Empresas podem começar 2027 sem recolher a CBS
A cobrança da CBS pode não começar em 1º de janeiro de 2027. Embora essa seja a data prevista pela EC 132/23 para a nova tributação e extinção do PIS e da Cofins, há um passo prévio: a fixação, pelo Senado Federal, da alíquota de referência do tributo, com base em cálculos do TCU. O calendário oficial está definido. A Receita Federal enviou ao TCU, em 14 de setembro de 2026, a proposta de metodologia de cálculo, ainda sem número definido.
Distrato na moradia de interesse social

Com 170 mil unidades investigadas por possível uso indevido em São Paulo, a conta não pode ficar com quem comprou sem informação.
Effectiveness of Whole-Body Vibration Therapy on Handgrip Strength: A Systematic Review and Meta-Analysis of Randomized Controlled Trials
1 Introduction Handgrip strength has been widely used as a key metric for assessing overall physical fitness and functional capacity, reflecting the integrity of the neuromuscular system and the ability to generate force during daily or high-performance activities. It has emerged as an important biomarker of health (Vaishya et al. 2024).
Systematic review and meta-analysis of the effects of exercise in older adults with sarcopenia
Abstract Aging is associated with progressive physiological changes that impair physical functioning and quality of life (QoL), as exemplified by sarcopenia, a condition characterized by the loss of skeletal muscle mass and strength that increases the risk of falls, dependency, and mortality. Although physical exercise is widely recognized as an effective intervention, the literature remains heterogeneous with respect to the most appropriate modalities for this population.
Countermovement jump peak force discriminates low hip bone mineral density in postmenopausal women
Abstract Postmenopausal women are at increased risk of low bone mineral density (BMD) and osteoporotic fractures, yet access to dual-energy X-ray absorptiometry (DXA) remains limited in many settings. This study evaluated the diagnostic accuracy of countermovement jump (CMJ)-derived variables for identifying low BMD in postmenopausal women.
