Risk factors associated with 1-year mortality after osteoporotic hip fracture in Hawaiʻi: higher mortality risk among Native Hawaiians and other Pacific Islanders
Summary We studied factors affecting osteoporotic hip fracture mortality in Hawaiʻi, a region with unique geography and racial composition. Men, older adults, higher ASA score, lower BMI, and NHPI race were associated with higher mortality. This is the first study demonstrating increased mortality risk after hip fracture in NHPI patients. Purpose To estimate mortality rates and identify specific risk factors associated with 1-year mortality after osteoporotic hip fracture in Hawaiʻi. Methods A retrospective review of adults (≥ 50 years) hospitalized with an osteoporotic hip fracture at a large multicenter healthcare system in Hawaiʻi from 2011 to 2019. The Kaplan–Meier curves and log-rank tests examined survival probability by sex, age group, race/ethnicity, primary insurance, body mass index (BMI), and American Society of Anesthesiologists (ASA) physical status classification. After accounting for potential confounders, adjusted hazard ratios (aHR) and 95% confidence intervals (CI) were obtained from Cox proportional hazards regression models. Results We identified 1755 cases of osteoporotic hip fracture. The cumulative mortality rate 1 year after fracture was 14.4%. Older age (aHR 3.50; 95% CI 2.13–5.76 for ≥ 90 vs 50–69), higher ASA score (aHR 5.21; 95% CI 3.09–8.77 for ASA 4–5 vs 1–2), and Native Hawaiian/Pacific Islander (NHPI) race (aHR 1.84; 95% CI 1.10–3.07 vs. White) were independently associated with higher mortality risk. Female sex (aHR 0.64; 95% CI 0.49–0.84 vs male sex) and higher BMI (aHR 0.35; 95% CI 0.18–0.68 for obese vs underweight) were associated with lower mortality risk. Conclusion In our study, men, older adults, higher ASA score, lower BMI, and NHPI race were associated with significantly higher mortality risk after osteoporotic hip fracture. NHPIs are an especially vulnerable group and comprise a significant portion of Hawaiʻi’s population. Further research is needed to address the causes of higher mortality and interventions to reduce hip fractures and associated mortality.
Nontuberculous mycobacterial skin and soft tissue infection in Hawaiʻi
Background Hawaiʻi has the highest nontuberculous mycobacterial (NTM) lung infection prevalence in the United States. Limited data regarding skin and soft tissue infections (SSTI) due to NTM in Hawaiʻi exists. This study describes patient demographics, clinical courses of infection, treatment patterns, and clinical outcomes of NTM SSTIs in Hawaiʻi. Methods A retrospective chart review (n = 50) of patients diagnosed and treated at Hawaiʻi Pacific Health facilities for NTM SSTIs between January 2010 and July 2021 was conducted. Patient demographics, clinical course, and treatment data were collected from electronic medical records. Results Half of the patient population consisted of females, and the average age of patients during infection was 49 years (SD = 25.6). The majority of cases (80%) were caused by rapidly growing mycobacteria (RGM), most commonly Mycobacterium abscessus . NTM SSTI by race were Asian (48%), White (28%), and Native Hawaiian and Other Pacific Islanders (16%). Almost all Asian patients with NTM SSTI were Filipino or Japanese. Diagnosis was frequently delayed. The average time to diagnosis was 116 days. Most patients achieved complete resolution (72%) following a prolonged course of antimicrobial treatment (mean = 196 days) with surgical debridement. Conclusion Increased awareness among physicians and the community of non-mycobacterial skin infections is essential in Hawaiʻi due to the high prevalence of NTM and the high percentage of predisposed populations. Increased awareness of NTM could reduce delayed diagnosis and improve patient care. Further studies are required to inform optimal treatment and diagnostic strategies, improve patient outcomes, and aid public health surveillance efforts.

Physician recruitment and retention in an underserved community: the role of a premedical research program
Background Physician shortages are prevalent in medically underserved areas, where healthcare disparities hinder physician recruitment and retention. The Hawai‘i Pacific Health (HPH) Summer Student Research Program (SSRP) provides early clinical and research experiences to pre-med students from Hawai’i, potentially enhancing their qualifications, supporting medical school acceptance rates, and fostering commitment to practicing in Hawai’i. Objective To evaluate the association between SSRP participation and medical school admissions, career trajectories, and retention of healthcare professionals in Hawai‘i, a medically underserved region. Methods A 38-year retrospective analysis examined 393 SSRP alumni (1986–2023), tracking educational and career outcomes, such as medical school admission, residency, and practice location, through surveys and internet research. Results The program was associated with a 73% medical school admission rate. Of 393 alumni, 221 became physicians, with 74 practicing in Hawai‘i. Among those in training, 81% expressed plans to practice locally. The program produced 57 abstracts, 43 posters, 53 oral presentations, and 37 peer-reviewed publications while providing students with clinical exposure and physician mentorship. Conclusion Community-based SSRPs may support the recruitment, retention, and cultivation of local students for medical careers and potentially bolster the physician workforce in underserved regions like Hawai‘i. By embedding clinical and research experiences within the community, the program is associated with enhanced medical school admissions and may foster long-term physician retention, including subspecialists, in the local healthcare system. This community-engaged approach contributes to medical education literature and provides a replicable model for other underserved areas to build sustainable healthcare workforces.
Patterns of health care utilization of gout patients in Hawai‘i-high rates of emergency department utilization as compared to rheumatoid arthritis
Recent and comprehensive research of gout in the Pacific region and Hawai‘i is significantly lacking. This study was conducted to improve the understanding of the healthcare utilization of gout patients within a single health care system in Hawai‘i. The objective was to examine gout inpatient, outpatient and emergency department care within a single health care system in Hawai‘i. This study was a retrospective chart review of patients, ≥ 18 years admitted to three Hawai‘i Pacific Health facilities for a primary diagnosis of gout or rheumatoid arthritis (RA) from 2011 to 2017. Population data for the State of Hawai‘i was used to calculate visit rates per 1,000 Hawai‘i adults. Trend analysis was performed to compare changes over time. We studied gout health care utilization concurrently with RA to provide an internal comparison group for the healthcare utilization patterns of interest. Gout patients were primarily managed in the outpatient setting with high rates of emergency department visits. In contrast, RA patients were primarily managed in the outpatient setting, with low rates of emergency department visits. Both gout and RA patients had low rates of inpatient admissions. The cost of gout emergency department visits was approximately 3.4 times higher than gout outpatient visits. The rates for gout emergency department visits, outpatient visits, inpatients visits, and RA outpatient visits in 2017 were trending downward and significantly changed from 2011 (p <0.05). The rates for RA emergency department visits and inpatient visits were not significantly changed from 2011–2017. Gout care in Hawai‘i remains suboptimal with higher rates of emergency department visits, as compared to RA. Because emergency department visits are associated with higher cost, efforts should be made to reduce these emergency department visits to improve the quality of care.

Osteoporotic hip fracture mortality and associated factors in Hawai’i
SummaryThe 30-day mortality of osteoporotic hip fracture patients ≥ 50 years at Hawai’i Pacific Health (2015–2016) was 4.2%. Mortality increased to 17.1% (1 year), 24.5% (2 years), and 30.1% (3 years). Increased age, male sex, higher CCI score, primary insurance status-Medicare/Medicaid, and lower BMI were associated with increased mortality.PurposeThe objective of this study was to evaluate mortality and factors associated with mortality of osteoporotic hip fracture patients at community hospitals within a large healthcare system in Hawai’i.MethodsA retrospective chart review was conducted of 428 patients, ≥ 50 years, and hospitalized for a osteoporotic hip fracture from January 2015 to May 2016 within a large healthcare system in Hawai’i. Patient demographics, comorbidities, and treatment were collected from retrospective chart review. We determined the date of death by review of medical records and online public obituary records. We calculated 30-day, 90-day, 1-year, 2-year, and 3-year mortality after discharge for hip fracture admission. Multivariable logistic regression and proportional hazards regression were used to evaluate associations between variables and the mortality of the patients.ResultsThe 30-day and 90-day mortality after admission for hip fracture were 4.2% and 8.6%. One-year mortality, 2-year mortality, and 3-year mortality were 17.1%, 24.5%, and 30.1%, respectively. Through proportional hazards regression, older age (hazard ratio (HR) = 1.06, p < 0.001), high comorbidity load (HR = 1.30, p < 0.001), and primary insurance status-Medicare/Medicaid (HR = 3.78, p = 0.021) were associated with increased mortality, while female sex (HR = 0.54, p < 0.001) and higher BMI (HR = 0.94, p = 0.002) were associated with lower mortality.ConclusionAfter admission for osteoporotic hip fracture, the 30-day mortality was 4.2%. At 1 year, 2 years, and 3 years, mortality increased to 17.1%, 24.5%, and 30.1%, respectively. Increased age, male sex, higher Charlson comorbidity index score, primary insurance status-Medicare/Medicaid, and lower body mass index were associated with increased mortality.
Injury Risk in Pole Vaulters: The Impact of Landing Technique and Experience Level in an Observational Study of 1,012 Athletes and 6,751 Attempts
Pole vaulting is a complex track and field event where athletes sprint down a runway, using a flexible pole to propel themselves over a horizontal crossbar. While safety regulations have reduced catastrophic injury rates, lower extremity injuries remain prevalent and demand further investigation. However, injury risks remain a concern due to the complexity of the sport and repetitive fall from heights. This study aims to investigate the correlation between landing mechanics and injury rates in pole vaulting. The authors hypothesize that improper landing techniques significantly increase the risk of injury, particularly in less experienced athletes.  This study was conducted at a national indoor pole vault event consisting of 1,012 athletes, ranging from beginner to elite level. Data was collected on skill level, landing location and position, and injuries. Only injuries sustained during a competitive vault attempt were considered for data analysis, which included descriptive statistics.  The landing injury rate was low at 0.12%, with eight injuries occurring in 6,751 vault attempts. Notably, no injuries occurred in athletes with optimal landing mechanics. All reported injuries affected the lower extremities and were exclusively observed in less experienced vaulters. Though pole vaulting is a relatively safe sport, catastrophic injuries are possible and the injuries that do occur are preventable, as this study reveals they occur at a higher rate in inexperienced vaulters as well as with an improper landing technique. Coaches and athletes should emphasize proper landing techniques to prevent injuries and improve performance.
Initial uptake, time to treatment, and real-world effectiveness of all-oral direct-acting antivirals for hepatitis C virus infection in the United States: A retrospective cohort analysis
Data on initiation and utilization of direct-acting antiviral therapies for hepatitis C virus infection in the United States are limited. This study evaluated treatment initiation, time to treatment, and real-world effectiveness of direct-acting antiviral therapy in individuals with hepatitis C virus infection treated during the first 2 years of availability of all-oral direct-acting antiviral therapies. A retrospective cohort analysis was undertaken using electronic medical records and chart review abstraction of hepatitis C virus-infected individuals aged >18 years diagnosed with chronic hepatitis C virus infection between January 1, 2014, and December 31, 2015 from the Indiana University Health database. Eight hundred thirty people initiated direct-acting antiviral therapy during the 2-year observation window. The estimated incidence of treatment initiation was 8.8%±0.34% at the end of year 1 and 15.0%±0.5% at the end of year 2. Median time to initiating therapy was 300 days. Using a Cox regression analysis, positive predictors of treatment initiation included age (hazard ratio, 1.008), prior hepatitis C virus treatment (1.74), cirrhosis (2.64), and history of liver transplant (1.5). History of drug abuse (0.43), high baseline alanine aminotransferase levels (0.79), hepatitis B virus infection (0.41), and self-pay (0.39) were negatively associated with treatment initiation. In the evaluable population (n = 423), 83.9% (95% confidence interval, 80.1-87.3%) of people achieved sustained virologic response. In the early years of the direct-acting antiviral era, <10% of people diagnosed with chronic hepatitis C virus infection received direct-acting antiviral treatment; median time to treatment initiation was 300 days. Future analyses should evaluate time to treatment initiation among those with less advanced fibrosis.
Pembrolizumab plus concurrent chemoradiotherapy versus placebo plus concurrent chemoradiotherapy in patients with locally advanced squamous cell carcinoma of the head and neck (KEYNOTE-412): a randomised, double-blind, phase 3 trial
Despite multimodal therapy, 5-year overall survival for locally advanced head and neck squamous cell carcinoma (HNSCC) is about 50%. We assessed the addition of pembrolizumab to concurrent chemoradiotherapy for locally advanced HNSCC. In the randomised, double-blind, phase 3 KEYNOTE-412 trial, participants with newly diagnosed, high-risk, unresected locally advanced HNSCC from 130 medical centres globally were randomly assigned (1:1) to pembrolizumab (200 mg) plus chemoradiotherapy or placebo plus chemoradiotherapy. Randomisation was done using an interactive response technology system and was stratified by investigator's choice of radiotherapy regimen, tumour site and p16 status, and disease stage, with participants randomly assigned in blocks of four per stratum. Participants, investigators, and sponsor personnel were masked to treatment assignments. Local pharmacists were aware of assignments to support treatment preparation. Pembrolizumab and placebo were administered intravenously once every 3 weeks for up to 17 doses (one before chemoradiotherapy, two during chemoradiotherapy, 14 as maintenance therapy). Chemoradiotherapy included cisplatin (100 mg/m2) administered intravenously once every 3 weeks for two or three doses and accelerated or standard fractionation radiotherapy (70 Gy delivered in 35 fractions). The primary endpoint was event-free survival analysed in all randomly assigned participants. Safety was analysed in all participants who received at least one dose of study treatment. This study is registered with ClinicalTrials.gov, NCT03040999, and is active but not recruiting. Between April 19, 2017, and May 2, 2019, 804 participants were randomly assigned to the pembrolizumab group (n=402) or the placebo group (n=402). 660 (82%) of 804 participants were male, 144 (18%) were female, and 622 (77%) were White. Median study follow-up was 47·7 months (IQR 42·1–52·3). Median event-free survival was not reached (95% CI 44·7 months–not reached) in the pembrolizumab group and 46·6 months (27·5–not reached) in the placebo group (hazard ratio 0·83 [95% CI 0·68–1·03]; log-rank p=0·043 [significance threshold, p≤0·024]). 367 (92%) of 398 participants treated in the pembrolizumab group and 352 (88%) of 398 participants treated in the placebo group had grade 3 or worse adverse events. The most common grade 3 or worse adverse events were decreased neutrophil count (108 [27%] of 398 participants in the pembrolizumab group vs 100 [25%] of 398 participants in the placebo group), stomatitis (80 [20%] vs 69 [17%]), anaemia (80 [20%] vs 61 [15%]), dysphagia (76 [19%] vs 62 [16%]), and decreased lymphocyte count (76 [19%] vs 81 [20%]). Serious adverse events occurred in 245 (62%) participants in the pembrolizumab group versus 197 (49%) participants in the placebo group, most commonly pneumonia (43 [11%] vs 25 [6%]), acute kidney injury (33 [8%] vs 30 [8%]), and febrile neutropenia (24 [6%] vs seven [2%]). Treatment-related adverse events led to death in four (1%) participants in the pembrolizumab group (one participant each from aspiration pneumonia, end-stage renal disease, pneumonia, and sclerosing cholangitis) and six (2%) participants in the placebo group (three participants from pharyngeal haemorrhage and one participant each from mouth haemorrhage, post-procedural haemorrhage, and sepsis). Pembrolizumab plus chemoradiotherapy did not significantly improve event-free survival compared with chemoradiotherapy alone in a molecularly unselected, locally advanced HNSCC population. No new safety signals were seen. Locally advanced HNSCC remains a challenging disease that requires better treatment approaches. Merck Sharp & Dohme, a subsidiary of Merck & Co, Rahway, NJ, USA.
