We aimed to identify methamphetamine use patterns and impact by gender/sexual orientation among people with HIV (PWH) in care. We queried 3-month drug use/impact. Women were grouped by gender (cis/trans); cisgender men by sexual orientation. Differences in drug use/impact were assessed using chi-squared and t-tests. We used linear and logistic regression models for each drug use measure, adjusting for age and race/ethnicity. Among 13938 PWH (MA 48), 30% reported ever using methamphetamine; 10% reported current use; 79% were cisgender men (74% men who have sex with men (MSM), 20% men who have sex with women (MSW), 6% men who have sex with men/women (MSMW). Among women (21%), 8% were transgender (TW). TW and MSM reported higher current methamphetamine use (each 14%) than other groups [MSMW (13%), MSW (6%), CW (3%)(p < 0.001)]. Severity of use was highest among TW, compared to MSM (17.8 vs. 14.1, p = 0.04). All groups using methamphetamine were more likely than MSM to currently use cocaine/crack (p = 0.002-0.04); all but TW were more likely than MSM to report illicit opioid use (p < 0.001-0.03). MSM had highest injection use (34% vs. 17-25%, p = 0.05). Related health/legal/financial/social problems were most frequent among TW and MSMW (71%, 55%)]. Persons currently using methamphetamine had lower antiretroviral adherence than those not using (81-85% vs. 91-94%), and higher detectable viral load (28-41% vs. 13-20%). In the adjusted analysis, TW were more likely than MSM to report daily/almost daily use (p = 0.04). Methamphetamine use and impact differ by gender and by cisgender men's sexual orientation, warranting inquiry into moderating factors.

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Therapeutic Drug Monitoring: Affecting Factors01:29

Therapeutic Drug Monitoring: Affecting Factors

Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Bias in Epidemiological Studies

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Impact of Groups on Individuals01:28

Impact of Groups on Individuals

Groups play a fundamental role in shaping individual behavior, as they establish norms that guide interactions and decision-making. Social psychology examines how individuals conform to group expectations, often adjusting their attitudes and actions to align with group norms. These norms can be formal, such as workplace policies, or informal, such as unspoken social expectations within a fraternity.Conformity and Social InfluenceConformity arises when individuals modify their behaviors or...

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...
