Objective: Chronic cough (CC) symptoms can persist as refractory or unexplained CC (RCC). We sought to characterize the clinical and economic burden of RCC.

Methods: In this retrospective US cohort study using data from Optum's de-identified CDM Database (01/2015-03/2022), CC was identified as ≥1 CC diagnosis or ≥3 cough events (with ≥8 weeks and ≤120 days between the first and third events and ≥3 weeks between any 2 events).

Chronic cough (CC), characterized as a cough lasting >8 weeks, is a common multi-factorial syndrome in the community, especially in older adults. Using a pre-existing algorithm to identify patients with CC within the 2011-2018 Medicare beneficiaries, we examined trends in gabapentinoid use through repeated cross-sectional analyses and identified distinct utilization trajectories using group-based trajectory modeling (GBTM) in a retrospective cohort study. Individuals without CC but with any respiratory conditions related to cough served as a comparator group.

The 2019 Infectious Diseases Society of America guideline for the management of community-acquired pneumonia (CAP) emphasizes the need for clinician to understand local epidemiological data to guide selection of appropriate treatment. Currently, the local distribution of causative pathogens and their associated resistance patterns in CAP is unknown. A retrospective observational study was performed of patients admitted to an 870-bed safety net hospital between March 2016 and March 2021 who received a diagnosis of CAP or healthcare-associated pneumonia within the first 48 hours of admission.

Article Synopsis
  • A study analyzed cough medication prescribing trends among chronic cough (CC) patients in Florida from 2012 to 2021 using a large clinical database, identifying distinct patterns in medication use.
  • Results showed increases in the use of benzonatate, dextromethorphan, and gabapentinoids among CC patients, while opioid antitussive use rose until 2015 and then declined significantly.
  • Among the 15,566 CC patients studied, most did not use cough medications, but those with chronic use faced significant health burdens and comorbidities compared to non-CC patients.

COVID-19 vaccines were developed at unparalleled speed, but racial disparities persist in vaccine uptake. This is a cross-sectional survey that was conducted in mid-2021 in ambulatory clinics across Brooklyn, New York. The objectives of the study were to assess: knowledge of COVID-19, healthcare communication and access, attitudes including trust in the process of vaccine development and mistrust due to racial discrimination, and to determine the relationship of the above to vaccine receipt.

Alzheimer's disease (AD) is the most common form of dementia, with the risk of developing it attributed to non-modifiable and modifiable factors. Currently, there is no cure for AD. A plant-based diet may protect against cognitive decline, due to the effects of plant-based nutrients such as vitamins, antioxidants, and fiber.

Using 2003−2018 National Ambulatory Medical Care Survey data for office-based visits and 2003−2018 National Hospital Ambulatory Medical Care Survey data for emergency department (ED) visits, we conducted cross-sectional analyses to examine cough medication (CM) use trends in the United States (US) ambulatory care settings. We included adult (≥18 years) patient visits with respiratory-infection-related or non-infection-related cough as reason-for-visit or diagnosis without malignant cancer or benign respiratory tumor diagnoses. Using multivariable logistic regressions, we examined opioid antitussive, benzonatate, dextromethorphan-containing antitussive, and gabapentinoid use trends.

Therapist Self-Disclosure (TSD), the revealing of a therapist's feelings, thoughts or personal information to a client, is an inevitable aspect of therapeutic relationships. However, despite its prevalence in clinical settings, we believe there is insufficient recognition and exploration of TSD in our work with children and adolescents. Because TSD is not often formally addressed during training, therapists across the spectrum of clinical child psychology and psychiatry are often left with the belief that disclosures are rare or inherently negative occurrences that should be avoided.

Objectives: Pregnant women are at increased risk of complications from influenza, and infants are at increased risk of pertussis. Maternal influenza and Tdap (tetanus, diphtheria, and acellular pertussis) vaccination can reduce risk of these infections and related complications. Our objective was to estimate vaccination coverage with influenza and Tdap vaccines during pregnancy among women with a recent live birth.

Psychogenic nonepileptic seizures (PNES) are challenging clinical occurrences consisting of any combination of altered movement, sensation, or awareness that resemble epileptic seizures (ES) but do not coincide with electrographic ictal discharges and are presumed to be neuropsychiatric-neurobehavioral in origin. Securing the PNES diagnosis is a crucial first step and is best confirmed by recording events on video-electroencephalogram (v-EEG) and finding an absence of ictal EEG changes and the presence of normal awake EEG rhythms before, during, and after the event. However, obstacles to timely diagnosis and referral to psychiatric treatment frequently occur, placing these patients at risk for harm from unnecessary medications and procedure as well as placing high burden on medical systems.

Vaccinating pregnant women with influenza and tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccines can reduce the risk for influenza and pertussis for themselves and their infants. The Advisory Committee on Immunization Practices (ACIP) recommends that all women who are or might be pregnant during the influenza season receive influenza vaccine, which can be administered any time during pregnancy (1). The ACIP also recommends that women receive Tdap during each pregnancy, preferably from 27 through 36 weeks' gestation (2).

Purposes: Despite recommendations against prostate cancer screening with prostate-specific antigen (PSA) tests, about one-fourth of men age ≥40 years received PSA tests in 2015. This study aimed to answer 3 questions for men who had a PSA test in the past year: (1) What percentage of these men received the test first suggested by physicians? (2) What factors were associated with physician-initiated PSA testing (PIPT) versus patient/someone else-initiated testing? (3) What percentage of patients ever had shared decision-making when tests were initiated by physicians?

Methods: We analyzed the 2000 and 2015 National Health Interview Survey data. We calculated age-standardized prevalence of PIPT for both years.
