Background: Well defined constitutional parameters support the physical fatigue resistance in handball to maintain the performance level for the majority of actions. Ideal constitutional conditions are necessary to achieve these physiological advantages in handball. But limited knowledge exists about the upper body posture or the postural control in correlation to the Body Mass Index (BMI), playing years, playing position and throwing arm in professional male handball.
Methods: Ninety-one male handball players participate (24.1 ± 5.9 years; playing experience 16.6 ± 5.7 years). A three-dimensional back scanner and a pressure measuring plate were used.
Results: Correlations between BMI and upper body posture and postural control were not significant. Same counts for the comparison between the left and right throwing arm according to upper body posture and postural control ( ≥ 0.05). Correlations between the years of playing can be found at pelvis height ( ≤ 0.04) and for the length of the Center of Pressure (CoP) ( ≤ 0.01). Wing players are 6.5-8.5 cm smaller. The playing position is independently of BMI, age or upper body posture ( ≥ 0.05). Backcourt players have a higher load of the left and a lower load of the right foot compared to wing players ( ≤ 0.001). Left-right comparison ( ≤ 0.001/ 0.01) can be seen in pivot player (covered area), backcourt player (weight distribution left/right [rear] foot), wing player (weight and force distribution left/right foot, covered area).
Conclusion: Goalkeeper, Backcourt and pivot players are taller and heavier than wing players. These physiological demands are not detectable in the upper body posture and slightly in postural control. Wing players have the most asymmetric load distribution and the longest length of CoP. Since goalkeepers do not differ from pivot or backcourt players, this can be lead back to the same training.

Biting midges of genus Leptoconops Skuse 1889 are small blood-feeding insects recognized as highly irritating diurnal pests in certain regions around the globe. In Europe, their presence is poorly documented, except in France and Italy. Following reports of human discomfort in a tourist area of Menorca, Balearic Islands (Spain), a small-scale study was conducted to identify the biting species and assess their preferred biting sites using a human-landing assay along a habitat gradient in a coastal dune area.

Animal thermoregulation may have significant costs and compete directly or indirectly with other energetically demanding processes, such as immune function. Although the subterranean environment is characterized by thermally-stable conditions, small changes in ambient temperature could be critical in shaping immunity. However, little is known about the effects of ambient temperature, in naturally varying ranges, on immunity of wild species.

Background: Malnutrition is linked to more postoperative problems, a longer recovery period, and a higher death rate; preoperative nutritional condition is a critical factor in surgical outcomes.
Objective: This study aimed to evaluate the impact of preoperative nutritional status on surgical outcomes in general surgery patients and explore its broader public health implications.
Methodology: A two-year observational research with 440 adult patients undergoing general surgery was carried out between January 2022 and December 2023.

It's interesting to note that despite clinical improvements in upper airway dimensions, the maxillary, mandibular, and mandibular body lengths remained smaller than those of controls. This finding may represent an underlying neurocristopathy, which represents a deficiency in the population of neural crest cells available in the embryonic maxillary and mandibular processes de novo. Indeed, it is known that craniofacial dimensions in infants with malformations, such as cleft palate, are often smaller when compared to non-cleft counterparts.

In this work, we present and evaluate a closed-loop, continuous myoelectric prosthetic hand controller, that can continuously control the position of multiple degrees of freedom of a prosthesis while rendering proprioceptive feedback to the user via a haptic feedback armband. Twenty-eight participants without and ten participants with upper limb difference (ULD) were recruited to holistically evaluate the physical and psychological effects of the controller via isolated control and sensory tasks, dexterity assessments, embodiment and task load questionnaires, and post-study interviews.
