What women want: A mixed-methods study of women's health priorities, preferences, and experiences in care in three Rwandan rural districts

OBJECTIVE

To explore Rwandan women's experiences, priorities, and preferences in accessing health care for non-pregnancy-related conditions and inform development of healthcare services related to these conditions among women of reproductive age at district hospitals and health centers in Rwanda.

METHODS

We used a mixed-methods, exploratory sequential design. Semi-structured qualitative interviews were conducted with Rwandan women and coded thematically. A cross-sectional quantitative survey based on the qualitative data was administered to women attending health centers.

RESULTS

Seventeen interviews and 150 surveys were conducted. Women identified conditions including back pain, gynecologic cancers, and abnormal vaginal bleeding as concerns. They generally reported positive experiences while accessing health care and knowledge of accessing health care. Barriers to care were identified, including transportation costs and inability to miss work. Women expressed a desire for more control over their care and the importance of maintaining their dignity while accessing health care.

CONCLUSION

These findings provide useful insights to inform development of non-pregnancy-related healthcare services for women in Rwanda according to their priorities and preferences. The reported end-user health concerns, barriers to care, and diminished control over their care point to a need to evolve health systems around user-tailored needs and design interventions optimizing access whilst promoting dignified care.

Manipulating the Wnt/β-catenin signaling pathway to promote anti-tumor immune infiltration into the TME to sensitize ovarian cancer to ICB therapy

OBJECTIVE

Immune checkpoint blockade (ICB) therapy shows limited efficacy in ovarian cancers due to the "cold" immune phenotype surrounding these tumors. Previous studies have shown that in ovarian cancer Wnt/β-catenin pathway activation contributes to this immune phenotype. Here, we evaluated the anti-tumor and immune-enhancing properties of the Wnt inhibitor, CGX-1321, used alone or in combination with either DKN-01 or anti-PD-1 therapy, in pre-clinical ovarian cancer models.

METHODS

The parental ID8 murine ovarian cancer model harboring a knock-out of p53 (ID8p53^-/-) and MISIIR-Tag spontaneous ovarian cancer models were used to test the effects of CGX-1321 alone or in combination therapies on tumor burden and immune cell landscape in the tumor microenvironment (TME). Flow cytometry and NanoString analyses were used to characterize the changes in tumor-intrinsic signaling and immune-related profiles in the TME of ovarian cancer in response to treatments.

RESULTS

CGX-1321 significantly reduced tumor burden and constrained tumor progression in the ID8p53^-/- and MISIIR-Tag models. Furthermore, CGX-1321 increased infiltrating CD8+ T cells in the TME. Combining CGX-1321 with either DKN-01 or anti-PD-1 therapy also decreased tumor burden and increased CD8+ T cell infiltration in the omentum TME but did not do so to a greater extent that CGX-1321 monotherapy.

CONCLUSIONS

CGX-1321 significantly reduced tumor burden and enhanced CD8+ T cell levels in ovarian cancer, nevertheless the addition of DKN-01 or anti-PD-1 therapies did not enhance these effects of CGX-1321. Further investigation is needed to determine if CGX-1321 + DKN-01 combination treatment sensitizes pre-clinical ovarian cancer to ICB therapy.

Relations between Personality Measures and Physiological Reactivity Using a Perceptual Motor Challenge

60 undergraduates participated in research designed to investigate the relations between psychological and physiological measures of personality under stress. Psychological assessments were elicited from responses to the Jenkins Activity Survey. Physiological assessments were elicited during 5 1-min. trials on the pursuit rotor, a perceptual motor task. Pearson correlations and multiple regression analyses were consistent with the notion that psychological and physiological assessments yield contradictory information and that research is needed to develop valid methodologies with which to assess human stress.

Collaborations in gynecologic oncology education and research in low- and middle- income countries: Current status, barriers and opportunities

Eighty-five percent of the incidents and deaths from cervical cancer occur in low and middle income countries. In many of these countries, this is the most common cancer in women. The survivals of the women with gynecologic cancers are hampered by the paucity of prevention, screening, treatment facilities and gynecologic oncology providers. Increasing efforts dedicated to improving education and research in these countries have been provided by international organizations. We describe here the existing educational and research programs that are offered by major international organizations, the barriers and opportunities provided by these collaborations and hope to improve the outcomes of cervical cancer through these efforts.

Beware of the isolated intermediate quality measure: A lesson in choosing an ovarian cancer surgeon

6546

Background: Measuring surgical quality has recently focused on isolated processes (such as P4P measures) and intermediate outcomes (such as infection rates). Some have argued that such isolated measures are inherently flawed since they may have only minor influence on more important primary outcomes such as survival. Hence, referral decisions based on such isolated processes or intermediate outcomes may lead to less than optimal care. We asked whether surgeon type influenced isolated process measures (longer operative time, thought to be a function of increased node sampling), intermediate outcomes (deep wound infection, often found to be a function of operative time) and the primary outcome of survival. Methods: We obtained SEER-Medicare claims for the years 1991–2001 for ovarian cancer. We identified the first definitive cancer surgery and the surgical provider type for that procedure: General Surgeon (GS) N=545 and GYN Oncologist (GO) N=1,554. We determined operative time from the anesthesia claims, number of nodes sampled from the SEER record, deep wound infection from the ICD9CM secondary diagnoses and survival from Medicare vital status files. Models were adjusted for 30 patient characteristics and comorbidities. To account for potential reclassification bias due to variations in the pattern of node dissection across GO and GS surgical types, which can potentially influence stage identification, we report survival results both with and without stage adjustments. Results: Definitive surgery by GOs was associated with more extensive node dissection and longer operative time. GO patients also displayed a trend for increased deep wound infection as compared to cases operated on by GS. However, 5-year survival was significantly longer in the GO group, with or without stage adjustment. Conclusions: GO cases took longer, tended to have higher infection rates, yet had better overall 5-year survival. Isolated intermediate outcome measures, such as deep wound infection, may not be good quality indicators.

Prevalence and incidence of adults consulting for shoulder conditions in UK primary care; patterns of diagnosis and referral

OBJECTIVES

To estimate the national prevalence and incidence of adults consulting for a shoulder condition and to investigate patterns of diagnosis, treatment, consultation and referral 3 yr after initial presentation.

METHODS

Prevalence and incidence rates were estimated for 658469 patients aged 18 and over in the year 2000 using a primary care database, the IMS Disease Analyzer-Mediplus UK. A cohort of 9215 incident cases was followed-up prospectively for 3 yr beyond the initial consultation.

RESULTS

The annual prevalence and incidence of people consulting for a shoulder condition was 2.36% [95% confidence interval (CI) 2.32-2.40%] and 1.47% (95% CI 1.44-1.50%), respectively. Prevalence increased linearly with age whilst incidence peaked at around 50 yr then remained static at around 2%. Around half of the incident cases consulted once only, while 13.6% were still consulting with a shoulder problem during the third year of follow-up. During the 3 yr following initial presentation, 22.4% of patients were referred to secondary care, 30.8% were prescribed non-steroidal anti-inflammatory drugs and 10.6% were given an injection by their general practitioner (GP). GPs tended to use a limited number of generalized codes when recording a diagnosis; just five of 426 possible Read codes relating to shoulder conditions accounted for 74.6% of the diagnoses of new cases recorded by GPs.

CONCLUSIONS

The prevalence of people consulting for shoulder problems in primary care is substantially lower than community-based estimates of shoulder pain. Most referrals occur within 3 months of initial presentation, but only a minority of patients are referred to orthopaedic specialists or rheumatologists. GPs may lack confidence in applying precise diagnoses to shoulder conditions.

Assessment of the Lequesne index of severity for osteoarthritis of the hip in an elderly population

OBJECTIVE

To assess the measurement properties of the Lequesne index of severity for osteoarthritis of the hip (LISOH) together with its overall usefulness with reference to the original stated aims.

METHOD

Postal questionnaire was sent to a random sample of 5500 Oxfordshire residents, aged 65 and above. Respondents with hip symptoms at baseline (but without verification of a diagnosis) were sent an identical follow-up questionnaire 12 months later. The questionnaire included a general health section, including the Short Form-36 survey, and a hip section which began with a screening question about hip pain. Respondents who reported having a prolonged episode of hip pain were asked to complete the LISOH.

RESULTS

At baseline, response rate of 66.3% (3341/5039) was obtained from eligible participants; 19.2% (610/3175) of respondents reported having hip pain. Internal reliability (Cronbach's alpha) was 0.84 (95% CI: 0.81-0.86) for all 11 items of the LISOH; however, factor analysis identified two factors (sub-scales): "function and mobility" and "pain and discomfort". Rasch analysis revealed that the two factors were only unidimensional when applied to sub-groups of respondents. Convergent validity of the LISOH was questionable, as the "function and mobility" factor was more highly correlated with SF-36 bodily pain score than was the "pain and discomfort" factor. The assessment of sensitivity over time was problematic due to changing patterns of symptomatic weight-bearing joints over time.

CONCLUSIONS

The current study identifies major limitations with the LISOH--particularly if used as a single composite measure.

Epidemiology of hip and knee pain and its impact on overall health status in older adults

OBJECTIVES

To obtain prevalence rates of hip and knee pain in elderly people and compare combinations of symptoms with overall health status.

METHODS

We performed a cross-sectional postal survey of a random sample of 5500 Oxfordshire residents aged 65 yr and older. Prevalence estimates were based on the screening question: 'During the past 12 months, have you had pain in or around either of your hip/knee joints on most days for one month or longer?' Overall health status was assessed with the SF-36 questionnaire.

RESULTS

The response rate was 66.3% (3341/5039 eligible people), and was highest (approximately reverse similar 72%) for the 65-74 yr age-group. The percentage reporting hip pain was 19.2% [95% confidence interval (CI) 17.9-20.6], and 32.6% (95% CI 31.0-34.3) reported knee pain. The percentage reporting hip and knee pain was 11.3%, and 40.7% reported hip or knee pain. Less than half (48%) of the symptomatic respondents had unilateral problems affecting one hip or knee joint only. SF-36 scores worsened as the number of symptomatic hip and knee joints increased (P<0.001 for physical function, physical role limitation and bodily pain).

CONCLUSIONS

Patterns of hip and knee symptoms are complex in older people. Amongst the symptomatic, most have more than one hip/knee affected. This has implications for treatment and health status measurement. In the absence of hip and knee symptoms, general health status scores of elderly people are similar to those of people aged under 65 yr.

Synthesis of thiophene-2-carboxamidines containing 2-aminothiazoles and their biological evaluation as urokinase inhibitors

The serine protease urokinase (uPa) has been implicated in the progression of both breast and prostate cancer. Utilizing structure based design, the synthesis of a series of substituted 4-[2-amino-1,3-thiazolyl]-thiophene-2-carboxamidines is described. Further optimization of this series by substitution of the terminal amine yielded urokinase inhibitors with excellent activities.

Rehabilitation of ten soldiers with exertional rhabdomyolysis

This case study describes the rehabilitation of 10 active duty U.S. soldiers with exertional rhabdomyolysis. The pathophysiology of rhabdomyolysis is discussed. The initial management is concerned with accurate diagnosis and monitoring of laboratory values to prevent complications. Active and passive range of motion, strength, and induration were used as indicators of recovery. The goal of rehabilitation was to safely return patients to their basic training units without activity restrictions as quickly as possible. All 10 soldiers were able to pass the Army Physical Fitness Test at the end of their training cycle. For those patients with rhabdomyolysis who desire to return to a high level of function, close monitoring of exercise intensity appears to allow for a safe, expedient return to previous levels of function. This description of a rare disorder will increase awareness and stimulate discussion so that more specific guidelines for rehabilitation can be developed.

Intracellular Localization and intercellular heterogeneity of the human DNA repair protein O(6)-methylguanine-DNA methyltransferase

O(6)-Methylguanine-DNA methyltransferase (MGMT) is a DNA repair protein that removes alkyl adducts from DNA and may be important in tumor resistance to alkylation chemotherapy. MGMT was visualized in human cells and tumor tissues with monoclonal antibodies against MGMT and immunofluorescence microscopy, and fluorescent signals were quantified by digital image analysis. MGMT was found both in the cytoplasm and the nucleus, and in either locale the protein reacts with alkylated DNA bases and becomes inactivated and lost from the cell. Cell lines in culture and xenografts showed a broad normal distribution of nuclear MGMT levels, but human brain tumors often showed a skewed distribution, with a significant fraction of cells with high levels of MGMT. O(6)-Benzylguanine, a suicide substrate inactivator for MGMT activity, reduced MGMT in human cells and in a mouse xenograft to levels undetectable by antibody assay 1 h post-treatment. In melanoma specimens taken from a patient 3 h post-treatment with temozolomide, MGMT levels were reduced by 70%. This quantitative immunofluorescence assay can be used to monitor MGMT and it depletion in human tumors to improve the use of alkylating agents in cancer chemotherapy.

Retrospective study of the correlation between the DNA repair protein alkyltransferase and survival of brain tumor patients treated with carmustine

We tested the hypothesis that the level of the DNA repair protein O6-alkylguanine-DNA alkyltransferase in brain tumors was correlated with resistance to carmustine (BCNU) chemotherapy. Alkyltransferase levels in individual cells in sections from 167 primary brain tumors treated with BCNU were quantitated with an immunofluorescence assay using monoclonal antibodies against human alkyltransferase. Patients with high levels of alkyltransferase had shorter time to treatment failure (P = 0.05) and death (P = 0.004) and a death rate 1.7 times greater than patients with low alkyltransferase levels. Furthermore, the size of the subpopulation of cells with high levels of alkyltransferase was correlated directly with drug resistance. For all tumors the variables most closely correlated with survival, in order of importance, were age, tumor grade, and alkyltransferase levels. For glioblastoma multiforme, survival was more strongly correlated with alkyltransferase levels than with age. These results should encourage prospective studies to evaluate alkyltransferase levels as a method, for identifying brain tumor patients with the best likelihood of response to BCNU chemotherapy.

Glenoid dysplasia

Athletic trainers evaluate many athletes with acute and chronic shoulder problems such as rotator cuff pathology, impingement syndromes, and inflammatory conditions. They also need to be aware of more obscure reasons for shoulder pain and dysfunction. The purpose of this paper is to describe a rare congenital abnormality called glenoid dysplasia, which can be responsible for a variety of shoulder complaints in athletes. Characteristics of glenoid dysplasia are seen on radiographs and include a shallow glenoid fossa and a hypoplastic scapular neck. This case study depicts an athlete who functioned at a very high level for many years before developing symptoms. This athlete was able to continue an active lifestyle but some limitations were recommended.
