Tarım ve Hayvancılıkta Değişen Dinamikler: İklim, Teknoloji ve Sürdürülebilirlik
No full textGlobal warming is reshaping the thermal, hydrological, and feed-quality constraints within which ruminant systems operate. Heat exposure depresses intake and productivity, compromises fertility, and increases health risks; meanwhile, drought and forage-quality variability add pressure on nutrient supply chains (Polsky & von Keyserlingk, 2017; West, 2003). For dairy systems, these pressures are already measurable and are projected to intensify over the coming decades. High-frequency datasets and classic syntheses converge on consistent declines in milk yield and composition during hot periods, with carryover effects beyond heat events (St-Pierre, Cobanov, & Schnitkey, 2003; Becker, Collier, & Stone, 2020). Within this context, nutrition plays a two-fold role. As adaptation, feeding strategies aim to sustain intake and rumen function under heat (e.g., ration energy density, DCAD/electrolytes, antioxidant support, water management); as mitigation, diet design lowers greenhouse-gas intensity per unit of product (e.g., improved forage quality, precision protein, lipid/tannin strategies) (Gerber et al., 2013; IPCC, 2021). These levers must be framed against robust nutrient requirements and tolerance data. Authoritative compendia including the modern NASEM dairy requirements and the NRC mineral tolerance monograph guide formulation and safety margins (NASEM, 2021; NRC, 2005). Recent evidence indicates that thresholds for adverse heat responses have shifted downward with higher-producing cows. While a THI of ~72 was historically cited as discomfort, contemporary work places critical responses near THI ≈ 68 for high-yield Holsteins, with observable changes in behavior and output at or below that value (Allen et. al., 2015; Becker et al., 2020). </p
Tension Pneumothorax Secondary to Hydatid Cyst Rupture
No full textA patient, diagnosed with two hydatid cysts in the right lung via thoracic computed tomography (CT) at a healthcare facility due to complaints of cough and dyspnea, was initiated on albendazole treatment. Two weeks after starting treatment, the patient presented to our Emergency Department with complaints of general malaise, severe respiratory distress, and chest pain. Following physical examination and radiodiagnostic evaluations, a diagnosis of tension pneumothorax was established, and urgent intrapleural air drainage was performed. After stabilization of the patient’s general condition, elective surgical treatment for the hydatid cyst was undertaken
