Hatchability And Nestling Viability In An Extremely Short-Beaked Pigeon Breed, Türker Savaş, Hakan Erdem, Cemi̇l Tölü

Turkish Journal of Veterinary & Animal Sciences

The selection of hobby animals for breeding by enthusiasts is often based on aesthetic considerations, which can have a negative impact on the animals’ biology. Furthermore, “extreme traits” that deviate from ancestral norms, such as short beaks in pigeons, can be detrimental to the animal’s welfare. Beaks perform many essential functions, such as facilitating feed intake and eggshell breaking. The present study investigates possible hatching problems and the nestling viability of short-beak pigeons through a study of the breeding records of Mısıri (short beak), Baska (medium beak), and Turkish Dönek (normal beak) pigeons, as well as data from one breeding …

Attentional Blindness Of The Clinical Gaze, Lily Anderson-Chavarria

Clinical Research in Practice: The Journal of Team Hippocrates

This article presents the case of Mr. C, a patient who received over 65 imaging tests without any pathology ever being found. The case is well-explained by a social science concept known as the clinical gaze, a socio-cognitive process of assigning pathological explanations to diseased bodies. This article provides some historical context for the concept and applies it to the case of Mr. C. When viewed through a social science lens, the excess imaging underwent by Mr. C transforms from something seemingly irrational to an almost inevitable outcome of the modern medical diagnostic process.

When Systems Fail: The Impact Of Protocol On Physician Moral Distress, Aya Dudar

Clinical Research in Practice: The Journal of Team Hippocrates

Physicians often face the decision between following rigid hospital protocol and doing the right thing for the patient, creating moral distress and contributing to burnout. This letter describes a case in which an elderly patient with COVID-19 pneumonia and a DNI order developed worsening hypercapnia and required noninvasive ventilation. Despite clinical appropriateness, hospital policy prohibited BiPAP use in obtunded patients due to aspiration risk - even when the resident offered continuous bedside monitoring. This case highlights the ethical tension that arises when rigid hospital policies prevent physicians from making real-time exceptions in appropriate situations. Empowering physicians to make context-driven decisions …

A Comparative Analysis Of Maladaptive Perfectionism In Male And Female Competitive Bodybuilders, Maddox B. Utter, Christian O. Quintero, Samantha S. Dardaman, Stephen E. Rowden, Scott B. Martin

International Journal of Exercise Science: Conference Proceedings

Bodybuilding is a sport focused on physique optimization, where success is determined by judges’ evaluations of muscle mass, symmetry, and definition. Due to the sport’s emphasis of physical aesthetics, bodybuilders may feel the need to compare themselves with other competitors. This evaluation and comparison of physique may expose athletes to maladaptive perfectionistic tendencies, such as setting unattainably high standards, excessive worry over mistakes, and a diminished sense of competence. While current bodybuilding literature is limited, previous research suggests that perfectionism may lead to psychological impairments (e.g., body dysmorphia, anxiety, and reduced self-confidence) which may manifest differently between male and female …
