Pulmonary Ionocytes Regulate Airway Surface Liquid pH in Primary Human Bronchial Epithelial Cells.

Rationale: Pulmonary ionocytes are a newly discovered airway epithelial cell type proposed to be a major contributor to cystic fibrosis (CF) lung disease based on observations they express the cystic fibrosis transmembrane conductance regulator (CFTR) anion channel at a higher level than any other cell type in the airway epithelia. Moreover, genetically manipulated experimental models that lack ionocytes develop NaCl transport abnormalities and airway surface liquid (ASL) dehydration consistent with CF. However, no direct evidence indicates ionocytes engage in NaCl transport or contribute to ASL formation, questioning the relevance of ionocytes to CF lung disease. Objectives: To determine the ion transport properties of pulmonary ionocytes and club cells in genetically intact healthy and CF airway epithelia. Methods: We measured ion transport at the single-cell level using a self-referencing ion-selective microelectrode technique in primary human bronchial epithelial cell culture. Measurements and Main Results: cAMP-stimulated non-CF ionocytes do not secrete Na+ or Cl- into the ASL, but rather modulate its pH by secreting bicarbonate via CFTR-linked Cl-/bicarbonate exchange. Non-CF club cells secrete Na+ and Cl- to the lumen side after cAMP stimulation. CF ionocytes and club cells do not transport ions in response to cAMP stimulation, but incubation with CFTR modulators elexacaftor/tezacaftor/ivacaftor restores transport properties. Conclusions: We conclude that ionocytes do not contribute to ASL formation but regulate ASL pH. Club cells secrete the bulk of airway fluid. In CF, abnormal ionocyte and club cell function results in acidic and dehydrated ASL, causing reduced antimicrobial properties and mucociliary clearance.

Live imaging of microtubule organization, cell expansion, and intercellular space formation in Arabidopsis leaf spongy mesophyll cells.

Leaf spongy mesophyll cells form an interconnected network of branched cells and intercellular spaces to maximize the surface area available for light capture and photosynthetic gas exchange. To investigate the morphogenetic events leading to cell separation and branching in Arabidopsis thaliana, we used mesophyll-specific promoters to facilitate imaging of mesophyll cell shape and microtubule (MT) organization over multiple spatiotemporal scales without interference from the overlying epidermal cells. We show that cells enlarge by selective expansion of cell wall regions in contact with intercellular spaces. Cell-cell contacts remain relatively fixed in size, forming the termini of interconnecting branches. Surprisingly, classic schizogeny (de-adhesion of neighboring cells) is relatively infrequent, being related to the local topology of cell junctions during early expansion. Intercellular spaces cue the position of stable MT bundles, which in turn promote efficient dilation of intercellular spaces and cell branching. Our data provide insights into mesophyll morphogenesis and MT organization and lay the groundwork for future investigations.

Ethanolic extract from fruiting bodies of Cordyceps militaris HL8 exhibits cytotoxic activities against cancer cells, skin pathogenic yeasts, and postharvest pathogen Penicillium digitatum.

Cordyceps militaris is a well-known medicinal mushroom in Asian countries. This edible fungus has been widely exploited for traditional medicine and functional food production. C. militaris is a heterothallic fungus that requires both the mating-type loci, MAT1-1 and MAT1-2, for fruiting body formation. However, recent studies also indicated two groups of C. militaris, including monokaryotic strains carrying only MAT1-1 in their genomes and heterokaryotic strains harboring both MAT1-1 and MAT1-2. These strain groups are able to produce fruiting bodies under suitable cultivating conditions. In previous work, we showed that monokaryotic strains are more stable than heterokaryotic strains in fruiting body formation through successive culturing generations. In this study, we report a high cordycepin-producing monokaryotic C. militaris strain (HL8) collected in Vietnam. This strain could form normal fruiting bodies with high biological efficiency and contain a cordycepin content of 14.43 mg/g lyophilized fruiting body biomass. The ethanol extraction of the HL8 fruiting bodies resulted in a crude extract with a cordycepin content of 69.15 mg/g. Assays of cytotoxic activity on six human cancer cell lines showed that the extract inhibited the growth of all these cell lines with the IC50 values of 6.41-11.51 µg/mL. Notably, the extract significantly reduced cell proliferation and promoted apoptosis of breast cancer cells. Furthermore, the extract also exhibited strong antifungal activity against Malassezia skin yeasts and the citrus postharvest pathogen Penicillium digitatum. Our work provides a promising monokaryotic C. militaris strain as a bioresource for medicine, cosmetics, and fruit preservation.

Abundance of Colistin-Resistance Genes in Retail Meats in Vietnam.

The degree of contamination of retail meat with colistin-resistant bacteria and its potential contribution to dissemination within communities remains to be determined. Thus, we aimed to elucidate the contamination status of colistin-resistance genes, indicative of colistin-resistant bacteria, in retail meats in Vietnam. In total, 46 chicken and 49 pork meats from stores in Vietnam and Japan were examined. Multiplex real-time polymerase chain reaction with TaqMan probes was performed for detecting mcr-1, mcr-3, and Escherichia coli 16S rRNA. Colistin-resistant bacteria in meats were isolated using selective media. The minimum inhibitory concentrations of colistin were determined using the broth microdilution method. The results showed that 70.7% of chicken meats in Vietnam were contaminated with both mcr-1 and mcr-3. Meanwhile, mcr-1 and mcr-3 were detected in 15.9% and 40.9% of pork meat, respectively. Only mcr-3 was detected in 40% of chicken in Japan. In addition, mcr-1-harboring E. coli and mcr-3-harboring Aeromonas were isolated from chicken meats in Vietnam. Some of these isolates showed colistin resistance. These results showed that most retail meats were highly contaminated with colistin-resistance genes. Notably, our results suggest that mcr-3 is more prevalent in the contaminated samples compared with mcr-1.

Severity of Peripheral Infection Differentially Affects Brain Functions in Mice via Microglia-Dependent and -Independent Mechanisms.

Peripheral infection induces inflammation in peripheral tissues and the brain, impacting brain function. Glial cells are key players in this process. However, the effects of peripheral infection on glial activation and brain function remain unknown. Here, we showed that varying degrees of peripheral infection had different effects on the regulation of brain functions by microglia-dependent and -independent mechanisms. Acute mild infection (one-day LPS challenge: 1LPS) exacerbated middle cerebral artery occlusion (MCAO) injury, and severe infection (four-day LPS challenge: 4LPS) for one week suppressed it. MCAO injury was assessed by triphenyltetrazolium chloride staining. We observed early activation of microglia in the 1LPS and 4LPS groups. Depleting microglia with a colony-stimulating factor-1 receptor (CSF1R) antagonist had no effect on 1LPS-induced brain injury exacerbation but abolished 4LPS-induced protection, indicating microglial independence and dependence, respectively. Microglia-independent exacerbation caused by 1LPS involved peripheral immune cells including macrophages. RNA sequencing analysis of 4LPS-treated microglia revealed increased factors related to anti-inflammatory and neuronal tissue repair, suggesting their association with the protective effect. In conclusion, varying degrees of peripheral inflammation had contradictory effects (exacerbation vs. protection) on MCAO, which may be attributed to microglial dependence. Our findings highlight the significant impact of peripheral infection on brain function, particularly in relation to glial cells.

Assessing the Impact of a Patient Navigator Intervention Program for Vietnamese-American Women with Abnormal Mammograms.

Breast cancer incidence among Asian Americans increased at a rate of 1.8% per year from 2014 to 2018, while the general population's incidence rate remained stable. Vietnamese-American women have been found to have the longest follow-up time after an abnormal mammogram. This study assesses the impact of a patient navigator program for Vietnamese-American women who received abnormal mammograms. Ninety-six Vietnamese-American participants with abnormal mammograms were assigned a Vietnamese patient navigator to provide emotional support, education, translation, and assistance with medical bills and doctor's appointments. Data collected from pre-test, post-test (1 year after initial enrollment in program), and 3-month follow-up surveys measured psychosocial outcomes and participant satisfaction. All 96 participants attended follow-up appointments for their abnormal mammograms. Psychosocial outcomes worsened from pre- to post-test, though these results were not statistically significant. Feeling in control of situations in one's life improved and was significant for participants who did not receive a breast cancer diagnosis (4.31, 5.04, p = .039). A majority of the participants reported satisfaction with their patient navigators. Vietnamese-American women have been found to be the least adherent to appropriate follow-up after an abnormal mammogram; in this study, all 96 participants attended a follow-up appointment within 90 days. Findings did not show improvements in psychosocial outcomes. Past research suggests that sociocultural factors may be at play: the initial abnormal mammogram may have triggered fatalistic thoughts affecting the reactions of the participants, even though the abnormal mammogram did not result in a breast cancer diagnosis.

Short Meal-to-Bed Time Is a Predominant Risk Factor of Gastroesophageal Reflux Disease in Pregnancy.

BACKGROUND: Short meal-to-bed time (MTBT) has been reported to relate to gastroesophageal reflux disease (GERD), but evidence is lacking in pregnant women. We aimed to assess the characteristics of GERD and the association between MTBT and GERD during pregnancy. PATIENTS AND METHODS: A cross-sectional study was carried out on 400 pregnant women aged 18 years and older visiting the antenatal clinic of Gia-Dinh People's Hospital, Vietnam. GERD was defined as having troublesome heartburn and/or regurgitation at least once a week. Reflux-related insomnia was defined as having difficulties in initiating or maintaining sleep through the night. MTBT was defined as "short" if it was ≤2 hours in more than two thirds of days in a week. RESULTS: There were 154 (38.5%) patients with GERD and 20 (13.0%) patients with reflux-related insomnia. In multivariate analysis, there were 3 factors significantly associated with GERD: third trimester [odds ratio (OR)=1.66; 95% confidence interval (CI): 1.03-2.69], previous history of typical reflux symptoms (OR=9.05; 95% CI: 5.29-15.50), and short MTBT (OR=12.73; 95% CI: 2.92-55.45). The frequency of reflux symptoms progressively increased across subgroups of patients with no short MTBT, either daytime or nighttime short MTBT, and with both daytime and nighttime short MTBT. Nighttime MTBT was also a significant risk factor for reflux-related insomnia (OR=4.60; 95% CI: 1.64-12.92). CONCLUSIONS: We reported for the first time that short MTBT was a predominant risk factor of GERD in pregnancy. This dieting habit was significantly associated with reflux symptom frequency and reflux-related insomnia.

The evaluation of comprehensive medication management for chronic diseases in primary care clinics, a Texas delivery system reform incentive payment program.

BACKGROUND: The Institute of Medicine reported that more than 1.5 million preventable adverse drug events occur annually in the United States. Comprehensive Medication Management (CMM) is the medication review process to improve clinical outcomes, enhance patient adherence, reduce drug therapy problems and reduce health care costs. University of Texas (UT) Physicians implemented a CMM program in several community-based clinics. We evaluated the effectiveness of CMM to reduce drug therapy problems and achieve medical cost savings. METHODS: This was a retrospective, observational study of CMM participants from October 2015 to September 2016. Program participants included patients aged 18 years or older who had taken more than 4 prescribed medications and were diagnosed with at least one of the following chronic diseases: hypertension, congestive heart failure, chronic obstructive pulmonary disease, asthma or diabetes. Under the CMM program, a clinical pharmacist reviewed patients' electronic health records and created action plans to resolve identified drug problems. As part of the evaluation of the clinical process, two independent physicians conducted peer review on the recommendations issued by the pharmacist in order to establish inter-rater reliability of drug therapy problems and potential consequent medical services. The drug therapy problems were identified and classified into four categories: indication, effectiveness, safety and/or compliance. The average cost of avoided medical services was obtained based on cost extrapolations from the literature, combined with hospital discharge data. Potential medical services avoided were linked to the average cost of those services to calculate the total cost savings of the program from the payers' perspective. RESULTS: By reviewing electronic health records of 3280 patients, the pharmacist identified 301 drug therapy problems and resolved 49.8% of these problems with collaboration from the patient's primary care physician or care team. The most commonly identified drug problems were related to potentially adverse drug reactions or inappropriate drug dosage. The CMM program resulted in potential cost savings of $1,143,015. CONCLUSIONS: The CMM program resolved medication therapy problems among program participants and achieved significant health care cost savings.

Postoperative Pain Management among Registered Nurses in a Vietnamese Hospital.

This study examined the postoperative pain management practices among registered nurses in an urban hospital in Vietnam. Data of 90 nurses about postoperative pain management practices and pain management at the department were collected. Results indicated that 83.3% of nurses reported that they regularly assessed the degree of pain for postoperative patients. Only 32.2% used assessment tools such as the numeric rating scale to measure pain. Experience in pain management and having guidelines in the department were associated with a higher score in pain management practice. Findings suggested that facilitating the use of pain instruments and developing pain management guidelines should be prioritized.

Suc Khoe là Hanh Phúc (Health is Happiness): promoting mammography and pap test adherence among Vietnamese nail salon workers.

Vietnamese nail salon workers have low cancer screening rates and confront multiple socioeconomic disparities as immigrants to the US. The Suc Khoe là Hanh Phúc (Vietnamese for "Health is Happiness") program was adapted to the cultural and work needs of this population and implemented at nail salons to increase cancer screening adherence. A total of 186 study participants were recruited from 59 nail salons in a neighborhood with mostly Asian population. After being pretested, workers were enrolled in a cancer education session delivered by Vietnamese lay health workers. Non-adherent cases were offered navigation to cancer screening services to a local federally qualified health center. Participants completed a posttest survey five months, on average. At posttest, navigated non-adherent participants were more likely to report a recent Pap test compared to cases not navigated (83.8% vs. 50.0%), an effect not observed for mammography uptake (77.3% vs. 71.4%). Time in the US, marital status, insurance status, having a primary care provider and/or a gynecologist were significantly associated with cancer screening adherence. Low rates of adherence to cancer screening among Vietnamese nail salons workers can be improved by community based programs addressing cultural and work-related barriers confronted by this population.

Correlates of Treatment Readiness among Formerly Incarcerated Homeless Women.

Treatment readiness is a key predictor of drug treatment completion, rearrest, and recidivism during community reentry; however, limited data exists among homeless, female ex-offenders (HFOs). The purpose of this study was to present baseline data from a randomized controlled trial of 130 HFOs who had been released from jail or prison. Over half (60.8%) of HFOs had a treatment readiness score of ≥ 40 (n = 79, µ = 40.2, SD = 8.72). Bivariate analyses revealed that methamphetamine use, psychological well-being, and high emotional support were positively associated with treatment readiness. On the other hand, depressive symptomology and depression/anxiety scores were negatively associated with the treatment readiness score. Multiple linear regression revealed that depressive symptomology was negatively associated with treatment readiness (ß = -0.377; p = .001). Further analyses revealed that the effect of emotional support on treatment readiness was mediated by depressive symptomatology.

Pretreatment HIV-1 drug resistance to first-line drugs: results from a baseline assessment of a large cohort initiating ART in Vietnam, 2009-10.

OBJECTIVES: The objective of this study was to determine the prevalence and correlates of pretreatment drug resistance (PDR) to first-line antiretroviral drugs among people initiating therapy for HIV in Vietnam. METHODS: Blood was collected during November 2009 to October 2010 from people consecutively initiating ART in four purposively selected public outpatient clinics in three Vietnamese cities. At each study site, recruitment lasted for 6-10 months until the target sample size (range 120-130 individuals) had been reached. The viral load was measured in 501 samples; 490 samples (viral load ≥1000 copies/mL) were genotyped using a nucleotide population-based sequencing assay. Self-reported demographic and clinical data were elicited through interviews. We classified drug-resistance-associated mutations (DRMs) according to the 2009 WHO surveillance list. RESULTS: DRMs were identified in 17/490 participants (3.5%; 95% CI 2.2%-5.5%). The prevalence of DRMs was 1.6% (8/490) against NRTIs, 1.6% (8/490) against NNRTIs and 0.8% (4/490) against PIs; three (0.6%) participants were resistant to both NRTIs and NNRTIs. The overall prevalence of PDR to first-line drugs was low [2.7% (13/490); 95% CI 1.6%-4.4%]. The prevalence of PDR to first-line drugs was greater among 198 HIV-infected participants who injected drugs than among 286 participants who reported risks for sexually acquired HIV (4.0% versus 1.4%, P = 0.079). Multivariable logistic regression analysis suggested that PDR to first-line drugs was significantly higher among people who injected drugs (OR = 3.94; 95% CI 1.13-13.68). CONCLUSIONS: With low PDR, first-line ART may be effective in Vietnam and pretreatment genotyping may be unnecessary. Continuing strategies for the prevention and surveillance of antiretroviral resistance are important for maintaining a low prevalence of antiretroviral resistance in Vietnam. The association between resistance and injection drug use warrants further research.

Treatment decisions for localized prostate cancer: a concept mapping approach.

OBJECTIVE: Few decision aids emphasize active surveillance (AS) for localized prostate cancer. Concept mapping was used to produce a conceptual framework incorporating AS and treatment. METHODS: Fifty-four statements about what men need to make a decision for localized prostate cancer were derived from focus groups with African American, Latino and white men previously screened for prostate cancer and partners (n = 80). In the second phase, 89 participants sorted and rated the importance of statements. RESULTS: An eight cluster map was produced for the overall sample. Clusters were labelled Doctor-patient exchange, Big picture comparisons, Weighing the options, Seeking and using information, Spirituality and inner strength, Related to active treatment, Side-effects and Family concerns. A major division was between medical and home-based clusters. Ethnic groups and genders had similar sorting, but some variation in importance. Latinos rated Big picture comparisons as less important. African Americans saw Spirituality and inner strength most important, followed by Latinos, then whites. Ethnic- and gender-specific concept maps were not analysed because of high similarity in their sorting patterns. CONCLUSIONS: We identified a conceptual framework for management of early-stage prostate cancer that included coverage of AS. Eliciting the conceptual framework is an important step in constructing decision aids which will address gaps related to AS.

Designing Normative Messages About Active Surveillance for Men With Localized Prostate Cancer.

Active surveillance is increasingly recognized as a reasonable option for men with low-risk, localized prostate cancer, yet few men who might benefit from conservative management receive it. The authors examined the acceptability of normative messages about active surveillance as a management option for patients with low-risk prostate cancer. Men with a diagnosis of localized prostate cancer who were recruited through prostate cancer support organizations completed a web-based survey (N = 331). They rated messages about active surveillance for believability, accuracy, and importance for men to hear when making treatment decisions. The message "You don't have to panic … you have time to think about your options" was perceived as believable, accurate, and important by more than 80% of the survivors. In contrast, messages about trust in the active surveillance protocol and "knowing in plenty of time" if treatment is needed were rated as accurate by only about 36% of respondents. For active surveillance to be viewed as a reasonable alternative, men will need reassurance that following an active surveillance protocol is likely to allow time for curative treatment if the cancer progresses.

'It's not like you just had a heart attack': decision-making about active surveillance by men with localized prostate cancer.

BACKGROUND: Growing recognition that active surveillance (AS) is a reasonable management option for many men diagnosed with localized prostate cancer led us to describe patients' conceptualizations of AS and reasons for their treatment decisions. METHODS: Men were patients of a multidisciplinary prostate cancer clinic at a large tertiary cancer center where patients are routinely briefed on treatment options, including AS. We conducted a thematic analysis of interviews with 15 men who had chosen AS and 15 men who received radiation or surgery. RESULTS: Men who chose AS described it as an organized process with a rigorous and reassuring protocol of periodic testing, with potential for subsequent and timely decision-making about treatment. AS was seen as prolonging their current good health and function with treatment still possible later. Rationales for choosing AS included trusting their physician's monitoring, 'buying time' without experiencing adverse effects of treatment, waiting for better treatments, and seeing their cancer as very low risk. Men recognized the need to justify their choice to others because it seemed contrary to the impulse to immediately treat cancer. Descriptions of AS by men who chose surgery or radiation were less specific about the testing regimen. Getting rid of the cancer and having a cure were paramount for them. CONCLUSIONS: Men fully informed of their treatment options for localized prostate cancer have a comprehensive understanding of the purpose of AS. Slowing the decision-making process may enhance the acceptability of AS.

Knowledge, attitudes, and beliefs about human papillomavirus (HPV) vaccination among Puerto Rican mothers and daughters, 2010: a qualitative study.

INTRODUCTION: The incidence of human papillomavirus (HPV) infection and cervical cancer can be reduced by increasing vaccination for HPV. Yet vaccination uptake and completion of the 3-dose series remain low among Puerto Rican females. This study explored psychosocial factors associated with HPV vaccination uptake decisions among Puerto Rican mothers and daughters. METHODS: We conducted 7 focus groups with young women aged 16 to 24 (n = 21) and their mothers (n = 9) to assess knowledge, attitudes, and beliefs related to cervical cancer, HPV, and HPV vaccination. We analyzed the focus group transcripts and identified themes by using a constant comparison method of qualitative data analysis and interpretation, guided by a grounded theory approach. RESULTS: The analysis identified several emergent themes related to vaccine uptake: 1) low knowledge about cervical cancer, HPV, and the HPV vaccine; 2) inconsistent beliefs about susceptibility to HPV infection and cervical cancer; 3) vaccine effectiveness; 4) vaccine safety and side effects; 5) concerns that the vaccine promotes sexual disinhibition; and 6) availability of insurance coverage and overall cost of the vaccine. CONCLUSION: Our study found that adolescent girls and young women in Puerto Rico have low levels of knowledge about HPV and cervical cancer, low perceived susceptibility to HPV, and concerns about the safety and efficacy of the vaccine, and these factors may influence uptake and completion of HPV vaccination. Interventions are needed for both mothers and daughters that address these psychosocial factors and increase access to vaccination.

Facilitators to cervical cancer screening in a minority, urban, underserved population.

Objectives: Cervical cancer has markedly declined due to widespread use of screening, but Hispanic women continue to bear a disproportionate amount of the cervical cancer burden due to under-screening. Previous studies have explored barriers to screening but have failed to identify targetable facilitators in this group. We aimed to assess facilitators to cervical cancer screening among a predominantly urban, Hispanic population who presented to a no-cost, community-based clinic. Methods: Patients completed demographic and health information, a validated social determinants of health (SDOH) screen, and a self-reported facilitators survey on factors which enabled them to present to clinic. Descriptive statistics were conducted to assess patients' sociodemographic characteristics, SDOH, and perceived facilitators. Results: 124 patients were included. 98 % were Hispanic, 90 % identified Spanish as their preferred language, and 94 % had no insurance. Median age was 41. 31 % of patients reported a history of abnormal screening. On SDOH, over 80 % of patients screened positive in at least one domain, with the most common being food insecurity (53 %) and stress (46 %). The most frequently reported facilitator was encouragement from a family member/friend (30 %). 26 % of patients reported time off from work and 25 % reported availability of child/elder care as facilitators. Conclusions: Identifying facilitators among patients who present for cervical cancer screening is critical to designing care plans to reach all populations. Our survey showed that the single greatest facilitator to patients presenting for cervical cancer screening was encouragement from a family member/friend. These findings suggest that increasing community involvement and awareness may help to improve cervical cancer screening in a minority, urban, underserved population.

Evaluation of a Clinic-Based, Electronic Social Determinants of Health Screening and Intervention in Primary Care Pediatrics.

OBJECTIVE: Social determinants of health (SDOH) significantly affect individuals' health outcomes, yet universal electronic SDOH screening is not standard in primary care. Our study explores the implementation of an electronic SDOH screening in the electronic health record (EHR) and follow-up intervention among primary care pediatric patients within an academic clinic. METHODS: Beginning in August of 2022, patients and their families determined to have at least one SDOH need qualified for an in-clinic referral to a coordinated care team member. We assessed the overall efficacy and feasibility of the implementation. RESULTS: Over the 4-month pilot, 1473 of 2064 (71.4%) eligible patients were screened, with 472 (32%) patients screening positive on at least one SDOH domain. Of the 472 screened positive, 48 (10.2%) declined a referral. Two hundred and forty-seven of the 424 (58.3%) received a referral to a care coordination team member. CONCLUSIONS: This study demonstrates the feasibility of a universal electronic SDOH screening tool within the EHR within an urban, academic-based clinic.

English proficiency, knowledge, and receipt of HPV vaccine in Vietnamese-American women.

Cervical cancer is one of the most important disease burdens experienced by Vietnamese-American women. Human papillomavirus (HPV) is the etiological agent in almost all cases of cervical cancer. We surveyed Vietnamese-American women to determine receipt of HPV vaccine and assessed if limited English proficiency and knowledge related to HPV vaccine were associated with HPV vaccine uptake. Of the 113 Vietnamese-American women who participated in the study, 58 % (n = 68) was born in Vietnam. The mean years of residency in the United States was 12.75 years. Only 16 (14 %) reported receiving HPV vaccine and 11 (9 %) reported receiving all three shots. Thirteen women responded that they are not at all likely to receive HPV vaccine. Of the whole sample, 47 % (n = 53) reported proficiency in spoken and written English. English proficiency was significantly associated with receipt of HPV vaccine (OR = 4.4; confidence interval (95 % CI) = 1.2; 16.50; p = 0.03). Of the knowledge items, 70 % (n = 79) responded correctly that HPV increases the risk for cervical cancer. However, as many as 60 % responded incorrectly, that HPV infection can be cured with medication. The item, "People infected with HPV can be cured with medication," was the most important variable associated with receipt of HPV vaccine. Specifically, those with correct response were 3.8 times more likely to report receiving the HPV vaccine (OR = 3.8; 95 % CI = 1.1; 13.5; p = 0.04). Important public health needs are the development and evaluation of educational programs on HPV and cervical cancer that are designed for Vietnamese-American women.

A validation study of PHQ-9 suicide item with the Columbia Suicide Severity Rating Scale in outpatients with mood disorders at National Network of Depression Centers.

BACKGROUND: In the United States, suicide is one of the serious public health problems and a major cause of death. Several researchers and clinical settings use the patient health questionnaires (PHQ-9) to gauge depression and psychological distress among adults and to predict suicide and death. This study aimed to assess the sensitivity, specificity, and predictive potential of suicide Q9 of the PHQ-9 compared to the Columbia-suicide severity rating scale (C-SSRS). METHODS: Adults aged 19 or older, identified with a primary mood disorder diagnosis during their initial clinic visit between 2012 and 2020 from the National Network of Depression Centers, were included in the study. The accuracy of the PHQ-9 suicide item was compared with the gold standard, the C-SSRS. RESULTS: Out of 2677 study participants, 31.6 % (n = 846) and 11.65 % (n = 312) had positive responses to the PHQ-9 suicide item and C-SSRS response, respectively. The sensitivity of the PHQ-9 compared to the C-SSR was 74.7 % (95%CI: 69.6 %-79.2 %), specificity 74.1 % (95%CI: 72.3 %-75.8 %), positive predictive value 27.5 % (95%CI: 24.6 %-30.6 %), and negative predictive value 95.7 % (95%CI: 94.7 %-96.5 %). The secondary analysis results showed better validity results of the PHQ-9 suicide item when compared to the suicide ideation item of the C-SSRS. LIMITATIONS: This study is among mood disorder patients so additional research would be necessary among populations with different conditions. CONCLUSION: For initial suicide screening, the PHQ-9 suicide item would over identify patients as at risk for suicide and the C-SSRS should be used mood disorder clinics to identify suicide risk.
