A life where concealment and exposure coexist-The antiretroviral therapy adherence of people living with HIV infection: A phenomenological study.

AIM: The aim of this study is to identify the nature and structure of the real world experiences of people living with HIV infection and adhering to antiretroviral therapy (ART). DESIGN: Giorgi's phenomenological method was applied. METHODS: Data collection was conducted from 1 November 2016-1 September 2017. A total of six participants participated in the study. The Consolidated Criteria for Reporting Qualitative Research (COREQ) was used to report this study. RESULTS: The findings show that the structure of the experience of people living with HIV and adhering to ART is composed of six essential common constituents: (a) ART adherence has become a prerequisite for a normal life; (b) Endless adjustments responding to a sensitive body; (c) Dosing Time becomes the framework of the day; (d) Dosing time needing to coincide with the availability of confidential dosing space; (e) Classification of Relationships-those who know of my taking antiretroviral drugs and those who do not; and (f) Recognition of the multiple relationships affecting ART. CONCLUSION: Adhering to ART is experienced by people infected with HIV not only as a process they want to hide, but also a critical lifeline that stabilizes their lives. That is, their day-to-day living is split into a double life reflecting their coexisting need for concealment and exposure. IMPACT: Although much existing literature focuses on the adherence to medication, this study reveals the meaning of ART in the context of viewing the patient as an independent subject. Contrary with what people living with HIV want, they are at risk of external exposure during the process of treatment. This study highlights the need for nurses to communicate with patients about the strategies they need to meet the challenges they face.

Differences in Vancomycin Clearance between Trauma and Medical Intensive Care Unit Patients.

BACKGROUND: To identify the differences in the vancomycin pharmacokinetics between multiple trauma patients and medically ill patients in the intensive care unit (ICU) stratified by the use of continuous renal replacement therapy (CRRT), and the factors affecting vancomycin clearance (CLvan). MATERIALS AND METHODS: All the included patients received at least three consecutive doses of vancomycin, then, therapeutic drug monitoring was conducted. Patients' serum vancomycin trough levels and other clinical variables were identified retrospectively. The vancomycin pharmacokinetics and associated factors were compared and analyzed between trauma ICU (TICU) and medical ICU (MICU) patients. RESULTS: In the non-dialyzed group, the CLvan was higher among the TICU patients than the MICU patients. However, in the continuous renal replacement therapy group, there was no significant difference in the CLvan between the multiple trauma and medically ill patients. The only factor associated with CLvan in the non-dialyzed group was creatinine clearance; none of the factors was associated with CLvan in the CRRT group. CONCLUSION: In the case of non-dialyzed patients in the TICU, vancomycin dosages must be adjusted, depending on the patient's actual body weight changes. In the case of patients undergoing CRRT in both ICUs, vancomycin can be infused with fixed doses regardless of the patients' characteristics.

Cochlear Glucocorticoid Receptor and Serum Corticosterone Expression in a Rodent Model of Noise-induced Hearing Loss: Comparison of Timing of Dexamethasone Administration.

Glucocorticoid (GC) is a steroid hormone secreted from the adrenal cortex in response to stress, which acts by binding to cytoplasmic glucocorticoid receptors (GRs). Dexamethasone (DEX) is a synthetic GC exhibiting immunosuppressive effects in both human and rodent models of hearing loss. While clinical evidence has shown the effectiveness of DEX for treatment of various inner ear diseases, its mechanisms of action and the optimal timing of treatment are not well understood. In the present study, intergroup comparisons were conducted based on the time point of treatment with DEX: (1) pretreatment; (2) posttreatment; and (3) pre&post-noise. The pre&post DEX treatment group showed a significant improvement in threshold shift at 1 day post-noise exposure as compared to the TTS (transient threshold shift)-only group at 8 and 16 kHz. Both TTS and PTS (permanent threshold shift) significantly reduced cochlear GR mRNA expression and increased serum corticosterone and cochlear inflammatory cytokines. The pre&post DEX treatment group showed a significant decrease in serum corticosterone level as compared to other DEX treatment groups and TTS-treated group at 3 days after acoustic trauma. Our results suggest that the timing of DEX administration differentially modulates systemic steroid levels, GR expression and cochlear cytokine expression.

Micelle formulation of hexadecyloxypropyl-cidofovir (HDP-CDV) as an intravitreal long-lasting delivery system.

There still is an unmet need for a safe and sustained intravitreal drug delivery system. In this study we are proposing and characterizing a micelle based, clear-media intravitreal drug delivery system using the lipid derivatized nucleoside analog, hexadecyloxypropyl-cidofovir (HDP-CDV, CMX 001). HDP-CDV forms micelles in water and in vitreous supernatant with the critical micelle concentration of 19 µg/mL and 9 µg/mL, respectively at 37 °C. The formed micelles had the average size of 274.7 nm and the Zeta potential of -47.1 mV. Drug release study in the excised rabbit vitreous showed a sustained release profile with a half-life of 2.7 days. The micelle formulation of HDP-CDV demonstrated a good safety profile in two animal species (rabbit and guinea pig) following intravitreal injection. The sustained efficacy was tested in a pretreatment study design and the drug potency was tested in an ongoing herpes simplex virus (HSV-1) retinitis model. The pretreatment studies using single intravitreal injection and later HSV-1 infection revealed at least 9 weeks of vitreous presence and therapeutic level of HDP-CDV, with 71% eyes protection from infection. The treatment study demonstrated that intravitreal administration halted active HSV-1 retinitis in 80% of the infected eyes while cidofovir (CDV) treatment failed to suppress active HSV-1 retinitis. In summary, lipid derivatized nucleoside analogs can be formulated as a micelle intravitreal injection and provides a sustained drug release in vitreous for chronic retinal diseases.

Mild toxic anterior segment syndrome mimicking delayed onset toxic anterior segment syndrome after cataract surgery.

Toxic anterior segment syndrome (TASS) is an acute sterile postoperative anterior segment inflammation that may occur after anterior segment surgery. I report herein a case that developed mild TASS in one eye after bilateral uneventful cataract surgery, which was masked during early postoperative period under steroid eye drop and mimicking delayed onset TASS after switching to weaker steroid eye drop.

Relationship between Menstruation Distress and Coping Method among 3-shift Hospital Nurses.

PURPOSE: The purpose of this study was to identify menstrual distress, coping method and relief of symptoms among female nurses who worked with 3-shift. METHODS: A total of 185 participants were recruited from November 18, 2011 to January 30, 2012. The measurement included menstrual distress and coping method questionnaire and relief of symptoms. The data were analyzed using t-test, ANOVA, Pearson's correlation coefficients with SPSS 19.0. RESULTS: The level of menstrual distress was moderate (mean 3.0), and there were significant differences in menstrual distress by age, education, stress, regularity of menstrual cycle. Among the coping methods, coping according to menstrual cycle specific was the most frequently used, followed by active recognizing coping, active behavioral coping, and avoidance coping. Among the degree of symptom relief, symptom relief score was the highest when used coping according to menstrual cycle specific. Menstrual distress was associated with stress, adequate amount of sleep, dysmenorrhea and number of coping method total. CONCLUSION: Nurses experienced moderate levels of menstrual distress and used various types of coping to relieve it. There is a need for hospital nurses to develop an effective nursing intervention to relieve the menstrual distress and utilize active coping methods.

Investigation of hemodynamic changes in the ophthalmic artery using color Doppler imaging after strabismus surgery.

PURPOSE: We investigated hemodynamic changes in the ophthalmic artery (OA) using color Doppler imaging (CDI) after two horizontal rectus muscles surgery. METHODS: Eyes of the surgical group (n=18) underwent surgery on two horizontal rectus muscles, and the control group was the contralateral eyes. CDI of the OA was performed before operation and on postoperative days (POD) 1, 7 and 30. Peak systolic (Vmax), end diastolic (Vmin), and mean (Vmean) blood flow velocities were measured, and resistivity index (RI) and pulsatility index (PI) were calculated. RESULTS: Vmax, Vmin and Vmean were significantly higher, and RI and PI were significantly lower in the surgical group than in the control group on POD 1 (p<0.05). In the surgical group, Vmax, Vmin and Vmean were significantly higher, and RI and PI were significantly lower, on POD 1 than those measured on other days (p<0.05). CONCLUSIONS: We showed that surgery on the two horizontal rectus muscles increased OA blood flow during the early postoperative period.

A case refort of Sandhoff disease.

Sandhoff disease is a rare autosomal recessive metabolic disease presenting bilateral optic atrophy and a cherry red spot in the macula. This case report presents the characteristics of a patient with Sandhoff disease as assessed by ophthalmic, neuroimaging, and laboratory procedures. Ophthalmologic examination revealed that the patient could not fixate her eyes on objects nor follow moving targets. A pale optic disc and a cherry red spot in the macula were seen in both eyes. Low signal intensity at the thalamus and high signal intensity at the cerebral white matter were noted in a T2-weighted brain MR image. A lysosomal enzyme assay using fibroblasts showed the marked reduction of both total beta-hexosaminidases, A and B. Based on the above clinical manifestations and laboratory findings, we diagnosed the patient as having Sandhoff disease.

Detection of hepatitis B virus and Mycobacterium tuberculosis in Korean dental patients.

This study examined the detection rate of the hepatitis B virus (HBV) and Mycobacterium tuberculosis (Mtb) in serum and saliva samples, respectively, from 120 dental patients who were unaware if they have or had either hepatitis or tuberculosis. The frequencies of HBsAg and anti-HBs were determined using an immunochromatic assay. Mtb positivity was determined by the PCR method. Of the 120 patients, 7 (5.8%) were HBV positive and 30 (25.0%) were Mtb positive. This highlights the fact that dental health care workers (DHCWs) can be exposed to the risk of infection from blood- or saliva-borne pathogens as a consequence of their work. Therefore, it is very important to prevent cross infection between patients and dental personnel. Accordingly, laboratory tests prior to surgical treatment are needed to determine the infectious state of dental patients in order to prevent the transmission of infectious diseases in dental clinics.

Sensitive mother-to-adolescent disclosures after divorce: is the experience of sons different from that of daughters?

This study addressed two main questions: (a) Are adolescent sons and daughters exposed to sensitive maternal disclosures after divorce with similar frequency and in similar detail? and (b) Does gender act as a moderator in the association between maternal disclosures and adolescent adjustment difficulties? Forced-choice and open-ended data were collected from 194 adolescents within 2 years after their parents' divorce. Quantitative analyses revealed that although the majority of adolescents experience some level of maternal disclosure, neither frequency nor detail of maternal disclosure differed as a function of adolescent gender. Frequent and detailed maternal disclosures were associated with adolescent adjustment difficulties, primarily psychological distress. Gender did not moderate that significant association. Qualitative analysis shed light on the link between maternal disclosures and adolescent distress, suggested the importance of how disclosures are made, and revealed several gender differences in reactions to maternal disclosures. Implications of the findings are discussed.
