Risk factors for lactation mastitis in China: A systematic review and meta-analysis.

PLoS One 2021 13;16(5):e0251182. Epub 2021 May 13.

Third Affiliated Hospital of Beijing University of Chinese Medicine, Beijing, China.

Background: Lactation mastitis (LM) affects approximately 3% to 33% of postpartum women and the risk factors of LM have been extensively studied. However, some results in the literature reports are still not conclusive due to the complexity of LM etiology and variation in the populations. To provide nationally representative evidence of the well-accepted risk factors for LM in China, this study was aimed to systematically summary the risk factors for LM among Chinese women and to determine the effect size of individual risk factor.

Partial range of motion training elicits favorable improvements in muscular adaptations when carried out at long muscle lengths.

Eur J Sport Sci 2021 May 12:1-24. Epub 2021 May 12.

Weight Training Laboratory, School of Physical Education, Physiotherapy and Occupational Therapy, Federal University of Minas Gerais, Belo Horizonte, Minas Gerais, Brazil.

The study compared changes in strength and regional muscle hypertrophy between different ranges of motion (ROM) in the knee extension exercise. Forty-five untrained women were randomized to either a control group or to perform the exercise in one of the following 4 groups (0°=extended knee): Full ROM (FULL: 100°-30° of knee flexion); Initial Partial ROM (INITIAL: 100°-65°); Final Partial ROM (FINAL: 65°-30°); Varied ROM (VAR: daily alternation between the ROM of INITIAL and FINAL). Pre- and post-training assessments included one repetition maximum (1RM) testing in the ROM corresponding to the initial, final and full ROM, and measurement of cross-sectional areas of the rectus femoris and vastus lateralis muscles at 40%, 50%, 60% and 70% of femur length in regard to regional muscle hypertrophy.

Higher Hand Grip Strength Is Associated With Greater Radius Bone Size and Strength in Older Men and Women: The Framingham Osteoporosis Study.

JBMR Plus 2021 May 30;5(5):e10485. Epub 2021 Mar 30.

Hinda and Arthur Marcus Institute for Aging Research, Hebrew SeniorLife Boston Massachusetts USA.

Mechanical loading by muscles elicits anabolic responses from bone, thus age-related declines in muscle strength may contribute to bone fragility in older adults. We used high-resolution peripheral quantitative computed tomography (HR-pQCT) to determine the association between grip strength and distal radius bone density, size, morphology, and microarchitecture, as well as bone strength estimated by micro-finite element analysis (μFEA), among older men and women. Participants included 508 men and 651 women participating in the Framingham Offspring Study with grip strength measured in 2011-2014 and HR-pQCT scanning in 2012-2015. Read More

Leg press and chest press strength normative values by half-decades in older persons.

Exp Gerontol 2021 May 8:111401. Epub 2021 May 8.

University of Miami, Laboratory of Neuromuscular Research and Active Aging, Department of Kinesiology and Sports Sciences, Coral Gables, FL, USA; University of Miami, Miller School of Medicine, Center on Aging, Miami, FL, USA. Electronic address:

Evaluating muscular strength is vital to the application of effective training protocols that target quality of life and independence in older individuals. Resistance training is a valuable tool to improve functional capacity, strength, and power in this population; however, the lack of normative values for common lifts such as the leg press (LP) and chest press (CP) reduce its utility. This study developed age- and sex-specific normative strength values for older individuals. Read More

Res Nurs Health 2021 May 7. Epub 2021 May 7.

Department of Physiotherapy, Faculty of Health Sciences, University of Granada, Granada, Spain.

A current challenge in breast cancer (BC) patients is how to reduce the side effects of cancer and cancer treatments and prevent a decrease in quality of life (QoL). Neurotoxic side effects, especially from chemotherapy, are present in up to 75% of women with BC, which implies a large impact on QoL. There is a special interest in the preventive possibilities of therapeutic exercise (TE) for these neurological sequelae, and the benefits of TE could be improved when it is combined with vagal activation techniques (VATs).

Impaired bone microarchitecture and strength in patients with tumor-induced osteomalacia.

J Bone Miner Res 2021 May 5. Epub 2021 May 5.

IDIM, Universidad del Salvador, Buenos Aires, Argentina.

Some studies based on bone biopsy have demonstrated that in patients with tumor-induced osteomalacia (TIO) the mineralization process of the bone matrix is profoundly disturbed. However, the interrelationship between clinical and biochemical features and bone microarchitecture in this disease needs further analysis. With this purpose in mind, we set out three objectives: i) to determine bone microarchitecture and estimated bone strength in a group of patients with tumor-induced osteomalacia using high-resolution peripheral quantitative computed tomography (HR-pQCT) and finite element analysis (FEA), ii) to investigate correlations between duration of disease, biochemical features, bone density, HR-pQCT and FEA parameters, and iii) to compare HR-pQCT and FEA parameters with a healthy control group.
