Human nutrition, and what can be considered “ideal” nutrition, is a complex, multi-faceted topic which many researchers and practitioners deliberate. While some attest that basic human nutrition is relatively understood, it is undeniable that a global nutritional problem persists. Many countries struggle with malnutrition or caloric deficits, while others encounter difficulties with caloric overconsumption and micronutrient deficiencies. A multitude of factors contribute to this global problem. Limitations to the current scope of the recommended daily allowances (RDAs) and dietary reference intakes (DRIs), changes in soil quality, and reductions in nutrient density are just a few of these factors. In this article, we propose a new, working approach towards human nutrition designated “Foundational Nutrition”. This nutritional lens combines a whole food approach in conjunction with micronutrients and other nutrients critical for optimal human health with special consideration given to the human gut microbiome and overall gut health. Together, this a synergistic approach which addresses vital components in nutrition that enhances the bioavailability of nutrients and to potentiate a bioactive effect.

The purpose of this investigation was to compare changes in circulating lymphocyte subset cell counts between high-intensity interval exercise (HIIE), sprint interval exercise (SIE), and moderate-intensity continuous exercise (MICE). Recreationally active men (n = 11; age: 23 ± 4 yr; height: 179.9 ± 4.5 cm; body mass: 79.8 ± 8.7 kg; body fat %:12.6 ± 3.8%; V̇O2max: 46.6 ± 3.9 ml⋅kg−1⋅min−1) completed a maximal graded exercise test to determine maximal oxygen uptake (V̇O2max) and three duration-matched cycling trials (HIIE, SIE, and MICE) in a randomized, counterbalanced fashion. HIIE consisted of fifteen 90-s bouts at 85% V̇O2max interspersed with 90-s active recovery periods. SIE consisted of fifteen 20-s bouts at 130% maximal power and 160-s active recovery periods. MICE was a continuous bout at 65% V̇O2max. Total exercise duration was 53 min in all three trials, including warm-up and cool-down. Blood was collected before, immediately post, 30 min, 2 h, 6 h, and 24 h post-exercise. Changes in lymphocyte subset counts, and surface expression of various markers were analyzed via flow cytometry. Changes were assessed using mixed model regression analysis with an autoregressive first order repeated measures correction. Significant decreases were observed in absolute counts of CD56dim NK cells, CD19+ B cells, CD4+ T cells, and CD8+ T cells 30 min and 24-h post-exercise in all three trials. Despite resulting in greater total work and oxygen consumption, MICE elicited similar changes in lymphocyte subset counts and receptor expression compared to both SIE and HIIE. Similarly, while the two interval trials resulted in differing oxygen consumption and total work, no differences in the lymphocyte response were observed. Though both forms of exercise resulted in declines in circulating lymphocyte cell counts, neither exercise type provides an immune-related advantage when matched for duration.

Radical cystectomy with pelvic lymphadenectomy is the method of choice for muscle-invasive urothelial cell cancer (UCC) treatment and provides the best cancer-specific survival. It can be performed as an open radical cystectomy (ORC), laparoscopic radical cystectomy (LRC) or robot-assisted surgery (RARC). The aim of this study was to compare laparoscopic and open radical cystectomy in terms of perioperative and oncological results. This retrospective study included 260 patients who underwent surgery due to invasive bladder cancer. A laparoscopic radical cystectomy (LRC) was performed on 131 patients and an open radical cystectomy (ORC) on 129 patients. Group was stratified according to the urinary diversion. Oncologic results expressed as perioperative variables were analyzed, adjusted to the type of urinary diversion. The LRC patients were in worse perioperative condition according to the American Society of Anesthesiologists (ASA) score than the ORC group (3.1 and 2.52, respectively; p = 0.001). The serum protein level was significantly lower in the ORC group, with no difference in body mass index (BMI) between the groups. The median operation time was significantly shorter in the LRC group with ileal conduit and uretero-cutaneostomy than in the same groups operated using open approach (252.5 min and 180 min vs 290 min and 225 min, respectively), as was the hospital discharge time (8.18 days and 11.63 days, respectively; p = 0.004). In both LRC groups, median blood loss was lower, compared with corresponding ORC groups (325 mL and 400 ml vs 800 mL and 1,100 mL, respectively; p < 0.001 in both cases). The level of complications was significantly lower in both LRC groups than in the ORC groups (p < 0.001 and p = 0.001, respectively). The lymph node yield was 12 in the LRC group and 10 in the ORC group. The LRC group had a lower positive surgical margins ratio. The laparoscopic approach should be a valid option for radical cystectomy, given the fewer complications, smaller blood loss, and shorter operating and hospitalization times experienced by patients who underwent a laparoscopic cystectomy.
• Aerobic exercise in the heat promotes modest increases in plasma TNF-α and STNFR1. • Increases in TNF-α and STNFR1 are likely driven by changes in core temperature. • TNFR1 and 2 expression on non-classical monocytes is blunted one hour post-exercise. • TNFR1 expression on non-classical monocytes is elevated during exercise in the heat.
