Article Synopsis
  • This study investigates a new, minimally invasive technique for implanting spinal cord stimulation (SCS) paddle leads using a biportal endoscope and shares early clinical results.
  • Six patients underwent the procedure from February 2022 to December 2023, showing low blood loss (30 mL on average) and a reasonably quick operative time (87.5 minutes).
  • Results indicated significant pain reduction post-surgery, with most patients experiencing minimal complications, and the technique demonstrates promise for safely implementing SCS systems.

Ginger has been associated with a decreased incidence of colorectal cancer (CRC) through reduction in inflammatory pathways and inhibition of tumor growth. Recent pre-clinical models have implicated changes in the gut microbiome as a possible mediator of the ginger effect on CRC. We hypothesized that, in adults previously diagnosed with a colorectal adenoma, ginger supplementation would alter the fecal microbiome in the direction consistent with its CRC-inhibitory effect.

Background: It was hypothesized that governor vessel moxibustion (GVM) therapy may improve the course of mild to moderate psoriasis (PS) in patients.

Methods: A randomized, controlled clinical trial lasting 40 days was conducted at the Shaanxi Provincial Hospital of Chinese Medicine. Investigators were blinded to patient groupings.

Pharmacokinetic (PK) comparisons between therapeutic biologics have largely been based on the total area under the concentration-time curve (AUC) and the maximum concentration (C ). For biologics with a long half-life, a PK comparability study may be long in duration and costly to conduct. The goal of this study was to evaluate whether a truncated AUC (tAUC) can be used to assess PK comparability when bridging prefilled syringe (PFS) and autoinjector (AI) treatment options for biologics with a long half-life.

Article Synopsis
  • * Hmong participants (n=34) were given increasing doses of allopurinol, and a pharmacokinetic-pharmacodynamic analysis was performed to simulate personalized dosing based on their genetic makeup.
  • * The findings suggest that specific genotypes, alongside factors like body mass and kidney function, significantly affect oxypurinol clearance, helping tailor dosages for effective treatment while indicating that some genotypes may need alternative medications.

Background: Hmong men in Minnesota exhibit a high prevalence of gout and hyperuricemia. Although evidence of vitamin C's effectiveness as a treatment for gout is mixed, analysis of therapeutic benefit based on an individual's multiomic signature may identify predictive markers of treatment success.

Objectives: The primary objective of the Hmong Microbiome ANd Gout, Obesity, Vitamin C (HMANGO-C) study was to assess the effectiveness of vitamin C on serum urate in Hmong adults with and without gout/hyperuricemia.

Underrepresentation of subpopulations within geo-ancestral groups engaged in research can exacerbate health disparities and impair progress toward personalized medicine. This is particularly important when implementing pharmacogenomics which uses genomic-based sources of variability to guide medication selection and dosing. This mini-review focuses on pharmacogenomic findings with Hmong in the United States and their potential clinical implications.

Article Synopsis
  • The study aimed to assess incoming pharmacy doctoral students' knowledge and attitudes toward pharmacogenomics (PGx), as well as evaluate the reliability of a related PGx survey.
  • Results showed that while 91% of students recognized PGx as a useful tool for future practice, over 70% felt unconfident about their clinical PGx knowledge.
  • The survey identified that prior experiences with genetic testing and negative medication experiences were linked to more positive attitudes toward PGx among students.

Background Previous research predicted that Hmong, an understudied East Asian subpopulation, might require significantly lower warfarin doses than East Asian patients partially due to their unique genetic and clinical factors. However, such findings have not been corroborated using real-world data. Methods This was a retrospective cohort study of Hmong and East Asian patients receiving warfarin.

Hmong individuals represent a unique East Asian subpopulation in whom limited information concerning pharmacogenetic variation exists. The objectives of this study were to comprehensively characterize the highly polymorphic gene in Hmong, estimate allele and phenotype frequencies and to compare results between two testing platforms. DNA from 48 self-identified Hmong participants were sequenced using a targeted next-generation sequencing (NGS) panel.

Article Synopsis
  • Warfarin dosage is influenced by genetic factors, particularly in the Hmong population, which has been underrepresented in genetic research despite their distinct allele frequencies related to warfarin metabolism.
  • The study aims to validate these allele frequency differences in Hmong compared to East Asians and to analyze predicted warfarin sensitivity and maintenance doses.
  • Results show significant differences in allele frequencies for warfarin-related genes and indicate that Hmong individuals are more likely to be very sensitive to warfarin, requiring lower maintenance doses than their East Asian counterparts.*

Article Synopsis
  • The study aimed to explore how genetic differences in very important pharmacogenes (VIPs) among Hmong individuals could impact medication choices and dosages, comparing them with East Asians.
  • 194 Hmong adults' DNA was analyzed for 22 genetic variants in 8 VIPs, with significant allele frequency differences identified in 23% of the tested variants.
  • These genetic variations are likely to result in tailored medication recommendations for the Hmong population that differ from those suggested for East Asians, particularly for drugs like warfarin, simvastatin, and phenytoin.

Allopurinol, a common medication to treat gout, is associated with severe cutaneous adverse reactions, and the occurrence is highly predicted by an individual's HLA-B*58:01 carrier status. Guidelines endorse preemptive testing in select Asian populations before initiating allopurinol. The Hmong, an Asian subpopulation originally from China who now live dispersed around the world, have a 2.

Premise: (Cupressaceae) is a critically endangered conifer native to China, Laos, and Vietnam, with only a few populations remaining in the wild.

Methods And Results: Using a complete chloroplast genome sequence, we designed 70 cpSSR loci and tested them for amplification success and polymorphism in 16 samples. Ten loci were found to be polymorphic and their genetic diversity was characterized using a total of 83 individuals from three populations in China.

In this study, we applied metagenomic next-generation sequencing (mNGS) to detect the causative pathogens in brain abscess samples from 4 pediatric patients. NGS could offer unbiased sequencing and rapid diagnosis of causative pathogens, moreover, it could detect multiple pathogenic microorganisms from abscess samples. In our study, Fusobacterium nucleatum, and Streptococcus intermedius or combinations of them were found in 3/4 of polymicrobial brain abscesses.

Background: Pharmacist participation in school medication management (MM) is minimal. School nurses are responsible for increasingly complex medication administration and management in schools.

Objectives: The purpose of this study was to 1) assess the MM needs of school nurses in Minnesota, and 2) determine if and how interprofessional partnerships between nurses and pharmacists might optimize MM for students.

Background: Increasing rates of opioid-related deaths, state naloxone legislation changes, and negativity prompted investigation of predictive factors associated with willingness to prescribe naloxone to populations at risk of overdose, including knowledge of risk factors, assessment of persons at risk, awareness of legislative changes, perceptions of professional responsibility, and confidence around naloxone prescribing and distribution.

Methods: Cross-sectional, Web-based, anonymous, voluntary survey to prescribers of 2 regional health care systems serving urban and rural North Dakota, northern Minnesota, and northwestern Wisconsin. Human subject research was approved by university and health care systems' institutional review boards.
