Background:
s/Aims: Plasma pregenomic hepatitis B virus RNA (pgRNA) is a novel biomarker in chronic hepatitis B infection (CHB). We aimed to describe the longitudinal profile of pgRNA and factors influencing its levels in CHB patients on nucleoside analogue (NUC).
Methods:
Serial plasma samples from 1,354 CHB patients started on first-line NUC were evaluated. Time of NUC initiation was taken as baseline (year 0), followed by 1-year, 3-year and 5-year of NUC therapy. pgRNA was measured by Research Use Only RealTime HBV RNA v2.0 (0.2 mL) (Abbott Diagnostics) with lower limit of detection of 0.8 log U/mL (~20 copies/mL).
Results:
Among 1,354 subjects (median age at baseline 49.8 [interquartile range, IQR 40.2–57.3]) years, 65.2% male, 16.1% hepatitis B e antigen (HBeAg)-positive, 28.6% cirrhotic), baseline median HBV RNA was 3.68 (IQR 2.42–5.19) log U/mL. Upon NUC therapy, median pgRNA levels were 2.45 (IQR 1.82–3.62), 2.23 (IQR 1.67–3.05) and 2.14 (IQR 1.48–2.86) log U/mL at 1, 3 and 5 years, respectively, with the corresponding log U/mL reductions of 0.82, 1.20 and 1.54. Undetectable/ unquantifiable pgRNA was achieved in 13.5%, 15.9% and 20.1% of patients at 1, 3 and 5 years, respectively. Older age, male sex, HBeAg-negativity and high PAGE-B score were associated with lower pgRNA.
Conclusions
Plasma pgRNA declines are modest under NUC therapy, with only 16.3% achieving RNA undetectability after 5 years of first-line NUC indicating cccDNA silencing has not been achieved in the majority of patients. Clinical characteristics should be taken into consideration when interpreting the plasma pgRNA level.

Background:Low awareness of common pediatric eye conditions,such as amblyopia,conjunctivitis,and myopia in rural Chiang Rai,Thailand,prompted the development of a specialized curriculum.This curriculum aimed to provide individuals serving these areas with resources to educate and disseminate information within their communities.Methods:A one-hour curriculum covering the causes,signs,diagnosis,treatment,and prevention of amblyopia,conjunctivitis,and myopia was delivered virtually to public health students at a Thai university and in-person to students at this university and rural community members.The in-person seminar included hands-on activities and simulations of these eye conditions.Knowledge acquisition and retention were assessed using pre-tests,immediate post-tests,and one-month post-tests.Results:The seminar was attended by 87 virtual public health students,111 in-person public health students,and 40 in-person rural community members.All groups showed significant improvement in test scores from pre-test to immediate post-test(P<0.001).In-person students had 1.57 times the odds of answering correctly on the immediate post-test compared to virtual students,despite no significant difference in baseline knowledge.However,the subset of in-person students who did not receive bilingual materials showed no significant difference in immediate post-test performance compared to virtual students(P>0.05).Although public health students had more than twice the odds of answering correctly at pre-test compared to rural community members,there were no significant differences between groups on the immediate post-test(P>0.05).Conclusion:A brief seminar significantly improved understanding and retention of pediatric eye conditions,achieving similar levels of understanding among public health students and rural community members,regard-less of initial knowledge on this topic.In-person,hands-on seminars with educational materials in participants'preferred language proved more effective than virtual ones in achieving these improvements.

BACKGROUND
Broad Panel Respiratory Multiplex PCR (Pneumonia Panel) tests a panel of bacteria and viruses associated with community acquired pneumonia (CAP) which help streamline antimicrobial therapy. Recently, pneumonia panel aids clinicians in early streamlining of antimicrobials as opposed to waiting for bacterial culture results [2].
OBJECTIVETo determine whether the use of pneumonia panel improves the overall survival rate, length of hospital stay, and number of antibiotic free days among hospitalized CAP patients.
METHODOLOGYIn this RCT, adult patients admitted for CAP were randomized to perform pneumonia panel and sputum culture (pneumonia panel group) versus sputum culture only (control group). The results were relayed to the medical team and were incorporated into the medical records. Length of hospital stay, antibiotic free days in day 28, and mortality rates were the primary outcomes measured.
RESULTSEighty participants completed the study. There was no significant difference in the length of hospital stay (p-value 0.073, 95% C.I.), duration of antibiotic therapy (p-value 0.332, 95% C.I.), and mortality rates (p-value 0.570, 95% C.I.) between the 2 groups.
CONCLUSIONRoutine use of pneumonia panel does not significantly reduce length of hospital stay, duration of antibiotic therapy, and mortality rates among admitted patients with moderate to severe CAP. The benefit of pneumonia panel was seen on early detection of drug resistant pathogen resulting in early antibiotic escalation and shorter duration of antibiotic therapy. Further studies are necessary to show its benefit in the high risk population.

Purpose:
Prostate cancer (PCa) screening can lead to potential over-diagnosis/over-treatment of indolent cancers. There is a need to optimize practices to better risk-stratify patients. We examined initial longitudinal outcomes of mid-life men with an elevated baseline prostate-specific antigen (PSA) following initiation of a novel screening program within a system-wide network.
Materials and Methods:
We assessed our primary care network patients ages 40 to 49 years with a PSA measured following implementation of an electronic health record screening algorithm from 2/2/2017–2/21/2018. The multidisciplinary algorithm was developed taking factors including age, race, family history, and PSA into consideration to provide a personalized approach to urology referral to be used with shared decision-making. Outcomes of men with PSA ≥1.5 ng/mL were evaluated through 7/2021. Statistical analyses identified factors associated with PCa detection. Clinically significant PCa (csPCa) was defined as Gleason Grade Group (GGG) ≥2 or GGG1 with PSA ≥10 ng/mL.
Results:
The study cohort contained 564 patients, with 330 (58.5%) referred to urology for elevated PSA. Forty-nine (8.7%) underwent biopsy; of these, 20 (40.8%) returned with PCa. Eleven (2.0% of total cohort and 55% of PCa diagnoses) had csPCa. Early referral timing (odds ratio [OR], 4.58) and higher PSA (OR, 1.07) were significantly associated with PCa at biopsy on multivariable analysis (both p<0.05), while other risk factors were not. Referred patients had higher mean PSAs (2.97 vs. 1.98, p=0.001).
Conclusions
Preliminary outcomes following implementation of a multidisciplinary screening algorithm identified PCa in a small, important percentage of men in their forties. These results provide insight into baseline PSA measurement to provide early risk stratification and detection of csPCa in patients with otherwise extended life expectancy. Further follow-up is needed to possibly determine the prognostic significance of such mid-life screening and optimize primary care physician-urologist coordination.

Background:
Total shoulder arthroplasty (TSA) with a nonspherical humeral head component and inlay glenoid is a successful bone-preserving treatment for glenohumeral arthritis. This study aimed to describe the 90-day complication profile of TSA with this prosthesis and compare major and minor complication and readmission rates between inpatient- and outpatient-procedure patients.
Methods:
A retrospective review was performed of a consecutive cohort of patients undergoing TSA with a nonspherical humeral head and inlay glenoid in the inpatient and outpatient settings by a single surgeon between 2017 and 2022. Age, sex, body mass index, American Society of Anesthesiologists (ASA) score, Charlson Comorbidity Index (CCI), and 90-day complication and readmission rates were compared between inpatient and outpatient groups.
Results:
One hundred eighteen TSAs in 111 patients were identified. Mean age was 64.9 years (range, 39–90) and 65% of patients were male. Ninety-four (80%) and 24 (20%) patients underwent outpatient and inpatient procedures, respectively. Four complications (3.4%) were recorded: axillary nerve stretch injury, isolated ipsilateral arm deep venous thrombosis (DVT), ipsilateral arm DVT with pulmonary embolism requiring readmission, and gastrointestinal bleed requiring readmission. There were no reoperations or other complications. Outpatients were younger with lower ASA and CCI scores than inpatients; however, there was no difference in complications (1/24 vs. 3/94, P=1.00) or readmissions (1/24 vs. 1/94, P=0.37) between these two groups.
Conclusions
TSA with a nonspherical humeral head and inlay glenoid can be performed safely in both inpatient and outpatient settings. Rates of early complications and readmissions were low with no difference according to surgical setting.Level of evidence: IV.

Objective:
To describe the gene alteration status in high-grade neuroendocrine cervical carcinoma (NECC) specimens and to explore the potential association of unique gene alterations with survival.
Methods:
Results:
from tumor-based molecular testing on specimens from women with high-grade NECC in the Neuroendocrine Cervical Tumor Registry were reviewed and analyzed. Tumor specimens could be from primary or metastatic sites and obtained at initial diagnosis, during treatment, or at recurrence.
Results:
Molecular testing results were available for 109 women with high-grade NECC. The genes most frequently mutated were PIK3CA (mutated in 18.5% of patients), TP53 (17.4%), and MYC (14.5%). Other targetable alterations identified were alterations in KIT (7.3%), KRAS (7.3%), and PTEN (7.3%). Women with tumors having an RB1 alteration (6.4%) had a median overall survival (OS) of 13 months, compared to 26 months for women with tumors that did not have an RB1 alteration (p=0.003). None of the other genes evaluated were shown to be associated with OS.
Conclusion
Although no individual alteration was found in a majority of tumor specimens from patients with high-grade NECC, a large proportion of women with this disease will have at least one targetable alteration. Treatments based on these gene alterations may offer additional targeted therapies for women with recurrent disease, who currently have very limited therapeutic options. Patients with tumors that harbor RB1 alterations have decreased OS.
