BACKGROUND

Blood pressure (BP) is a vital sign that is essential in the management of hypertension, thus, there is a need for accurate measurement of BP. This will allow for proper diagnosis and management of hypertension preventing cardiovascular morbidity and mortality among Filipino patients.

This validation study utilized the US Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization (AAMI/ESH/ISO) protocol for BP monitors. A total of eighty-five (85) participants had their BP measured using both the HEM 7156 and a validated aneroid sphygmomanometer. The same-sequential BP measurement was recommended to be used and a total of nine readings were collected per individual. The mean average of BP and standard deviation were extracted from the measurements. The AAMI/ESH/ISO recommends the use of certain criteria for individual BP readings (criterion 1) and individual participants (criterion 2). Appropriate statistical analysis was used for other demographic data.

The participants had an average age of 34 years, more than half were females, and not diagnosed with hypertension. Individuals who were diagnosed with hypertension had no other comorbidities and were on single pill only. The average arm circumference was 26.9 cm. Blood Pressure (BP) readings were adequate based on the protocol. Validity results showed that for criterion 1, systolic blood pressure (SBP) difference was 3.4 ± 7.4 mmHg, while diastolic blood pressure (DBP) was 2.0 ± 8.0 mmHg. The results for criterion 2 showed for SBP was 3.3 ± 5.3 mmHg, while DBP was 1.9 ± 6.6 mmHg. The results satisfied a passing grade on the validation protocol set by the AAMI/ESH/ISO.

This study showed that OMRON HEM 7156 is validated as a BP apparatus and may be recommended for Philippine use.

OBJECTIVES

Acanthamoeba spp. are free-living amoebae commonly found in aquatic environments, with pathogenic genotypes capable of causing severe diseases such as acanthamoeba keratitis and granulomatous amoebic encephalitis. Environmental factors, particularly pH, influence their survival and distribution. Tadlac Lake located at Los Baños, Laguna, Philippines is a Class C freshwater body used for aquaculture, recreation, and irrigation. To date, no study has specifically assessed Acanthamoeba colonization in Tadlac Lake.

In this study, detection of the presence of Acanthamoeba spp. and evaluation of pH as a potential factor influencing their persistence in Tadlac Lake was conducted. One-time sampling was conducted from nine sites of the lake. Surface water samples were collected at a depth of 10–20 cm, filtered through 1.2 μm glass microfiber filters, and cultured on non-nutrient agar plates lawned with live Escherichia coli. Plates were incubated at 30°C for 14 days and examined daily under light microscopy, while pH was measured in situ.

Cyst-like structures resembling amoebae were observed, but these did not exhibit definitive Acanthamoeba morphology under light microscopy. No Acanthamoeba spp. were confirmed and the recorded pH levels ranged from 8.72 to 10.51, exceeding the optimal growth range (7.0–9.0) reported for the organism.

Findings of this study suggest alkaline conditions may have inhibited the proliferation and persistence of Acanthamoeba spp. in the lake. These findings highlight pH as a potential limiting factor for Acanthamoeba survival in alkaline freshwater bodies and underscore the importance of integrating physicochemical monitoring into pathogen surveillance frameworks.

In the Philippines, organ donation is regulated under the Organ Donation Act (RA7170) and promoted by the Department of Health through the Philippine Network for Organ Sharing (PHILNOS). The number of organ donors to meet the increasing demand in the country continues to lag. The emergency department (ED) was identified in several foreign studies to be a significant source of successful organ donation. This action research project investigated the attitude and perception of 125 ED healthcare workers (HCWs) from three hospitals in Metro Manila before and after an awareness event. The study reveals that ED nurses and doctors are generally supportive and hold positive perceptions and attitudes toward organ donation. Despite the positive attitude, HCWs seem to be uncomfortable or unwilling to perform tasks important to organ donation such as approaching relatives and management of the deceased organ donor. Future training on organ donation will increase the positive attitude, confidence and likelihood to participate in organ donation and transplant activities.

Purpose: In the context of COVID-19, studies evaluating the adherence of dentists and dental students to infection control are relevant due to their high occupational exposure and risk, as well as their responsibility for disseminating information and good practices. This study evaluated the adherence of dentists and dental students to infection control in the oral radiology field in the setting of the COVID-19 pandemic on different continents. Materials and Methods: This cross-sectional observational study involved individuals who performed intraoral radiographic examinations during the COVID-19 pandemic. The Questionnaire on Infection Control in Oral Radiology was administered virtually using a Google Form. Participants from different continents (the Americas, Africa, Europe, Asia, and Oceania) were recruited. Data were subjected to descriptive analysis and simple and multiple binary regression (5%). Results: There were 582 valid answers, and 68.73% of the participants were from the Americas, 18.90% from Europe, and 12.37% from Asia. The median score for infection control protocols was 94 points for dental students and 104 points for dentists, and participants below the median were considered to have low adherence to infection control in oral radiology. Low access to infection control was found for 53.0% of dentists in the Americas, 34.0% from Europe, and 26.9% from Asia. Conclusion The adherence to infection control protocols in oral radiology was low even in the face of the COVID-19 pandemic. The results may help improve the awareness of students and professionals, since oral radiology routines have the potential for transmitting COVID-19.

BACKGROUND

Coronary artery disease is the leading cause of death in the Philippines and can present as acute coronary syndrome. Hospitalization for ACS has epidemiologic and economic burden. In fact, last 2017, there were 1.52% or 152 admissions for every 10,000 hospitalized patients for medical conditions in PhilHealth-accredited hospitals locally. However, coronary angioplasty was performed in only less than 1% of these cases mainly because of its cost and the out-of-pocket expense that the treatment entail, when primary percutaneous intervention has been proven to be effective in reducing mortality in STEMI and early invasive intervention performed during index hospitalization for NSTEMI is likewise recommended. Moreover, there is a big disparity between the current case rates for ACS for medical therapy alone and for invasive intervention compared to the actual ACS hospitalization cost.

1) To propose revisions to the current PhilHealth case rates for acute coronary syndrome (ACS); and 2) To determine the budget impact of the proposed ACS case rates.

The Philippine Heart Association with the assistance of a technical working group undertook the study. A panel of experts composed of general and invasive cardiologists from Luzon, Visayas, and Mindanao was formed. The ACS hospitalization costs based on the recent study by Mendoza were presented and discussed during the focus group discussions with the panelists. Issues pertinent to their localities that may affect the costs were discussed. The proposed revised costs on the particular ACS conditions and therapeutic regimens were then voted and agreed upon. A budget impact analysis of the proposed case rates was then performed.

The proposed case rates for ACS ranged from Php 80,000 (for low risk unstable angina given medical treatment) to Php 530,000 (for ST-elevation myocardial infarction initially given a thrombolytic agent then underwent PCI which necessitated the use of three stents). The budget impact analysis showed that the proposed ACS rates would require an additional PHP 1.5 billion to 2.3 billion during the first year of a 3- versus 5-year implementation period, respectively. The period of implementation will be affected by budgetary constraints as well as the availability of cardiac catheterization facilities in the country.

The proposed revised PhilHealth hospitalization coverage for ACS is more reflective or realistic of the ACS hospitalization costs in contrast with the current PhilHealth case rates. The corresponding budget impact analysis of these proposed case rates showed that PHP 7.6 billion is needed for full implementation. However, given the budget constraints, the percentage of the total costs for the first and subsequent years of implementation may be modified.

BACKGROUND

Hospitalization for acute coronary syndrome (ACS) has epidemiologic and economic burden. The coverage for hospitalization in the local setting is much less than the actual costs. Many patients do not consent to or avail of the optimal and timely management because of financial challenges.

The paper aimed to propose revised PhilHealth case rates/packages for ACS, namely: 1) unstable angina (UA), 2) non-ST-elevation myocardial infarction (NSTEMI), and 3) STelevation myocardial infarction (STEMI).

A consensus panel was organized to provide inputs such as cost and other matters pertaining to the revision of the PhilHealth ACS case rates/packages. The results of the cost of hospitalization of the different ACS conditions derived from a study on hospitalization cost for ACS were presented to the panel. Several focused group discussions were held afterward for propositioning new case rates through votation and by nominal group technique, using the costs from the study as the bases of rate adjustment.

Final costs agreed upon by the consensus panel for medical management alone for UA, NSTEMI, and STEMI were adjusted or amended in increments of Php 20,000, (80,000, 100,000, and 120,000, respectively). Thrombolysis of a patient admitted for STEMI increased the cost to Php 140,000. An additional cost of Php 150,000 was added on top of the cost for medical management and coronary angiogram for NSTE- ACS for PCI with use of a single stent. For STEMI, the same category had an additional cost of Php 180,000. For each additional stent used for all clinical scenarios undergoing PCI, Php 65,000 was added, to cover up to a total of 3 stents.

Based on the consensus process with Philippine Heart Association ACS panelists, the cost proposed ranges from 80,000 pesos to 530,000 pesos depending on the clinical scenarios.

OBJECTIVE

This study aimed to determine the budget impact of the proposed revised PhilHealth case rate packages for acute coronary syndrome (ACS).

This budget impact analysis used the static approach or cost calculator modeling method. The prevalence of hospitalization for coronary artery disease in all PhilHealth-accredited hospitals in the country in 2017 and the data from the ACS registry project of the Philippine Heart Association were used in this study. The study multiplied the present PhilHealth coverage with the number of ACS hospitalization claims to come up with the total cost of ACS hospitalization in the next three years with the assumptions that the eligible population and the ACS PhilHealth case rates will remain constant for these years. The future ACS hospitalization costs were also determined if the proposed case rates were used rather than the current PhilHealth case rates. The cost of re-admissions was considered as savings in hospitalization cost (due to prevention of admissions if the appropriate interventions were given) and were deducted from the future total cost of ACS hospitalizations.

The annual total ACS hospitalization cost using the current case rates was Php 1,134,683,000. Using the proposed case rates, the total hospitalization costs over five years was Php 2,653,019,000 in the first year (proposed case rates implemented to only 20% of the ACS patients) and increased to Php 8,726,364,000 by year 5 (full implementation of the proposed case rates or to 100% of ACS patients). This resulted in a lower incremental cost in the first year of implementation compared with a less gradual implementation over 3 years. The total incremental costs would amount to PHP7.6 billion for full implementation.

The study provided the budget impact of the proposed revised ACS case rates. The incremental cost is relatively huge, however the benefits of providing coverage of guidelinedirected therapy including invasive strategies for ACS must be considered.

Biliary cystic tumors (BCT), which include the subgroups biliary cystadenoma (BCA) and biliary cystadenocarcinoma (BCAC), affect 5 to 10% of the global population. BCTs are solitary, multiloculated cysts that are usually intrahepatic in location. BCACs are rare tumors that arise from the malignant transformation of BCA. The presentation of BCT often mimics simple hepatic cysts and other hepatic cystic lesions making diagnosis difficult. With the recent advances in medical imaging, BCTs have been diagnosed more often. Patients with BCT are often asymptomatic. When symptoms are present, however, patients usually manifest with abdominal pain and distention. Given the high risk of recurrence, complete surgical resection by formal hepatic resection or enucleation is the best treatment of choice for patients. We present a case of a 65-year-old female who came in due to a four-year history of an enlarging abdomen. She was initially treated, preoperatively, as a case of ovarian new growth but was later managed as hepatic cystadenocarcinoma.

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.

PURPOSE: The use of tolerogenic dendritic cells (TolDCs) to control exacerbated immune responses may be a prophylactic and therapeutic option for application in autoimmune and allergic conditions. The objective of this work was to evaluate the effects of TolDC administration in a mouse model of allergic airway inflammation caused by mite extract. METHODS: Mouse bone marrow-derived TolDCs were induced by incubation with granulocyte-macrophage colony-stimulating factor (GM-CSF) and dexamethasone, and then characterized by flow cytometry and cytokine production by enzyme-linked immunosorbent assay (ELISA). For the in vivo model of Blomia tropicalis-induced allergy, mice transplanted with antigen-pulsed TolDCs were sensitized intraperitoneally with B. tropicalis mite extract (BtE) adsorbed to aluminium hydroxide. After challenge by nasal administration of BtE, bronchoalveolar lavage fluid (BALF), lungs, spleen and serum were collected for analysis. RESULTS: Induction of TolDCs was efficiently achieved as shown by low expression of major histocompatibility complex (MHC) II, programmed death-ligand (PD-L) 2 and pro-inflammatory cytokine production, and up-regulation of interleukin (IL)-10, upon LPS stimulation in vitro. Transplantation of 1 or 2 doses of BtE-pulsed TolDCs reduced the number of inflammatory cells in BALF and lungs as well as mucus deposition. Moreover, compared to saline-injected controls, TolDC-treated mice showed lower serum levels of anti-BtE immunoglobulin E (IgE) antibodies as well as reduced Gata3 and IL-4 gene expression in the lungs and decreased IFN-γ levels in the supernatant of splenocyte cultures Transplantation of TolDCs increased the percentage of the regulatory T cells in the spleen and the lungs. CONCLUSIONS: Preventive treatment with TolDCs protects against dust mite-induced allergy in a mouse model, reinforcing the use of tolerogenic dendritic cells for the management of allergic conditions.
