BACKGROUND

Pneumococcal vaccination has been widely used for the prevention of pneumococcal disease, with two types of vaccines available since 2009. With the World Health Organization (WHO) recommendation of incorporating pneumococcal conjugate vaccines (PCVs) in National Immunization Programs (NIPs) worldwide, a ten-valent PCV (PHiD-CV) was initially introduced in the Philippines in 2012. This, however, transitioned to the use of the 13-valent PCV (Prevnar) subsequent to the recommendation of the Formulary Executive Council in 2014.

This review aimed to present evidence on pneumococcal disease and vaccine inclusion in the Philippine NIP from 2005 - 2021.

This narrative review compiled articles on Pneumococcus from January 2005 to October 2021, sourcing literature from databases such as BIOSIS Preview, CAB Direct, Embase, Google Scholar, and others.

In the Philippines, there was a shift in prevalent serotypes of Streptococcus pneumoniae among children under five following the introduction of PCV13 in the National Immunization Program in 2014, with serotype 14 becoming the most common by 2018, and a significant reduction in isolates reported in 2020, where only serotypes 5, 19A, and 23F were identified among invasive strains. The immunogenicity results of a potential vaccine candidate should be factored into the overall evidence when conducting a reassessment of PCV.

As part of the decision making about the inclusion of the PCVs in the NIP of the Philippines, various factors such as local epidemiology, vaccine supply, cost, and programmatic characteristics must be careful weighed. Enhancing laboratory and surveillance capacity are essential to provide evidencebased decision-making in terms of existing serotype distribution and antimicrobial resistance (AMR) profile in the country. With the introduction of a new affordable formulation of a 10-valent PCV offering a comparable serotype coverage, the reassessment of choice of PCV with the consideration of all three formulations, namely PCV13, PHiD-CV, and SIIPL-PCV, may be warranted.

BACKGROUND

The World Health Organization (WHO) estimates that in 2015, approximately 325 million or 4.4% of the global population were living with chronic hepatitis B or hepatitis C infection. In the same year, around 1.34 million died from this disease.

This study aimed to estimate the burden of hepatitis B in the Philippines and to determine the costeffectiveness of possible interventions.

This study utilized the Center for Disease Analysis Foundation’s (CDAF’s) mathematical disease burden model of hepatitis B. Model inputs were collected using literature review, key informant interviews, expert panel interviews, and records review, and were validated through a series of round table discussions with experts.

Results show that in 2017, the prevalence of chronic hepatitis B infection in the Philippines was 9.7%, equivalent to 10 million infected individuals. Although the model projects a decreasing trend in chronic hepatitis B virus (HBV) infections, liver-related mortality and morbidity due to these viruses are expected to rise if the status quo is maintained. Results show that substantial increase in government subsidy for WHO elimination scenarios would be required to achieve cost-effective outcomes.

Hepatitis B remains a huge problem in the Philippines. The HBV modelling exercise reveal that it will be worthwhile and cost-effective to adhere to the WHO elimination targets. A substantial financial investment will be necessary to do so, specifically a significant scale up in the screening, diagnosis, treatment, and monitoring of patients with HBV. While this modelling exercise does not yield burden of disease as accurate as a prevalence survey, experts consulted in the round table discussions agreed with the modelling inputs.

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.

Background: The COVID-19 pandemic became a severe public health threat to the Philippines, overwhelming the health system and its healthcare workers. As infections spread globally, it became imperative to understand the infection prevention practices (e.g., face mask-wearing, handwashing, social distancing) to better understand the pandemic and its effects on the healthcare workforce. Objective: The study aims to describe the sociodemographic and medical profile and the COVID-19 infection prevention practices, and the correlation between both among employees of a medical center in the National Capital Region (NCR), Philippines, Methods: The analytic cross-sectional study utilized an online survey administered to employees of a medical center in NCR, Philippines. A total of 112 responses were analyzed. Descriptive statistics were used to analyze respondents’ sociodemographic and medical characteristics and summarize their COVID-19 infection prevention practices. Spearman’s rank correlation and Pearson’s chi-square tests were performed to determine the association of the respondents’ sociodemographic and medical profiles with their corresponding infection prevention practices. Results: Majority of respondents were between ages 30-50 (52.68%), female (71.43%), with college (83.93%) as their highest educational attainment, single (70.54%), and without comorbidities (66.07%). 76.5% (72/94) of respondents living in multi-person households lived with familial ties, and 59.6% (56/94) of respondents living in a multi-person household lived with at least one member considered a high-risk individual (i.e., a senior citizen with comorbidities). The respondents practiced face mask-wearing (4.92) and respiratory etiquette (4.90) the most, whereas reduction of unnecessary outings (3.81), not drinking alcohol (3.81), and sleeping at least 7 hours per day (3.42) were least practiced. Results showed that only age and having chronic kidney disease correlated with infection prevention practices with a p-value of <0.05, showing that people with chronic kidney disease and those aged 30-50 were more likely to engage in infection prevention practices. Conclusion The study findings provide insight into sociodemographic and medical factors that may contribute to adherence to infection prevention practices among the hospital-based workforce. Recommendations for further research were discussed.

Objective: To investigate the clinicopathological characteristics of occupational lung diseases, to reduce the missed diagnoses and misdiagnoses of the diseases and to help standardize the diagnosis and treatment of these patients. Methods: A total of 4 813 lung biopsy specimens (including 1 935 consultation cases) collected at the Department of Pathology, Nanjing Drum Tower Hospital, Nanjing, China from January 1st, 2017 to December 31th, 2019 were retrospectively analyzed. Among them, 126 cases of occupational lung diseases were confirmed with clinical-radiological-pathological diagnosis. Special staining, PCR and scanning electron microscopy were also used to rule out the major differential diagnoses. Results: The 126 patients with occupational lung diseases included 102 males and 24 females. All of them had a history of exposure to occupational risk factor(s). Morphologically, 68.3% (86/126) of the cases mainly showed pulmonary fibrotic nodules, dust plaque formation or carbon end deposition in pulmonary parenchyma. 16.7% (21/126) of the cases mainly showed welding smoke particle deposition in the alveolar cavity and lung interstitium while 15.1% (19/126) of the cases showed granulomas with fibrous tissue hyperplasia, alveolar protein deposition or giant cell interstitial pneumonia. The qualitative and semi-quantitative analyses of residual dust components in the lung under scanning electron microscope were helpful for the diagnosis of welder's pneumoconiosis and hard metal lung disease. Conclusions: The morphological characteristics of lung biopsy tissue are important reference basis for the clinicopathological diagnosis and differential diagnosis of occupational lung diseases. Recognizing the characteristic morphology and proper use of auxiliary examination are the key to an accurate diagnosis of occupational lung diseases on biopsy specimens.

Background: and Purpose Recent studies suggested an increased incidence of cerebral venous thrombosis (CVT) during the coronavirus disease 2019 (COVID-19) pandemic. We evaluated the volume of CVT hospitalization and in-hospital mortality during the 1st year of the COVID-19 pandemic compared to the preceding year. Methods: We conducted a cross-sectional retrospective study of 171 stroke centers from 49 countries. We recorded COVID-19 admission volumes, CVT hospitalization, and CVT in-hospital mortality from January 1, 2019, to May 31, 2021. CVT diagnoses were identified by International Classification of Disease-10 (ICD-10) codes or stroke databases. We additionally sought to compare the same metrics in the first 5 months of 2021 compared to the corresponding months in 2019 and 2020 (ClinicalTrials.gov Identifier: NCT04934020). Results: There were 2,313 CVT admissions across the 1-year pre-pandemic (2019) and pandemic year (2020); no differences in CVT volume or CVT mortality were observed. During the first 5 months of 2021, there was an increase in CVT volumes compared to 2019 (27.5%; 95% confidence interval [CI], 24.2 to 32.0; P<0.0001) and 2020 (41.4%; 95% CI, 37.0 to 46.0; P<0.0001). A COVID-19 diagnosis was present in 7.6% (132/1,738) of CVT hospitalizations. CVT was present in 0.04% (103/292,080) of COVID-19 hospitalizations. During the first pandemic year, CVT mortality was higher in patients who were COVID positive compared to COVID negative patients (8/53 [15.0%] vs. 41/910 [4.5%], P=0.004). There was an increase in CVT mortality during the first 5 months of pandemic years 2020 and 2021 compared to the first 5 months of the pre-pandemic year 2019 (2019 vs. 2020: 2.26% vs. 4.74%, P=0.05; 2019 vs. 2021: 2.26% vs. 4.99%, P=0.03). In the first 5 months of 2021, there were 26 cases of vaccine-induced immune thrombotic thrombocytopenia (VITT), resulting in six deaths. Conclusions During the 1st year of the COVID-19 pandemic, CVT hospitalization volume and CVT in-hospital mortality did not change compared to the prior year. COVID-19 diagnosis was associated with higher CVT in-hospital mortality. During the first 5 months of 2021, there was an increase in CVT hospitalization volume and increase in CVT-related mortality, partially attributable to VITT.

INTRODUCTION: Child sexual abuse (CSA) adversely affects a child's growth and well-being. This study aimed to describe the profile of children presenting to a tertiary paediatric emergency department(ED) with CSA. METHODS: Children 0-16 years old presenting to KK Women's and Children's Hospital ED from June 2016 to August 2020 with sexual abuse were retrospectively reviewed. We performed a secondary analysis on girls and stratified them by age <13 and ≥13 years old. RESULTS: There were 790 patients who made 833 visits for CSA. Victims were predominantly girls (747, 94.8%) and perpetrators were predominantly men (763, 96.6%). The abuse first occurred before the age of 13 years in 315 victims (39.9%). For 468 (59.2%), more than one incident occurred before presentation. Compared to girls ≥13 years old, girls <13 years old were more frequently abused by a family member (47.7% versus 8.0%, CONCLUSION The findings highlight common characteristics of CSA cases, and can aid the future identification and protection of vulnerable children. The fact that most children presented after more than one incident suggests the need to more closely monitor and protect potentially at-risk children.

Objective: The mandible is the most common fractured craniofacial bone of all craniofacial fractures in the Philippines, with the mandibular body as the most involved segment of all mandibular fractures. To the best of our knowledge, there are no existing guidelines for the diagnosis and management of mandibular body fractures in particular. General guidelines include the American Academy of Otolaryngology – Head and Neck Surgery Foundation (AAOHNSF) Resident Manual of Trauma to the Face, Head, and Neck chapter on Mandibular Trauma, the American Association of Oral and Maxillofacial Surgeons (AAOMS) Clinical Practice Guidelines for Oral and Maxillofacial Surgery section on the Mandibular Angle, Body, and Ramus, and a 2013 Cochrane Systematic Review on interventions for the management of mandibular fractures. On the other hand, a very specific Clinical Practice Guideline on the Management of Unilateral Condylar Fracture of the Mandible was published by the Ministry of Health Malaysia in 2005. Addressing the prevalence of mandibular body fractures, and dearth of specific guidelines for its diagnosis and management, this clinical practice guideline focuses on the management of isolated mandibular body fractures in adults. Purpose: This guideline is meant for all clinicians (otolaryngologists – head and neck surgeons, as well as primary care and specialist physicians, nurses and nurse practitioners, midwives and community health workers, dentists, and emergency first-responders) who may provide care to adults aged 18 years and above that may present with an acute history and physical and/or laboratory examination findings that may lead to a diagnosis of isolated mandibular body fracture and its subsequent medical and surgical management, including health promotion and disease prevention. It is applicable in any setting (including urban and rural primary-care, community centers, treatment units, hospital emergency rooms, operating rooms) in which adults with isolated mandibular body fractures would be identified, diagnosed, or managed. Outcomes are functional resolution of isolated mandibular body fractures; achieving premorbid form; avoiding use of context-inappropriate diagnostics and therapeutics; minimizing use of ineffective interventions; avoiding co-morbid infections, conditions, complications and adverse events; minimizing cost; maximizing health-related quality of life of individuals with isolated mandibular body fracture; increasing patient satisfaction; and preventing recurrence in patients and occurrence in others. Action Statements The guideline development group made strong recommendationsfor the following key action statements: (6) pain management- clinicians should routinely evaluate pain in patients with isolated mandibular body fractures using a numerical rating scale (NRS) or visual analog scale (VAS); analgesics should be routinely offered to patients with a numerical rating pain scale score or VAS of at least 4/10 (paracetamol and a mild opioid with or without an adjuvant analgesic) until the numerical rating pain scale score or VAS is 3/10 at most; (7) antibiotics- prophylactic antibiotics should be given to adult patients with isolated mandibular body fractures with concomitant mucosal or skin opening with or without direct visualization of bone fragments; penicillin is the drug of choice while clindamycin may be used as an alternative; and (14) prevention- clinicians should advocate for compliance with road traffic safety laws (speed limit, anti-drunk driving, seatbelt and helmet use) for the prevention of motor vehicle, cycling and pedestrian accidents and maxillofacial injuries.The guideline development group made recommendations for the following key action statements: (1) history, clinical presentation, and diagnosis - clinicians should consider a presumptive diagnosis of mandibular fracture in adults presenting with a history of traumatic injury to the jaw plus a positive tongue blade test, and any of the following: malocclusion, trismus, tenderness on jaw closure and broken tooth; (2) panoramic x-ray - clinicians may request for panoramic x-ray as the initial imaging tool in evaluating patients with a presumptive clinical diagnosis; (3) radiographs - where panoramic radiography is not available, clinicians may recommend plain mandibular radiography; (4) computed tomography - if available, non-contrast facial CT Scan may be obtained; (5) immobilization - fractures should be temporarily immobilized/splinted with a figure-of-eight bandage until definitive surgical management can be performed or while initiating transport during emergency situations; (8) anesthesia - nasotracheal intubation is the preferred route of anesthesia; in the presence of contraindications, submental intubation or tracheostomy may be performed; (9) observation - with a soft diet may serve as management for favorable isolated nondisplaced and nonmobile mandibular body fractures with unchanged pre - traumatic occlusion; (10) closed reduction - with immobilization by maxillomandibular fixation for 4-6 weeks may be considered for minimally displaced favorable isolated mandibular body fractures with stable dentition, good nutrition and willingness to comply with post-procedure care that may affect oral hygiene, diet modifications, appearance, oral health and functional concerns (eating, swallowing and speech); (11) open reduction with transosseous wiring - with MMF is an option for isolated displaced unfavorable and unstable mandibular body fracture patients who cannot afford or avail of titanium plates; (12) open reduction with titanium plates - ORIF using titanium plates and screws should be performed in isolated displaced unfavorable and unstable mandibular body fracture; (13) maxillomandibular fixation - intraoperative MMF may not be routinely needed prior to reduction and internal fixation; and (15) promotion - clinicians should play a positive role in the prevention of interpersonal and collective violence as well as the settings in which violence occurs in order to avoid injuries in general and mandibular fractures in particular.
