Comparing Quality of Surgical Care Between the US Department of Veterans Affairs and Non-Veterans Affairs Settings: A Systematic Review.

In response to concerns about healthcare access and long wait times within the Veterans Health Administration (VA), Congress passed the Choice Act of 2014 and the Maintaining Internal Systems and Strengthening Integrated Outside Networks (MISSION) Act of 2018 to create a program for patients to receive care in non-VA sites of care, paid by VA. Questions remain about the quality of surgical care between these sites in specific and between VA and non-VA care in general. This review synthesizes recent evidence comparing surgical care between VA and non-VA delivered care across the domains of quality and safety, access, patient experience, and comparative cost/efficiency (2015 to 2021). Eighteen studies met the inclusion criteria. Of 13 studies reporting quality and safety outcomes, 11 reported that quality and safety of VA surgical care were as good as or better than non-VA sites of care. Six studies of access did not have a preponderance of evidence favoring care in either setting. One study of patient experience reported VA care as about equal to non-VA care. All 4 studies of cost/efficiency outcomes favored non-VA care. Based on limited data, these findings suggest that expanding eligibility for veterans to get care in the community may not provide benefits in terms of increasing access to surgical procedures, will not result in better quality, and may result in worse quality of care, but may reduce inpatient length of stay and perhaps cost less.

Disparities in telehealth access, not willingness to use services, likely explain rural telehealth disparities.

PURPOSE: Although telehealth access and utilization have increased during the pandemic, rural and low-income disparities persist. We sought to assess whether access or willingness to use telehealth differed between rural and non-rural and low-income and non-low-income adults and measure the prevalence of perceived barriers. METHODS: We conducted a cross-sectional study using COVID-19's Unequal Racial Burden (CURB) online survey (December 17, 2020-February 17, 2021), which included 2 nationally representative cohorts of rural and low-income Black/African American, Latino, and White adults. Non-rural and non-low-income participants from the main, nationally representative sample were matched for rural versus non-rural and low-income versus non-low-income comparisons. We measured perceived telehealth access, willingness to use telehealth, and perceived telehealth barriers. FINDINGS: Rural (38.6% vs 44.9%) and low-income adults (42.0% vs 47.4%) were less likely to report telehealth access, compared to non-rural and non-low-income counterparts. After adjustment, rural adults were still less likely to report telehealth access (adjusted prevalence ratio [aPR] = 0.89, 95% CI = 0.79-0.99); no differences were seen between low-income and non-low-income adults (aPR = 1.02, 95% CI = 0.88-1.17). The majority of adults reported willingness to use telehealth (rural = 78.4%; low-income = 79.0%), with no differences between rural and non-rural (aPR = 0.99, 95% CI = 0.92-1.08) or low-income versus non-low-income (aPR = 1.01, 95% CI = 0.91-1.13). No racial/ethnic differences were observed in willingness to use telehealth. The prevalence of perceived telehealth barriers was low, with the majority reporting no barriers (rural = 57.4%; low-income = 56.9%). CONCLUSIONS: Lack of access (and awareness of access) is likely a primary driver of disparities in rural telehealth use. Race/ethnicity was not associated with telehealth willingness, suggesting that equal utilization is possible once granted access.

Race/ethnicity-specific associations between breastfeeding information source and breastfeeding rates among U.S. women.

BACKGROUND: Despite evidence of the impact of breastfeeding information on breastfeeding rates, it is unknown if information sources and impact vary by race/ethnicity, thus this study assessed race/ethnicity-specific associations between breastfeeding information sources and breastfeeding. METHODS: We used data from the 2016-2019 Pregnancy Risk Assessment Monitoring System. Race/ethnicity-stratified multinomial logistic regression was used to estimate associations between information source (e.g., family/friends) and breastfeeding rates (0 weeks/none, < 10 weeks, or ≥ 10 weeks; < 10 weeks and ≥ 10 weeks = any breastfeeding). All analyses were weighted to be nationally representative. RESULTS: Among 5,945,018 women (weighted), 88% reported initiating breastfeeding (≥ 10 weeks = 70%). Information from family/friends (< 10 weeks: aORs = 1.58-2.14; ≥ 10 weeks: aORs = 1.63-2.64) and breastfeeding support groups (< 10 weeks: aORs = 1.31-1.76; ≥ 10 weeks: aORs = 1.42-2.77) were consistently associated with breastfeeding and duration across most racial/ethnic groups; effects were consistently smaller among Alaska Native, Black, and Hispanic women (vs White women). Over half of American Indian and one-quarter of Black women reported not breastfeeding/stopping breastfeeding due to return to school/work concerns. CONCLUSIONS: Associations between breastfeeding information source and breastfeeding rates vary across race/ethnicity. Culturally tailored breastfeeding information and support from family/friends and support groups could help reduce breastfeeding disparities. Additional measures are needed to address disparities related to concerns about return to work/school.

Impact of COVID-related policies on gunshot wound assault hospitalizations in the United States: a statewide time series analysis.

BACKGROUND: The CDC recently reported that firearm homicide rates in the United States increased in 2020, particularly among Black/African American individuals and men 25-44 years old. It is unclear whether firearm hospitalizations also increased, and more importantly, what impact the COVID-19 pandemic and COVID-related policies had. Using the North Carolina Trauma Registry, a statewide registry of trauma admissions to eighteen North Carolina hospitals, we calculated weekly GSW hospitalization rates from 1/2019 to 12/2020, overall and stratified by race-ethnicity, age, and sex. Interrupted time-series design and segmented linear regression were used to estimate changes in weekly hospitalization rates over time after (1) U.S. declaration of a public health emergency; (2) statewide Stay-at-Home order; (3) Stay-at-Home order lifted with restrictions (Phase 2: Safer-at-Home); and (4) further lifting of restrictions (Phase 2.5: Safer-at-Home). Non-GSW assault hospitalizations were used as a control to assess whether trends were observed across all assault hospitalizations or if effects were specific to gun violence. FINDINGS: Overall, 47.3% (n = 3223) of assault hospitalizations were GSW. Among GSW hospitalizations, median age was 27 years old (interquartile range [IQR] 21-25), 86.2% were male, and 49.5% occurred after the U.S. declared a public health emergency. After the Stay-at-Home order was implemented, weekly GSW hospitalization rates began increasing substantially among Black/African American residents (weekly trend change = 0.775, 95% CI = 0.254 to 1.296), peaking at an average 15.6 hospitalizations per 1,000,000 residents. Weekly hospitalization rates declined after restrictions were lifted but remained elevated compared to pre-COVID levels in this group (average weekly rate 10.6 per 1,000,000 at the end of 2020 vs. 8.9 per 1,000,000 pre-pandemic). The Stay-at-Home order was also associated with increasing GSW hospitalization rates among males 25-44 years old (weekly trend change = 1.202, 95% CI = 0.631 to 1.773); rates also remained elevated among 25-44-year-old males after restrictions were lifted in 2020 (average weekly rate 10.1 vs. 7.9 per 1,000,000). Non-GSW hospitalization rates were relatively stable in 2020. CONCLUSIONS: The COVID-19 pandemic and statewide Stay-at-Home orders appeared to have placed Black/African American residents and men ages 25-44 at higher risk for GSW hospitalizations, exacerbating pre-existing disparities. Persistent gun violence disparities must be addressed.

Current Postlaunch Implementation of State Mandates of Newborn Screening for Critical Congenital Heart Disease by Pulse Oximetry in U.S. States and Hospitals.

OBJECTIVE: Our objective was to gauge adherence to nationally endorsed protocols in implementation of pulse oximetry (POx) screening for critical congenital heart disease (CCHD) in infants after mandate by all states and to assess associated characteristics. STUDY DESIGN: Between March and October 2019, an online questionnaire was administered to nurse supervisors who oversee personnel conducting POx screening. The questionnaire used eight questions regarding performance and interpretation of screening protocols to measure policy consistency, which is adherence to nationally endorsed protocols for POx screening developed by professional medical societies. Multilevel linear regression models evaluated associations between policy consistency and characteristics of hospitals and individuals, state of hospital location, early versus late mandate adopters, and state reporting requirements. RESULTS: Responses from 189 nurse supervisors spanning 38 states were analyzed. Only 17% received maximum points indicating full policy consistency, and 24% selected all four options for potential hypoxia that require a repeat screen. Notably, 33% did not recognize ≤90% SpO2 as an immediate failed screen and 31% responded that an infant with SpO2 of 89% in one extremity will be rescreened by nurses in an hour rather than receiving an immediate physician referral. Lower policy consistency was associated with lack of state reporting mandates (beta = -1.23 p = 0.01) and early adoption by states (beta = -1.01, p < 0.01). CONCLUSION: When presented with SpO2 screening values on a questionnaire, a low percentage of nurse supervisors selected responses that demonstrated adherence to nationally endorsed protocols for CCHD screening. Most notably, almost one-third of respondents did not recognize ≤90% SpO2 as a failed screen that requires immediate physician follow-up. In addition, states without reporting mandates and early adopter states were associated with low policy consistency. Implementing state reporting requirements might increase policy consistency, but some inconsistency may be the result of unique protocols in early adopter states that differ from nationally endorsed protocols. KEY POINTS: · Low adherence to nationally endorsed protocols.. · Inconsistent physician follow-up to hypoxia.. · Reporting improved consistency with national policy..

Effect of Stay-at-Home orders and other COVID-related policies on trauma hospitalization rates and disparities in the USA: a statewide time-series analysis.

BACKGROUND: To combat the coronavirus pandemic, states implemented several public health policies to reduce infection and transmission. Increasing evidence suggests that these prevention strategies also have had a profound impact on non-COVID healthcare utilization. The goal of this study was to determine the impact of a statewide Stay-at-Home order and other COVID-related policies on trauma hospitalizations, stratified by race/ethnicity, age, and sex. METHODS: We used the North Carolina Trauma Registry, a statewide registry of trauma hospitalizations for 18 hospitals across North Carolina, including all North Carolina trauma centers, to calculate weekly rates of assault, self-inflicted, unintentional motor vehicle collision (MVC), and other unintentional injury hospitalizations between January 1, 2019, and December 31, 2020. Interrupted time-series design and segmented linear regression were used to estimate changes in hospitalization rates after several COVID-related executive orders, overall and stratified by race/ethnicity, age, and sex. Changes in hospitalization rates were assessed after 1) USA declaration of a public health emergency; 2) North Carolina statewide Stay-at-Home order; 3) Stay-at-Home order lifted with restrictions (Phase 2: Safer-at-Home); and 4) further lifting of restrictions (Phase 2.5: Safer-at-Home). RESULTS: There were 70,478 trauma hospitalizations in North Carolina, 2019-2020. In 2020, median age was 53 years old and 59% were male. Assault hospitalization rates (per 1,000,000 NC residents) increased after the Stay-at-Home order, but substantial increases were only observed among Black/African American residents (weekly trend change = 1.147, 95% CI = 0.634 to 1.662) and 18-44-year-old males (weekly trend change = 1.708, 95% CI = 0.870 to 2.545). After major restrictions were lifted, assault rates decreased but remained elevated compared to pre-COVID levels. Unintentional non-MVC injury hospitalizations decreased after the USA declared a public health emergency, especially among women ≥ 65 years old (weekly trend change = -4.010, 95% CI = -6.166 to -1.855), but returned to pre-pandemic levels within several months. CONCLUSIONS: Statewide Stay-at-Home orders placed Black/African American residents at higher risk of assault hospitalizations, exacerbating pre-existing disparities. Males 18-44 years old were also at higher risk of assault hospitalization. Fear of COVID-19 may have led to decreases in unintentional non-MVC hospitalization rates, particularly among older females. Policy makers must anticipate policy-related harms that may disproportionately affect already disadvantaged communities and develop mitigation approaches.

Unbiased approach to identify and assess efficacy of human SARS-CoV-2 neutralizing antibodies.

Coronavirus disease 2019 (COVID-19) continues to significantly impact the global population, thus countermeasure platforms that enable rapid development of therapeutics against variants of SARS-CoV-2 are essential. We report use of a phage display human antibody library approach to rapidly identify neutralizing antibodies (nAbs) against SARS-CoV-2. We demonstrate the binding and neutralization capability of two nAbs, STI-2020 and STI-5041, against the SARS-CoV-2 WA-1 strain as well as the Alpha and Beta variants. STI-2020 and STI-5041 were protective when administered intravenously or intranasally in the golden (Syrian) hamster model of COVID-19 challenged with the WA-1 strain or Beta variant. The ability to administer nAbs intravenously and intranasally may have important therapeutic implications and Phase 1 healthy subjects clinical trials are ongoing.

Effect of Stay-at-Home Orders and Other COVID-Related Policies on Trauma Hospitalization Rates and Disparities in the United States: A Statewide Time-Series Analysis.

Background: To combat the coronavirus pandemic, states implemented several public health policies to reduce infection and transmission. Increasing evidence suggests that these prevention strategies also have had a profound impact on non-COVID healthcare utilization. The goal of this study was to determine the impact of a statewide Stay-at-Home and other COVID-related policies on trauma hospitalizations, stratified by race/ethnicity, age, and sex. Methods: We used the North Carolina Trauma Registry, a statewide registry of trauma hospitalizations to 18 hospitals across North Carolina, including all North Carolina trauma centers, to calculate weekly assault, self-inflicted, unintentional motor vehicle collision (MVC), and other unintentional injury hospitalization rates between January 1, 2019 and December 31, 2020. Interrupted time-series design and segmented linear regression were used to estimate changes in hospitalizations rates after several COVID-related executive orders, overall and stratified by race/ethnicity, age, and gender. Hospitalization rates were compared after 1) U.S. declaration of a public health emergency; 2) North Carolina statewide Stay-at-Home order; 3) Stay-at-Home order lifted with restrictions (Phase 2: Safer-at-Home); and 4) further lifting of restrictions (Phase 2.5: Safer-at-Home). Results: There were 70,478 trauma hospitalizations in North Carolina from 2019-2020. In 2020, median age was 53 years old and 59% were male. Assault hospitalization rates (per 1,000,000 NC residents) increased after the Stay-at-Home order, but only among Black/African American residents (incidence rate difference [IRD]=7.9; other racial/ethnic groups' IRDs ranged 0.9 to 1.7) and 18-44 year-old males (IRD=11.9; other sex/age groups' IRDs ranged -0.5 to 3.6). After major restrictions were lifted, assault rates returned to pre-COVID levels. Unintentional injury hospitalizations decreased after the public health emergency, especially among older adults, but returned to 2019 levels within several months. Conclusions: Statewide Stay-at-Home orders put Black/African American residents at higher risk for assault hospitalizations, exacerbating pre-existing disparities. Fear of COVID-19 may have also led to decreases in unintentional non-MVC hospitalization rates, particularly among older adults. Policy makers must anticipate possible negative effects and develop approaches for mitigating harms that may disproportionately affect already disadvantaged communities.

Trauma Exposures, Resilience Factors, and Mental Health Outcomes in Persons Granted Asylum in the U.S. for Claims Related to Domestic Violence and Persecution by Organized Gangs.

Survivors of domestic violence (DV) and of violence perpetrated by organized gangs (GV) face barriers to legal protection under U.S. asylum law. We abstracted data from 132 affidavits based on forensic medical evaluations of asylum seekers granted legal protection in the U.S. on the basis of DV and/or GV. We described claimants' trauma exposures and resilience factors and used multiple logistic regression to quantify associations with Diagnostic and Statistical Manual-5 (DSM-5) diagnoses and improvement in mental health. People seeking asylum based on DV and/or GV have endured multiple types of trauma with significant impacts on their mental health. New experiences of trauma following migration to the U.S. were common and associated with DSM-5 diagnoses. Conversely, resilience factors were associated with improved mental health. Policies that aim to reduce ongoing trauma in the U.S. and to bolster resilience factors may promote asylee mental health and well-being.

Association of Race/Ethnicity with Surgical Route and Perioperative Outcomes of Hysterectomy for Leiomyomas.

STUDY OBJECTIVE: To evaluate the associations among race/ethnicity, route of surgery, and perioperative outcomes for women undergoing hysterectomy for uterine leiomyomas. DESIGN: Retrospective cohort study. SETTING: Multistate. PATIENTS: Women who underwent hysterectomies for leiomyomas from the American College of Surgeons National Surgical Quality Improvement Program database, 2014 to 2017. INTERVENTIONS: None. Exposures of interest were race/ethnicity and route of surgery. MEASUREMENTS AND MAIN RESULTS: Racial/ethnic variation in route of surgery and perioperative outcomes. Propensity score matching was employed to control for possible confounders. We identified 20 133 women who underwent nonemergent abdominal hysterectomy (AH), laparoscopic hysterectomy (LH), or vaginal hysterectomy (VH) for leiomyomas. We defined minimally invasive hysterectomy (MIH) as LH or VH. Black women were more likely to have open surgery (AH vs MIH adjusted odds ratio [aOR], 2.22; 95% confidence interval [CI], 2.07-2.38; AH vs VH aOR, 1.79; 95% CI, 1.54-2.08; AH vs LH aOR, 2.27; 95% CI, 2.13-2.44) than white women. Likewise, Hispanic women were more likely to have open surgery (AH vs MIH aOR, 1.76; 95% CI, 1.58-1.96; AH vs LH aOR, 1.82; 95% CI, 1.61-2.00) than white women. Black women were more likely to experience any complication after hysterectomy (AH aOR, 1.54; 95% CI, 1.31-1.80; VH aOR, 1.65; 95% CI, 1.02-2.68; LH aOR, 1.37; 95% CI, 1.13-1.66) than white women. Hispanic women were less likely than white women to experience major complications after VH (aOR, 0.28; 95% CI, 0.08-0.98). Compared with white women, the mean length of stay was longer for black women who underwent AH or LH. The mean total operation time was higher for all minority groups (except for Asian/other undergoing AH) regardless of surgical approach. CONCLUSION: Women of minority race/ethnicity were more likely to undergo abdominal rather than MIH for leiomyomas. Even when controlling for route of surgery, they were more likely to experience perioperative complications.

Association Between Human Papillomavirus Vaccination School-Entry Requirements and Vaccination Initiation.

Importance: Human papillomavirus (HPV) vaccination coverage is suboptimal in the US. The association between HPV vaccination requirements for school entry and HPV vaccination coverage remains to be studied. Objective: To examine the association between HPV vaccination school-entry requirements and vaccination initiation in jurisdictions with such vaccination policies (ie, Virginia, the District of Columbia, and Rhode Island) compared with other regions of the US, as determined by the National Center for Chronic Disease Prevention and Health Promotion. Design, Setting, and Participants: In a population-based, cross-sectional study, 2017 data from the National Immunization Survey-Teen database were used to determine HPV vaccination initiation. Data from 2008 to 2017 were then examined to assess the association between HPV vaccination school-entry policies and vaccination initiation. Data were obtained for adolescents aged 13 to 17 years in the US with health care professional-reported HPV vaccination histories (cross-sectional study, n = 4784; pre-post policy comparisons, n = 42 431). This study was conducted from May 1, 2019, to March 31, 2020. Exposures: State-level HPV vaccination school-entry requirements from 2008 to 2017. Main Outcomes and Measures: Health care professional-confirmed HPV vaccination initiation. Results: The 2017 cross-sectional study included 4784 adolescents aged 13 to 17 years (2228 [46.6%] girls; 2556 [53.4%] boys; mean [SD] age, 15.0 [1.4] years; interquartile range, 14-16 years). Compared with nonpolicy jurisdictions within the same region, Rhode Island and the District of Columbia, which have HPV immunization school-entry requirements, had higher levels of HPV vaccination initiation (Rhode Island: adjusted odds ratio [aOR], 4.34; 95% CI, 2.16-10.00; District of Columbia: aOR, 2.35; 95% CI, 1.39-4.19). However, compared with regional nonpolicy states, Virginia's HPV vaccination initiation did not differ significantly (aOR, 1.01; 95% CI, 0.72-1.42). The 2008-2017 pre-post policy comparisons involved 42 431 adolescents aged 13-17 years (22 362 [52.7%] girls; 20 069 [47.3%] boys; mean [SD] age, 15.0 [1.4] years; interquartile range, 14-16 years). Postpolicy levels of HPV vaccination initiation in girls was significantly higher in Rhode Island (aOR, 3.12; 95% CI, 1.92-5.07) than prepolicy values. Similar changes were noted for postpolicy HPV vaccination initiation in boys in the District of Columbia (aOR, 6.36; 95% CI, 4.27-9.46) and Rhode Island (aOR, 5.84; 95% CI, 3.92-8.69) compared with prepolicy measures. With respect to regional nonpolicy states during the same period, both girls and boys in Rhode Island and boys in the District of Columbia experienced larger increases in HPV vaccination initiation. For example, in Rhode Island, boys aged 16 to 17 years had 7.32 (95% CI, 3.56-15.06) times the change in pre-post policy HPV vaccination initiation, while girls aged 16 to 17 years had 1.28 (95% CI, 0.60-2.73) times the change. In the District of Columbia, boys had 6.36 (95% CI, 4.27-9.46) times the change in pre-post policy HPV vaccination initiation. Conclusions and Relevance: The findings of this study suggest that HPV vaccination school-entry requirements are associated with increases in vaccination initiation. Expanding such policies may increase HPV vaccination in the US.

Mobile health promotion of human immunodeficiency virus self-testing in the United States.

BACKGROUND: Human immunodeficiency virus (HIV) self-testing could overcome barriers associated with traditional HIV testing and increase people's awareness of their serostatus. Mobile health, which utilizes mobile wireless technology, could alleviate concerns associated with HIV self-testing and increase access to this screening test. METHODS: We conducted a PubMed, Google Scholar, and Google search to identify research studies and public health programs in the United States that used mobile health to provide HIV self-testing kits for participants. Nine research studies and two public health programs in the United States met the inclusion criteria and were included in the narrative review. RESULTS: Mobile health interventions delivered through online platforms and smartphone apps tailored towards high-risk populations could promote HIV self-testing distribution, pre- and post-test counseling, and linkage to follow-up care. CONCLUSIONS: Given mobile health's potential to encourage HIV self-testing, prevention, and treatment among high-risk communities, we included recommendations that incorporated this mode of HIV self-testing into public health programs to appropriately address the HIV epidemic in the United States.

Dietary patterns and thyroid cancer risk: a population-based case-control study.

PURPOSE: Thyroid cancer (TC) incidence has increased greatly during the past decades with a few established risk factors, while the relationship between dietary factors and TC remains unclear. Limited literature has investigated the association with inconsistent findings. METHODS: We examined the association between dietary pattern and risk of TC in a population based case-control study conducted in Connecticut (2010-2011). Our study population included 390 historically confirmed incident TC cases and 436 population-based controls who completed baseline dietary history questionnaires (DHQ). We identified 3 distinct dietary patterns ("Starchy Foods and Desserts", "Fruits and Vegetables", "High Protein and Fat") through principal components analysis. Multivariate unconditional logistic regression models were used to investigate the association between each dietary pattern and risk of TC, controlling for potential confounders. RESULTS: A diet rich in fruits and vegetables was significantly associated with a reduced risk of overall TC (OR = 0.60, 95% CI: 0.39, 0.92; P trend = 0.02). Compared to younger women, a stronger protective effect was observed among women ≥ 50 years of age in overall TC and papillary TC risk. A diet rich in starchy foods and desserts was positively and negatively associated with an overall TC risk among men and women respectively. CONCLUSIONS: Our study found a significant negative association between diet patterns rich in fruits and vegetables and TC risk, especially among women aged 50 years or older. While high in starchy foods and desserts may be positively and negatively associated with TC risk among men and women respectively, these results require confirmation in other populations.

Excess Cancer Cases and Medical Costs Due to Suboptimal Human Papillomavirus Vaccination Coverage in California.

BACKGROUND: Human papillomavirus (HPV) vaccination coverage continues to be at low to moderate levels throughout the United States. HPV infection is linked to multiple types of cancers resulting in high economic and health burden. We aimed to estimate the excess number of cancer cases and associated medical costs due to current HPV vaccination coverage for a 20-year-old birth cohort in California. METHODS: We estimated the lifetime number of cancer cases caused by vaccine-preventable strains of HPV for a cohort of 20 year-olds in California. We then estimated the excess number of cancer cases in that cohort which would occur due to 2017 HPV vaccination coverage compared with an optimal coverage of 99.5%. By multiplying those excess cases by the average cost of treatment, we determined the excess cost due to current HPV vaccination coverage. RESULTS: With current vaccination coverage in California, the 20-year-old cohort is at risk for an excess 1352 cancer cases that could be prevented with a projected optimal vaccination coverage of 99.5%. The excess cost of treatment for those cancer cases would be US $52.2 million. Male oropharyngeal cancer accounts for the greatest projected cost burden US $21.3 million followed by cervical cancer US $16.1 million. CONCLUSIONS: Increased HPV vaccination coverage in California is needed to reduce economic and health burdens associated with cancers caused by HPV infection.

A Vitamin Pattern Diet Is Associated with Decreased Risk of Gestational Diabetes Mellitus in Chinese Women: Results from a Case Control Study in Taiyuan, China.

Identification of modifiable dietary factors, which are involved in the development of gestational diabetes mellitus (GDM), could inform strategies to prevent GDM. Therefore, we examined the dietary nutrient patterns and evaluated their relationship with GDM risk in a Chinese population using a case control study design. A total of 1,464 GDM cases and 8,092 non-GDM controls were included in the final analysis. Dietary intake was assessed using a 33-item food frequency questionnaire, and nutrients were estimated using the Chinese Standard Tables of Food Consumption. Dietary nutrient patterns were identified using factor analysis, and their associations with GDM risk were evaluated using unconditional logistic regression models adjusting for total energy intake, maternal age, high blood pressure, education, maternal body mass index (BMI), parity, and family history of diabetes. A "vitamin" nutrient pattern was characterized as the consumption of diet rich in vitamin A, carotene, vitamin B2, vitamin B6, vitamin C, dietary fiber, folate, calcium, and potassium. For every quartile increase in the vitamin factor score during one year prior to conception, the first trimester, and the second trimester of pregnancy, the GDM risk decreased by 9% (OR: 0.91, 95%CI: 0.86-0.96), 9% (OR: 0.91, 95%CI: 0.86-0.96), and 10% (OR: 0.90, 95%CI: 0.85-0.95), respectively. The significant reduced GDM risk was seen in women regardless of age and parity, and slightly stronger effect was found in women whose age ≤ 30 and women who are nulliparous across the three time periods. The significant association was also found in women whose BMI ≤ 24 with similar effect size across the three time periods. Our study suggests that the vitamin nutrient pattern diet is associated with decreased GDM risk. Additional studies are necessary to explore the underlying mechanism of this relationship.

Single Nucleotide Polymorphisms in CDKAL1 Gene Are Associated with Risk of Gestational Diabetes Mellitus in Chinese Population.

Gestational diabetes mellitus (GDM) is a growing public health concern for many reasons, and its etiology remains unclear. Due to the similarity of its pathophysiology with type 2 diabetes (T2DM), we evaluated the relationship between published T2DM susceptibility genes and the risk of GDM. A total of 303 SNPs from genes including IRS1, IGF2BP2, CDKAL1, GCK, TCF7L2, KCNQ1, and KCNJ11 and the risk of GDM were examined in a nested case-control study with 321 GDM cases and 316 controls. The odds ratios (ORs) and their 95% confidence interval (95% CI) were estimated by unconditional logistical regression as a measure of the associations between genotypes and GDM in additive, recessive, dominant, and codominant models adjusting for maternal age, maternal BMI, parity, and family history of diabetes. At the gene level, CDKAL1 was associated with GDM risk. SNPs in the CDKAL1 gene including rs4712527, rs7748720, rs9350276, and rs6938256 were associated with reduced GDM risk. However, SNPs including rs9295478, rs6935599, and rs7747752 were associated with elevated GDM risk. After adjusting for multiple comparisons, rs9295478 and rs6935599 were still significant across the additive, recessive, and codominant models; rs7748720 and rs6938256 were significant in dominant and codominant models; and rs4712527 was only significant in the codominant model. Our study provides evidence for an association between the CDKAL1 gene and risk of GDM. However, its role in the GDM pathogenesis still needs to be verified by further studies.

43.3-year durability of a Smeloff-Cutter ball-caged mitral valve.

Extended durability of mechanical heart valves has been documented for many years. We describe a case of a ball-caged mechanical valve implanted 43.3 years previous to developing valve dysfunction. The patient presented with both prosthetic valve stenosis and insufficiency. This Smeloff-Cutter valve (Cutter Laboratories, Berkeley, CA) in the mitral position was dysfunctional due to lipid absorption, which resulted in ball variance and concomitant pannus growth prevented optimal seating of the ball in its cage. This is the longest length of time in which a Smeloff-Cutter mechanical valve has been originally implanted.
