BACKGROUND

The COVID-19 pandemic brought insurmountable changes, leading to work demands and resource limitations that placed additional physical and occupational stress.

This study aimed to determine the change in the occurrence and intensity of musculoskeletal discomfort among selected university faculty members. It also determined the association of sociodemographic and anthropometric factors, workplace conditions, and involvement in physical activity with musculoskeletal pain.

This is an analytical cross-sectional study conducted from June 2022 to May 2023 that surveyed university faculty members from Metro Manila and Metro Cebu. Outcome measures include sociodemographic data, anthropometric measures of weight, height, body mass index, workplace conditions, exercise participation, and musculoskeletal discomfort using the Cornell Musculoskeletal Discomfort Questionnaire.

Data from 120 participants, mostly female, with an average BMI of 27.78 ± 12.09 kg/m2 and 11.82 ± 10.39 years of teaching experience revealed increased computer usage and reduced teaching hours during the Pandemic lockdown. There was also prevalent musculoskeletal discomfort (MSD), particularly in the neck, shoulder, and upper back. Factors associated with increased MSD were female gender, longer computer use, and pre pandemic MSD history.

This study underscores the significance of addressing ergonomic factors and work conditions to mitigate MSD risks among educators during challenging situations.

OBJECTIVE

Despite being a preventable and treatable condition, central microbial keratitis (CMK) and its complications remain to be a significant cause of vision loss in our country. This study presents the demographic profile, risk factors, etiologies, treatments, and outcomes of CMK in the Philippines.

The study was a two-center, prospective, non-randomized clinical study involving the patients of the External Disease and Cornea Clinics of two tertiary eye referral centers in the Philippines. It was conducted as the Philippine leg of the Asia Cornea Society Infectious Keratitis Study (ASCIKS).1 Patients with a clinical diagnosis of CMK rendered by a cornea specialist, and who signed the consent form, were recruited into the study. They underwent uniform sample collection and culture techniques as described in the ACSIKS. All patients were followed-up for 6 months. Data collected included demographics, risk factors, culture results, management, and treatment outcomes. Descriptive statistics and frequency were used to analyze the data.

A total of 348 patients diagnosed with CMK were included. Trauma (65.5%) among the middle-aged (42.9 ± 17.9 years) male population was the most significant risk factor for development of CMK, followed by contact lens wear (12.9%), prior ocular surgery (6.0%), and ocular surface diseases (3.4%). Bacterial keratitis (53.2%) was still the most common etiology of CMK, followed by fungal keratitis (27.0%), Acanthamoeba keratitis (5.7%), and viral keratitis (2.0%). Aspergillus species (18.3%) were the most common microbial isolates. Pseudomonas species (13.9%) were the most common bacterial isolates. The median time from onset of symptoms to consultation with the study centers was 2 weeks. Medical treatment was enough to treat the infection in 34.8% of cases. Surgical intervention was necessitated in 22.6% with evisceration/enucleation done in 1 out of 3 patients who had surgery.

Bacterial infection remains the most common cause of CMK in the Philippines, followed by fungal infection. Significant risk factors include trauma and contact lens wear. Aspergillus species and Pseudomonas species were the most common fungal and bacterial isolates, respectively. Despite medical treatment, almost a quarter of the cases still required surgical intervention.

Objective: To determine the relationship between olfactory function threshold and quality of life (QOL) among adult Filipinos with perceived olfactory dysfunction (OD). Methods: Design:Cross - Sectional Study. Setting:Tertiary Government Training Hospital. Participants: 98 adults who had self-perceived olfactory dysfunction described as “poor” or “no sense” of smell Results: We analyzed data from 98 participants, with a mean age of 35.91 + 12.58 years old, composed of 46 men (47%) and 52 women (53%), with 82 normosmic, six hyposmic and ten anosmic as categorized by their BTT scores. Twenty-seven percent (27%) identified themselves as having poor QOL based on Fil 17 QODNS. Differences were exhibited between sexes’ BTT scores - [t(96) = -2.32; p = .022; females, M: 9.25; SD: 2.33 vs. males, M: 7.76; SD : 3.91], civil status - Fil17QODNS scores [t(96)= 3.05, p < .003; married M: 11.72, SD: 13.74 vs. single, M: 4.71; SD: 8.66), and the presence of ENT symptoms BTT [t(96) = -7.15; p < .0001; symptomatic, M: 5.62; SD: 4.54, vs. asymptomatic, M: 9.78; SD: 1.14] and Fil 17 QODNS scores [t(96)= 3.94; P < .00001; symptomatic, M: 14.86; SD: 13.97] vs. asymptomatic, M: 5.217; SD: 9.60]. Significant risk factors were the presence of ENT symptoms [OR= 0.15; 95% CI: 0.02-0.97; P = .046] for poor smell threshold, and comorbidities [OR= 3.36; 95% CI: 1.04-10.85; P = .043] for poor QOL. A negative correlation was observed between Fil-QOD-NS scores and BTT scores [r = -0.477, p < .001; rs = -0.292, p = .004], signifying that the presence of olfactory dysfunction has an inverse relationship with the quality of life. Conclusion Individuals with olfactory dysfunction in this study population had poor quality of life as determined by the translated Filipino 17-item QOD-NS which has an inverse relationship with their smell threshold as represented by the BTT results. Among the factors studied, significant differences were found between sexes, civil status and presence of ENT symptoms in the BTT and Fil 17 QODNS scores. However, only presence of comorbidities and ENT symptoms are significant risk factors for quality of life and smell threshold, respectively, in this population.

Objective: To analyze the clinical characteristics of infection of COVID-19 Omicron variants in children with allergic diseases. Methods: This was a cross-sectional retrospective study. A total of 657 pediatric patients with allergic diseases aged between 0-17 years confirmed with COVID-19 infection were enrolled from the Children's Hospital affiliated to Capital Institute of Pediatrics from January to March 2023. The median age was 6.6(4.7,9.9) years, with 443 males (67.4%) and 214 females (32.6%). Demographic data, vaccination status, clinical manifestations, therapeutic drugs, and other data were collected. The patients were then divided into different groups according to the age, type of allergic diseases and vaccination status, and their clinical characteristics were compared. Results: A total of 657 children with allergic diseases were included in this study, among them 568 with asthma. Fever is the most common symptoms after COVID-19 infection (627/657, 95.4%), and 509 children (77.5%) with high fever. Cough was observed in 446 (67.9%) and fatigue in 167 (25.4%) cases.10 cases (1.5%) were diagnosed as pneumonia. The proportion of pharyngalgia(22%,84/382, χ²=19.847, P<0.01), fatigue (31.7%, 121/382,χ²=23.831, P<0.01), headache(34.6%, 132/382,χ²=57.598, P<0.01), muscle joint pain(16.0%, 61/382,χ²=22.289, P<0.01) and vomiting(11.0%, 42/382,χ²=12.756, P<0.01) were highest in the>6 years group. Children younger than 3 years had the lowest proportion of runny nose(8.8%, 5/57,χ²=8.411, P<0.01), cough(45.6%, 26/57,χ²=6.287, P<0.05) and expectoration(7.0%, 4/57,χ²=5.950, P<0.05). 62.8%(137/218) of the patients in 3-6 year group had the highest rate of cough(χ²=6.287, P<0.05), with a higher proportion of wheezing (10.1%, 22/218). Cough and/or wheezing symptoms were most quickly relieved in the 6 year old group, who had a highest proportion of 68.8%(260/382) in duration of respiratory symptoms within 1 week compared with 52.2% (114/218)of 3-6 years group and 41.2% (22/57)of<3 year group, respectively(χ²=23.166, P<0.01). The asthma group had a significant higher proportion of cough(59.7% vs 41.6%, χ²=10.310, P<0.01), wheezing (8.5% vs 0.0%, χ²=8.114, P<0.01) and expectoration (19.2% vs 7.9%, χ²=10.310, P<0.01) than that of non-asthma group. Besides, patients with cough and/or wheezing in the asthma group had more impact on exercise and sleep (16.1% vs 0, χ²=5.436, P<0.05) and a longer duration over 4 weeks (25.1% vs 3.7%, χ²=6.244, P<0.05). Conclusions: The most common symptoms in children with allergy infected with COVID-19 Omicron variant were fever and cough. Children under 3 years of age had relatively fewer respiratory symptoms while those with asthma or aged 3-6 years were more likely to have cough and wheezing and longer duration of symptoms. The data suggested that the prevention and management of COVID-19 should be strengthened in children with allergy.

OBJECTIVE: To investigate the status quo of recognition and management of renal colic among urological surgeons in China. METHODS: From November 2021 to March 2022, 725 urological surgeons in China were surveyed in the form of a questionnaire, including their province, hospital grade, professional title, the number of patients with renal colic treated per week, the preferred drugs and the cognition of the disease. This study was approved by the Medical Ethics Committee of Peking University People's Hospital, and all respondents completed informed consent online. RESULTS: During November 2021 and March 2022, urological surgeons across China were surveyed in the form of a questionnaire, and the reliability and validity of the questionnaire were verified before the study was carried out. In the study, 720 valid questionnaires were collected (accounting for 99.31% of the total number), in which 42.4% of the doctors' preferred drugs were non-steroidal anti-inflammatory drugs (NSAIDs), and 40.0% of the doctors' preferred antispasmodic drugs. Opioids were the first choice of 11.0% of the physicians and other treatments were preferred by 6.6% of physicians. In addition, 61.1% of the doctors thought that the mechanism of renal colic was elevated prostaglandin, 32.2% thought it was ureteral spasm, 5.0% thought it was calculi irritation, and 1.7% thought the mechanism was unclear. The doctor of the cognition of the generation mechanism of renal colic pain had a significant influence on the preferred treatment option (χ²=54.399, P < 0.001) that the "elevated prostaglandins" doctor more often preferred NSAIDs than the doctor who thought cramps and ureter stones caused renal colic (51.6% vs. 28.0%, χ²=34.356, P < 0.001;51.6% vs. 19.4%, χ²=13.759, P < 0.001). In addition, hospital class, physician title, and the number of weekly consultations by physicians influenced the choice of medications for renal colic (P < 0.05), tertiary hospitals, middle and senior professional titles and weekly patients with renal colic > 8 cases generally preferred NSAIDs. CONCLUSION There are deficiencies in the cognition and drug treatment of renal colic among urological surgeons in China. The choice of the preferred drug was related to the doctor's cognition of the disease, the grade of the hospital, the doctor's professional title and the weekly treatment volume.

OBJECTIVE: To investigate the significance of anti-histidyl tRNA synthetase (Jo-1) antibody in idiopathic inflammatory myopathies (IIM) and its diseases spectrum. METHODS: We enrolled all the patients who were tested positive for anti-Jo-1 antibody by immunoblotting in Peking University People's Hospital between 2016 and 2022. And the patients diagnosed with anti-synthetase antibody syndrome (ASS) with negative serum anti-Jo-1 antibody were enrolled as controls. We analyzed the basic information, clinical characteristics, and various inflammatory and immunological indicators of the patients at the onset of illness. RESULTS: A total of 165 patients with positive anti-Jo-1 antibody were enrolled in this study. Among them, 80.5% were diagnosed with connective tissue disease. And 57.6% (95/165) were diagnosed with IIM, including ASS (84/165, 50.9%), immune-mediated necrotizing myopathy (7/165, 4.2%) and dermatomyositis (4/165, 2.4%). There were 23.0% (38/165) diagnosed with other connective tissue disease, mainly including rheumatoid arthritis (11/165, 6.7%), undifferentiated connective tissue disease (5/165, 3.0%), interstitial pneumonia with autoimmune features (5/165, 3.0%), undifferentiated arthritis (4/165, 2.4%), Sjögren's syndrome (3/165, 1.8%), systemic lupus erythematosus (3/165, 1.8%), systemic vasculitis (3/165, 1.8%), and so on. Other cases included 3 (1.8%) malignant tumor patients, 4 (2.4%) infectious cases and so on. The diagnoses were not clear in 9.1% (15 /165) of the cohort. In the analysis of ASS subgroups, the group with positive serum anti-Jo-1 antibody had a younger age of onset than those with negative serum anti-Jo-1 antibody (49.9 years vs. 55.0 years, P=0.026). Clinical manifestations of arthritis (60.7% vs. 33.3%, P=0.002) and myalgia (47.1% vs. 22.2%, P=0.004) were more common in the ASS patients with positive anti-Jo-1 antibody. With the increase of anti-Jo-1 antibody titer, the incidence of the manifestations of arthritis, mechanic hands, Gottron sign and Raynaud phenomenon increased, and the proportion of abnormal creatine kinase and α-hydroxybutyric dehydrogenase index increased in the ASS patients. The incidence of myalgia and myasthenia were significantly more common in this cohort when anti-Jo-1 antibody-positive ASS patients were positive for one and more myositis specific antibodies/myositis associated autoantibodies (P < 0.05). CONCLUSION The disease spectrum in patients with positive serum anti-Jo-1 antibody includes a variety of diseases, mainly ASS. And anti-Jo-1 antibody can also be found in many connective tissue diseases, malignant tumor, infection and so on.

Dental primary afferent (DPA) neurons and proprioceptive mesencephalic trigeminal nucleus (MTN) neurons, located in the trigeminal ganglion and the brainstem, respectively, are essential for controlling masticatory functions. Despite extensive transcriptomic studies on various somatosensory neurons, there is still a lack of knowledge about the molecular identities of these populations due to technical challenges in their circuit-validated isolation. Here, we employed high-depth single-cell RNA sequencing (scRNA-seq) in combination with retrograde tracing in mice to identify intrinsic transcriptional features of DPA and MTN neurons. Our transcriptome analysis revealed five major types of DPA neurons with cell type-specific gene enrichment, some of which exhibit unique mechano-nociceptive properties capable of transmitting nociception in response to innocuous mechanical stimuli in the teeth. Furthermore, we discovered cellular heterogeneity within MTN neurons that potentially contribute to their responsiveness to mechanical stretch in the masseter muscle spindles. Additionally, DPA and MTN neurons represented sensory compartments with distinct molecular profiles characterized by various ion channels, receptors, neuropeptides, and mechanoreceptors. Together, our study provides new biological insights regarding the highly specialized mechanosensory functions of DPA and MTN neurons in pain and proprioception.

Objective:To analyze the influencing factors and perform the prediction of olfactory disorders in patients with chronic rhinosinusitis（CRS） based on artificial intelligence. Methods:The data of 75 patients with CRS who underwent nasal endoscopic surgery from October 2021 to February 2023 in the Department of Otorhinolaryngology Head and Neck Surgery, the Third Affiliated Hospital of Sun Yat-sen University were analyzed retrospectively. There were 53 males and 22 females enrolled in the study, with a median age of 42.0 years old. The CRS intelligent microscope interpretation system was used to calculate the proportion of area glands and blood vessels occupy in the pathological sections of each patient, and the absolute value and proportion of eosinophils, lymphocytes, plasma cells and neutrophils. The patients were grouped according to the results of the Sniffin' Sticks smell test, and the clinical baseline data, differences in nasal mucosal histopathological characteristics, laboratory test indicators and sinus CT were compared between the groups. Determine the independent influencing factors of olfactory disorders and receiver operating characteristic curves（ROC） were used to evaluate the performance of the prediction model. Statistical analysis was performed using SPSS 25.0 software. Results:Among the 75 CRS patients, 25 cases（33.3%） had normal olfaction and 50 cases（66.7%） had olfactory disorders. Multivariate Logistic regression analysis showed that tissue eosinophils percentage（OR=1.032, 95%CI 1.002-1.064, P=0.036）, Questionnaire of olfactory disorders-Negative statement（QOD-NS）（OR=1.079, 95%CI 1.004-1.160, P=0.040） and Anterior olfactory cleft score（AOCS）（OR=2.672, 95%CI 1.480-4.827, P=0.001） were independent risk factors for olfactory disorders in CRS patients. Further research found that the area under the ROC curve（AUC） of the combined prediction model established by the tissue eosinophil percentage, QOD-NS and AOCS was 0.836（95%CI 0.748-0.924, P<0.001）, which is better than the above single factor prediction model in predicting olfactory disorders in CRS. Conclusion:Based on pathological artificial intelligence, tissue eosinophil percentage, QOD-NS and AOCS are independent risk factors for olfactory disorders in CRS patients, and the combination of the three factors has a good predictive effect on CRS olfactory disorders.
