Clinical characteristics, management, and survival of retinoblastoma patients: a five-year study at an Indonesian tertiary eye hospital

Background Studies on the clinical characteristics of retinoblastoma in Indonesia have been limited, even though retinoblastoma is the most common pediatric ocular malignancy worldwide and the second-most common pediatric malignancy in Indonesia. The estimated patient survival rate in lower-middle-income countries is 77%, and survival is highly dependent on early diagnosis and therapy. Objective To identify the clinical characteristics of retinoblastoma in patients at the Cicendo National Eye Hospital, as an Indonesian tertiary eye hospital. Methods This retrospective, observational study included pediatric patients <18 years of age diagnosed with retinoblastoma at the Cicendo National Eye Hospital, Bandung, West Java, between January 2018 and December 2022. We collected patients’ medical record data on age, gender, laterality, chief complaints, stage of disease, grouping, histopathologic features, therapy, and survival. Results Of 247 retinoblastoma patients (328 eyes) enrolled, 53.85% presented at 1-2 years of age and 50.61% were males. Patients mostly presented with unilateral (67.21%) retinoblastoma, leukocoria (51.82%) as the chief complaint, and classified as International Retinoblastoma Staging System (IRSS) stage III (33.20%). Tumors were mostly intraocular (58.84%), particularly group E (39.02%). Most tumors showed undifferentiated (45.43%) and high-risk features (54.27%). Most eyes were treated with combination therapy (74.09%), particularly local and systemic therapy (59.45%). Survival was noted at 18.62% of patients, but 62.75% of patients were lost to follow-up. Conclusion Most patients present with advanced retinoblastoma. Most histopathological results shows undifferentiated and high-risk features of the tumor. Delays in diagnosis and therapy may occur due to a lack of awareness and knowledge regarding clinical manifestations of retinoblastoma, which leads to worse prognosis.

Correlation Between MTB/RIF Gene Xpert Cycle Threshold Values and Clinical Radiological Severity of Pulmonary Tuberculosis

The determination of bacterial load was essential for assessing disease severity, transmission rate, and prognosis. Gene Xpert is a diagnostic test that provides Cycle Threshold (Ct) value as a potential measure of Mycobacterium Tuberculosis (Mtb) load. Despite its potential, there are limited reports exploring the relationship between Ct value and clinicoradiological severity. This study aimed to correlate Ct value and clinicoradiological severity of pulmonary tuberculosis (TB). The study was a retrospective design using medical record data of confirmed TB patients from January to December 2022. These patients were identified based on Gene Xpert test and classified as high, moderate, or low detection Mtb when Ct value was <16, 16-22, and 22-28, respectively. In assessing the severity of clinical using the Bandim score, thoracic TB lesions was categorized by Chest XRay into minimal, moderate, and advanced. The total of 90 TB patients and the majority were males (78.9%) aged 46-65 years (59.0%), with comorbidities (95.0%). The most of the participants had mild clinical severity (44.4%), with Ct value of 16-22 (52.2%), and moderate lesions (35.6%). The most common lesions were fibroinfiltrates on the chest X-ray (61.1%). The Ct value of <16 had a significant correlation with clinical severity of TB (p<0.05) but no significant association with advanced lesions (p>0.05). Based on the results, Ct value had a strong correlation with clinical severity in pulmonary TB. In addition, it could be used as a predictor for managing pulmonary TB patients and an important indicator for control programs.

Association between Geriatric 8 frailty and health-related quality of life in older patients with cancer (PROGNOSIS-G8): a Danish single-centre, prospective cohort study

Health-related quality of life (HRQoL) is highly valued among older adults with cancer. The Geriatric 8screening tool identifies individuals with frailty, but its association with HRQoL remains sparsely investigated. Herein, we evaluate whether Geriatric 8frailty is associated with short-term and long-term HRQoL in older patients with cancer. In this Danish single-centre, prospective cohort study, patients aged 70years and older, referred to oncological assessment for solid cancers, were screened with the Geriatric 8. Patients completed the European Organisation for Research and Treatment of Cancer (EORTC) Quality-of-Life Core 30 (QLQ-C30) and Elderly 14(ELD14) questionnaires at baseline, 3months, 6months, 9months, and 12months. Patient characteristics were obtained from medical records. Differences in mean global health status and QoL (GHS), measured using the two seven-point Likert scale questions from the EORTC QLQ-C30 regarding overall health and QoL during the past week, between patients with frailty (defined as a Geriatric 8score of ≤14) and without frailty within 12months were the primary outcome. Secondary outcomes were differences in the mean EORTC Summary Score comprised of all questions from the QLQ-C30 except for those included in the GHS and a question concerning financial difficulties, and five functional (physical, role, and social functioning, maintaining purpose, and family support from the EORTC QLQ-C30 and the EORTC-QLQ-ELD14), and five symptom scales (fatigue, pain, mobility, future worries, and burden of illness from the EORTC-QLQ-C30 and the EORTC-QLQ-ELD14). Analyses were done using linear mixed models. All primary and secondary outcomes were adjusted for gender, treatment intent, and cancer type and the primary outcome was also assessed by means of a responder analysis. Between June 1, 2020and Oct 15, 2021, 1398eligible patients were screened with the Geriatric 8 (908 [65%] with frailty and 490 [35%] without frailty) and provided medical record data. Of these patients, 707 (51%) also provided HRQoL data (437 [62%] with frailty and 270 [38%] without frailty). When adjusted, patients with frailty had poorer GHS(-15·1, 95% CI -18·5to -11·6; p<0·0001) at baseline and throughout follow-up (3 months -7·4, -11·0to -3·7, p=0·0001; 6months -11·7, -15·5to -7·9, p<0·0001; 9months -10·4, -14·3to -6·5, p<0·0001; 12months -10·4, -14·6to -6·2, p<0·0001) compared to patients without frailty. Adjusted summary scores were also poorer for patients with frailty (-9·9, 95% CI -12·1to -7·6; p<0·0001) compared to patients without frailty at baseline and throughout follow-up (3 months -8·2, -10·5to -5·8, p=0·0001; 6months -9·0, -11·4to -6·6, p<0·0001; 9months -9·2, -11·7to -6·8, p<0·0001; 12 months -8·9, -11·5to -6·3, p<0·0001). Patients with frailty had significantly worse physical and role functioning, mobility, and fatigue outcomes, with no differences in family support within 12months, at all timepoints. Older patients with cancer and frailty have significantly poorer HRQoL than those without frailty within the 12months following an oncology referral. Thus, by identifying and treating frailty, we can ultimately improve patient HRQoL.

Pengelompokan Data Rekam Medis pada Pasien Penyakit dalam Untuk Meningkatkan Manajemen Informasi Kesehatan Berdasarkan Wilayah Kota Binjai Menggunakan Algoritma Clustering K- Means

The history of disease in patients is generally recorded in medical record data in every hospital as well as at Artha Medika Hospital which is a health institution that was established in 2012 in the city of Binjai also has a very large amount of medical record data. However, in using the information management system owned by Artha Medika Hospital, there are weaknesses and it is still limited in managing medical record data in the hospital which is used in making reports to the head of the leadership. Therefore, a system is needed that can assist the hospital in improving health information management to be faster in managing data by approaching using data mining techniques with the k-means method. So that in finding new information based on medical record data of internal medicine patients can be used in the decision-making process by hospital management to be right on target so that it can produce 3 groups of data consisting of Age, Type of disease and Region. From testing on cluster 3, it can be seen that the results of the age group (X), type of disease (Y), region (Z) the amount of data owned is 645 cluster 3 data centred on the centroid of the information of the number of patient medical records data, namely age is 44-52 years, with the type of disease is chronic kidney disease and the region is South Binjai.

Population-level cascade of care for hepatitis C in Newfoundland and Labrador

Background: Global elimination of hepatitis C virus (HCV) is feasible using existent tools. Reporting the provincial HCV care cascade will contribute to national and global HCV elimination efforts. Methods: This observational study was a secondary use of population-level medical record data, including laboratory results for HCV testing and prescription data for HCV treatment in the province of Newfoundland and Labrador (NL). All patients with HCV antibody testing performed between Jan 1, 2017 and Jan 1, 2022 were included. All prescriptions dispensed from a community pharmacy in NL for any HCV treatment during the same period were included. Results: There were 84,252 antibody tests included. Of these, 3,626 (4.3%) tests were positive for HCV antibodies. Seventy eight percent (1,377/1,766) of the individuals with positive antibody tests were tested for HCV RNA. Only 377/1,061 (35.5%) individuals with a positive RNA test were treated, and 257/395 (65.1%) achieved sustained virological response at 12 weeks. Conclusions: NL has successfully identified and treated HCV, but treatment access is low. Targets for improvement include increased screening, reflex testing of positive antibody with RNA, increased linkage to care, change in treatment funding policy, and quicker treatment funding decision.

Development and acceptability of a digital tool for promoting syphilis testing in Australian general practice: qualitative study using the Theoretical Framework of Acceptability.

Background In Australia, syphilis notifications increased 2.5-fold during 2013-2022 and 83 congenital syphilis cases were reported. Timely diagnosis and management are crucial. We developed a tool to promote syphilis testing into our existing 'Future Health Today' (FHT) software and explored its acceptability in general practice. Methods Our tool (FHT-syphilis) scans electronic medical record data to identify and prompt testing for pregnant women, and, people recently tested for sexually transmissible infection (STI) or HIV, but not syphilis. It links to relevant guidelines and patient resources. We implemented FHT-syphilis in 52 general practices using FHT for other conditions and interviewed practice clinicians (n =9) to explore it's acceptability. Data were analysed deductively guided by the Theoretical Framework of Acceptability. Results Interviewees considered syphilis an important infection to focus on and broadly viewed FHT-syphilis as acceptable for identifying patients and giving clinicians authority to discuss syphilis testing. Time constraints and unrelated reasons for a patient's visit were barriers to initiating syphilis testing discussions. Australian STI guidelines were considered appropriate to link to. Some interviewees considered prompts should be based on sexual behaviour, however this is not well captured in the electonic medical record. Two interviewees were alerted to updated Australian STI guidelines via their interaction with FHT-syphilis and expanded their syphilis testing practices. Expertise to initiate discussions about syphilis and risk was deemed important. Conclusions A digital tool for prompting syphilis testing was acceptable to clinicians already using FHT. Linkage to STI guidelines alerted some end-users to updated guidelines, informing STI testing practices.

Drug Prescribing Evaluation to Foreign Travelers in Bali: A Study of Two Travel Clinics

Bali is one of the world's favorite travel destinations in developing countries. Most travelers who travel to developing countries seek medical assistance before, during and after travelling. Irrational prescribing is one of the causes of the higher medical cost. The objective was to evaluate drug prescriptions to foreign travelers in 2 travel clinics in Bali using the WHO prescribing indicators. This retrospective study used a cross-sectional method. Foreign travelers who took medication and received drug therapy at the travel clinics from January until December 2019 and had complete and legible medical record data were included in this study. Drug prescription were evaluated by following the WHO prescribing indicators, including the number of drugs per prescription sheet, the percentage of prescription drugs with generic names, the percentage of antibiotic prescriptions, the percentage of prescribed injections, and the percentage of drugs that were in accordance with the formulary. Drug use was said to berationalifall indicators were in accordance with WHO prescribing indicators where as it was said to be irrational if it did not meet the indicators set by WHO. We found a total number of prescriptions was 220 and the number of types of drugs in this study was 544. We found many poly pharmacy events, low prescriptions with generic names (14,2%), not all prescriptionsmetnationalformulary (64,8%), high prescriptions of antibiotic (50,0%) and injection (29,1%). Through this study, we concluded that there has been a phenomenon of irrational prescribing in those travel clinics.

Evaluation of Machine Learning Algorithms for Pressure Injury Risk Assessment in a Hospital with Limited IT Resources.

Clinical decision support systems for Nursing Process (NP-CDSSs) help resolve a critical challenge in nursing decision-making through automating the Nursing Process. NP-CDSSs are more effective when they are linked to Electronic Medical Record (EMR) Data allowing for the computation of Risk Assessment Scores. Braden scale (BS) is a well-known scale used to identify the risk of Hospital-Acquired Pressure Injuries (HAPIs). While BS is widely used, its specificity for identifying high-risk patients is limited. This study develops and evaluates a Machine Learning (ML) model to predict the HAPI risk, leveraging EMR readily available data. Various ML algorithms demonstrated superior performance compared to BS (pooled model AUC/F1-score of 0.85/0.8 vs. AUC of 0.63 for BS). Integrating ML into NP-CDSSs holds promise for enhancing nursing assessments and automating risk analyses even in hospitals with limited IT resources, aiming for better patient safety.

Cohort Builder: A Software Pipeline for Generating Patient Cohorts with Predetermined Baseline Characteristics from Medical Records and Raw Ophthalmic Imaging Data.

In clinical research, the analysis of patient cohorts is a widely employed method for investigating relevant healthcare questions. The ability to automatically extract large-scale patient cohorts from hospital systems is vital in order to unlock the potential of real-world clinical data, and answer pivotal medical questions through retrospective research studies. However, existing medical data is often dispersed across various systems and databases, preventing a systematic approach to access and interoperability. Even when the data are readily accessible, clinical researchers need to sift through Electronic Medical Records, confirm ethical approval, verify status of patient consent, check the availability of imaging data, and filter the data based on disease-specific image biomarkers. We present Cohort Builder, a software pipeline designed to facilitate the creation of patient cohorts with predefined baseline characteristics from real-world ophthalmic imaging data and electronic medical records. The applicability of our approach extends beyond ophthalmology to other medical domains with similar requirements such as neurology, cardiology and orthopedics.

Factors Influencing Facial Paralysis Recovery: A Retrospective Cohort Study Using Electronic Medical Records.

This study aims to report on treatment outcomes and related factors in Bell's palsy patients by analyzing Electronic Medical Records (EMR) data. To assess the impact on the duration until improvement in House-Brackmann grading post-onset, we conducted an analysis of inpatient records for Bell's palsy patients admitted to a traditional Korean medicine hospital from 2018 to 2022. A total of 1049 subjects were included in the analysis. Contributing factors to a duration of more than 14 days until improvement in HB Grade included age 40 or above, male gender, an initial period of more than 7 days from onset to admission, a history of past recurrence, and the indication for adjunctive therapy. To generalize the adaptation of adjunctive traditional Korean medicine treatment indications to treatment outcomes, larger-scale studies encompassing a broader patient population will be necessary.

An external facilitation case study analysis of an implementation trial of FLOW: A program for improving the transition of patients with mental health disorders back to primary care.

FLOW (not an acronym) is a program that aims to improve mental health (MH) access using an algorithm that extracts electronic medical record data to identify recovered or stabilized MH patients who may be eligible to transition to primary care. The purpose of this case study was to describe and understand the factors that contributed to success or struggles in implementing FLOW. We conducted a posthoc evaluation of four health care sites implementing FLOW, using a mixed-method formal case study analysis. Qualitative data included written process notes, teleconference minutes, and interviews with internal facilitators (IF), MH providers, and patients who were transitioned. The external facilitation team also examined the degree to which IF characteristics matched suggested criteria. Quantitative data included discharge percentages and the percentage of providers who transitioned ≥ three patients during implementation. Sites were considered successful if they: (a) discharged ≥ 3% of their unique MH patients and (b) had a preponderance of patients who were satisfied with their MH to primary care transition. This article discusses two successful and two struggling FLOW sites based on these and other criteria and the factors that contributed to these outcomes. These case study findings increased understanding of how to successfully implement FLOW. The importance of shared decision making, selection of the IF, role definition, as well as leadership and organizational support are key elements in fostering appropriate transitions.

Effect of Metformin on Peripheral Nerve Morphology in Type 2 Diabetes: A Cross-Sectional Observational Study.

Diabetic peripheral neuropathy (DPN) affects around 50% of the 500 million people with type 2 diabetes worldwide and is considered disabling and irreversible. The present study was undertaken to assess the effect of metformin on peripheral neuropathy outcomes in type 2 diabetes. 69 type 2 diabetes participants receiving metformin were recruited and underwent clinical assessment, peripheral nerve ultrasound, nerve conduction studies and axonal excitability studies. 318 participants who were not on metformin were also concurrently screened, and 69 were selected as disease controls and matched to the metformin participants for age, sex, diabetes duration, BMI, HbA1c and use of other diabetes therapies. Medical record data over the previous 20 years were analysed for previous metformin use. Mean tibial nerve cross-sectional area (CSA) was lower in the metformin group (metformin 14.1 ∓ 0.7 mm2, non-metformin 16.2 ∓ 0.9mm2, p=0.038), accompanied by reduction in neuropathy symptom severity (p=0.021). Axonal excitability studies demonstrated superior axonal function in the metformin group and mathematical modelling demonstrated that these improvements were mediated by changes in nodal Na+ and K+ conductances. Metformin treatment is associated with superior nerve structure, clinical and neurophysiological measures. Treatment with metformin may be neuroprotective in DPN.

Co-occurring autism, ADHD, and gender dysphoria in children, adolescents, and young adults with eating disorders: an examination of pre- vs. post-COVID pandemic outbreak trends with real-time electronic health record data.

Incidence rates of autism, attention-deficit/hyperactivity disorder (ADHD), and gender dysphoria (GD) are rising not only in the general population, but particularly among children, adolescents, and young adults with eating disorders (EDs). While ED rates have risen during the COVID pandemic, trends in co-occurring autism, ADHD, and GD have yet to be investigated in detail or at scale by way of large electronic medical record data. To investigate trends in rates of co-occurring autism, ADHD, and GD among children, adolescents, and young adults with EDs in years prior to and during the COVID-19 pandemic. We utilized a de-identified multinational electronic health records database (TriNetX) with 48,558 individuals aged 5-26 diagnosed with eating disorders (EDs) at least twice between 2017 and 2022. The primary predictor variable differentiated between the years of each person's index (first) ED diagnosis (2017-2019 vs. 2020-2022). The primary outcome variable was the rate of new co-occurring psychiatric diagnoses of autism, ADHD, and GD in the year following each patient's first ED diagnosis. We applied propensity score-matched multivariable logistic regressions to compare primary outcomes between 2017-2019 and 2020-2022. Our analysis included 17,445 individuals diagnosed with EDs in 2017-2019 (8% autism, 13.5% ADHD, 1.9% GD) and 31,113 diagnosed with EDs in 2020-2022 (8% autism, 14.6% ADHD, 3.2% GD). After 1:1 propensity score matching, 17,202 individuals from the 2017-2019 cohort were matched to peers mirroring the 2020-2022 cohort. Those diagnosed in 2020-2022 showed a 19% (aOR[95%CI]=1.19[1.07-1.33]), 25% (aOR=1.25[1.04-1.49]), and 36% (aOR=1.36[1.07-1.74]) increase in odds for autism, ADHD, and GD diagnoses, respectively, within the 365 days after the index EDs diagnosis, compared to the 2017-2019 cohort. Rates of autism, ADHD, and GD are significantly higher in individuals with ED in the post-pandemic 2020-2022 cohort in comparison to the pre-pandemic 2017-2019 cohort, even after controlling for baseline levels of co-occurring psychiatric diagnoses. Such findings reveal a critical gap in our current understanding of the totality of ways in which COVID-19 may have impacted the onset and clinical course of EDs, autism, ADHD, and GD among children, adolescents, and young adults.

Aboriginal young people's experiences of type 2 diabetes diagnosis, management and support: A qualitative study in the Kimberley region of Western Australia.

In Australia, Aboriginal and Torres Strait Islander young people in remote settings are most-affected by young onset type 2 diabetes (T2D). It is necessary to understand young people's experiences, including factors impacting on self-management, to improve models of care. A phenomenological methodology underpinned this qualitative study in Western Australia's Kimberley region. Two Aboriginal Community Controlled Health Services supported recruitment of seven Aboriginal young people aged 12-24 with T2D, who participated in interviews. A carer and health professional of one young person in each site were also interviewed and relevant medical record data reviewed to assist with triangulation of data. De-identified transcripts were inductively coded and a coding structure developed with oversight by a Kimberley Aboriginal researcher. Young people reported varied experiences and emotions relating to a T2D diagnosis. Most recounted this was upsetting and some reported current negative impact on emotional wellbeing. Challenges with understanding and managing diabetes were highlighted, particularly regarding healthy eating, physical activity and medication. Family are a prominent source of self-management support, with the intergenerational impact of diabetes being evident for each participant. Positive relationships with health professionals, entailing continuity of care, were valued. There are significant emotional and medical challenges for young people with T2D and their families. Recommendations from this work will contribute to the development of local resources and initiatives to improve diabetes-related support. SO WHAT?: Alongside broader efforts to support good health at the societal level, enhanced health education and family-oriented support structures including Aboriginal clinical staff for young people with T2D are needed.

Real-World Clinical Outcomes and Treatment Patterns Among Black and Non-Black Patients With Prostate Cancer Initiated on Apalutamide in a Urology Setting

Background: The use of androgen receptor signaling inhibitors, including apalutamide, in combination with androgen deprivation therapy is recommended for the treatment of metastatic castration-sensitive prostate cancer (mCSPC) and non-metastatic castration-resistant prostate cancer (nmCRPC). Objective: To describe real-world treatment patterns and clinical outcomes among patients with mCSPC or nmCRPC who initiated apalutamide in the United States. Methods: A retrospective cohort study of patients with mCSPC or nmCRPC who initiated apalutamide was conducted using electronic medical record data from US community-based urology practices (Feb. 1, 2017–April 1, 2022). Persistence with apalutamide was reported at 6-, 12-, and 18-months post treatment initiation. Clinical outcomes described up to 24 months after apalutamide initiation using Kaplan-Meier analyses included progression to castration resistance, castration resistance-free survival (CRFS), and metastasis-free survival (MFS). Outcomes were reported separately based on mCSPC or nmCRPC status and race (ie, Black or non-Black). Results: This study included 589 patients with mCSPC (mean age, 75.9 years) and 406 patients with nmCRPC (mean age, 78.8 years). Using a treatment gap of &gt;90 days, persistence with apalutamide at 12 months remained high for both the mCSPC (94.9%) and nmCRPC (92.7%) cohorts, and results were descriptively similar among Black and non-Black patients, and when a treatment gap of &gt;60 days was considered. In patients with mCSPC, overall progression to castration resistance rates at 12 and 24 months were 20.9% and 33.5%, and overall CRFS rates were 76.2% and 62.0%, respectively. In patients with nmCRPC, overall MFS rates at 12 and 24 months were 89.7% and 75.4%, respectively. Rates of these clinical outcomes were descriptively similar between Black and non-Black patients. Discussion: While clinical trials have demonstrated the efficacy and safety of apalutamide, there is limited real-world data describing treatment persistence and clinical outcomes among patients with mCSPC and nmCRPC who initiated apalutamide. Conclusions: In this real-world study of patients with mCSPC or nmCRPC initiated on apalutamide, treatment persistence was high and apalutamide demonstrated robust real-world effectiveness with respect to progression to castration resistance, CRFS, and MFS, overall and among Black and non-Black patients.

Iron deficiency resolution and time to resolution in an American health system

AbstractIron deficiency (ID) is a global health problem with consequences independent of anemia, including impaired cognition and exercise tolerance. The time from laboratory diagnosis to resolution of ID has not been defined. In a retrospective review of electronic medical record data from a Minnesota statewide health system, we identified patients with ID (ferritin level ≤25 ng/mL). Patients with at least 1 follow-up ferritin level within 3 years were included. Patients with a subsequent ferritin of ≥50 ng/mL were classified as having resolved ID. Descriptive statistics and time-to-event analyses were used to determine proportion of ID resolution and time to resolution, and to evaluate characteristics predictive of resolution. We identified 13 084 patients with ID between 2010 to 2020. We found that 5485 (41.9%) had resolution within 3 years of diagnosis, whereas 7599 (58.1%) had no documented resolution. The median time to resolution was 1.9 years (interquartile range, 0.8-3.9). Factors associated with greater likelihood of resolution included age of ≥60 years (adjusted hazard ratio [aHR], 1.56; 95% confidence interval [CI], 1.44-1.69]), male sex (aHR, 1.58; 95% CI, 1.48-1.70]) and treatment with intravenous iron (aHR, 2.96; 95% CI, 2.66-3.30). Black race was associated with a lower likelihood of resolution (aHR, 0.73; 95% CI, 0.66-0.80). We observed a high proportion of persistent ID and prolonged time to resolution overall, with greater risk of lack of resolution among females and Black individuals. Targeted knowledge translation interventions are required to facilitate prompt diagnosis and definitive treatment of this prevalent and correctable condition.

Hypoxia and Time of Useful Consciousness in Hypobaric Chamber at 25,000 feet in Aircrew at dr. Saryanto Health Institute of Aeronautics and Space

Introduction: Hypoxia is a condition characterized by insufficient oxygen supply to tissues which causes body tissues to fail to get adequate oxygen supply. Hypobaric hypoxia is generally recognized as the most serious physiological hazard during high-altitude flight. This puts active crew members at risk for hypoxia and so they rely on effective performance time (EPT) or time useful consciousness (TUC) to take appropriate corrective and protective actions when hypoxia occurs. This study aimed to describe TUC scores and hypoxia symptoms experienced by active flight crew at dr. Saryanto Health Institute of Aeronautics and Space in 2021. Methods: A descriptive research design using medical record data from 99 flight crew with simple random sampling. The variables in this study consisted of hypoxia symptoms and TUC scores. This study uses univariate analysis to see the frequency distribution of the variables of hypoxia symptoms and TUC score. Results: The results showed that 18.2% experienced cognitive symptoms, 4% experienced psychomotor symptoms, 16.2% experienced visual symptoms, 3% experienced psychological symptoms, 54.5% experienced non-spesific symptoms, and 37.4% did not feel any symptoms. Most of the flight crew (68.7%) had sufficient EPT/TUC scores (3-4 minutes). Conclusion: Active flight crews feel symptoms of hypoxia and have sufficient TUC scores.

The Effect of Maternal Parity on Preterm Birth Risk in Women with Short Mid-Trimester Cervical Length: A Retrospective Cohort Study.

Objectives: To evaluate the effect of maternal parity on the association between mid-trimester cervical length and preterm birth to elucidate the potential intricacies of this relationship. Methods: A retrospective cohort study using Electronic Medical Records (EMR) data. The study population included pregnant women with a singleton fetus and a short mid-trimester cervical length, recorded in the EMR system at a large health maintenance organization. Women were categorized by parity in the current pregnancy, and a statistical analysis was conducted to examine the relationship between parity and premature delivery. Results: Data were collected from 1144 records of cervical length measurements of 738 pregnancies obtained from the HMO database. The study population consisted of 259 nulliparous women (35.1%), 451 multiparous women (61.1%), and 28 grand multiparous women (3.8%). The results from the multivariate analysis of the primary outcome showed that nulliparity was significantly associated with an increased risk of premature delivery, with a risk of 1.557 for nulliparous women compared to parous women. Conclusions: In this study, a statistically significant association was found between nulliparity and preterm birth among women with a short mid-trimester cervical length. Nulliparous women were found to have a higher risk of preterm birth in the current pregnancy compared to parous women. Further research is needed to understand the underlying mechanisms and to develop targeted interventions to reduce the risk of premature birth in this population. These findings highlight the need to consider nulliparity as a potential risk factor in the management of pregnancies with a shortened cervix.
