The 5P stairs model: A guide to school visits

@#A school visit is defined as a process wherein a person with specific expertise and preparation goes to a school for a limited period of time and gathers information on how a student is functioning within that setting. Aside from giving thorough guidelines for conducting a school visit, the 5P Stairs Model presents five (5) steps that can establish a better working relationship among the stakeholders, motivated by one main goal: to support the child’s performance within the school setting. The model presents the 5P’s: a) Preparation, which focuses on the delivery of consent and request letters upon identifying the need for a visit; b) Pre-observation for the briefing, focusing on the collaboration between the therapist and the teacher on how the process could mutually benefit them and the child; c) Observation Proper which includes taking note of relevant observations using a checklist; d) Post-observation for debriefing is where feedback to the teacher takes place; and e) Planning and Partnership which includes providing recommendations and necessary interventions, through the continuous collaboration among the therapist, family, and school. Furthermore, supplemental materials such as template letters, a questionnaire, and an observation form were developed to facilitate the aforementioned steps. The framework’s processes and steps serve as a guide and are not meant to be prescriptive. A pilot study on the 5P Stairs Model’s processes and supplemental files is recommended to help establish its usefulness, validity, and effectiveness.

Visual outcomes and complications of intraocular lens placement in the absence of capsular support in a Philippine Tertiary Hospital

Background@#Surgical correction of aphakia without capsular support continues to be a challenge. Improvements in the technology of cataract surgery have provided advancements in techniques in surgical management of aphakia. Locally, we have limited data on the outcomes of the different intraocular lenses used in aphakia.@*Objective@#This study aimed to determine visual outcomes and complications associated with different techniques of intraocular lens implantation in the absence of capsular support.@*Methods@#We reviewed the medical charts of 207 patients who underwent intraocular lens implantation without capsular support. Excluded were patients with incomplete follow up, pediatric patients, and lost records. Best corrected visual acuity at day 1, 1st month, 3rd month and 6th month postoperatively, and the complications were noted.@*Results@#Mean age was 60 and 51% (n=105) were females. The mean follow-up time was 9.33 ± 0.71 months. Loss of capsular support was most frequently caused by intraoperative complication (n=146, 70%) and trauma. Retropupillary fixation iris claw intraocular lens was frequently used (n=93, 44.9%). Across all patients, visual acuities showed excellent outcomes with 20/50 or better. Across IOL types, the most frequent postoperative complication was increase in IOP. Statistically significant results were set at P <0.05. @*Conclusion@#There is a notable preference towards iris claw retropupillary lenses through time. Iris claw lenses showed the shortest operative time. All intraocular lenses used in aphakia showed comparably good postoperative visual acuities, except for the superior visual acuity trend seen among retropupillary iris claw and anterior chamber IOL groups. Complications included elevated intraocular pressures, corneal edema, and pigment dispersion.

Convalescent plasma as adjunctive therapy for hospitalized patients with COVID-19:The Co-CLARITY Trial

Background and Objective@#Convalescent plasma therapy (CPT) may reduce the risk of disease progression among patients with COVID-19. This study was undertaken to evaluate the efficacy and safety of CPT in preventing ICU admission among hospitalized COVID-19 patients.@*Methods@#In this open-label randomized controlled trial, we randomly assigned hospitalized adult patients with COVID-19 in a 1:1 ratio to receive convalescent plasma as an adjunct to standard of care or standard of care alone. The primary endpoint was ICU admission within first 28 days of enrolment. Primary safety endpoints include rapid deterioration of respiratory or clinical status within four hours of convalescent plasma transfusion and cumulative incidence of serious adverse events during the study period including transfusion-related acute lung injury (TRALI), transfusion-associated circulatory overload (TACO), severe allergic reactions, and transfusion-related infections.@*Results@#A total of 22 patients were assigned to receive convalescent plasma as an adjunct to standard of care and 22 to receive standard of care alone. The median time from onset of COVID-19 symptoms to study enrolment was eight days (IQR, 4 to 10). Two patients (9.1%) in the CPT group and one patient (4.5%) in the control group were admitted to the ICU. The primary outcome measure, ICU admission, was not different between the two groups (q-value >0.9). No patient who received convalescent plasma had rapid deterioration of respiratory/clinical status within four hours of transfusion and none developed TRALI, TACO, anaphylaxis, severe allergic reactions, or transfusion-related infections. There was also no significant difference in the secondary outcomes of 28-day mortality (two patients in the CPT group and none in the control group, q-value >0.90), dialysis-free days, vasopressor-free days, and ICU-free days.@*Conclusions@#Among hospitalized COVID-19 patients, no significant differences were observed in the need for ICU admission between patients given CPT as adjunct to standard of care and those who received standard of care alone. Interpretation is limited by early termination of the trial which may have been underpowered to detect a clinically important difference.

R-CHOP and consolidation radiotherapy for limited-stage and low-IPI high-grade b-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements: A single-center case series and review of literature

@#High-Grade B-Cell Lymphoma (HGBCL) with gene rearrangements in MYC and BCL2 and/or BCL6 is an aggressive malignancy usually presenting in advanced stages. Current recommendations suggest the use of regimens more intensive than R-CHOP (rituximab, cyclophosphamide, vincristine, doxorubicin, prednisone), which are based on retrospective studies and single-arm prospective trials that included patients who are mostly in the advanced stage, and did not receive consolidation radiotherapy. The optimal approach and treatment of HGBCL, whether limited-stage (LS) or advanced-stage, remains to be determined. Here we describe the promising outcomes of three patients with LS and low IPI HGBCL with the use of R-CHOP as induction chemotherapy regimen, which was followed by consolidation radiotherapy. Three women, 54-, 60-, and 64-years of age diagnosed to have HGBCL with MYC, and BCL2 and/or BCL6 rearrangements, with Ann Arbor stages I-IIE were included in this case series. All three patients had complete metabolic response to 6 cycles of R-CHOP and was subsequently treated with consolidation involved site radiotherapy (ISRT; total dose 30-36 Gy). Chemotherapy and radiotherapy were tolerated very well. All patients remain to be in remission, with the longest being at 23 months. Outcomes of patients with HGBCL generally remain to be poor, but this may not be the case for patients with limited-stage disease and favorable clinicopathologic risk profile. Nevertheless, the treatment of HGBCL is currently evolving and more studies are needed to determine the ideal approach and preferred chemotherapy regimen. Also, more studies are needed to elucidate the potential role of consolidation radiotherapy in patients with limited-stage HGBCL to improve survival outcomes. Findings of this case series suggest that patients with LS HGBCL may still derive benefit from R-CHOP followed by consolidation ISRT, but prospective trials are needed to confirm this.

Manual versus markerless (Image-guided system) toric intraocular lens implantation outcomes for astigmatic correction in cataract surgeries

Objective@#Toric intraocular lens implantation has been used to correct corneal astigmatism during cataract surgery. The study aimed to compare the visual outcomes between manual vs markerless toric intraocular lens implantation in astigmatic correction.@*Methods@#The medical records of patients at American Eye Center who underwent phacoemulsification by multiple surgeons with insertion of monofocal or multifocal toric lenses via manual marking and markerless method from 2010-2019 were reviewed.@*Results@#A total of 70 patients were included in the study. Results showed no significant difference in the following characteristics between manual and markerless method at one month and two months post-cataract surgery: uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected near vision acuity (UNVA), corrected near vision acuity (CNVA), refraction spherical equivalent. The UDVA, CDVA, UNVA, CNVA and astigmatism had significantly lower median/mean-rank at one and two months postoperatively compared to preoperative values.@*Conclusion@#In conclusion, our findings indicated that both manual-based and markerless systems effectively facilitated accurate placement of the toric IOL on the desired axis. Notably, there was no significant difference observed between the two methods. Both systems are straightforward to execute. In low-resource settings like the Philippines, the manual marking method can be employed when markerless guidance equipment is unavailable.

Accessibility of soil-transmitted Helminthiasis control strategies in selected indigenous people communities in the Philippines

Background@#Indigenous peoples (IPs) remain vulnerable to soil-transmitted helminthiasis (STH) due to limited access to sanitary toilets, clean water, quality health education, and services. The World Health Organization recommends periodic mass drug administration (MDA) of anthelminthics, health education, and improvements in water, sanitation, and hygiene (WASH) as control strategies to reduce morbidities caused by STH in target populations such as schoolage children (SAC). This paper complements the published results of the parasitological survey (prevalence and intensity of STH) conducted in selected Aeta and Ata-Manobo communities. @*Objectives@#This study aimed to describe the accessibility of STH control strategies to respond to the needs of SAC in IP communities in Pampanga and Davao del Norte, the Philippines. It likewise intended to describe access of these IP communities to STH control strategies. @*Methods@#Data on accessibility of and access to STH control strategies were collected using key informant interviews (KIIs) and focus group discussions (FGDs). Eleven officials and workers from the departments of health and education, local government units, and two IP leaders were interviewed on the existing STH burden in SAC, implementation of STH control strategies, particularly of MDA, health education campaigns, and improvements in WASH including good practices and challenges in program implementation. Three FGDs with parents, elementary school teachers of IP schools, and rural health midwives were conducted separately. Guide questions focused on accessibility of and access to STH prevention and control strategies for SAC in IP communities. Informed consent to conduct and record KIIs and FGDs were obtained from participants prior to participation. Analysis of a multi-disciplinary team was based on the accessibility framework for IPs accessing indigenous primary health care services by Davy et al. (2016). @*Results@#The characteristics of the STH control strategies and the target populations are interrelated factors that influence accessibility. Challenges in the availability of the MDA program, particularly, inadequate staffing, drug shortages, and delays in delivery affect accessibility of and access to the free STH control strategies. Perceived harm, adverse events, stigma, beliefs, and practices likewise affect access. Lack of information on the similarity of treatment through community- and schoolbased MDA programs also affected engagement of SAC. IP communities are special settings where geographic isolation, peace and order situation as well as water supply need to be considered to help ensure access to STH control strategies, high MDA coverage, and improvements in WASH leading to desired outcomes. @*Conclusions@#Considering the context of IP communities and addressing the challenges in the accessibility of and access to STH control strategies are necessary to ensure successful implementation of an integrated approach in STH prevention and control strategies. Challenges in the accessibility of STH control strategies are inadequate staffing, poor inventory, and delays in the delivery of drugs, as well as poor sanitation and hygiene. Access of SAC is likewise affected by misconceptions on safety and efficacy of anthelminthics, including stigma and cultural practices. The similarity of the MDA programs based in school or community need to be disseminated.

Understanding adoption of Electronic Medical Records (EMRs) during a health emergency: An analysis of EMR usage logs from rural health facilities in the Philippines

Background and Objective@#The adoption of electronic medical records (EMRs) in the Philippines has been initiated and adjusted since the last decade through the Philippine eHealth Agenda framework. EMRs are known to improve clinical management and have been widely adopted in advanced economies. However, empirical research on EMR implementation remains limited. This study aims to determine how public primary health care facilities in the country interacted with EMRs before and during the COVID-19 pandemic to understand EMR adoption.@*Methods@#More than 270,000 records generated from EMR usage logs in six rural primary health facilities in Western Visayas were analyzed. Average time of EMR use during work hours was estimated and compared before and during the pandemic. EMR adoption based on specific EMR features used was also determined. @*Results@#In 2020, EMR use ranged from less than one hour to more than eight hours in selected rural health units (RHUs). There was a statistical increase and decrease in use of features during the pandemic. Some EMR users had efficient use indicated by complete adoption of EMR features although such features were not as frequently used as those pertaining to basic adoption. @*Conclusion@#This study demonstrates that for EMR use in rural settings, progressive use from basic to complete may vary among users. Public health emergencies such as a pandemic may also affect EMR use. Future research directions should explore other mechanisms which affect user behavior and encourage full adoption of technology such as use of games or non-monetary incentives.

Intravenous tocilizumab versus standard of care in the treatment of severe and critical COVID-19-related pneumonia: A single center, double-blind, placebo controlled, phase 3 trial

Background@#Severe and critical COVID-19 disease is characterized by hyperinflammation involving pro-inflammatory cytokines, particularly IL-6. Tocilizumab is a monoclonal antibody that blocks IL-6 receptors. @*Objectives@#This study evaluated the efficacy of tocilizumab in Filipino patients with severe to critical COVID-19 disease. @*Methods@#This phase 3 randomized double-blind trial, included patients hospitalized for severe or critical COVID-19 in a 1:1 ratio to receive either tocilizumab plus local standard of care or placebo plus standard of care. Patients were eligible for a repeat IV infusion within 24-48 hours if they deteriorated or did not improve. Treatment success or clinical improvement was defined as at least two categories of improvement from baseline in the WHO 7-point Ordinal Scale of patient status, in an intention-to-treat manner. @*Results@#Forty-nine (49) patients were randomized in the tocilizumab arm and 49 in the placebo arm. There was no significant difference in age, comorbidities, COVID-19 severity, need for mechanical ventilation, presence of acute respiratory distress syndrome, or biomarker levels between groups. Use of adjunctive therapy was similar between groups, with corticosteroid used in 91.8% in tocilizumab group and 81.6% in the placebo group, while remdesivir was used in 98% of participants in both groups. There was no significant difference between groups in terms of treatment success in both the intention-to-treat analysis (relative risk=1.05, 95% CI: 0.85-1.30) and per-protocol analysis (relative risk=0.98, 95% CI: 0.80 to 1.21). There was no significant difference in time to improvement of at least two categories relative to baseline on the 7-point Ordinal Scale of clinical status. @*Conclusion@#The use of tocilizumab on top of standard of care in the management of patients with severe to critical COVID-19 did not result in significant improvement as defined by the WHO 7-point Ordinal Scale of patient status, nor in significant improvement in incidence of mechanical ventilation, incidence of ICU admission, length of ICU stay, and mortality rate.

Effect of Garcinia binucao crude leaf extract supplementation on lifespan of Drosophila melanogaster chronically exposed to alcohol

Background@#Consumption and abuse of alcohol remains a significant cause of concern worldwide. Furthermore, there is evidence of the association between chronic alcohol use and reduced life expectancy. @*Objectives@#To study the effects of Garcinia binucao extract (GBE) supplementation on lifespan of Drosophila melanogaster, in the presence or absence of chronic alcohol exposure.@*Methods@#D. melanogaster was mass cultured and given GBE supplementation in high (1 mg/mL) and low (200 µg/mL) sublethal doses. D. melanogaster flies were divided into groups - with and without chronic alcohol exposure, and their respective lifespans were monitored. @*Results@#In D. melanogaster without alcohol exposure, mean lifespan was highest in the control flies (38.15 days), followed by high-dose GBE (34.42 days), low-dose GBE (33.24 days), and DMSO (22.29 days). In D. melanogaster chronically exposed to alcohol, the longest mean lifespan was observed in flies treated with high-dose GBE (33.80 days), followed by low-dose GBE (33.63 days), the DMSO group (30.30), and the control group (29.65 days), but the differences were not statistically significant. Comparing groups with and without chronic alcohol exposure, the mean lifespan of the control group chronically exposed to alcohol significantly decreased by 9.51 days (p < 0.05). In GBE treatment groups, mean lifespan significantly decreased by 0.82 days in high-dose set-up (p < 0.05), and significantly increased by 0.39 days in the low-dose set-up (p < 0.05) upon chronic alcohol exposure. @*Conclusion@#Garcinia binucao extract supplementation ameliorated the observed reduction in lifespan of Drosophila melanogaster chronically exposed to alcohol.

Effects of the COVID-19 pandemic on the implementation of NCD Care at the Primary Care Level in the Philippines: A qualitative inquiry

Background and Objective@#The focusing of resources to COVID-19 response hampered and disadvantaged primary care services including that for Non-Communicable Diseases (NCDs), compromising continuity of care and hence, patients’ disease status. However, studies from low- and middle-income countries (LMICs) remain sparse; therefore, evidence generation on how the pandemic impacted the provision of these primary care services in LMICs will help further understand how policies can be reframed, and programs be made more efficient and effective despite similar crises. To bridge this gap, the study investigated how the pandemic affected the implementation of NCD care at the primary care level in the Philippines.@*Methods@#Thirty-one online focus group discussions via Zoom Meetings were conducted among 113 consenting physicians, nurses, midwives, and community health workers from various facilities — community health centers and stations, free-standing clinics, infirmaries, and level 1 hospitals — located within two provinces in the Philippines. All interviews were video-recorded upon participants’ consent and transcribed verbatim. Inductive thematic analysis was employed through NViVo 12® to generate themes, identify categories, and describe codes. @*Results@#The impact of COVID-19 on NCD care at the primary care level revolved around heightened impediments to service delivery, alongside worsening of pre-existing challenges experienced by the healthcare workforce; subsequently compelling the public to resort to unhealthy practices. These detriments to the primary healthcare system involved resource constraints, discontinued programs, referral difficulties, infection, overburden among workers, and interrupted training activities. Citizens were also observed to adopt poor healthcare seeking behavior, thereby discontinuing treatment regimen. @*Conclusion@#Healthcare workers asserted that disadvantages caused by the pandemic in their NCD services at the primary care level possibly threaten patients’ health status. Besides the necessity to address such detriments, this also emphasizes the need for quantitative studies that will aid in drawing inferences and evaluating the effect of health crises like the pandemic on such services to bridge gaps in improving quality of care.

Effect of Terpenes on the enhancement of skin permeation of lipophilic drugs: A systematic review

Objectives@#The stratum corneum (SC) remains an obstacle to the passage of drugs applied topically. Several investigations have focused on enhancing the penetration of drugs through the SC by integrating permeation enhancers (PE) into the drug formulation. Terpenes are among the PE utilized in formulations and are categorized by the regulatory bodies as generally recognized as safe (GRAS). This study aimed to comparatively analyze the skin permeation enhancing effect of terpenes on lipophilic drugs. @*Methods@#The present study reviewed the effects of terpenes on the permeation of lipophilic small-molecule drugs through the skin using original research published between 2000 - 2022 retrieved from PubMed®. The search phrase used was (lipophilic drug) AND (terpene) AND (permeation enhancer). @*Results@#Terpenes increase the percutaneous permeation of lipophilic small molecule drugs by 1.06 – 256.80-fold. Linear correlation analysis of terpenes’ cLog P with enhancement ratio (ER) revealed moderate and strong positive correlations in pig skin (r = 0.21) and mouse skin (r = 0.27), and rat skin (r = 0.41) and human skin (r = 0.67), respectively. Drug cLog P is a poor (r = -0.06) predictor of permeation enhancement. Terpenes with cLog P higher than 2.40 had ER greater than 10. Higher ERs (>30) were recorded for nerolidol, carvacrol, borneol, terpineol, limonene, menthone, pulegone, and menthol among the terpene-chemical penetration enhancers. @*Conclusion@#cLog P of terpene-based chemical permeation enhancers (CPE) is strongly correlated with ER of lipophilic drugs across human skin. Non-polar groups in terpenes and hydrogen bond interactions by terpenes with SC lipid enhance cutaneous drug penetration of lipophilic drugs.

Determination of liver function tests and liver ultrasonographic findings in patients with leptospirosis in a Tertiary Hospital

Introduction@#ILeptospirosis is an important zoonotic disease commonly found in tropical or sub-tropical countries. The most severe form is Weil's syndrome which presents with jaundice, renal failure, and bleeding diatheses. Although jaundice occurs in 38% of patients with leptospirosis, no studies in Asia have focused on the liver biochemical profile of these patients. Characterization of liver biochemical profile and ultrasonographic findings may shed more light on the disease process. Identification of liver biochemical parameters that portend a poor prognosis may also allow for early aggressive intervention. @*Objective@#To describe the liver biochemical profile and liver ultrasonographic findings in adult patients with laboratoryconfirmed leptospirosis, admitted at a tertiary hospital in Manila, Philippines. The association of clinical and laboratory features with clinical outcomes (i.e., severe liver injury, Weil’s syndrome, and mortality) was also investigated. @*Methods@#This retrospective cross-sectional study reviewed all available cases of adult patients with laboratoryconfirmed leptospirosis admitted in the Philippine General Hospital from January 2009 to August 2018. The clinical features, liver biochemical profiles, and ultrasound findings were recorded and analyzed. Comparison between the means of each group based on clinical outcome (i.e., mortality, Weil’s syndrome) was done via Students’ t-test for continuous variables, and calculation of the Odds Ratio for categorical variables.@*Results@#Total and direct bilirubin levels were elevated in patients with leptospirosis compared to serum aminotransferases and alkaline phosphatase levels which were only mildly elevated. Abdominal ultrasound showed typically un-enlarged livers with normal parenchymal echogenicity, normal spleens, and non-dilated biliary trees. Dyspnea was associated with an increased odds for mortality. Although jaundice was present in 39.5% of patients and significantly associated with severe liver injury, this was not associated with mortality. Liver biochemical test values did not differ among patients who expired and those who survived to discharge. The presence of myalgia and abdominal pain increased the odds for Weil's syndrome.@*Conclusion@#To date, no local studies have fully described the liver biochemical profile of patients with leptospirosis. Our findings are compatible with previous studies showing that leptospirosis typically presents with predominantly elevated direct bilirubin from cholestasis and systemic infection. Contrary to previous literature, however, our study found no association between jaundice and mortality.

Treatment options for hemodialysis-related central vein occlusive disease: Case series and review of literature

@#Central venous occlusive disease is commonly seen in patients undergoing hemodialysis and can threaten the viability of the arteriovenous access. Majority of cases are related to central venous catheter placement. This paper reports on three patients on chronic hemodialysis who presented with signs and symptoms of upper extremity venous hypertension and underwent three different therapeutic modalities, all with successful relief of symptoms. A review of the existing literature on past and current treatment options is done.

Economic evaluation of oral ivermectin, alone or in combination with permethrin, versus permethrin, in the treatment of classic scabies in the Philippine Setting

Background and Objective@#Oral ivermectin is recommended as an alternative to topical permethrin in Japanese, European, and CDC-STI guidelines for treating classic scabies. The combination of oral ivermectin and topical permethrin is also used in some settings. Partial economic evaluations conducted in India and Egypt have conflicting results, and no cost-effectiveness analysis in the Philippines has compared ivermectin-based regimens to permethrin for scabies treatment. We aimed to determine the cost-effectiveness of oral ivermectin, alone or in combination with permethrin, compared to permethrin, in the treatment of Filipino adult patients with classic scabies.@*Methods@#We used a decision tree model to estimate the cost-effectiveness of two regimens, oral ivermectin alone or in combination with permethrin, compared with permethrin to treat adults and children aged five years and older with classic scabies in the outpatient setting from the household perspective in the Philippines. We estimated total costs and disability-adjusted life years (DALYs) over a one-month follow-up. Input parameters were obtained from secondary data, such as effect estimates for probabilities of clinical outcomes from a network meta-analysis, DALYs from the Global Burden of Disease 2019, and prevailing market cost in the Philippines (DPRI 2022 with recommended markup by DOH, and leading drugstores) as of August 2022. We computed for incremental cost-effectiveness ratio (ICER) and net monetary benefit (NMB) to determine which of the interventions are cost-effective. Univariate and probabilistic sensitivity analyses, and scenario analyses were conducted to assess the impact of parameter and structural uncertainty.@*Results@#Ivermectin-based regimens are suggested to be likely cost-saving compared to permethrin in the Philippine outpatient setting. Base case analysis showed that oral ivermectin had higher cost-savings (change in cost, -1,039.31; change in DALYS, 0.00027), while combination oral ivermectin/permethrin had higher DALYs averted (change in cost, PhP -1,019.78; change in DALYs, 0.00045), compared to permethrin. Combination oral ivermectin/permethrin (56%) was the most cost-effective, followed by oral ivermectin (44%) compared to permethrin (0%) through probabilistic sensitivity analysis. Estimates for ivermectin were sensitive to risk of cure for ivermectin vs permethrin using 1-way deterministic sensitivity analysis. Oral ivermectin was favored over combination oral ivermectin/permethrin at all thresholds based on the cost-effectiveness acceptability curve.@*Conclusion@#Both ivermectin-based regimens seem to be cost-saving compared to permethrin in the treatment of classic scabies in the Philippine outpatient setting. Clinicians may consider oral ivermectin, alone or in combination with permethrin as an alternative first-line or second-line treatment depending on patient preference, adverse event risk profile, availability, and economic capacity. This needs to be confirmed using primary data from Filipino patients to enhance the robustness of the findings and support evidence-based local decision-making in different settings. Less uncertainty in modelled parameters can give greater confidence in the results, which can be adopted for budget impact analysis and allow more rational resource allocation. Value of information analysis can be done to determine whether the expense of future RCTs or surveys in Filipinos to collect primary data is worth it. The cost of reducing uncertainty, if deemed worth the cost of further studies, may facilitate population-level decision-making and budget planning. Findings may further inform practice guideline development, coverage decisions, and national control program planning by providing the most cost-effective scabies intervention.

Toxoplasmosis outbreak in São Paulo, Brazil: Epidemiology and visual outcome

ABSTRACT Purpose: To describe a 2019 acute toxoplasmosis outbreak in the city of São Paulo, Brazil, and to evaluate the laboratory serological profile for toxoplasmosis for three consecutive years. The ophthalmological manifestations of the patients involved in the outbreak were also studied. Methods: A cross-sectional descriptive study of a toxoplasmosis outbreak in São Paulo, Brazil, between February and May 2019. Epidemiological data were described, as were the observed ocular manifestations. As part of this study the number of patients with positive IgM toxoplasmosis serology was obtained from a large laboratory network (DASA) for three consecutive years, including the year of the outbreak (2018, 2019, 2020). Results: Eighty-three individuals were identified in the outbreak and two clusters were studied. The clinical picture of at least 77% of the patients, the epidemiological analysis, and the short incubation period (5-8 days) suggested contamination by oocysts. Serological laboratory data analysis revealed an increase of positive toxoplasmosis IgM in 2019 of 73% compared to the previous year. Ophthalmological examination revealed that at least 4.8% of the patients developed toxoplasmic retinochoroiditis, none of whom had been treated during the acute systemic disease. Conclusion: Our findings indicate vegetable contamination as the possible source of this outbreak, a high prevalence of toxoplasmosis in São Paulo during the outbreak period, and a drop in the number of tests during the COVID-19 pandemic. Retinochoroiditis was observed in at least 4.8% of the cases. We confirm the need to implement effective means for the prevention, diagnosis, and treatment of the disease. This may involve raising awareness among the population of the importance of vegetable hygiene, and improved quality control of food and water.

Consensus from the Brazilian Academy of Neurology for the diagnosis, genetic counseling, and use of disease-modifying therapies in 5q spinal muscular atrophy / Consenso da Academia Brasileira de Neurologia para diagnóstico, aconselhamento genético e uso de terapias modificadoras na atrofia muscular espinhal 5q

Abstract Spinal muscular atrophy linked to chromosome 5 (SMA-5q) is an autosomal recessive genetic disease caused by mutations in the SMN1. SMA-5q is characterized by progressive degeneration of the spinal cord and bulbar motor neurons, causing severe motor and respiratory impairment with reduced survival, especially in its more severe clinical forms. In recent years, highly effective disease-modifying therapies have emerged, either acting by regulating the splicing of exon 7 of the SMN2 gene or adding a copy of the SMN1 gene through gene therapy, providing a drastic change in the natural history of the disease. In this way, developing therapeutic guides and expert consensus becomes essential to direct the use of these therapies in clinical practice. This consensus, prepared by Brazilian experts, aimed to review the main available disease-modifying therapies, critically analyze the results of clinical studies, and provide recommendations for their use in clinical practice for patients with SMA-5q. This consensus also addresses aspects related to diagnosis, genetic counseling, and follow-up of patients under drug treatment. Thus, this consensus provides valuable information regarding the current management of SMA-5q, helping therapeutic decisions in clinical practice and promoting additional gains in outcomes.

Resumo Atrofia muscular espinhal ligada ao cromossomo 5 (AME-5q) é uma doença genética de herança autossômica recessiva causada por mutações no gene SMN1. A AME-5q cursa com degeneração progressiva dos motoneurônios medulares e bulbares, acarretando grave comprometimento motor e respiratório com redução da sobrevida, especialmente nas suas formas clínicas mais graves. Nos últimos anos, terapias modificadoras da doença altamente eficazes, ou que atuam regulando o splicing do exon 7 do gene SMN2 ou adicionando uma cópia do gene SMN1 via terapia gênica, têm surgido, proporcionando uma mudança drástica na história natural da doença. Dessa forma, o desenvolvimento de guias terapêuticos e de consensos de especialistas torna-se importante no sentido de direcionar o uso dessas terapias na prática clínica. Este consenso, preparado por especialistas brasileiros, teve como objetivos revisar as principais terapias modificadoras de doença disponíveis, analisar criticamente os resultados dos estudos clínicos dessas terapias e prover recomendações para seu uso na prática clínica para pacientes com AME-5q. Aspectos relativos ao diagnóstico, aconselhamento genético e seguimento dos pacientes em uso das terapias também são abordados nesse consenso. Assim, esse consenso promove valiosas informações a respeito do manejo atual da AME-5q auxiliando decisões terapêuticas na prática clínica e promovendo ganhos adicionais nos desfechos finais.
