) and BiPAP (n=8, 5%)] and invasive ventilation (n=45, 21%) were respiratory support therapies needed. NIV use was more during the second wave (26% vs. 13%; p=0.02). The median (IQR) length (days) of DCH stay among survivors was longer during the frst wave [8 (6–10) vs. 5.5 (3–8); p=0.0001]. Conclusions Disease severity, associated comorbidities, PICU and organ support need and mortality were similar in the frst and second waves of the pandemic. Children admitted during the second wave were younger, had higher proportion of NIV use and shorter length of COVID-19 hospital stay.

Evidence-practice gap in treatment recommendations for proximal caries among Brazilian dentists / Lacuna entre a evidência e a prática nas recomendações de tratamento para cárie proximal entre dentistas brasileiros

ABSTRACT Little is known about how Brazilian dentists' treatment decisions for proximal carious lesions are compared to current evidence-based recommendations, so better understanding is needed to close any potential evidence-practice gap. Objectives: This cross-sectional study aimed to quantify the evidence-practice gap about proximal carious lesions treatment and identify dentist factors associated with this evidence-practice gap. Methods: Brazilian dentists (n=214) from Araraquara, São Paulo State, "completed a questionnaire about their dentist and practice characteristics and a translated version of the "Assessment of Caries Diagnosis and Caries Treatment" from the U.S. National Dental Practice-Based Research Network. Five radiographic images of proximal carious lesions in low-risk and high-risk patient scenarios were used. Associations between treatment recommendations and lesion, dentist, and practice characteristics were tested for statistical significance (p<0.05). Results: Lesions confined to the enamel would be restored by 35% and 71% of dentists in the low-risk and high-risk patient scenarios, respectively, suggesting a substantial evidence-practice gap given that surgical intervention of enamel lesions is not consistent with current evidence. The lesion depth threshold to recommend a permanent restoration differed between the low-risk and high-risk patient scenarios (p<0.001). Specific dentist/practice characteristics (dentist gender, graduate of a public dental school, postgraduate training, use of caries risk assessment) were significantly associated with the evidence-practice gap, but the magnitude of these differences was not major Conclusion: A substantial evidence-practice gap in treatment of proximal carious lesions was found for the sample overall, even when clinical scenarios presented low-risk patients. Global strategies are needed to close this substantial evidence-practice gap.

RESUMO Pouco se sabe se as decisões de tratamento dos dentistas brasileiros para lesões cariosas proximais são comparadas às recomendações atuais baseadas em evidências, portanto, é necessário um melhor entendimento para fechar qualquer potencial lacuna entre a evidência e a prática. Purpose: Este estudo transversal teve como objetivo quantificar a lacuna entre a evidência e a prática na decisão de tratamento das lesões cariosas proximais e identificar os fatores associados a essa lacuna entre a evidência e a prática. Methods: Cirurgiões-dentistas brasileiros (n=214) de Araraquara, Estado de São Paulo, preencheram um questionário sobre suas características odontológicas e clínicas e uma versão traduzida do "Assessment of Caries Diagnosis and Caries Treatment" da U.S. National Dental Practice-Based Research Network. Cinco imagens radiográficas de lesões cariosas proximais em cenários de pacientes de baixo risco e alto risco foram usadas. Associações entre recomendações de tratamento e lesão, dentista e características da prática foram testadas (p<0,05). Results: As lesões confinadas ao esmalte seriam restauradas por 35% e 71% dos dentistas nos cenários de pacientes de baixo risco e alto risco, respectivamente, sugerindo uma lacuna entre a evidência e a prática substancial, dado que a intervenção cirúrgica das lesões do esmalte não é consistente com as evidências atuais. O limiar de profundidade da lesão para recomendar uma restauração permanente diferiu entre os cenários de pacientes de baixo risco e alto risco (p<0,001). Características específicas do dentista/prática (sexo do dentista, graduado em uma faculdade pública, pós-graduação, uso da avaliação de risco de cárie) foram significativamente associadas à lacuna entre a evidência e a prática, mas a magnitude dessas diferenças não foi importante. Conclusions: uma lacuna entre a evidência e a prática substancial na decisão de tratamento de lesões cariosas proximais foi encontrada para a amostra como um todo, mesmo quando os cenários clínicos apresentavam pacientes de baixo risco. Estratégias globais são necessárias para fechar essa lacuna entre a evidência e a prática.

Evidence-practice gap in treatment decisions about defective composite and amalgam restorations among Brazilian dentists

Better understanding of dentists' decision-making about defective restorations is needed to close the evidence-practice gap (EPG). This study aimed to quantify the EPG about defective restorations and identify dentist factors associated with this EPG. Methods: 216 dentists from São Paulo State, Brazil, completed a questionnaire about three clinical case scenarios involving defective composite restorations with cementum-dentin margins (case 1) and enamel margins (case 2), and an amalgam (case 3) restoration. Dentists were asked what treatment, if any, they would recommend, including preventive treatment, polishing, re-surfacing, or repairing the restoration, or replacing the entire restoration. Replacing the entire restoration in any of these three scenarios was classified as inconsistent with the evidence, comprising an EPG. Bivariate analyses using Chi-square, ANOVA, or multiple comparison tests were performed (p<.05). Results: for defective composite restorations, 49% and 55% of dentists chose to replace the entire restoration for cases 1 and 2, respectively. Twenty-nine percent of dentists chose to replace the entire amalgam restoration. Dentists were significantly more likely to choose to replace the defective amalgam restoration than the composite restoration with a defect at the cementum-dentin margins or the enamel margins (both at p < .001). Female dentists were more likely to choose a conservative treatment than male dentists for cases 1 (p=.034) and 2 (p=.009). Dentists with a higher percentage of patients interested in individualized caries prevention were also more conservative in case 1 (p=.045). Conclusion: a substantial EPG regarding treatment decisions for defective restorations exists, especially for composite restorations. This study adds to the international evidence that an EPG exists in this clinical area and that global strategies need to be developed to close the gap

Correlation on the level of adherence to self-care activities and blood glucose control of adult patients with type 2 diabetes mellitus seen in the Outpatient Department of a tertiary hospital in Baguio City – A cross-sectional study

Introduction@#Type 2 Diabetes Mellitus (T2DM) remains one of the leading causes of mortality in the Philippines. Studies have reported that good adherence to self-care activities significantly aid in glycemic control. However, previous studies revealed a low adherence to diabetes self-care activities. Moreover, only few studies were done in the local setting assessing the level of adherence to self-care activities and correlating the two; hence, the immense need for the assessment of level of adherence to self-care activities among patients with T2DM.@*Objective@#This study aims to determine the level of adherence to self-care activities and correlate it with the glycemic control among T2DM patients seen in the outpatient department in a tertiary hospital in Baguio City.@*Methods@#This cross-sectional study was done using a survey questionnaire adapted from the Summary Diabetes Self-Care Activities Questionnaire version 2000. Glycemic control was determined using the latest valid HbA1c results. One hundred adult diabetic patients were included in the study. Participants were selected in the Family Medicine and Internal Medicine OPD Clinics through systematic random sampling method. Data collected were analyzed using descriptive and inferential statistics.@*Results@#Results revealed that majority of the sample population had undesirable self-care activity (69%), and poor glycemic control (69%). Statistical analysis revealed that proper adherence to either exercise (0.003) or compliance to medications (0.012) both have a significant relationship with glycemic control. Overall score (0.003) on one hand revealed a highly significant relationship with glycemic control.@*Conclusion@#Incorporating the different self-care activities namely diet, exercise, blood sugar testing, foot care, smoking cessation, and compliance to medication all together has a significant relationship with glycemic control among diabetic patients. Clinicians must emphasize proper adherence to self-care activities because of the high number of patients with undesirable self-care activities.

COVID-19 vaccine hesitancy among healthcare workers in two general hospitals in Benguet: A cross-sectional study

Background@#Baguio General Hospital and Medical Center (BGHMC) and Benguet General Hospital (BeGH) started COVID-19 vaccination among its employees in March 2021. Although there was an observed substantial increase in vaccine acceptance, a better understanding on the factors associated with hesitancy toward COVID-19 vaccine is necessary to further strengthen efforts and focus on the caveats regarding vaccine acceptance.@*Objective@#The study aimed to determine the factors influencing COVID-19 vaccine hesitancy among healthcare workers (HCW) in two general hospitals in Benguet.@*Methods@#A cross-sectional study was conducted among HCW in BGHMC and BeGH for 1 month. Total enumeration sampling was used which included 222 participants but only 85 responded. A modified questionnaire was used to describe the factors influencing COVID-19 vaccine hesitancy. Categorical variables were presented as frequencies and percentages. Pearson’s Chisquare test was used to observe the association between clinicodemographic factors and COVID-19 vaccine hesitancy among the HCW in BGHMC and BeGH.@*Results@#The results showed that young, female, non-clinical workers with direct contact with COVID-19 patients, previous COVID-19 infection, and without comorbidities were more likely to be hesitant. The study identified various internal, external, and vaccination-specific factors that influenced vaccine hesitancy, such as concerns about adverse effects, their impending risk in contracting COVID-19 at workplace, and thoughts about yearly booster dose. These findings suggest that vaccine hesitancy among healthcare workers in the Philippines is complex and influenced by a range of factors.@*Conclusion@#The study can be used to develop targeted interventions to address concerns about vaccine hesitancy and improve vaccine uptake among healthcare workers. The development of an equitable approach such as an effective and inclusive vaccine policy that does not feel mandatory for this population will foster trust in the healthcare system.

Telemedicine use and perspectives of municipal health officers in the Cordillera Administrative Region during the COVID-19 pandemic

Background@#Telemedicine has proven essential during COVID-19. However, concerns remain about the rural municipalities in the country such as those from the Cordillera Administrative Region (CAR), wherein perceived barriers by Municipal Health Officers (MHOs) include poor internet connectivity and inadequacy of the current telemedicine service.@*Objective@#This study aimed to assess the extent of Telemedicine use and perspectives in terms of perception, attitudes and perceived barriers among MHOs in CAR during COVID-19.@*Methods@#This is an analytical cross-sectional study that used a validated online questionnaire to 62 MHOs and DTTBs in CAR. Logistic regression analysis was employed to determine the effect of sociodemographic factors and physician perceptions and attitudes on the extent of Telemedicine use.@*Results@#Most MHOs use Telemedicine frequently in their practice for 0-1 year during COVID-19. There is no significant effect of sociodemographic factors to the extent of Telemedicine use except for IT expertise which had a negative influence on the extent of use [prevalence (p=0.011), frequency (p=0.013), length of use (p=0.044)]. Generally, MHOs agree that telemedicine is beneficial for them in performing consults with a positive effect on frequency (p=0.004) and length of use (p=0.009). There is positive attitude towards telemedicine, however, with no significant effect on extent of use (p=0.352, p=1.00, p=0.484). Compromised decision-making and network issues are the most prevalent perceived barriers that limit MHOs to practice Telemedicine. @*Conclusion and Recommendation@#This study showed that during COVID-19, there is good utilization of Telemedicine among MHOs in CAR. MHOs perceive Telemedicine as beneficial in their work and positive attitude remains. However, presence of barriers makes them apprehensive to fully incorporate it in their practice. Study results can contribute to policy-making on telemedicine as it is a key player in e- health to improve access to healthcare services in the attainment of the goal of Universal Healthcare.

Factors affecting medication adherence of hypertension and diabetes club members in the District Health Centers in the City of Baguio

Background@#Medication adherence is important to mitigate complications of NCDs. Hypertension and diabetes clubs were intended to make essential medications accessible to club members. Despite these efforts, patients avail treatment and management in acute care with noted complications. To address this problem, it is important to identify factors that affect patients’ adherence medication.@*Objectives@#This study aimed to determine the factors affecting adherence to medications of members enrolled in the Hypertension and Diabetes Club in the district health centers in the city of Baguio.@*Methods@#This is a cross-sectional study with a total of 374 respondents from the 16 different district health centers in the City of Baguio, obtained through random sampling. A validated questionnaire was utilized for the collection of data and was presented using percentage and frequency tables. A chi-square test was used to find the association of clinic-demographic data with respondents’ medication adherence.@*Results@#Hypertension and Diabetic Club members overall reported good adherence to medication. Majority of the respondents are female and are older than 61 years old while comorbidities show significant association with level of adherence. On the other hand, lack of finances, feeling that the drug is not effective, multiple medications, taking medications for many years, interference with meal plan, feeling the dose is too high, and complexity of drug regimen are noted to be associated factors for non-adherence.@*Conclusion@#Hypertension and Diabetes Club a community-based management in the City of Baguio shows a good impact on patients’ medication adherence. Comorbidities, chronicity, good family support as well as good physician-patient relationship can positively affect adherence to medications. On the other hand, factors affecting medications non-adherence are: complexity of medications, subjective report that medication is too high, interference to meal, having medications for many years and having multiple medications. Identifying factors affecting adherence and nonadherence are important to decrease further complications of the common NCDs.

Systematic Identification and Critical Appraisal of Pediatric COVID-19 Guidelines Applicable in India

Objective To systematically identify and critically appraise the methodological quality of pediatric guidelines applicable to management of COVID-19 in India. Methods Pediatric COVID-19 guidelines applicable to India, published until 30 April 2021, were identifed through a systematic search across ten databases. Each was critically appraised for methodological quality using the AGREE-II tool, by at least two appraisers. Median (interquartile range) of the total score and domain-wise scores were calculated, and compared for Indian vs. foreign guidelines, updated vs. original versions of guidelines, and those developed earlier vs. later in the pandemic. Results A total of 62 guidelines was identifed. Only 8 (12.9%) were published in India. The overall AGREE-II score ranged from 4.7% to 72.8%; with median (IQR) 37.9% (29.4, 48.6). This suggested overall low(er) methodological quality. The median (IQR) domain-wise scores were as follows: Scope and Purpose 66.7% (58.3, 83.3), Stakeholder Involvement 41.7% (30.6, 83.3), Rigor of Development 23.4% (14.8, 37.5), Clarity of Presentation 59.7% (50.0, 75.0), Applicability 27.1% (18.8, 33.3), and Editorial Independence 8.3% (0.0, 45.8). This suggested diversity in quality of diferent aspects of the guidelines, with very low quality in the critical domain of methodological rigor. There were no statistically signifcant diferences in the overall scores of Indian vs. foreign guidelines, updated versions vs. original versions, and those developed earlier vs. later in the pandemic. Conclusion The currently available pediatric COVID-19 guidelines have low methodological quality, adversely afecting their credibility, validity, and applicability. Urgent corrective strategies are presented for consideration.

Systematic Reviews and Meta-Analysis: A Guide for Beginners

Systematic reviews involve the application of scientific methods to reduce bias in review of literature. The key components of a systematic review are a well-defined research question, comprehensive literature search to identify all studies that potentially address the question, systematic assembly of the studies that answer the question, critical appraisal of the methodological quality of the included studies, data extraction and analysis (with and without statistics), and considerations towards applicability of the evidence generated in a systematic review. These key features can be remembered as six ‘A’; Ask, Access, Assimilate, Appraise, Analyze and Apply. Meta-analysis is a statistical tool that provides pooled estimates of effect from the data extracted from individual studies in the systematic review. The graphical output of meta-analysis is a forest plot which provides information on individual studies and the pooled effect. Systematic reviews of literature can be undertaken for all types of questions, and all types of study designs. This article highlights the key features of systematic reviews, and is designed to help readers understand and interpret them. It can also help to serve as a beginner’s guide for both users and producers of systematic reviews and to appreciate some of the methodological issues.

Efficacy and Safety of Pidotimod in Persistent Asthma: A Randomized Triple-Blinded Placebo-Controlled Trial

Objective: To study whether addition of pidotimod to inhaled corticosteroid (ICS) therapy enhances control in children with persistent asthma, as compared to ICS therapy alone. Design: Triple-blinded, randomized controlled trial. Setting: Allergy and Asthma Clinic, Department of Pediatrics, at a tertiary care hospital between May, 2018 and June, 2019. Patients: 79 children (5-12 years) with newly diagnosed persistent asthma as per Global Initiative for Asthma guidelines. Interventions: Children received 7 mL twice-a-day for 15 day, followed by 7 mL once-a-day for 45 days of either pidotimod (n=39) or placebo (n=40). In addition, both groups received inhaled budesonide via metered dose inhaler and spacer, throughout the study. Children were followed up every 4 weeks for a total of 12 weeks. At each follow-up visit, peak expiratory flow (PEF) and asthma symptom score and medicine adverse effects were recorded. Main outcome measures: Change in PEF at 12 weeks compared to baseline. Secondary outcomes were PEF at each follow-up visit, asthma symptom score at each visit, change in asthma symptom score at 12 weeks, and adverse event profile. Results: The median (IQR) change in PEF (from baseline to 12 weeks) was 13.0% (0.8%, 28.3%) in pidotimod group (n=35) vs 17.7% (4.3%, 35.2%) in placebo group (n=35) (P=0.69). All the secondary outcomes were also comparable between the two groups. There were no significant adverse effects observed. Conclusions: Addition of pidotimod for 8 weeks to standard ICS therapy did not enhance asthma control compared to placebo.

Hospital readmissions and emergency department re-presentation of COVID-19 patients: a systematic review / Reingreso de pacientes con COVID-19 a salas de hospitalización y servicios de urgencias: una revisión sistemática / Reinternação hospitalar e retorno ao pronto-socorro de pacientes com COVID-19: revisão sistemática

ABSTRACT Objective. To characterize the frequency, causes, and predictors of readmissions of COVID-19 patients after discharge from heath facilities or emergency departments, interventions used to reduce readmissions, and outcomes of COVID-19 patients discharged from such settings. Methods. We performed a systematic review for case series and observational studies published between January 2020 and April 2021 in PubMed, Embase, LILACS, and MedRxiv, reporting the frequency, causes, or risk factors for readmission of COVID-19 survivors/patients. We conducted a narrative synthesis and assessed the methodological quality using the JBI critical appraisal checklist. Results. We identified 44 studies including data from 10 countries. The overall 30-day median readmission rate was 7.1%. Readmissions varied with the length of follow-up, occurring <10.5%, <14.5%, <21.5%, and <30%, respectively, for 10, 30, 60, and 253 days following discharge. Among those followed up for 30 and 60 days, the median time from discharge to readmission was 3 days and 8-11 days, respectively. The significant risk factor associated with readmission was having shorter length of stay, and the important causes included respiratory or thromboembolic events and chronic illnesses. Emergency department re-presentation was >20% in four studies. Risk factors associated with mortality were male gender, advanced age, and comorbidities. Conclusions. Readmission of COVID-19 survivors is frequent, and post-discharge mortality is significant in specific populations. There is an urgent need to further examine underlying reasons for early readmission and to prevent additional readmissions and adverse outcomes in COVID-19 survivors.

RESUMEN Objetivo. Caracterizar la frecuencia, las causas y los factores predictores del reingreso de pacientes con COVID-19 tras haber recibido el alta de un centro de salud o un servicio de urgencias, las intervenciones utilizadas para reducir los reingresos y los resultados de los pacientes con COVID-19 dados de alta de dichos entornos. Métodos. Se realizó una revisión sistemática de estudios de serie de casos y estudios observacionales publicados entre enero del 2020 y abril del 2021 en PubMed, Embase, LILACS y MedRxiv en los cuales se informó sobre la frecuencia, las causas o los factores de riesgo relativos al reingreso de pacientes y sobrevivientes de COVID-19. Se realizó una síntesis narrativa y se evaluó la calidad metodológica utilizando la lista de verificación de evaluación crítica de JBI. Resultados. Se encontraron 44 estudios con datos de 10 países. La tasa media general de reingreso a los 30 días fue de 7,1%. Los reingresos variaron con la duración del seguimiento, y tuvieron lugar en <10,5%, <14,5%, <21,5% y <30%, respectivamente, a los 10, 30, 60 y 253 días después del alta. Entre los que recibieron seguimiento por 30 y 60 días, el tiempo medio entre el alta y la readmisión fue de 3 y de 8 a 11 días, respectivamente. El factor de riesgo significativo asociado al reingreso fue una estancia más corta, y entre las causas importantes se encontraron episodios respiratorios o tromboembólicos y enfermedades crónicas. El reingreso en el servicio de urgencias fue de >20% en cuatro estudios. Los factores de riesgo asociados con la mortalidad fueron sexo masculino, edad avanzada y comorbilidades. Conclusión. El reingreso de sobrevivientes de COVID-19 es frecuente, y la mortalidad después del alta es significativa en grupos poblacionales específicos. Existe una necesidad urgente de seguir examinando las razones subyacentes del reingreso temprano, así como de prevenir reingresos adicionales y resultados adversos en los sobrevivientes de COVID-19.

RESUMO Objetivo. Caracterizar a frequência, as causas e os preditores de reinternação de pacientes com COVID-19 após a alta do estabelecimento de saúde ou do pronto-socorro, intervenções usadas para reduzir reinternações e desfechos de pacientes com COVID-19 que receberam alta de tais instalações. Métodos. Revisão sistemática de séries de casos e estudos observacionais publicados entre janeiro de 2020 e abril de 2021, indexados nos bancos de dados PubMed, Embase, LILACS e MedRxiv, que relatassem a frequência, as causas ou os fatores de risco para a reinternação de sobreviventes da COVID-19/pacientes com COVID-19. Realizamos uma síntese narrativa das evidências e avaliamos a qualidade metodológica utilizando a checklist de avaliação crítica do Joanna Briggs Institute (JBI). Resultados. Foram identificados 44 estudos, incluindo dados de 10 países. O índice médio geral de reinternação em 30 dias foi de 7,1%. A frequência das reinternações variou com o tempo de acompanhamento, com <10,5%, <14,5%, <21,5% e <30%, respectivamente, ocorrendo nos primeiros 10, 30, 60 e 253 dias após a alta. Dentre aqueles seguidos por 30 e 60 dias, o tempo médio da alta até a reinternação foi de 3 dias e 8 a 11 dias, respectivamente. O único fator de risco significativamente associado à reinternação foi ter um tempo de permanência hospitalar mais curto, e as causas importantes incluíram eventos respiratórios ou tromboembólicos e doenças crônicas. Em quatro estudos, >20% dos pacientes retornaram ao pronto-socorro. Os fatores de risco associados à mortalidade foram sexo masculino, idade avançada e comorbidades. Conclusões. A reinternação hospitalar é frequente em sobreviventes da COVID-19 e a mortalidade pós-alta é significativa em populações específicas. Há uma necessidade urgente de examinar melhor as razões que levam à reinternação precoce e de evitar reinternações adicionais e desfechos adversos em sobreviventes da COVID-19.

Nephron-sparing surgery for bilateral sporadic giant angiomyolipomas

@#A 40-year-old female complains of right flank plain associated with progressive abdominal enlargement. She had stable vital signs and normal renal function. CT urogram revealed bilateral flank masses suggestive of bilateral giant angiomyolipomas. She was counseled on the various treatment options and opted to undergo open surgical excision. She underwent an open clamp-less partial nephrectomy with no intraoperative events. Operative time was 120 minutes and estimated blood loss was 250cc. She was discharged in good clinical condition on postoperative day 4. Final histopathological analysis revealed angiomyolipoma. Genetic testing was positive for mosaic variant of tuberous sclerosis. After a year of follow up, she remains stable and is maintained on everolimus. Open ischemia-free partial nephrectomy may be done safely for giant renal angiomyolipomas. Radical nephrectomy should be reserved for the last option because the presence of contralateral disease may also require surgical excision in the future.

Objective@#To describe a makeshift blue light filter for endoscopic visualization of a traumatic cerebrospinal fluid leak repair using intrathecal fluorescein and its application in one patient.@*Methods@# Study Design:Surgical Instrumentation Setting:Tertiary Government Training Hospital Patient:One @*Results@#Intra-operative endoscopic identification of fistulae sites was achieved using intrathecal injection of fluorescein that fluoresced using our makeshift blue light filter in a 43-year-old man who presented with a 3-month history of rhinorrhea due to skull base fractures along with multiple facial and upper extremity fractures he sustained after a fall from a standing height of 6 feet. He underwent transnasal endoscopic repair of cerebrospinal fluid fistulae in the planum sphenoidale, clivus and sellar floor. Post-operatively, there was complete resolution of rhinorrhea with no complications noted. @*Conclusion@#Our makeshift blue light filter made from readily available materials may be useful for endoscopic identification of CSF leaks using fluorescein in a low- to middle-income country setting like ours.

Antibacterial activity of Lactobacillus plantarum BS25, Pediococcus acidilactici S3 crude, and partially-purified cell-free supernatants against methicillinsusceptible and methicillin-resistant Staphylococcus aureus strains

Background@#The rising public health threat brought about by antibiotic resistance, such as of Staphylococcus aureus, opened doors of opportunities for natural products research to explore novel antimicrobial agents. @*Objective@#This study aimed to determine the antimicrobial activity of cell-free supernatants from Lactobacillus plantarum BS25 and Pediococcus acidilactici S3 against Staphylococcus aureus (ATCC# 25923) and methicillin-resistant S. aureus (ATCC# 33591). @*Methodology@#Cell-free supernatants (CFS) of Lactobacillus plantarum BS25 and Pediococcus acidilactici S3, isolated from fermented rice-fish mixture balao-balao and fermented spicy sausage longganisa, respectively, were tested against methicillin-susceptible (MSSA, ATCC 25923) and methicillin-resistant (MRSA, ATCC 33591) Staphylococcus aureus strains for antibacterial activity using the resazurin assay. @*Results@#Both BS25 and S3 CFS showed high activities against MSSA and partial inhibition against MRSA. Proteinaceous components of the CFS were extracted using ammonium sulfate precipitation with BS25 and S3 exhibited low activities against MSSA but partial inhibition was observed against MRSA. Other small molecules were extracted from the CFS through liquid-liquid extraction using ethyl acetate and tested in 100, 250, 500, 750, and 1000 ppm concentrations. The 1000-ppm concentrations of the BS25 and S3 ethyl acetate extracts achieved the highest antibacterial activity against MSSA and MRSA. @*Conclusion@#This study showed that the crude cell-free supernatants, ammonium sulfate precipitates, and ethyl acetate extracts of BS25 and S3 CFS exhibited potential in inhibiting Gram-positive MSSA and MRSA. However, the partially-purified samples require relatively high concentrations in order to produce significant inhibition activities and therefore require further purification.

Methods for Caries Prevention in Children Reported by Dentists from a Brazilian Community

ABSTRACT Objective: To describe the dental practice patterns related to caries prevention in children aged 6-18 years and associated factors. Material and Methods: Dentists (n=162) from Araraquara, Brazil, completed two paper questionnaires: (1) one about characteristics of their practice and their patient population; and (2) a translated version of the "Assessment of Caries Diagnosis and Caries Treatment" Questionnaire from the National Dental Practice-Based Research Network. Regression analyses were used for data analysis (p<0.05). Results: Dentists reported using in-office fluoride (IOF) and dental sealants (DS) in 74.2% and 45.1% of their pediatric patients, respectively. Regression analysis showed that female dentists (p=0.035 for DS; p=0.044 for IOF; p=0.011 for non-prescription fluoride rinse), those with advanced degrees (p=0.032 for prescription of fluoride), those who graduated from a private dental school (p=0.018 for chlorhexidine rinse), those who provided caries prevention regimens (p<0.001 for DS; p=0.004 for IOF; p=0.013 for non-prescription fluoride rinse), those with a greater percentage of patients interested in a caries prevention regimen (p=0.007 for non-prescription fluoride rinse), those working in a private practice model (p=0.047 for prescription of fluoride) were more likely to recommend some type of preventive methods to their pediatric patients. Conclusion: Dentists reported recommending IOF to most of their pediatric patients. Certain dentists', practices', and patients' characteristics were associated to some caries prevention regimens recommended by dentists.

Neuroactive venom compounds obtained from Phlogiellus bundokalbo as potential leads for neurodegenerative diseases: insights on their acetylcholinesterase and beta-secretase inhibitory activities in vitro

Spider venom is a rich cocktail of neuroactive compounds designed to prey capture and defense against predators that act on neuronal membrane proteins, in particular, acetylcholinesterases (AChE) that regulate synaptic transmission through acetylcholine (ACh) hydrolysis - an excitatory neurotransmitter - and beta-secretases (BACE) that primarily cleave amyloid precursor proteins (APP), which are, in turn, relevant in the structural integrity of neurons. The present study provides preliminary evidence on the therapeutic potential of Phlogiellus bundokalbo venom against neurodegenerative diseases. Methods Spider venom was extracted by electrostimulation and fractionated by reverse-phase high-performance liquid chromatography (RP-HPLC) and characterized by matrix-assisted laser desorption ionization-time flight mass spectrometry (MALDI-TOF-MS). Neuroactivity of the whole venom was observed by a neurobehavioral response from Terebrio molitor larvae in vivo and fractions were screened for their inhibitory activities against AChE and BACE in vitro. Results The whole venom from P. bundokalbo demonstrated neuroactivity by inducing excitatory movements from T. molitor for 15 min. Sixteen fractions collected produced diverse mass fragments from MALDI-TOF-MS ranging from 900-4500 Da. Eleven of sixteen fractions demonstrated AChE inhibitory activities with 14.34% (± 2.60e-4) to 62.05% (± 6.40e-5) compared with donepezil which has 86.34% (± 3.90e-5) inhibition (p > 0.05), while none of the fractions were observed to exhibit BACE inhibition. Furthermore, three potent fractions against AChE, F1, F3, and F16 displayed competitive and uncompetitive inhibitions compared to donepezil as the positive control. Conclusion The venom of P. bundokalbo contains compounds that demonstrate neuroactivity and anti-AChE activities in vitro, which could comprise possible therapeutic leads for the development of cholinergic compounds against neurological diseases.(AU)

Altered cisplatin pharmacokinetics during nonalcoholic steatohepatitis contributes to reduced nephrotoxicity

Disease-mediated alterations to drug disposition constitute a significant source of adverse drug reactions. Cisplatin (CDDP) elicits nephrotoxicity due to exposure in proximal tubule cells during renal secretion. Alterations to renal drug transporter expression have been discovered during nonalcoholic steatohepatitis (NASH), however, associated changes to substrate toxicity is unknown. To test this, a methionine- and choline-deficient diet-induced rat model was used to evaluate NASH-associated changes to CDDP pharmacokinetics, transporter expression, and toxicity. NASH rats administered CDDP (6 mg/kg, i.p.) displayed 20% less nephrotoxicity than healthy rats. Likewise, CDDP renal clearance decreased in NASH rats from 7.39 to 3.83 mL/min, renal secretion decreased from 6.23 to 2.80 mL/min, and renal CDDP accumulation decreased by 15%, relative to healthy rats. Renal copper transporter-1 expression decreased, and organic cation transporter-2 and ATPase copper transporting protein-7b increased slightly, reducing CDDP secretion. Hepatic CDDP accumulation increased 250% in NASH rats relative to healthy rats. Hepatic organic cation transporter-1 induction and multidrug and toxin extrusion protein-1 and multidrug resistance-associated protein-4 reduction may contribute to hepatic CDDP sequestration in NASH rats, although no drug-related toxicity was observed. These data provide a link between NASH-induced hepatic and renal transporter expression changes and CDDP renal clearance, which may alter nephrotoxicity.

Does Normal Saline Have Clinical Effects in Infants with Bronchiolitis?

The objective of this systematic review and meta-analysis was to measure the short-term association of nebulizednormal saline with physiologic measures of respiratory status in children having bronchiolitis by comparingnebulized normal saline with the use of other placebos. Randomized clinical trials comparing children 2 years oryounger with bronchiolitis who were treated with nebulized normal saline were included. Studies enrolling atreatment group receiving an alternative placebo were included for comparison of normal saline with otherplacebos. Pooled estimates of the association with respiratory scores, respiratory rates, and oxygen saturationwithin 60 minutes of treatment were generated for nebulized NS vs another placebo and for change before and afterreceiving nebulized normal saline. A total of 29 studies including 1583 patients were included. Standardized meandifferences in respiratory scores for nebulized normal saline vs other placebo (3 studies) favored nebulized NS by –0.9 points (95% CI, –1.2 to –0.6 points) at 60 minutes after treatment (P<0.001). The standardized mean differencein respiratory score (25 studies) after nebulized NS was –0.7 (95% CI, –0.7 to –0.6; I2 = 62%). The weighted meandifference in respiratory scores using a consistent scale (13 studies) after nebulized NS was –1.6 points (95% CI, –1.9 to –1.3 points; I2 = 72%). The weighted mean difference in respiratory rate (17 studies) after nebulized NS was –5.5 breaths per minute (95%CI, –6.3 to –4.6 breaths per minute; I2 = 24%). The weighted mean difference in oxygensaturation (23 studies) after nebulized NS was –0.4% (95% CI, –0.6%to –0.2%; I2 = 79%). The authors concludedthat nebulized normal saline may be an active treatment for acute viral bronchiolitis and recommended that furtherevaluation should occur to establish whether it is a true placebo.
