Summary
Working with hands above shoulder level increases the risk of shoulder diseases. This systematic review quantifies the dose-response relationship, crucial for recognizing occupational shoulder conditions like rotator cuff lesions.
Area of Science:
- Occupational Health
- Epidemiology
- Musculoskeletal Disorders
Background:
- Epidemiological studies link shoulder-loaded work to shoulder diseases.
- Previous research lacked dose-response relationships for occupational disease recognition.
- This study updates a 2017 review with data up to November 2018.
Purpose of the Study:
- To derive the dose-response relationship for physical occupational demands and shoulder diseases.
- To estimate the doubling dose for occupational shoulder disease recognition.
- To update existing knowledge on occupational risk factors for shoulder conditions.
Main Methods:
- Systematic review and meta-analysis of epidemiological studies.
- Included exposures: hands at/above shoulder level, repetitive movements, forceful work, hand-arm vibrations.
- Defined shoulder diseases using ICD-10 codes M 75.1-5 (rotator cuff syndrome, etc.).
Main Results:
- Pooled analysis showed a 21% increased risk (95% CI 4-41%) per 1000 h of work with hands above shoulder level.
- No significant sex-specific differences in dose-response relationships were found.
- Meta-analysis was not feasible for other exposures due to limited studies and varied measurements.
Conclusions:
- This systematic review provides crucial dose-response data for recognizing occupational shoulder diseases, especially rotator cuff lesions.
- Quantifies the risk associated with prolonged work involving elevated arm postures.
- Highlights the need for further research on other occupational burdens due to data limitations.

01:23Muscles of the Shoulder
8.5K
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

01:03Dose-Response Relationship: Overview
4.6K
Agonists can bind with and activate receptors, resulting in the formation of drug-receptor complexes. Once formed, these complexes catalyze many biochemical processes at the cellular level and subsequently induce a pharmacologic response. The degree of response is directly proportional to the fraction of activated receptors, which in turn, depends on the concentration of the drug at the receptor site as well as the sensitivity of the receptor. An increase in the administered dose contributes to...

01:08Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment
196
Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...

AssessmentA comprehensive assessment is essential in managing a patient with rheumatic heart disease (RHD). Begin with obtaining a detailed medical history, including recent streptococcal infections, a history of rheumatic fever, or previously diagnosed rheumatic heart disease. Assess the patient for symptoms such as fever, chest pain, widespread joint pain (arthralgia), tachycardia, pericardial friction rub, muffled heart sounds, heart murmurs, peripheral edema, subcutaneous nodules, and...

01:15Drug Dosing: Geriatric Patients
174
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

01:22Dose-Response Relationship: Potency and Efficacy
6.2K
The potency of a drug is the measure of its ability to produce a biological response and can be compared by looking at the half-maximum effective concentration or EC50 values of different drugs. A lower EC50 value indicates higher potency of the drug. In the dose–response curve of two antihypertensive drugs, candesartan and irbesartan, a significant difference is observed in their EC50 values. A lower EC50 value for candesartan indicates that it is more potent than irbesartan, as it...
