概括
温度变化对巴西与高温相关的住院住院情况产生了重大影响. 较低的温度变化增加了热浪期间住院的风险,突出了严重的公共卫生问题.
科学领域:
- 环境健康 环境健康
- 流行病学 流行病学
- 气候科学 气候科学
背景情况:
- 关于温度变化 (TV) 如何影响热量健康关联的证据有限,特别是在巴西等发展中国家.
- 了解这种相互作用对于极端高温事件期间的公共卫生策略至关重要.
研究的目的:
- 调查巴西的温度变化 (TV) 对环境热量和住院病人的关联的修改.
- 评估不同水平的电视如何影响与热有关的疾病和伤害的风险.
主要方法:
- 利用来自巴西1,814个城市 (2000-2015年热季) 的每日住院和天气数据.
- 采用准松回归与受约束的滞后模型来估计低和高电视日的热-住院关联.
- 采用随机效应元分析,并根据地区,性别,年龄和病因进行分层分析.
主要成果:
- 在全国范围内,每天平均气温上升5°C,在电视频率低的日子里,住院的风险增加了4.4%,而在电视频率高的日子里则增加了2.7%.
- 电视显著改变了东北,东南和南部地区以及大多数年龄和性别群体 (不包括0-4岁的儿童和80岁以上的老年人) 的热病住院关联.

As a nurse, it is vital to understand the factors affecting body temperature to monitor variations and effectively evaluate deviations from regular.
Factors may include:

Decreased Body Temperature
573
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

Increased Body Temperature
611
A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Methods of reducing fever
611
The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.
Step 3: Assess the patient's...

Factors Affecting Illness
4.0K
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...
