RESUMEN

Objective@#This study aimed to find changes in the job satisfaction of emergency physicians (EP) and suggest ways to objectively measure indicators of satisfaction for future surveys. @*Methods@#A total of 2,138 emergency physicians were surveyed, using email questionnaires from January to February of 2021. The factors related to their job satisfaction were analyzed. @*Results@#Emergency physicians’ satisfaction was low. The average number of times they experienced violence per year was 4.3±4.9 per year. Work intensity and salary satisfaction improved than those in the 2010, and 2015 Korean Emergency Physician Survey (KEPS). Health status, such as drowsiness, and depression rates, were low. Forty-three percentage of EPs said they would reapply for the emergency specialty. @*Conclusion@#Despite the increase in extrinsic indicators, job satisfaction remained low compared to those in the 2010, and 2015 KEPS. To improve job satisfaction, non-quantitative factors should be considered. It would be necessary to evolve a separate survey on job satisfaction and conduct regular surveys in this regard.

RESUMEN

A nasal polyp is a distinct mucosal pathology that obstructs the nasal cavity and paranasal sinuses, with various phenotypes and endotypes. Nasal polyps should be distinguished from inverted papillomas, squamous cell carcinomas, juvenile angiofibromas, lymphomas, and olfactory neuroblastomas. A choanal polyp is a solitary benign lesion that originates in the paranasal sinus and extends to the choana through the natural ostium of the sinus. Choanal polyps usually originate from the maxillary sinus; however, we recently experienced the case of 41-year old women with sinochoanal polyp originated from the ethmoid sinus. As choanal polyps can recur even after appropriate surgery, complete resection, including the surrounding mucosa at the site of origin, is required. Therefore, it is essential to consider anatomical differences in polypectomy. We recently diagnosed and successfully performed surgery on an ethmochoanal polyp; herein, we report our experience and present a literature review.

RESUMEN

Background@#There is insufficient data on the benefits of empiric antibiotic combinations for hospital-acquired pneumonia (HAP). We aimed to investigate whether empiric antipseudomonal combination therapy with fluoroquinolones decreases mortality in patients with HAP. @*Methods@#This multicenter, retrospective cohort study included adult patients admitted to 16 tertiary and general hospitals in Korea between January 1 and December 31, 2019.Patients with risk factors for combination therapy were divided into anti-pseudomonal non-carbapenem β-lactam monotherapy and fluoroquinolone combination therapy groups.Primary outcome was 30-day mortality. Propensity score matching (PSM) was used to reduce selection bias. @*Results@#In total, 631 patients with HAP were enrolled. Monotherapy was prescribed in 54.7% (n = 345) of the patients, and combination therapy was prescribed in 45.3% (n = 286).There was no significant difference in 30-day mortality between the two groups (16.8% vs.18.2%, P = 0.729) or even after the PSM (17.5% vs. 18.2%, P = 0.913). After the PSM, adjusted hazard ratio for 30-day mortality from the combination therapy was 1.646 (95% confidence interval, 0.782–3.461; P = 0.189) in the Cox proportional hazards model. Moreover, there was no significant difference in the appropriateness of initial empiric antibiotics between the two groups (55.0% vs. 56.8%, P = 0.898). The proportion of multidrug-resistant (MDR) pathogens was high in both groups. @*Conclusion@#Empiric anti-pseudomonal fluoroquinolone combination therapy showed no survival benefit compared to β-lactam monotherapy in patients with HAP. Caution is needed regarding the routine combination of fluoroquinolones in the empiric treatment of HAP patients with a high risk of MDR.

RESUMEN

Background@#and Purpose Physical frailty is known to be closely associated with cognitive impairment and to be an early sign of Alzheimer’s disease. We aimed to understand the characteristics of physical frailty and define factors associated with physical frailty in subjects with subjective cognitive decline (SCD) by analyzing amyloid data. @*Methods@#We prospectively enrolled subjects with SCD from a cohort study to identify predictors for the clinical progression to mild cognitive impairment or dementia from SCD (CoSCo). All of the subjects underwent brain magnetic resonance imaging, and brain amyloid positron-emission tomography (PET) to detect amyloid beta plaques. Self-reported exhaustion, handgrip strength, and gait speed were used to measure physical frailty. @*Results@#Of 120 subjects with SCD, 26 (21.7%) were amyloid-positive in PET. Female (odds ratio [OR]=3.79, p=0.002) and amyloid-PET-positive (OR=3.80, p=0.008) subjects with SCD were at high risks of self-reported exhaustion. Amyloid PET positivity (OR=3.22, p=0.047) and high burden from periventricular white-matter hyperintensity (OR=3.34, 95% confidence interval=1.18–9.46, p=0.023) were significantly associated with a weaker handgrip. The subjects with SCD with self-reported exhaustion and weaker handgrip presented with lower cognitive performance in neuropsychological tests, especially for information processing speed and executive function. Subjects with a slower gait performed worse in visual memory function tests. @*Conclusions@#Amyloid PET positivity was associated with a higher risk of self-reported exhaustion and weaker handgrip in subjects with SCD. The subjects with SCD and physical frailty also performed worse in neuropsychological tests.

RESUMEN

Background/Aims@#There are limitations in treating ampullary adenomas with intraductal extension using conventional endoscopic modalities. Endoscopic intraductal radiofrequency ablation (ID-RFA) may be useful for treating intraductal (common bile duct [CBD] and/or pancreatic duct [PD]) extensions of ampullary adenomas, but long-term data are lacking. We thus evaluated the long-term outcomes of endoscopic ID-RFA for managing ampullary adenomas with intraductal extension. @*Methods@#Prospectively collected endoscopic ID-RFA database at Asan Medical Center was reviewed to identify consecutive patients with ampullary adenoma who underwent ID-RFA for intraductal extension between January 2018 and August 2021. Technical success, short-term and long-term clinical success, and adverse events were evaluated. @*Results@#A total of 29 patients (14 CBD, 1 PD, and 14 CBD and PD) were analyzed. All patients had undergone endoscopic snare papillectomy prior to ID-RFA. A median of one session of IDRFA (range, 1 to 3) for residual or relapsed intraductal extension of ampullary adenoma were successfully performed (technical success=100%). Both biliary and pancreatic stenting were routinely performed after ID-RFA to prevent ductal stricture. After a median follow-up of 776 days (interquartile range, 470 to 984 days), the short-term and long-term clinical success rates were 93% and 76%, respectively. Seven patients experienced procedural adverse events and three patients developed ductal strictures. @*Conclusions@#Endoscopic ID-RFA showed good long-term outcomes in treating residual or relapsed ampullary adenomas with intraductal extension. Repeated ID-RFA may be considered as an option for managing recurrence. Further studies are needed to standardize the procedure.

RESUMEN

Objective@#It is difficult to predict the treatment response of tissue after stereotactic radiosurgery (SRS) because radiation necrosis (RN) and tumor recurrence can coexist. Our study aimed to predict tumor recurrence, including the recurrence site, after SRS of brain metastasis by performing a longitudinal tumor habitat analysis. @*Materials and Methods@#Two consecutive multiparametric MRI examinations were performed for 83 adults (mean age, 59.0 years; range, 27–82 years; 44 male and 39 female) with 103 SRS-treated brain metastases. Tumor habitats based on contrastenhanced T1- and T2-weighted images (structural habitats) and those based on the apparent diffusion coefficient (ADC) and cerebral blood volume (CBV) images (physiological habitats) were defined using k-means voxel-wise clustering. The reference standard was based on the pathology or Response Assessment in Neuro-Oncologycriteria for brain metastases (RANO-BM). The association between parameters of single-time or longitudinal tumor habitat and the time to recurrence and the site of recurrence were evaluated using the Cox proportional hazards regression analysis and Dice similarity coefficient, respectively. @*Results@#The mean interval between the two MRI examinations was 99 days. The longitudinal analysis showed that an increase in the hypovascular cellular habitat (low ADC and low CBV) was associated with the risk of recurrence (hazard ratio [HR], 2.68; 95% confidence interval [CI], 1.46–4.91; P = 0.001). During the single-time analysis, a solid low-enhancing habitat (low T2 and low contrast-enhanced T1 signal) was associated with the risk of recurrence (HR, 1.54; 95% CI, 1.01–2.35; P= 0.045). A hypovascular cellular habitat was indicative of the future recurrence site (Dice similarity coefficient = 0.423). @*Conclusion@#After SRS of brain metastases, an increased hypovascular cellular habitat observed using a longitudinal MRI analysis was associated with the risk of recurrence (i.e., treatment resistance) and was indicative of recurrence site. A tumor habitat analysis may help guide future treatments for patients with brain metastases.

RESUMEN

As the global coronavirus disease 2019 (COVID-19) pandemic continues to sweep across the globe, reports of kidney involvement in adult patients infected with COVID-19 have been documented, and recently, cases in the pediatric population have also been reported.This report highlights the case of an 11-year-old boy who developed acute kidney injury presenting as gross hematuria, proteinuria, and hypertension immediately after a COVID-19 infection. A renal biopsy allowed us to diagnose the patient with post-COVID-19 infectionassociated de novo crescentic immune-mediated glomerulonephritis. Oral prednisolone and cyclophosphamide treatments were initiated after methylprednisolone pulse therapy administration. Currently, the patient is receiving medical treatment for five weeks, and his renal function is gradually recovering. Previous studies have suggested that, although quite rare, a variety of kidney complications can occur after COVID-19 infection or vaccination, and it is recommended to monitor renal function through evaluation. Herein, we report a pediatric case of post-COVID-19 infection-associated de novo crescentic immune-mediated glomerulonephritis consistent with rapidly progressive glomerulonephritis.

RESUMEN

Snapping triceps syndrome is a rare disease in which the distal portion of the medial triceps dislocates over the medial epicondyle during flexion of the elbow. It is usually accompanied with ulnar nerve dislocation and double snapping is clinically important feature. Dynamic ultrasonography is useful diagnostic tool for snapping triceps syndrome and ulnar nerve dislocation. But it is often misdiagnosed as ulnar nerve dislocation alone. This review reports a case of 28-year-old professional golfer who had a single snapping on elbow, misdiagnosed as ulnar nerve dislocation alone and eventually diagnosed as ulnar nerve dislocation and snapping triceps syndrome and also reflects factors that are overlooked through first and second operations.

RESUMEN

Background@#With the introduction of Xpert MTB/RIF assay (Xpert), its incorporation into tuberculosis (TB) diagnostic algorithm has become an important issue. The aim of this study was to evaluate the performance of the Xpert assay in comparison with a commercial polymerase chain reaction (PCR) assay. @*Methods@#Medical records of patients having results of both Xpert and AdvanSure TB/NTM real-time PCR (AdvanSure) assays using the same bronchial washing specimens were retrospectively reviewed. @*Results@#Of the 1,297 patients included in this study, 205 (15.8%) were diagnosed with pulmonary TB. Using mycobacterial culture as the reference method, sensitivity of the Xpert assay using smear-positive specimens was 97.5%, which was comparable to that of the AdvanSure assay (96.3%, p=0.193). However, the sensitivity of the Xpert assay using smear-negative specimens was 70.6%, which was significantly higher than that of the AdvanSure assay (52.9%, p=0.018). Usng phenotypic drug susceptibility testing as the reference method, sensitivity and specificity for detecting rifampicin resistance were 100% and 99.1%, respectively. Moreover, a median turnaround time of the Xpert assay was 1 day, which was significantly shorter than 3 days of the AdvanSure assay (p<0.001). @*Conclusion@#In comparison with the AdvanSure assay, the Xpert assay had a higher sensitivity using smear-negative specimens, a shorter turnaround time, and could reliably predict rifampin resistance. Therefore, the Xpert assay might be preferentially recommended over TB-PCR in Korean TB diagnostic algorithm.

RESUMEN

Background/Aims@#Most studies on hospital-acquired pneumonia (HAP) have been conducted in intensive care unit (ICU) settings. This study aimed to investigate the microbiological and clinical characteristics of non-ICU-acquired pneumonia (NIAP) and to identify the factors affecting clinical outcomes in Korea. @*Methods@#This multicenter retrospective cohort study was conducted in patients admitted to 13 tertiary hospitals between July 1, 2019 and December 31, 2019. Patients diagnosed with NIAP were included in this study. To assess the prognostic factors of NIAP, the study population was classified into treatment success and failure groups. @*Results@#Of 526 patients with HAP, 379 were diagnosed with NIAP. Overall, the identified causative pathogen rate was 34.6% in the study population. Among the isolated organisms (n = 113), gram-negative bacilli were common pathogens (n = 91), such as Pseudomonas aeruginosa (n = 25), Acinetobacter baumannii (n = 23), and Klebsiella pneumoniae (n = 21). The multidrug resistance rates of A. baumannii, P. aeruginosa, and K. pneumoniae were 91.3%, 76.0%, and 57.1%, respectively. Treatment failure was significantly associated with K. pneumoniae (odds ratio [OR], 3.50; 95% confidence interval [CI], 1.35 to 9.05; p = 0.010), respiratory viruses (OR, 3.81; 95% CI, 1.34 to 10.82; p = 0.012), hematological malignancies (OR, 3.54; 95% CI, 1.57 to 8.00; p = 0.002), and adjunctive corticosteroid treatment (OR, 2.40; 95% CI, 1.27 to 4.52; p = 0.007). @*Conclusions@#The causative pathogens of NIAP in Korea are predominantly gram-negative bacilli with a high rate of multidrug resistance. These were not different from the common pathogens of ICU-acquired pneumonia.

RESUMEN

In this study, the Search Your Mind (S.Y.M., 心) project aimed to collect prospective digital phenotypic data centered on mood and anxiety symptoms across psychiatric disorders through a smartphone application (app) platform while using both centralized and decentralized research designs: the centralized research design is a hybrid of a general prospective observational study and a digital platform-based study, and it includes face-to-face research such as informed written consent, clinical evaluation, and blood sampling. It also includes digital phenotypic assessment through an application-based platform using wearable devices. Meanwhile, the decentralized research design is a non-face-to-face study in which anonymous participants agree to electronic informed consent forms on the app. It also exclusively uses an application-based platform to acquire individualized digital phenotypic data. We expect to collect clinical, biological, and digital phenotypic data centered on mood and anxiety symptoms, and we propose a possible model of centralized and decentralized research design.

RESUMEN

Background@#Avoiding causative allergens is important for controlling the clinical course of atopic dermatitis (AD). Allergen sensitization is influenced by many factors, such as the environmental factors. Although socioeconomic development, climate, and lifestyle have changed and the prevalence of allergic diseases has increased in Korea over the past few decades, there is little information about changes in common allergens over time. @*Objective@#This study aimed to identify the trends of common allergens in patients with AD over a 10-year period based on the results of the multiple allergen simultaneous test (MAST). @*Methods@#We retrospectively reviewed the medical records of 1,414 patients with AD (603 adults and 811 children) over a period of 10 years. The serum total immunoglobulin E (IgE) and specific IgE levels of 41 allergens were determined using the MAST. @*Results@#House dust and house dust mites were the most prevalent allergens in both adult and pediatric patients during the 10-year period; however, the percentage of higher-class responses has decreased in recent years. The number of patients sensitized to house dust, cats, and egg whites increased, whereas that of patients sensitized to cockroaches, storage mites, beef, and rice decreased for both adults and children. No significant changes were observed in the total number of sensitizing allergens over time. @*Conclusion@#Common allergens in patients with AD have change over time. Based on the findings of this study, physicians and patients should consider changing their disease prevention and management strategies.

RESUMEN

Objective@#Emergency medicine residents are expected to exhibit a poor health status due to excessive working hours and high stress. Because much of patient care depends on them, their health conditions will have a significant impact on patient outcomes. Our study was designed to analyze the health status of emergency medicine residents and the affecting factors using the 2019 Korean Emergency Medicine Residents Survey (KEMRS) results. @*Methods@#The study evaluated the self-rated health-defined percentage of responders who thought they were in good health. Based on this response, the influencing factors were categorized statistically. These factors included personal characteristics, lifestyle (drinking, smoking, eating, sleeping, and exercise), and emotional stress. @*Results@#Of a total of 384 respondents, 176 (46%) thought they were in good health. Participants who perceived themselves to be unhealthy included residents who were married, female, and those in the 3rd grade. Drinking and smoking were not perceived to affect health status, but regular exercise and proper eating patterns were seen to be positive influencing factors. Daytime sleepiness, depressive moods, and personal well-being were correlated with health status. @*Conclusion@#While personal characteristics and emotional problems cannot be changed easily, lifestyle changes can be made for better health. The health conditions of emergency residents have not been considered a matter of importance thus far. To overcome their health problems, responsible improvements in schedules and a program of long-term follow-ups need to be implemented, followed by training programs.

RESUMEN

Lifestyle is a critical aspect of diabetes management. We aimed to define a healthy lifestyle using objectively measured parameters obtained from a wearable activity tracker (Fitbit) in patients with type 2 diabetes. This prospective observational study included 24 patients (mean age, 46.8 years) with type 2 diabetes. Expectation–maximization clustering analysis produced two groups: A (n=9) and B (n=15). Group A had a higher daily step count, lower resting heart rate, longer sleep duration, and lower mean time differences in going to sleep and waking up than group B. A Shapley additive explanation summary analysis indicated that sleep-related factors were key elements for clustering. The mean hemoglobin A1c level was 0.3 percentage points lower at the end of follow-up in group A than in group B. Factors related to regular sleep patterns could be possible determinants of lifestyle clustering in patients with type 2 diabetes.

RESUMEN

Background@#The best option for the treatment of Neer type IIB lateral clavicle fractures remains controversial. The aim of this study was to compare outcomes and complications between pre-contoured locking plate osteosynthesis (PLPO) and coracoclavicular stabilization (CCS) using a TightRope for the treatment of type IIB fractures. @*Methods@#Forty-six consecutive type IIB fractures were treated with PLPO (17 cases) or CCS (29 cases). The mean follow-up period was 33.7 months (range, 12–144 months). Radiographic outcomes were evaluated using serial plain radiographs. Clinical outcomes were evaluated using the University of California, Los Angeles (UCLA) score, the American Shoulder and Elbow Surgeons (ASES) score, and subjective shoulder value (SSV). @*Results@#Of the 46 cases, complete bony union within 6 months after surgery was achieved in 42 cases (91.3%). The union rate was 100% (17/17) in the PLPO group and 86.2% (25/29) in the CCS group, showing a statistically significant difference (p = 0.043). No significant differences in terms of UCLA score (32.8 vs. 32.1), ASES score (93.2 vs. 90.8), or SSV (89.1% vs. 90.3%) were observed between the PLPO and CCS groups. The complication rates were 17.6% (3/17; 2 cases of screw breakage and 1 case of stiffness) in the PLPO group and 37.9% (11/29; 4 cases of nonunion, 3 cases of stiffness, 2 cases of skin irritation, 1 case of superficial infection, and 1 case of coracoid button migration) in the CCS group, showing no statistically significant difference (p > 0.05). Four cases with nonunion after CCS did not require reoperation because they had good to excellent clinical outcomes without radiographic progression. @*Conclusions@#Although a higher nonunion rate was observed in the CCS group compared with the PLPO group, satisfactory clinical outcomes were obtained for both groups. Both techniques can be regarded as useful options for the treatment of Neer type IIB lateral clavicle fractures.

RESUMEN

Background/Aims@#The continuous flow left ventricular assist device (cf-LVAD) has improved the survival of chronic end-stage heart failure (HF) patients. Here we describe our clinical experience of the initial 50 LVAD patients from a single center. @*Methods@#A total of 50 patients underwent LVAD implantation as bridge to transplantation (BTT; n = 28, 56%), bridge to candidacy (BTC; n = 2, 4%), or as destination therapy (DT; n = 20, 40%) from 2012 to 2019. Pre-implant characteristics and clinical outcomes were compared between BTT/BTC and DT. @*Results@#The median age of patients was 67 years (range, 59 to 73). Men were more likely to receive LVAD (76% vs. 24%) than women. DT patients were older, had smaller body surface area, and worse laboratory profiles than BTT/BTC patients. There was no in-hospital mortality. During an average of 14 months (range, 8 to 23), the all-cause mortality was 22%. The first-year survival was 86 and 90% in BTT/BTC and DT groups, respectively. Hemorrhagic stroke was the most common cause (27%) of death. In the BTT/BTC group, 22 patients successfully underwent heart transplantation during median duration of 10 months (range, 7 to 14). The most common post-LVAD complication during the first year of LVAD implantation was major bleeding (44%). A significant proportion (76%) of patients experienced rehospitalization with gastrointestinal bleeding as the most common cause. @*Conclusions@#We describe short-term clinical outcome of LVAD patients from a single center for the first time in Korea. With the newer generation LVAD and a dedicated team approach, improved clinical outcomes of LVAD for end-stage HF are expected.

RESUMEN

Objective@#Among various causes of insomnia, stress is the most common and representative cause. Insomnia is also known to negatively affect the quality of life (QoL). The objective of this study was to explore the effect of stress on QoL and the mediating role of insomnia symptoms in the relationship between stress and QoL. @*Methods@#In this study, the mediating effect of insomnia symptoms on the relationship between stress and QoL was analyzed by enrolling 3,714 participants from the Ansung and Ansan cohorts of the Korea Association Resource project from 2001 to 2004. These cohort participants were asked about how much they felt stressed during their everyday life. Insomnia symptoms were evaluated by asking participants whether they had trouble sleeping such as difficulty in falling asleep, disrupted sleep, and early morning awakening due to the lack of a validated questionnaire for this cohort. QoL was evaluated using the World Health Organization QoL Scale Brief Version. @*Results@#In total, stress was positively associated with insomnia symptoms, which in turn predicted QoL. The same result could be derived from subgroup analysis according to sex, and it was confirmed that insomnia symptoms acted as a mediating factor more significantly in female than in male. @*Conclusion@#In this study, insomnia symptoms were confirmed to act as a significant mediating factor between stress and QoL, suggesting that insomnia symptoms should be actively identified and controlled to alleviate the negative effect of stress on QoL in clinical practice.

RESUMEN

Objective@#We aimed to present the study design and baseline cross-sectional participant characteristics of biobank innovations for chronic cerebrovascular disease with Alzheimer’s disease study (BICWALZS) participants. @*Methods@#A total of 1,013 participants were enrolled in BICWALZS from October 2016 to December 2020. All participants underwent clinical assessments, basic blood tests, and standardized neuropsychological tests (n=1,013). We performed brain magnetic resonance imaging (MRI, n=817), brain amyloid positron emission tomography (PET, n=713), single nucleotide polymorphism microarray chip (K-Chip, n=949), locomotor activity assessment (actigraphy, n=200), and patient-derived dermal fibroblast sampling (n=175) on a subset of participants. @*Results@#The mean age was 72.8 years, and 658 (65.0%) were females. Based on clinical assessments, total of 168, 534, 211, 80, and 20 had subjective cognitive decline, mild cognitive impairment (MCI), Alzheimer’s dementia, vascular dementia, and other types of dementia or not otherwise specified, respectively. Based on neuroimaging biomarkers and cognition, 199, 159, 78, and 204 were cognitively normal (CN), Alzheimer’s disease (AD)-related cognitive impairment, vascular cognitive impairment, and not otherwise specified due to mixed pathology (NOS). Each group exhibited many differences in various clinical, neuropsychological, and neuroimaging results at baseline. Baseline characteristics of BICWALZS participants in the MCI, AD, and vascular dementia groups were generally acceptable and consistent with 26 worldwide dementia cohorts and another independent AD cohort in Korea. @*Conclusion@#The BICWALZS is a prospective and longitudinal study assessing various clinical and biomarker characteristics in older adults with cognitive complaints. Details of the recruitment process, methodology, and baseline assessment results are described in this paper.

RESUMEN

BACKGROUND/OBJECTIVES@#Adequate nutritional intake is essential for good health and well-being. We aimed to compare the nutrient intake from homemade meals, meals sourced externally (“eating out”), and meals from workplace foodservices, as well as the potential association between foodservices used and nutritional quality among adult Korean workers. @*SUBJECTS/METHODS@#We used data from the Korea National Health and Nutrition Examination Survey, a nationwide cross-sectional survey on the health and nutritional status of the Korean population. Data from 6,845 workers aged 20–64 years were included. A survey on dietary behavior and nutrition was conducted using the 24-h dietary recall method.Nutritional quality was examined using the index of nutritional quality (INQ) score. Higher INQ scores reflected poorer nutritional quality, with insufficient intake of a higher number of nutrients. Multivariate linear regression was used to identify the association between the foodservices used and INQ scores after adjusting for other covariates. @*RESULTS@#We found that foodservice users exhibited a higher 1-day intake of total energy and macronutrients (all P < 0.05) and lower INQ scores (P < 0.01) than non-users. The INQ scores for total daily meals decreased with the frequency of foodservice use (P < 0.01). A significant association was observed between the non-use of foodservices and INQ scores (β = 0.29, P < 0.01) after adjusting for other covariates. @*CONCLUSIONS@#The use of workplace foodservices contributed to higher dietary nutritional quality among workers. This study highlights the importance of expanding the scope of workplace foodservices to promote higher nutritional quality and healthy dietary habits among workers.

RESUMEN

Infection and sepsis in preterm infants are a leading cause of morbidity and mortality. Compared with full-term infants, preterm infants are more susceptible to infection owing to their distinct immune function, prolonged hospitalization, and higher likelihood of undergoing invasive procedures. Timely recognition and intervention are the key factors for good prognosis. This requires rapid and accurate diagnosis and empirical antibiotics against the pathogen based on each neonatal intensive care unit's epidemiology. Judicious anti biotics use is important following accurate identification of the causative pathogen. Simultaneous supportive management such as breast feeding should be encouraged to improve an infant’s defense mechanism. In essence, prevention is paramount because sepsis is known to contribute to significant neuro­developmental sequelae. Thorough understanding of immune function, good diagnostic protocol, appropriate antibiotics management, and strict preventive strategies may improve short- and long-term outcomes in premature infants.
