Background:
Hearing loss (HL) is one of the most common sensory disorders,
affecting over 5-8% of the world's population. Approximately half of HL cases are
attributed to genetic factors. In hereditary deafness, about 75-80% is inherited
through autosomal recessive inheritance, and common pathogenic genes include
GJB2 and SLC26A4. Pathogenic variants in the SLC26A4gene are the leading
cause of hereditary hearing loss in humans, second only to the GJB2 gene. Variants in the SLC26A4gene cause hearing loss, which can be non-syndromic autosomal recessive deafness (DFNB4, OMIM #600791) associated with enlarged
vestibular aqueduct (EVA) or Pendred syndrome (Pendred, OMIM #605646).
DFNB4 is characterized by sensorineural hearing loss combined with EVA or less
common cochlear malformation defect. Pendred syndrome is characterized by bilateral sensorineural hearing loss with EVA and an iodine defect that can lead to
thyroid goiter. Currently, it is known that EVA is associated with variants in the
SLC26A4 gene and is a penetrant feature of SLC26A4-related HL. Predominant
mutations in these genes differ significantly across populations. For instance, predominant SLC26A4 mutations differ among populations, including p.T416P and
c.1001G>A in Caucasians, p.H723R in Japanese and Koreans, and c.919-2A>G
in Han Taiwanese and Han Chinese. On the other hand, there has been no study
of hearing loss related to SLC26A4 gene variants among Mongolians, which is the
basis of our research.
Aim:
We aimed to identify the characteristics of the SLC26A4 gene variants in
Mongolian people with Enlarged vestibular aqueduct and Mondini malformation.
Materials and Methods:
In 2022-2024, We included 13 people with hearing loss
and enlarged vestibular aqueduct, incomplete cochlea (1.5 turns of the cochlea
with cystic apex- incomplete partition type II- Mondini malformation) were examined by CT scan of the temporal bone in our study. WES (Whole exome sequencing) analysis was performed in the Genetics genetic-laboratory of the National
Taiwan University Hospital.
Results:
Genetic analysis revealed 26 confirmed pathogenic variants of bi-allelic
SLC26A4 gene of 8 different types in 13 cases, and c.919-2A>G variant was dominant with 46% (12/26) in allele frequency, and c.2027T>A (p.L676Q) variant 19%
(5/26), c.1318A>T(p.K440X) variant 11% (3/26), c.1229C>T (p.T410M) variant 8%
(2/26) ) , c.716T>A (p.V239D), c.281C>T (p.T94I), c.1546dupC, and c.1975G>C
(p.V659L) variants were each 4% (1/26)- revealed. Two male children, 11 years
old (SLC26A4: c.919-2A>G) and 7 years old (SLC26A4: c.919-2A>G:, SLC26A4:
c.2027T>A (p.L676Q))had history of born normal hearing and progressive hearing
loss.
Conclusions
1. 26 variants of bi-allelic SLC26A4 gene mutation were detected
in Mongolian people with EVA and Mondini malformation, and c.919-2A>G was
the most dominant allele variant, and rare variants such as c.1546dupC, c.716T>A
(p.V239D) were detected.
2. Our study shows that whole-exome sequencing (WES) can identify gene
mutations that are not detected by polymerase chain reaction (PCR) or NGS analysis.

Background/Aims:
Systemic Inflammation (SI) is considered a key mechanism in disease progression and development of complications in decompensated liver cirrhosis. SI is mainly driven by portal hypertension and bacterial translocation. Transjugular intrahepatic portosystemic shunt (TIPS) insertion represents an effective treatment for portal hypertension. This study aims to investigate the impact of TIPS insertion on SI and bacterial translocation.
Methods:
We prospectively included 59 cirrhotic patients undergoing TIPS insertion. Blood samples were collected at TIPS insertion and follow-up (FU) 1, 3, 6, and 12 months thereafter. At all time points, we performed a comprehensive analysis of SI including 43 soluble inflammatory markers (SIMs), and surrogates of bacterial translocation (sCD14, sCD163). To investigate long-term kinetics of SI, C-reactive protein (CRP) and white blood cells (WBC) were retrospectively analyzed in a cohort of 177 patients up to 3 years after TIPS insertion.
Results:
At TIPS insertion, 30/43 SIMs, sCD14, and sCD163 measured significantly higher in cirrhotic patients compared to healthy controls. By FU6 25 SIMs and sCD14 measured at significantly lower levels compared to baseline. Interestingly, in patients with TIPS indication of refractory ascites, IL-6 decreased to levels documented in earlier stages of cirrhosis. In long-term follow-up, CRP levels significantly decreased after TIPS insertion, which translated into lower mortality in Cox regression analysis (HR 0.968, p=0.042). Notably, patients with residual ascites post-TIPS showed significantly higher CRP and IL-6 levels across all follow-ups compared to patients with resolved ascites.
Conclusions
Decreasing portal hypertension via TIPS insertion leads to a significant attenuation of SI and bacterial translocation over time.

BACKGROUND AND OBJECTIVES
Among patients with macrovascular and microvascular disease, we investigated the association between sulodexide and cardiovascular (CV) outcomes and adverse events.
METHODSWe conducted a meta-analysis of randomized control trials (RCTs) reporting CV outcomes and adverse events in patients with vascular disease receiving sulodexide for any indication versus control. The following outcomes were investigated: any CV event, myocardial infarction, CV death, bleeding events and gastrointestinal symptoms.
RESULTSTwelve studies with a total of 8,436 patients were included. Sulodexide resulted in a significant reduction in CV events (OR 0.51 [95% confidence interval 0.41-0.73]; pCONCLUSION
Sulodexide has a beneficial effect among patients with macrovascular disease in terms of reducing the risk for MI, overall CV mortality and CV events. Larger RCTs are needed to corroborate these findings.

Purpose:
Patients with cancer are particularly vulnerable to coronavirus disease (COVID). Transportation barriers made travel to obtain medical care more difficult during the pandemic. Whether these factors led to changes in the distance traveled for radiotherapy and the coordinated location of radiation treatment is unknown.
Materials and Methods:
We analyzed patients across 60 cancer sites in the National Cancer Database from 2018 to 2020. Demographic and clinical variables were analyzed for changes in distance traveled for radiotherapy. We designated the facilities in the 99th percentile or above in terms of the proportion of patients who traveled more than 200 miles as “destination facilities.” We defined “coordinated care” as undergoing radiotherapy at the same facility where the cancer was diagnosed.
Results:
We evaluated 1,151,954 patients. There was a greater than 1% decrease in the proportion of patients treated in the Mid-Atlantic States. Mean distance traveled from place of residence to radiation treatment decreased from 28.6 to 25.9 miles, and the proportion traveling greater than 50 miles decreased from 7.7% to 7.1%. At “destination facilities,” the proportion traveling more than 200 miles decreased from 29.3% in 2018 to 24% in 2020. In comparison, at the other hospitals, the proportion traveling more than 200 miles decreased from 1.07% to 0.97%. In 2020, residing in a rural area resulted in a lower odds of having coordinated care (multivariable odds ratio = 0.89; 95% confidence interval, 0.83–0.95).
Conclusion
The first year of the COVID pandemic measurably impacted the location of U.S. radiation therapy treatment.

Indolylarylsulfones (IASs) are classical HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs) with a unique scaffold and possess potent antiviral activity. To address the high cytotoxicity and improve safety profiles of IASs, we introduced various sulfonamide groups linked by alkyl diamine chain to explore the entrance channel of non-nucleoside inhibitors binding pocket. 48 compounds were designed and synthesized to evaluate their anti-HIV-1 activities and reverse transcriptase inhibition activities. Especially, compound R10L4 was endowed with significant inhibitory activity towards wild-type HIV-1 (EC50(WT) = 0.007 μmol/L, SI = 30,930) as well as a panel of single-mutant strains exemplified by L100I (EC50 = 0.017 μmol/L, SI = 13,055), E138K (EC50 = 0.017 μmol/L, SI = 13,123) and Y181C (EC50 = 0.045 μmol/L, SI = 4753) which were superior to Nevirapine and Etravirine. Notably, R10L4 was characterized with significantly reduced cytotoxicity (CC50 = 216.51 μmol/L) and showed no remarkable in vivo toxic effects (acute and subacute toxicity). Moreover, the computer-based docking study was also employed to characterize the binding mode between R10L4 and HIV-1 RT. Additionally, R10L4 presented an acceptable pharmacokinetic profile. Collectively, these results deliver precious insights for next optimization and indicate that the sulfonamide IAS derivatives are promising NNRTIs for further development.
