Identifying Foods That Optimize Intake of Key Micronutrients During Pregnancy.

BACKGROUND: Most pregnant women in the United States are at risk of inadequate intake of vitamin A, vitamin D, folic acid, calcium, iron, and omega-3 fatty acids from foods alone. Very few United States dietary supplements provide sufficient doses of all 6 nutrients without inducing excess intake. OBJECTIVE: We aimed to identify energy-efficient foods that provide sufficient doses of these nutrients and could be consumed in lieu of dietary supplements to achieve the recommended intake in pregnancy. METHODS: In a previous analysis of 2,450 pregnant women, we calculated the range of additional intake needed to shift 90% of participants to intake above the estimated average requirement and keep 90% below the tolerable upper level for these 6 nutrients. Here, we identified foods and beverages from the 2019 to 2020 Food and Nutrient Database for Dietary Studies that provide target levels of these nutrients without exceeding the additional energy intake recommended for pregnancy beginning in the second trimester (340 kilocalories). RESULTS: We identified 2358 candidate foods meeting the target intake range for at least one nutrient. No candidate foods provided target amounts of all 6 nutrients. Seaweed (raw or cooked without fat) provided sufficient vitamin A, folate, calcium, iron, and omega-3s (5 of 6 nutrients) but would require an intake of >5 cups/d. Twenty-one other foods/beverages (mainly fish, vegetables, and beverages) provided target amounts of 4 of the 6 nutrients. Few foods met targets for vitamin D (n = 54) or iron (n = 93). CONCLUSIONS: Results highlight the difficulty in meeting nutritional requirements from diet alone and imply that dietary supplements are likely necessary to meet vitamin D and iron targets in pregnancy, as well as omega-3 fatty acid targets for individuals who do not consume fish products. Other foods could be added in limited amounts to help meet intake targets without exceeding caloric recommendations or nutrient safety limits.

Selecting a dietary supplement with appropriate dosing for 6 key nutrients in pregnancy.

BACKGROUND: Most pregnant women in the United States (US) are at risk of inadequate intake of key nutrients during pregnancy from foods alone. Current dietary supplement practices reduce risk of inadequacy for only some nutrients and induce excessive intake of other nutrients. OBJECTIVES: Our study aimed to estimate the doses of supplementation needed to help most pregnant women achieve the recommended intake without exceeding upper limits for key prenatal nutrients and to identify US dietary supplements providing these doses. METHODS: We conducted 24-h dietary recalls in 2450 pregnant participants aged 14-50 y from 2007 to 2019. We estimated the usual intake of vitamins A and D, folate, calcium, iron, and ω-3 FAs from foods alone. We calculated the target doses of supplementation needed to shift 90% of participants to consume above the estimated average requirement and keep 90% below the tolerable upper limit. We identified products in the Dietary Supplement Label Database providing these target doses of supplementation. RESULTS: The target dose for supplementation was ≥198 mcg retinol activity equivalents of total vitamin A (with ≤2063 mcg preformed retinol); 7-91 mcg vitamin D; 169-720 mcg dietary folate equivalents of folic acid; 383-943 mg calcium; 13-22 mg iron; and ≥59 mg ω-3 FAs. Out of 20,547 dietary supplements (including 421 prenatal products), 69 products (33 prenatal) contained all 6 nutrients; 7 products (2 prenatal) contained target doses for 5 nutrients. Only 1 product (not a prenatal) contained target doses for all 6 nutrients, but it currently costs ∼USD200/mo and requires 7 tablets per daily serving. CONCLUSIONS: Almost no US dietary supplements provide key nutrients in the doses needed for pregnant women. Affordable and convenient products that fill the gap between food-based intake and estimated requirements of pregnancy without inducing excess intake are needed to support pregnant women and their offspring.

Early unprotected return to contact sport after metacarpal fixation in professional athletes.

AIMS: To determine whether an early return to sport in professional Australian Rules Football players after fixation of a non-thumb metacarpal fracture was safe and effective. PATIENTS AND METHODS: A total of 16 patients with a mean age of 25 years (19 to 30) identified as having a non-thumb metacarpal fracture underwent open reduction and internal plate and screw fixation. We compared the players' professional performance statistics before and after the injury to determine whether there was any deterioration in their post-operative performance. RESULTS: Of the 16, 12 sustained their fracture during the season: their mean time to return to unrestricted professional play was two weeks (1 to 5). All except two of the 48 player performance variables showed no reduction in performance post-operatively. CONCLUSION: Our data suggest that professional athletes who sustained a non-thumb metacarpal fracture can safely return to professional play without restriction two weeks after internal fixation.

The influence of cartilage thickness at the sigmoid notch on inclination at the distal radioulnar joint.

AIMS: The aims of this study were: firstly, to investigate the influence of the thickness of cartilage at the sigmoid notch on the inclination of the distal radioulnar joint (DRUJ), and secondly, to compare the sensitivity and specificity of MRI with plain radiographs for the assessment of the inclination of the articular surface of the DRUJ in the coronal plane. PATIENTS AND METHODS: Contemporaneous MRI images and radiographs of 100 wrists from 98 asymptomatic patients (mean age 43 years, (16 to 67); 52 male, 53%) with no history of a fracture involving the wrist or surgery to the wrist, were reviewed. The thickness of the cartilage at the sigmoid notch, inclination of the DRUJ and Tolat Type of each DRUJ were determined. RESULTS: The assessment using MRI scans and cortical bone correlated well with radiographs, with a kappa value of 0.83. The mean difference between the inclination using the cortex and cartilage on MRI scans was 12°, leading to a change of Tolat type of inclination in 66% of wrists. No reverse oblique (Type 3) inclinations were found when using the cartilage to assess inclination. CONCLUSION: These data revealed that when measuring the inclination of the DRUJ using cartilage, reverse oblique inclinations might not exist. The data suggest that performing an ulna shortening osteotomy might be reasonable even in distal radioulnar joints where the plain radiographic appearance suggests an unfavourable reverse oblique inclination in the coronal plane. We recommend using MRI to validate radiographs in those that appear to be reverse oblique (Tolat Type 3), as the true inclination might be different, thereby removing one possible contraindication to ulnar shortening.

Examining the impact of patient characteristics and symptomatology on knowledge, attitudes, and beliefs among foreign-born tuberculosis cases in the US and Canada.

Foreign-born individuals represent the majority of TB cases in the US/Canada. Little is known about their TB knowledge, attitudes, and beliefs (KAB). Cross-sectional survey was conducted in 22 sites in the US/Canada among foreign-born adults with active TB. Multiple regression was used to examine KAB factors against covariates. Of 1,475 participants interviewed, most answered the six knowledge items correctly. Significant predictors of correct knowledge included region of origin, education, income, age, visa status, place of diagnosis, BCG vaccination, and TB symptoms. Significant predictors of higher perceived risk/stigma scores included region of origin, age, place of diagnosis, English fluency, time in the US/Canada, TB symptoms, and household rooms. This study examines associations between TB KAB and patient and disease characteristics in foreign-born individuals in the US/Canada. The findings call for improved health education, along with efforts to reduce stigma and enhance realistic risk assessments.

Are tobacco control policies effective in reducing young adult smoking?

PURPOSE: We examined the influence of tobacco control program funding, smoke-free air laws, and cigarette prices on young adult smoking outcomes. METHODS: We use a natural experimental design approach that uses the variation in tobacco control policies across states and over time to understand their influence on tobacco outcomes. We combine individual outcome data with annual state-level policy data to conduct multivariable logistic regression models, controlling for an extensive set of sociodemographic factors. The participants are 18- to 25-year-olds from the 2002-2009 National Surveys on Drug Use and Health. The three main outcomes are past-year smoking initiation, and current and established smoking. A current smoker was one who had smoked on at least 1 day in the past 30 days. An established smoker was one who had smoked 1 or more cigarettes in the past 30 days and smoked at least 100 cigarettes in his or her lifetime. RESULTS: Higher levels of tobacco control program funding and greater smoke-free-air law coverage were both associated with declines in current and established smoking (p < .01). Greater coverage of smoke-free air laws was associated with lower past year initiation with marginal significance (p = .058). Higher cigarette prices were not associated with smoking outcomes. Had smoke-free-air law coverage and cumulative tobacco control funding remained at 2002 levels, current and established smoking would have been 5%-7% higher in 2009. CONCLUSIONS: Smoke-free air laws and state tobacco control programs are effective strategies for curbing young adult smoking.

A comprehensive examination of the influence of state tobacco control programs and policies on youth smoking.

OBJECTIVES: We examined the influence of tobacco control policies (tobacco control program expenditures, smoke-free air laws, youth access law compliance, and cigarette prices) on youth smoking outcomes (smoking susceptibility, past-year initiation, current smoking, and established smoking). METHODS: We combined data from the 2002 to 2008 National Surveys on Drug Use and Health with state and municipality population data from the US Census Bureau to assess the associations between state tobacco control policy variables and youth smoking outcomes, focusing on youths aged 12 to 17 years. We also examined the influence of policy variables on youth access when these variables were held at 2002 levels. RESULTS: Per capita funding for state tobacco control programs was negatively associated with all 4 smoking outcomes. Smoke-free air laws were negatively associated with all outcomes except past-year initiation, and cigarette prices were associated only with current smoking. We found no association between these outcomes and retailer compliance with youth access laws. CONCLUSIONS: Smoke-free air laws and state tobacco control programs are effective strategies for curbing youth smoking.

Early experience with the TriMed fragment-specific fracture fixation system in intraarticular distal radius fractures.

This paper reports the results of fixation of intraarticular fractures of the distal radius using the TriMed fragment-specific fixation system by surgeons early in their experience with the system. A consecutive series of 22 AO types C2 and C3 fractures in 21 patients were internally fixed with the system. Restoration of articular congruity to less than 2 mm was possible in 20 fractures. At a minimum of 6 months follow-up, mean volar and radial inclination were 8 degrees and 25 degrees , respectively, with no loss of reduction. The patients had a mean of 50 degrees flexion, 63 degrees extension and a pronation-supination arc of 149 degrees . The mean subjective Patient Rated Wrist Score was 20. Our complication rate was comparable to other published series despite long operating times. Therefore, we commend the system as a powerful tool to treat these difficult fractures but acknowledge the significant learning curve.

Surgery for cerebral palsy part 3: classification and operative procedures for thumb deformity.

Spastic thumb deformity is the result of imbalance between intrinsic and extrinsic forces acting across unstable joints. This paper presents a classification of spastic thumb deformity based on the accurate assessment of the deforming forces, outlines methods for their correction and reviews the results of our surgery. Thumb reconstruction procedures were performed in 32 patients with 33 spastic thumb deformities. All patients were assessed pre- and postoperatively using the same functional assessment system which was performed by the same team. The thumb was maintained out of the palm in 29 patients and lateral pinch was established in 26 patients.

Treating injuries in active seniors.

A physician who treats many masters athletes in his practice suggests an approach to managing active seniors' injuries that avoids ageism: Don't treat them any differently than younger patients. Overuse injuries are the most common sports injuries among older patients. The emphasis of rehabilitation and injury prevention strategies is on improving strength and flexibility. Preparticipation exam strategies that evaluate age-related declines and chronic medical conditions help physicians keep patients safe during activity. Arthritis obstacles can be overcome with medication, stretching, strength training, and physician encouragement.

Veterinary high pressure injection injuries with inoculations for larger animals.

Equipment used in the mass vaccination of farm stock is a source of high pressure injection injury. We present four cases due to chicken vaccine, and one due to pig vaccine. Unlike injuries caused by paint or oil guns the vaccination delivers a fixed volume. Although the vaccine is in a mineral oil carrier it appears to elicit little inflammatory reaction in a small dose. The outcome is related to the volume injected. In chicken vaccine the dose is small enough to allow conservative or minimally invasive management. The large volume in pig vaccine requires treatment as for conventional high pressure injection injuries.

Painful Knees: When Damaged Menisci Are the Cause.

Damage to the meniscus can lead to knee pain in active people of all ages, from the adolescent basketball player to the senior tennis player. Joint-line tenderness, catching or locking, and other clues revealed during the history and physical exam will help the clinician accurately diagnose meniscus injuries-even without MRI.

How to Detect Lyme Disease.

If patients lack the characteristic sign of Lyme disease-a red rash with a pale center-diagnosing the disease can be challenging. A thorough workup and history should alert physicians when patients' flulike symptoms are the result of this tick-borne infection.
