Muscles that Move the Arm

Muscles that Move the Arm

Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

Components of Language

Components of Language

Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs.

Components of Stress

Components of Stress

Stress analysis under multiple loading conditions is intricate, necessitating a comprehensive grasp of normal and shearing stresses. Consider a small cube at point O, subjected to stress on all six faces, visible or not. Normal stress components σx, σy, σz act perpendicularly to the x, y, and z axes. Shearing stress components τxy and τxz are exerted on faces perpendicular to these axes.
Interestingly, the hidden cube faces also experience these stresses, equal and...

Intermolecular Forces

Intermolecular Forces

Atoms and molecules interact through bonds (or forces): intramolecular and intermolecular. The forces are electrostatic as they arise from interactions (attractive or repulsive) between charged species (permanent, partial, or temporary charges) and exist with varying strengths between ions, polar, nonpolar, and neutral molecules. The different types of intermolecular forces are ion–dipole, dipole–dipole, hydrogen bonds, and dispersion; among these, dipole–dipole, hydrogen...

Electromotive Force

Electromotive Force

Electricity is generated by either electrons or ions flowing through a solution or a conducting medium. This flow of electrons or specifically electrical charge is defined as an electric current. When electrons move through a wire, they generate an electric current. It can be recalled that in a redox reaction, electrons are lost and gained. In the spontaneous redox reaction of zinc with copper, when zinc is immersed in a copper ion solution, a transfer of electrons from one substance to...

Intermolecular vs Intramolecular Forces

Intermolecular vs Intramolecular Forces

Intermolecular forces (IMF) are electrostatic attractions arising from charge-charge interactions between molecules. The strength of the intermolecular force is influenced by the distance of separation between molecules. The forces significantly affect the interactions in solids and liquids, where the molecules are close together. In gases, IMFs become important only under high-pressure conditions (due to the proximity of gas molecules). Intermolecular forces dictate the physical properties of...

Summary

Coccidioidomycosis, a fungal infection, affected U.S. service members from 2007-2017, with incidence decreasing over time. Healthcare providers should consider this infection in febrile respiratory illnesses, especially after travel to endemic areas.

Background:

Coccidioidomycosis, a fungal infection caused by *Coccidioides* species, is endemic to the southwestern United States.
Active component U.S. service members may be at risk due to occupational and environmental exposures.

Purpose of the Study:

To describe the incidence and trends of coccidioidomycosis among active component U.S. service members from 2007 to 2017.
To identify demographic and occupational risk factors associated with coccidioidomycosis in this population.

Main Methods:

Retrospective analysis of incident coccidioidomycosis cases among active component service members from 2007-2017.
Calculation of unadjusted incidence rates per 100,000 person-years (p-yrs).
Comparison of rates across demographic, occupational, and geographic subgroups.

Main Results:

574 incident cases of coccidioidomycosis were reported, with an overall incidence rate of 3.9 cases per 100,000 p-yrs.
Higher rates observed in individuals aged 40+, Navy members, enlisted personnel, and healthcare occupations.
Incidence rates decreased from 5.2 in 2007 to 2.3 per 100,000 p-yrs in 2017.
Most U.S. cases (85.0%) were linked to southwestern endemic areas, primarily California and Arizona.

Conclusions:

Coccidioidomycosis incidence in U.S. service members declined between 2007 and 2017.
Specific demographic and occupational groups exhibited higher risk.
Healthcare providers should maintain a high index of suspicion for coccidioidomycosis in febrile respiratory illnesses, especially with travel history to endemic regions.
