Effects of a Collaborative Intervention Process on Parent-Therapist Interaction: A Randomized Controlled Trial.

Aim: To determine whether a collaborative intervention process facilitates parent-therapist interactions. Methods: Participants were 18 children with physical disabilities, their mothers, and 16 physical therapists. Therapists randomized to the experimental group were instructed in strategies for collaboration (working together) with parents in goal setting, planning, and implementing interventions. Family-therapist dyads participated in 6 weekly sessions. Four sessions were videotaped and combined (1st and 2nd for goal-setting/planning, 3rd and 5th for implementation) to code behaviors using Response Class Matrix. Multivariate analysis of variance was used to compare therapist and parent behaviors between groups. Results: Therapists in the experimental group demonstrated a higher frequency of "seeking information" (p < 0.01), "giving information" (p < 0.05), "positive behavior" (p < 0.01) and lower frequency of "child-related behavior" (p < 0.001) than therapists in the comparison group during goal-setting/planning and implementation. Parents in the experimental group demonstrated a higher frequency of "giving information" than parents in the comparison group (p < 0.01) during goal-setting/planning and implementation. Conclusion: Parents and therapists in the experimental group interacted more with each other, whereas those in the comparison group focused more on the child. The collaborative strategies appear to have increased parent participation in the intervention process, which has been a challenge for physical and occupational therapists.

Effects of a Collaborative Intervention Process on Parent Empowerment and Child Performance: A Randomized Controlled Trial.

AIMS: To examine the effects of a four-step collaborative intervention process on parent and child outcomes and describe parents' and therapists' experiences. METHODS: Eighteen children with physical disabilities, their mothers, and 16 physical therapists participated. Therapists randomized to the experimental group were instructed in the collaborative intervention process. All family-therapist dyads participated in six weekly sessions. Outcomes included the adapted Family Empowerment Scale (FES) and Canadian Occupational Performance Measure (COPM). A questionnaire was completed by parents and therapists to rate and describe their experiences. RESULTS: Mean scores on the FES (p <.05) and COPM (p <.001) increased after intervention but there were no group differences (p >.05). Effect size for change in child performance (.73) and parent satisfaction (1.08) on the COPM favored the experimental group. Parents in the experimental group were more confident in carrying out activities during daily routines (p =.01) and worked together with therapists to a greater extent (p =.01) than parents in the comparison group. Therapists in the experimental group perceived that they provided information/instruction (p <.01) and worked together with parents (p =.02) to a greater extent than therapists in the comparison group. CONCLUSIONS: Findings support the importance of shared goal setting for children's activities. Further research is recommended.

The effects of Self-Book© art therapy on cancer-related distress in female cancer patients during active treatment: A randomized controlled trial.

OBJECTIVE: National attention on patients' cancer-related emotional distress produced a need for evidence-based, psychosocial interventions in oncology care. The purpose of this study was to evaluate the efficacy of Self-Book© art therapy for emotional distress and psychological well-being of female oncology patients during active oncology treatment. METHODS: Sixty consenting women with cancer were randomly assigned to either a 6-session Self-Book© art therapy program or standard care. A repeated measures randomized controlled trial design was employed. Data were collected by using the Distress Thermometer, Perceived Emotional Distress Inventory, Patient-Reported Outcomes Measurement Information System Brief Psychological Well-being test, and the Functional Assessment of Chronic Illness Therapy Spiritual Well-being. Measurements were obtained at baseline, week 3, week 6, and 1 to 2 months post intervention. RESULTS: Forty participants were included in the final analysis. No significant differences between groups were found for the primary outcome measures: emotional distress and psychological well-being. Greater improvements in Self-Book© art therapy participants' spiritual well-being were found compared with the standard care control participants (P = .02). CONCLUSIONS: Although no statistically significant differences were present between the groups for the primary outcomes, several positive trends were noted. Thirty percent of Self-Book© art therapy participants reported postintervention emotional distress scores that were below the abnormal range for emotional distress, compared with only 5% of standard care control participants, suggesting that Self-Book© art therapy may have clinical value. Further studies are recommended to better understand the therapeutic mechanisms of Self-Book© art therapy for enhancing psychological well-being.

A comparison of complication rates in early-stage breast cancer patients treated with brachytherapy versus whole-breast irradiation.

BACKGROUND: The adoption of breast brachytherapy into clinical practice for early-stage breast cancer has increased over the last several years. Studies evaluating complication rates following treatment with brachytherapy have shown conflicting results. We compared local toxicity in patients treated with brachytherapy with those treated with whole-breast irradiation (WBI). METHODS: We identified 417 early-stage breast cancer patients treated with breast-conserving surgery and radiation between 2004 and 2010, and compared 271 women treated with intracavitary brachytherapy with 146 women treated with WBI. Long-term complications were assessed using Kaplan-Meier curves with the log-rank test. RESULTS: Median follow-up was 4.6 years, and the 5-year incidence of infectious skin complications (9.7 vs. 11.0 %, p = 0.84), abscess (1.1 vs. 0 %, p = 0.15), telangiectasia (8.0 vs. 5.3 %, p = 0.35), and breast pain (14.2 vs. 9.4 %, p = 0.2) was similar between the brachytherapy and WBI cohorts. The brachytherapy cohort had a higher 5-year rate of seroma (46.5 vs. 18.5 %, p < 0.001), and fat necrosis (39.5 vs. 24.4 %, p < 0.001). Brachytherapy patients trended towards more frequent biopsies as a result of fat necrosis to rule out a recurrence (11.2 vs. 6.7 %, p = 0.13). CONCLUSIONS: Patients treated with intracavitary brachytherapy had more local toxicity, particularly seroma and fat necrosis. Patients should be counseled on the possible increased rate of long-term complications associated with brachytherapy treatment.

Differences of Mortality Rates between Pocket and Nonpocket Cardiovascular Implantable Electronic Device Infections.

BACKGROUND: A steady rise in the use of cardiovascular implantable electronic devices (CIEDs), particularly in the elderly, has led to an increase in device-related infections. Although often studied and reported as a single entity, these complications in fact comprise a heterogeneous group. Specific subgroups may be associated with distinct mortality risks. METHODS: Medical records of all patients who underwent device extraction for CIED-related infection at a single tertiary referral center between 1991 and 2007 were reviewed. Infections were divided into four subgroups: primary pocket site infection (PPSI), pocket site infection with bacteremia, primary/isolated bacteremia (PIB), and device-related infective endocarditis (DRIE). Clinical presentation, laboratory data, and mortality rates were obtained by chart review and by querying the Social Security Death Index. RESULTS: A total of 387 cases were analyzed. The overall in-hospital and 1-year all-cause mortality rates were 7.2% and 25.3%, respectively. Patients with PIB or DRIE had significantly higher mortality rates (hazard ratio [HR] 2.3; 95% confidence interval [CI] 1.2-4.6 and HR 2.5; 95% CI 1.6-4.1, respectively) when compared with patients in the PPSI group. Patients who did not receive a new device during the initial admission also had a higher 1-year mortality rate compared to those who did (HR 2.7; 95% CI 1.8-4.1). CONCLUSIONS: Our patients with CIED-related infections requiring extraction/hospitalization had a significant mortality risk. Presence of pocket site infection carried a more favorable prognosis, regardless of the presence of bacteremia. Early detection and prevention of CIED-related infections with PIB (i.e., no pocket site involvement), especially for high-risk populations, is needed.

The impact of music therapy versus music medicine on psychological outcomes and pain in cancer patients: a mixed methods study.

PURPOSE: The purpose of this study was to compare the impact of music therapy (MT) versus music medicine (MM) interventions on psychological outcomes and pain in cancer patients and to enhance understanding of patients' experiences of these two types of music interventions. METHODS: This study employed a mixed methods intervention design in which qualitative data were embedded within a randomized cross-over trial. Thirty-one adult cancer patients participated in two sessions that involved interactive music making with a music therapist (MT) and two sessions in which they listened to pre-recorded music without the presence of a therapist (MM). Before and after each session, participants reported on their mood, anxiety, relaxation, and pain by means of visual analogue and numeric rating scales. Thirty participants completed an exit interview. RESULTS: The quantitative data suggest that both interventions were equally effective in enhancing target outcomes. However, 77.4 % of participants expressed a preference for MT sessions. The qualitative data indicate that music improves symptom management, embodies hope for survival, and helps connect to a pre-illness self, but may also access memories of loss and trauma. MT sessions helped participants tap into inner resources such as playfulness and creativity. Interactive music making also allowed for emotional expression. Some participants preferred the familiarity and predictability of listening to pre-recorded music. CONCLUSIONS: The findings of this study advocate for the use of music in cancer care. Treatment benefits may depend on patient characteristics such as outlook on life and readiness to explore emotions related to the cancer experience.

Effect of preoperative MRI on mastectomy and contralateral prophylactic mastectomy rates at a community hospital by a single surgeon.

Magnetic resonance imaging (MRI) use in the preoperative evaluation of newly diagnosed breast cancer (BC) patients is rising. We evaluated MRI as a function of surgical year with respect to mastectomy and contralateral prophylactic mastectomy (CPM) rates by a single surgeon. From January 2000 to December 2010, 1,279 patients with 1,296 breast cancers were identified. Our breast MRI was installed in April 2006. Mastectomy and CPM rates were evaluated by surgical year and stratified as "pre-MRI" or "MRI" depending on whether surgery occurred before or after April 2006. There was a significant increase in the percentage of patients undergoing MRI in the "pre-MRI" versus "MRI" era (17.2% versus 78.7%, p < 0.001). In contrast, mastectomy rates decreased with 29.9% undergoing mastectomy before 2006 versus 24.5% after 2006 (p = 0.038). Except for 2007, where CPM rates dropped to 7.1%, CPM rates increased from 16.7% in 2000 to 51.9% in 2010 (p = 0.033). The use of MRI, additional MRI findings and additional MRI biopsies were not associated with the decision for CPM. Age <50 was the only factor associated with CPM (RR = 2.12, p = 0.001). In our community hospital, mastectomy rates have decreased despite the increased use of preoperative MRI. MRI alone may not explain the increasing rates of mastectomy reported in other series. CPM rates have dramatically increased over time, seemingly independent of MRI use. Prospective studies are needed to assess the role of surgeon bias, along with other factors, in surgical decision making.

Infrared imaging does not predict the presence of malignancy in patients with suspicious radiologic breast abnormalities.

The NoTouch BreastScan (NTBS) is a non-invasive infrared imaging device which measures thermal gradients in breasts using dual infrared cameras and computer analysis. We evaluated NTBS as a predictor of breast cancer in patients undergoing minimally invasive biopsy. In this IRB-approved prospective trial, 121 female patients underwent NTBS prior to scheduled tissue biopsy. Twenty-two patients were excluded due to uninterpretable scans (n = 18), diagnosis of a nonprimary breast malignancy (n = 1), or no biopsy performed (n = 3) for a total of 99 patients. Five patients had bilateral breast biopsies and one patient had two ipsilateral biopsies, resulting in 105 biopsies. Patients were prospectively scanned using a high specificity mode, termed NTBS1. All 99 patients were retrospectively re-evaluated in a high sensitivity mode, NTBS2. Of 105 biopsies performed in 99 women, 33 (31.4%) were malignant and 72 (68.6%) were benign. NTBS1 demonstrated a sensitivity of 45.5% and a specificity of 88.9%. Of 94 normal contralateral breasts, 9.6% had a positive NTBS1. In the retrospective evaluation, NTBS2 demonstrated a sensitivity of 78.8% and a specificity of 48.6%. Half (50%) of the normal contralateral breasts had a positive NTBS2. NTBS does not accurately predict malignancy in women with suspicious imaging abnormalities. The higher sensitivity mode results in an unacceptable number of false positives, precluding its use. Infrared imaging did not improve the sensitivity or specificity of mammography in this clinical setting.

Effective Doses of Low-Dose Naltrexone for Chronic Pain - An Observational Study.

Purpose: Despite the availability of a wide variety of analgesics, many patients with chronic pain often experience suboptimal pain relief in part related to the absence of any medication to address the nociplastic component of common pain syndromes. Low-dose naltrexone has been used for the treatment of chronic pain, typically at 4.5 mg per day, even though it is also noted that effective doses of naltrexone for chronic pain presentations range from 0.1 to 4.5 mg per day. We performed an observational analysis to determine the range of effective naltrexone daily dosing in 41 patients with chronic musculoskeletal pain. Methods: Charts of 385 patients, 115 males, 270 females, ages 18-92, were reviewed. Two hundred and sixty patients with chronic diffuse, symmetrical pain were prescribed a titrating dose of naltrexone to determine a maximally effective dose established by self-report of 1) reduction of diffuse/generalized and/or severity level of pain and/or 2) positive effects on mood, energy, and mental clarity. Brief Pain Inventory and PROMIS scales were given pre- and post-determining a maximally effective naltrexone dose. Results: Forty-one patients met all criteria for inclusion, successfully attained a maximally effective dose, and completed a pre- and post-outcome questionnaire. Hormesis was demonstrated during the determination of the maximally effective dosing, which varied over a wide range, with statistically significant improvement in BPI. Conclusion: The maximally effective dose of low-dose naltrexone for the treatment of chronic pain is idiosyncratic, suggesting the need for 1) dosage titration to establish a maximally effective dose and 2) the possibility of re-introduction of low-dose naltrexone to patients who had failed initial trials on a fixed dose of naltrexone.

Low-dose naltrexone (LDN) has been used to treat chronic pain. There is, however, no agreed on effective dose, leaving clinicians without guidelines on initiating treatment with naltrexone. It appears that the dose of LDN for any patient is idiosyncratic, and in a small study, ranges from 0.1 to 6.0 mg/day. Understanding the various possible mechanisms of action of LDN may help the clinician to understand how and why it can effectively reduce chronic pain. A titration schedule to establish the maximally effective dose for chronic myofascial pain is presented.

Association of multiple metabolic and cardiovascular markers with the risk of cognitive decline and mortality in adults with Alzheimer's disease and AD-related dementia or cognitive decline: a prospective cohort study.

Background and objectives: There is a scarcity of data stemming from large-scale epidemiological longitudinal studies focusing on potentially preventable and controllable risk factors for Alzheimer's disease (AD) and AD-related dementia (ADRD). This study aimed to examine the effect of multiple metabolic factors and cardiovascular disorders on the risk of cognitive decline and AD/ADRD. Methods: We analyzed a cohort of 6,440 participants aged 45-84 years at baseline. Multiple metabolic and cardiovascular disorder factors included the five components of the metabolic syndrome [waist circumference, high blood pressure (HBP), elevated glucose and triglyceride (TG) concentrations, and reduced high-density lipoprotein cholesterol (HDL-C) concentrations], C-reactive protein (CRP), fibrinogen, interleukin-6 (IL-6), factor VIII, D-dimer, and homocysteine concentrations, carotid intimal-medial thickness (CIMT), and urine albumin-to-creatinine ratio (ACR). Cognitive decline was defined using the Cognitive Abilities Screening Instrument (CASI) score, and AD/ADRD cases were classified using clinical diagnoses. Results: Over an average follow-up period of 13 years, HBP and elevated glucose, CRP, homocysteine, IL-6, and ACR concentrations were significantly associated with the risk of mortality in the individuals with incident AD/ADRD or cognitive decline. Elevated D-dimer and homocysteine concentrations, as well as elevated ACR were significantly associated with incident AD/ADRD. Elevated homocysteine and ACR were significantly associated with cognitive decline. A dose-response association was observed, indicating that an increased number of exposures to multiple risk factors corresponded to a higher risk of mortality in individuals with cognitive decline or with AD/ADRD. Conclusion: Findings from our study reaffirm the significance of preventable and controllable factors, including HBP, hyperglycemia, elevated CRP, D-dimer, and homocysteine concentrations, as well as, ACR, as potential risk factors for cognitive decline and AD/ADRD.

Inhibition of NF-κB activity by HIV-1 Vpr is dependent on Vpr binding protein.

Numerous studies have reported that Vpr alters NF-κB signaling in various cell types, however, the findings have been largely conflicting with reports of both stimulatory and inhibitory effects of Vpr. Our aim was to investigate the role of Vpr signaling in myeloid cells using an adenovirus based expression and indicator system. Our results show that Vpr is inhibitory to NF-κB, however, this effect is dependent on the particular manner of NF-κB stimulation. Consistent with this notion, we report that Vpr has inhibitory effects that are specific to the TNF-α pathway, but not affecting the LPS pathway, suggesting that differential targets of Vpr may exist for NF-κB regulation. Further, we identify VprBP as one possible cellular component of Vpr's regulation of IκBα in response to TNF-α stimulation. We did not identify such a role for HSP27, which instead seems to inhibit Vpr functions. Chronically HIV-1 infected U1 cells with knockdown constructs for Vpr were unexpectedly less responsive to TNF-α mediated viral replication, perhaps suggesting that other HIV-1 components may antagonize these anti-NF-κB effects in infected cells. We hypothesize that Vpr may serve an important role in the context of viral infection and immune function in vivo, through its selective inhibition of NF-κB pathways.

Serum folate but not vitamin B-12 concentrations are positively associated with cognitive test scores in children aged 6-16 years.

Folate and vitamin B-12 are important for nervous system functioning at all ages, with important roles in functions such as neurotransmitter synthesis. Although studies suggest a relation between folate and vitamin B-12 and cognitive function in the elderly population, there is relatively less evidence regarding these vitamins and children's cognitive function. The purpose of the study was to examine the associations of serum folate and vitamin B-12 with cognitive performance in children 6-16 y old in the NHANES III, conducted from 1988 to 1994, prior to the implementation of folic acid fortification. A cross-sectional analysis was conducted using data on 5365 children 6-16 y old from NHANES III. Serum folate and vitamin B-12 concentrations were measured, along with performance, on the Wide Range Achievement Test-Revised and the Wechsler Intelligence Scale for Children-Revised. Associations of B vitamins with cognitive performance were assessed using linear regression models adjusted for various covariates. Higher serum concentrations of folate were associated with higher reading and block design scores after adjusting for various covariates. For example, compared with the lowest quartile of folate, children in the highest quartile scored 3.28 points or 0.19 SD units higher on the reading test (P < 0.05). Vitamin B-12 was not associated with any of the test scores. In the largest study to date, higher folate concentrations were associated with better reading and block design scores. These associations appear to be biologically plausible and merit further study.

Metabolic syndrome biomarkers predict lung function impairment: a nested case-control study.

RATIONALE: Cross-sectional studies demonstrate an association between metabolic syndrome and impaired lung function. OBJECTIVES: To define if metabolic syndrome biomarkers are risk factors for loss of lung function after irritant exposure. METHODS: A nested case-control study of Fire Department of New York personnel with normal pre-September 11th FEV(1) and who presented for subspecialty pulmonary evaluation before March 10, 2008. We correlated metabolic syndrome biomarkers obtained within 6 months of World Trade Center dust exposure with subsequent FEV(1). FEV(1) at subspecialty pulmonary evaluation within 6.5 years defined disease status; cases had FEV(1) less than lower limit of normal, whereas control subjects had FEV(1) greater than or equal to lower limit of normal. MEASUREMENTS AND MAIN RESULTS: Clinical data and serum sampled at the first monitoring examination within 6 months of September 11, 2001, assessed body mass index, heart rate, serum glucose, triglycerides and high-density lipoprotein (HDL), leptin, pancreatic polypeptide, and amylin. Cases and control subjects had significant differences in HDL less than 40 mg/dl with triglycerides greater than or equal to 150 mg/dl, heart rate greater than or equal to 66 bpm, and leptin greater than or equal to 10,300 pg/ml. Each increased the odds of abnormal FEV(1) at pulmonary evaluation by more than twofold, whereas amylin greater than or equal to 116 pg/ml decreased the odds by 84%, in a multibiomarker model adjusting for age, race, body mass index, and World Trade Center arrival time. This model had a sensitivity of 41%, a specificity of 86%, and a receiver operating characteristic area under the curve of 0.77. CONCLUSIONS: Abnormal triglycerides and HDL and elevated heart rate and leptin are independent risk factors of greater susceptibility to lung function impairment after September 11, 2001, whereas elevated amylin is protective. Metabolic biomarkers are predictors of lung disease, and may be useful for assessing risk of impaired lung function in response to particulate inhalation.

Philadelphia's Lead Court is making a difference.

The Philadelphia Lead Court (PLC) was created as an innovative law enforcement strategy to compel property owners to comply with city health codes to remediate their properties of lead hazards, which had led to elevated blood lead levels and lead poisoning in resident children. This study presents a detailed account of and analyzes the opinions of fifteen key informants drawn from the Philadelphia health and law departments and judicial system that staff and run the PLC in response to a fifteen-question structured survey. Main themes reviewed include the effectiveness of the PLC as compared with precourt law enforcement strategies and within the context of a specialized court, the use of fines, the impact of grant funding for remediation work, the major advantages and disadvantages of the PLC, and suggested changes to improve court function, followed by key recommendations. The article concludes that our informants found that the PLC has been very effective and successful. This model could be replicated by other cities with similar health code enforcement challenges.

A single-institution review of accelerated partial breast irradiation in patients considered "cautionary" by the American Society for Radiation Oncology.

BACKGROUND: The American Society for Radiation Oncology (ASTRO) issued a consensus statement in 2009 regarding patient selection for accelerated partial breast irradiation (APBI) following breast-conserving surgery (BCS) for breast cancer (BC). We reviewed our single-institution experience with APBI in patients considered "cautionary" by ASTRO to determine patterns of recurrence. METHODS: An institutional review board-approved, retrospective chart review was conducted from January 2004 to November 2009. We identified 106 "cautionary" patients with 109 BC. All patients were treated with BCS followed by APBI via balloon catheter brachytherapy. "Cautionary" criteria include patients aged 50-59 years, tumor size 2.1-3.0 cm, close margins (<2 mm), focal lymphovascular invasion, estrogen receptor (ER)-negative tumors, invasive lobular carcinoma, or ductal carcinoma in situ (DCIS) ≤ 3 cm. Rates of recurrence at any site were evaluated. RESULTS: Median follow-up was 3 years. There were 3 IBTR (2.8%) at a median of 3.2 years. The 3-year actuarial IBTR rate was 1.8%. Patients with ER-negative invasive cancers had a higher IBTR rate compared with ER-positive patients (11.8% vs. 2.2%), although this did not reach statistical significance (P = 0.18). There were no IBTR in 46 patients with DCIS. On univariate analysis, there was no association between "cautionary" criteria and risk of local, regional, or distant recurrence. CONCLUSIONS: Patients considered "cautionary" for APBI based on ASTRO guidelines had low rates of IBTR. ER-negative patients trended toward a higher IBTR rate with APBI compared with ER-positive patients. Longer follow-up is needed to establish the safety of APBI in "cautionary" patients.

Association between blood pressure levels and cognitive impairment in older women: a prospective analysis of the Women's Health Initiative Memory Study.

BACKGROUND: Whether blood pressure (BP), and at what level of controlled BP, reduces risk of cognitive impairment remains uncertain. We investigated the association of BP and hypertension treatment status with mild cognitive impairment and dementia in older women. METHODS: We prospectively analysed a sample of 7207 community-dwelling women aged 65-79 years participating in the Women's Health Initiative Memory Study (WHIMS). Participants were recruited between May 28, 1996, and Dec 13, 1999, at 39 US clinical centres, and they were followed up until Dec 31, 2019. Cognitive function was assessed annually. Mild cognitive impairment and probable dementia were defined through a centralised adjudication process. BP was measured by trained and certified staff at baseline. Pulse pressure (PP) was calculated as systolic BP (SBP) minus diastolic BP. Hypertension was defined using the American Heart Association 2017 Guideline for High BP in Adults. Outcomes were (1) mild cognitive impairment, (2) probable dementia, and (3) cognitive loss (the combined endpoint of either mild cognitive impairment or probable dementia, or both). We estimated hazard ratios (HRs) to assess the association between hypertension, SBP, and PP with the risk of study outcomes using Cox proportional hazards regression models, with adjustment for key covariates. FINDINGS: During a median follow-up of 9 years (IQR 6-15), 1132 (15·7%) participants were classified as mild cognitive impairment, 739 (10·3%) as probable dementia, and 1533 (21·3%) as cognitive loss. The incidence rates per 1000 person-years were 15·3 cases (95% CI 14·4-16·2) for mild cognitive impairment, 9·7 cases (9·0-10·4) for probable dementia, and 20·3 (19·3-21·3) for cognitive loss. Elevated SBP and PP were significantly associated with increased risk of mild cognitive impairment and cognitive loss (test for trends across SBP and PP strata, p<0·01). Individuals with hypertension, but with controlled SBP of less than 120 mm Hg did not have a significantly increased risk of mild cognitive impairment (HR 1·33, 95% CI 0·98-1·82, p=0·071), and of cognitive loss (1·09, 0·82-1·44, p=0·57) compared with normotension. Individuals on anti-hypertensive treatment with PP of less than 50 mm Hg did not have a significantly higher risk of mild cognitive impairment (1·26, 0·98-1·62, p=0·07) and of cognitive loss (1·17, 0·94-1·46, p=0·16). There were no significant associations between hypertension, SBP, or PP and probable dementia. INTERPRETATION: Results of our study show significant associations of hypertension and elevated SBP and PP levels with risk of mild cognitive impairment and the combined endpoint of either mild cognitive impairment or probable dementia, suggesting that intensive control of hypertension, SBP, and PP can preserve cognitive health in older women. FUNDING: National Heart, Lung, and Blood Institute, National Institutes of Health, and US Department of Health and Human Services.

Weight-based loading of vancomycin in patients on hemodialysis.

We evaluated weight-based loading doses of vancomycin and resulting initial prehemodialysis concentrations. Modeling demonstrated modest correlation between dose administered, age, and initial concentration achieved. Actual body weight-based loading of vancomycin predictably achieves therapeutic initial concentrations in patients who receive hemodialysis.

Impact of diabetes mellitus and cardiometabolic syndrome on the risk of Alzheimer's disease among postmenopausal women.

BACKGROUND: In spite of an increase in the incidence and prevalence of diabetes mellitus (DM) and Alzheimer's disease (AD) in the aging population worldwide, limited attention has been paid to their potential association. AIM: To investigate the association of DM and cardiometabolic syndrome (CMS, a precursor to DM) with risk of incident AD among postmenopausal women. METHODS: Postmenopausal women aged 50-79 (n = 63117) who participated in the U.S. Women's Health Initiative Observational Study (WHIOS), recruited in 1993-1998, without baseline AD and followed up through March 1, 2019, were analyzed. AD was classified by participant-reported history of doctor-diagnosis of incident AD in the WHIOS. DM was defined by participant-report or treated because of diabetes or serum glucose concentrations ≥ 126 mg/dL. CMS was defined as having ≥ 3 of five CMS components: large waist circumference, high blood pressure, elevated triglycerides, elevated glucose, and low high-density lipoprotein cholesterol. The associations of DM and CMS with AD were analyzed using Cox's proportional hazards regression analysis. RESULTS: During a median follow-up of 20 years (range: 3.36 to 23.36 years), of 63117 participants, 8340 developed incident AD. Women with DM had significantly higher incidence of AD [8.5, 95% confidence interval (CI): 8.0-9.0 per 1000 person-years (PY)] than those without DM (7.1, 95%CI: 6.9-7.2 per 1000 PY). Multivariate Cox's regression analysis indicated that women with DM or CMS had a significantly higher risk of AD than those without DM or CMS. The corresponding hazard ratios [HR (95%CI)] were 1.22 (1.13-1.31, P < 0.001) in subjects with DM, and 1.18 (1.09-1.27, P < 0.001) in subjects with CMS. The HRs diminished with age and became non-significant in the oldest age group. CONCLUSION: During a median follow-up of 20 years, DM and CMS were significantly associated with the risk of AD among postmenopausal women. More specifically, women aged 50-69 with DM or CMS vs those without these conditions had significantly higher relative risks of AD than the relative risks of AD in those aged 70-79 with DM or CMS vs those without DM or CMS.

Sequence of Pelvic Examination Does Not Affect Patients With Baseline Vulvovaginal Syndromes: A Randomized Clinical Trial.

OBJECTIVE: The purpose of this study is to determine the optimal sequence in performing a pelvic examination to reduce discomfort in patients with baseline vaginal pain. METHODS: A randomized controlled trial of women presenting for a new appointment at the Drexel Vaginitis Center was conducted. Women were assigned to either group A, a Q-tip touch test, speculum examination, then bimanual examination, or group B, a Q-tip touch test, bimanual examination, then speculum examination. The primary outcome was visual analog scales to assess pain at baseline and after each portion of the examination. Secondary outcomes were responses to questionnaires for self-esteem, quality of life, and sexual function. RESULTS: Two hundred women were enrolled in the trial. For both group A and group B, each portion of the examination was similarly scored regardless of whether the speculum examination was performed before or after bimanual examination. Pain during the speculum examination was higher than pain during the other components of the examination, although not significant (P = 0.65).When looking at reported pain outcomes, outcomes did not differ as a whole or between groups in relation to sexual activity, sexual orientation, and previous hysterectomy. The data were not significantly different between groups for self-esteem scores, sexual dysfunction, or quality of life scores. CONCLUSION: In women with baseline vaginal pain, there was no difference in pain scores between the different components of the pelvic examination, nor is there a significant difference in pain during the examination compared with their baseline pain. Most patients reported minimal pain during each component.

Smoking Cessation Counseling in the Inpatient Unit: A Survey of Pediatric Hospitalists.

OBJECTIVES: To determine practices and beliefs of pediatric hospitalists regarding smoking cessation counseling for caregivers of hospitalized children. METHODS: An electronic survey was distributed to 249 members of the Pediatric Research in Inpatient Settings Network over 6 weeks in 2017 (83 responses [33%]). Questions explored beliefs regarding the impact of tobacco smoke exposure (TSE) and practices in TSE screening, provision of counseling, resources, and pharmacotherapy. Nonparametric tests were used to compare groups on numeric variables, χ2 tests were used to compare groups on nominal variables, and McNemar's test was used to compare dichotomous responses within subjects. RESULTS: All respondents were familiar with the term "secondhand smoke," and >75% were familiar with "thirdhand smoke" (THS). Familiarity with THS was associated with more recent completion of training (P = .04). Former smokers (7%) were less likely to agree that THS has a significant impact on a child's health (P = .04). Hospitalists ask about TSE more often than they provide counseling, resources, or pharmacotherapy to caregivers who want to quit smoking. Hospitalists are more likely to ask about TSE and provide cessation counseling when patients have asthma as opposed to other diseases. Time was identified by 41% of respondents as a barrier for providing counseling and by 26% of respondents as a barrier for providing resources. Most respondents never prescribe pharmacotherapy (72%), nor do they follow-up with caregivers after hospitalization regarding cessation (87%). CONCLUSIONS: Although most respondents ask about TSE, opportunities are missed for counseling and providing support to caregivers who want to quit smoking. Providers should be educated about THS, and systems should be streamlined to facilitate brief counseling sessions.
