Co-delivery of streptomycin and hydroxychloroquine by labeled solid lipid nanoparticles to treat brucellosis: an animal study

Can brucellosis-related biochemical and immunological parameters be used as diagnostic and treatment indicators? The goal of this project was to look at biochemical parameters, trace elements, and inflammatory factors in the acute and chronic stages of brucellosis after treatment with streptomycin and hydroxychloroquine-loaded solid lipid nanoparticles (STR-HCQ-SLN). The double emulsion method was used for the synthesis of nanoparticles. Serum levels of trace elements, vitamin D, CRP, and biochemical parameters were measured in rats involved in brucellosis. The therapeutic effect of STR-HCQ-SLN was compared with that of free drugs. In both healthy and infected rats, serum concentrations of copper, zinc, iron, magnesium, potassium, and biochemical parameters of the liver were significantly different. By altering the serum levels of the aforementioned factors, treatment with STR-HCQ-SLN had a positive therapeutic effect on chronic brucellosis. Vitamin D levels declined (46.4%) and CRP levels rose (from 7.5 mg to less than 1 mg) throughout the acute and chronic stages of brucellosis. This study showed that by comparing the biochemical parameters and the levels of trace elements in the serum of healthy and diseased mice in the acute and chronic stages of brucellosis, it is possible to get help from other routine methods for diagnosis.

Cutaneous Manifestations of Anabolic-Androgenic Steroid Use in Bodybuilders and the Dermatologist's Role in Patient Care

Young adults have been increasingly facing pressure to achieve an appealing athletic physique, often influenced by social media influencers on platforms like Instagram. This viewpoint highlights the association between image-centric social media, dissatisfied body image, the use of anabolic-androgenic steroids (AAS) to achieve desired results, and the overlooked dermatological side effects of AAS, including acne and acne fulminans. We underscore the importance of recognizing acne fulminans as an indicator of possible AAS abuse and encourage dermatologists to actively identify and address AAS use to improve their patients' well-being.

Anabolic Androgenic Steroid Abuse and their Health Impacts: A Cross-sectional Study among Body Builders in a City of Eastern India

Background:

Anabolic-androgenic steroids (AASs), when taken in supraphysiologic doses, increase muscle strength and athletic performance. Evidence suggests that long-term use of AAS in supraphysiologic doses have adverse effects on health. Therefore, the study was conducted to find crude estimate of the prevalence of AAS use among attendees of the gymnasium, the factors that could have influenced them for AAS abuse and to assess the short- and long-term side effects as perceived by them.

Methods:

A cross-sectional study was conducted in selected gymnasiums of a smart city of India using a predesigned and pretested questionnaire. Snowball sampling method was undertaken. The study was from July 2015 to June 2016. Informed written consent was taken. The analysis was done using SPSS v. 20.0.

Results:

Of 84 bodybuilders approached, 74 participants used AAS. All users were male with mean age of 26.5 + 0.55 years. The mean age of initiation of AAS abuse was 23 years, and 66.2% (49) were unmarried. Eighty-five percent (63) preferred injectable. Seventy percent (52) abusers were influenced by trainers for abuse. Most commonly abused was Nandrolone decanoate (55.4%). Seventy-three percent were not aware of any legal ban on steroids. Reported benefits include increased strength, muscle size, and power, while harms were increased acne, deepening of voice, swelling of feet, increased irritability, depressive thoughts, impaired judgment, panic disorder, and withdrawal effect.

Conclusions:

Frequency of ASS use was substantial among young bodybuilders. Awareness about side effects was not a deterrent factor. Abusers were highly influenced by coaches. Efforts should be made for preventing easy access to AAS.

Anabolic Androgenic Steroids: Searching New Molecular Biomarkers

Even if anabolic androgenic steroid (AAS) abuse is clearly associated with a wide spectrum of collateral effects, adolescents and athletes frequently use a large group of synthetic derivatives of testosterone, both for aesthetic uses and for improving performance. Over the last few years, the development of MicroRNA (miRNA) technologies has become an essential part of research projects and their role as potential molecular biomarkers is being investigated by the scientific community. The circulating miRNAs detection as a diagnostic or prognostic tool for the diagnosis and treatment of several diseases is very useful, because with a minimal quantity of sample (peripheral blood), miRNAs are very sensitive. Even more, miRNAs remain stable both at room temperature and during freeze-thaw cycles. These characteristics highlight the important role of miRNAs in the near future as new tools for anti-doping. The article provides a systematic review and meta-analysis on the role of miRNAs as new potential molecular biomarkers of AAS use/abuse. Particularly, this paper analyzed the “miRNA signature” use as biomarkers for health disorders, focusing on the organ damages which are related to ASS use/abuse. Moreover, this review aims to provide a future prospect for less invasive or non-invasive procedures for the detection of circulating miRNA biomarkers as doping assumption signaling.

Phenotypic and genotypic characterization of macrolide, lincosamide and streptogramin B resistance among clinical isolates of staphylococci in southwest of Iran

Objective

The present study aimed to determine the phenotypic and genotypic profile of macrolide, lincosamide and streptogramin B (MLS_B) resistance in clinical isolates of staphylococci.

Results

This cross-sectional study was conducted on 164 non-duplicated staphylococci isolates collected during August 2015 to February 2016 from two tertiary care hospitals in Shiraz, southwest of Iran. Of the 164 isolates, 86 erythromycin-resistant isolates consist of 35 Staphylococcus aureus and 51 coagulase negative staphylococci (CoNS) were included in the study. Of the 35 S. aureus, the prevalence of cMLS (constitutive), iMLS (inducible), and MS phenotypes were found 82.9%, 8.6% and 8.6%, respectively. Among 51 CoNS, the frequencies of cMLS, iMLS, and MS phenotypes were detected 66.7%, 11.8% and 21.6%, respectively. Among S. aureus isolates, the predominant genes were ermC in 82.9% isolates, followed by ermA in 57.1% and msrA in 28.6% of isolates. Among CoNS isolates, the most frequent genes were diagnosed ermC in 70.6% isolates followed by msrA in 68.6% and ermA in 11.8% of isolates. In conclusion, regarding the presence of MLS_B resistance in our region, diagnosis of this resistance type on a routine basis in staphylococcal clinical isolates is of particular importance.

The Occurrence of Nosocomial Pathogens on Cell Phones of Healthcare Workers in an Iranian Tertiary Care Hospital

BACKGROUND

Cell phones have become one of the necessary means of life and they are commonly used almost everywhere by every population. Colonized microorganisms on cell phones can be easily cross-transmitted. Given the widespread prevalence of nosocomial infections, this study aimed to determine the frequency of bacterial contamination and antibiotic resistance in cell phones of healthcare workers (HCWs) in a tertiary care hospital, from southwest of Iran. In this cross-sectional study conducted between April and June 2016, sampling were performed from cell phones of 25 nurses and 75 medical students.

METHODS

Samples were collected from each cell phone by a moistened cotton swap dipped in normal saline prior and after decontamination with available alcohol-based handrubs. Identification of bacterial isolates was performed by conventional microbiologic methods. Antibiotic susceptibility pattern of the isolates was determined using the disk diffusion method. The contamination rates of cell phones prior and after disinfection were 88% and 52%, respectively. Ninety-nine (71.2%) out of 139 isolated distinct bacterial colonies prior to cleaning were potentially nosocomial pathogens. Of them, staphylococci (88.9%) were the most prevalent bacteria, in which 40.9% were methicillin-resistant isolates. The majority of Gram-positive and - negative isolates were susceptible to the tested antimicrobials. Totally, contamination rate of cell phones was significantly reduced after decontamination. Regular disinfection of the hands and cell phones was significantly associated with reduction of colonization of the methicillin-resistant isolates.

RESULT & CONCLUSION

These findings emphasize the restricted use of cell phones and encourage the higher compliance with hygienic practices in hospitals to reduce the risk of nosocomial infections.

Adverse health effects of androgen use

Anabolic androgenic steroids (AAS) are performance enhancing drugs commonly used by athletes and bodybuilders to improve appearance and athletic capability. Unfortunately, these testosterone derivatives can be associated with serious and potentially irreversible side effects, and can impact multiple organ systems. It is important that physicians be familiar with these adverse consequences so that they can appropriately counsel patients whom they suspect of AAS-abuse. In this chapter, we will review the negative effects of these compounds on various organ systems in men using AAS.
