Job stressors in relation to burnout and compromised sleep among academic physicians in India.

BACKGROUND: Burnout among physicians, especially in the academic setting, is an urgent concern, with adequate sleep one of the key focal points. OBJECTIVE: To identify job stressors contributing to burnout and compromised sleep among academic physicians, using a comprehensive, theory-based instrument, the Occupational Stressor Index (OSI), whose specific form was created 'for physicians by physicians'. METHODS: This parallel mixed-methods cross-sectional investigation was conducted among 109 physicians employed in a public teaching hospital, Jodhpur, India. Work conditions were evaluated by the physician-specific OSI (part I). The Copenhagen Burnout Index and Pittsburgh Sleep Quality Index (PSQI) were the outcome instruments (part II). Seventy-six physicians completed parts I and II. RESULTS: The physicians were from wide-ranging specialties, and 82% of the cohort were residents. Mean total OSI scores were 87.4±8.1, with unit-change yielding adjusted odds-ratios (95% confidence-intervals) for personal (1.10 (1.02-1.18)) and work-related burnout (1.12 (1.04-1.22)), and PSQI (1.09 (1.01-1.17)). Significant multivariable associations with burnout and/or sleep indices included: working 7 days/week, lacking work-free vacation, insufficient rest breaks, interruptions, many patients in intensive-care, no separate time for non-clinical duties, pressure to publish, injury/suicide attempts of colleagues/staff, performing pointless tasks. The latter were described as administrative/clerical. Lacking genuine rest breaks was mainly patient-related, further compromised by emergency work and lacking separate time for non-clinical duties. Long workhours and exhausting schedule were cited as most difficult parts of work, while reducing workhours, improving work schedule, and hiring more staff most frequently recommended. CONCLUSION: Specific working conditions potentially contributory to burnout and compromised sleep among physicians working in academic medicine are identified using a methodologically-rigorous, in-depth approach. These findings inform evidence-based interventions aimed at preserving physician mental health and work capacity.

Job stressors and burnout among nurses and primary-care physicians working at a dedicated outpatient respiratory center for patients with suspected or confirmed COVID-19.

BACKGROUND: High burnout is reported among health professionals providing in-patient care to patients with coronavirus disease 2019 (COVID-19). Data are lacking on job stressors and burnout among health providers working in dedicated outpatient facilities for patients with suspected or confirmed COVID-19. METHODS: This cross-sectional study, using a parallel mixed-methods design, was carried out in 2021-2022 among 22 nurses and 22 primary-care physicians working at a COVID Outpatient Respiratory Center (CORC) (100% participation). Work conditions were assessed via the nurse- and physician-specific Occupational Stressor Index (OSI) and occupational records. Measures of the outcome included the Copenhagen Burnout Index and current tobacco use. RESULTS: Time working in CORC displayed significant multivariate associations with personal, work- and patient-related burnout among physicians and current tobacco use among nurses. Total OSI scores showed adjusted odds ratios for work-related (1.35 (1.01 ± 1.79))(1.31 (0.99 ± 1.75)) and patient-related burnout (1.35 (1.01 ± 1.81))(1.34 (1.01 ± 1.78)) among physicians and nurses, respectively. Numerous work stressors showed significant multivariate associations with burnout and smoking. Among the stressors were: being contacted outside work hours about patients, inadequate rest breaks, many patients/shifts, difficulty taking time off, insufficient pay, frequently listening to emotionally disturbing accounts, interruptions, increased workload, time pressure, and responsibility. Heavy patient burden/time pressure was most often cited as the hardest part of work in CORC. Increased employment of staff was the most frequently suggested workplace modification. Integrative assessment reveals that increased staff could ameliorate many work stressors associated with burnout and smoking in this cohort. CONCLUSIONS: Working in CORC is an extra burden. In crisis situations such as the COVID pandemic, more staff is needed. Lowering the total job stressor load is vital.

Predictors of treatment failure for adenocarcinoma in situ of the uterine cervix: Up to 14 years of recorded follow-up.

The incidence of adenocarcinoma-in-situ (AIS) of the uterine cervix is rising, with invasive adenocarcinoma becoming increasingly common relative to squamous cell carcinoma. The present study reviewed a cohort of 84 patients first-time treated by conization for histologically-confirmed AIS from January 2001 to January 2017, to identify risk factors associated with recurrent/persistent AIS as well as progression to invasive cervical cancer. Nearly 80% of the patients were age 40 or younger at conization. Endocervical and ectocervical margins were deemed clear in 42 of the patients. All but two patients had ≥1 follow-up, with post-conization high-risk human papilloma virus (HPV) results documented in 52 patients. Altogether, 12 histopathologically-confirmed recurrences (14.3%) were detected; two of these patients had microinvasive or invasive carcinoma. In three other patients cytology showed AIS, but without recorded histopathology. Eight patients underwent hysterectomy for incomplete resection very soon after primary conization; they were not included in bivariate or multivariate analyses. Having ≥1 post-follow-up positive HPV finding yielded the highest sensitivity for histologically-confirmed recurrence: 87.5 [95% confidence interval (CI) 47.4-99.7]. Current or historical smoking status provided highest specificity: 94.4 (95% CI 72.7-99.9) and overall accuracy: 88.0 (95% CI 68.8-97.5) for histologically-confirmed recurrence. With multiple logistic regression (MLR), adjusting for age at conization and abnormal follow-up cytology, positive HPV18 was the strongest predictor of histologically-confirmed recurrence (P<0.005). Having ≥2 positive HPV results also predicted recurrence (P<0.02). Any unclear margin yielded an odds ratio 7.21 (95% CI 1.34-38.7) for histologically-confirmed recurrence adjusting for age, but became non-significant when including abnormal cytology in the MLR model. The strong predictive value of HPV, particularly HPV18 and persistent HPV positivity vis-à-vis detected recurrence indicated that regular HPV testing for patients treated for AIS is imperative. In conclusion, furthering a participatory approach, including attention to smoking with encouragement to attend needed long-term follow-up, can better protect these patients at high risk for cervical cancer.

Age, margin status, high-risk human papillomavirus and cytology independently predict recurrent high-grade cervical intraepithelial neoplasia up to 6 years after treatment.

The present study aimed to identify the factors that independently contribute to disease recurrence among women first-time treated for high-grade cervical intraepithelial neoplasia (CIN) during 4-6 years of follow-up. Overall, 529 of 530 eligible patients participated; these patients all attended a 1st follow-up appointment ~6 months post-conization, at which time high-risk human-papillomavirus (HPV) testing, liquid-based cytology and colposcopy were performed. Full data on margin excision status, other aspects of initial treatment and comorbidity were obtained. At least one subsequent follow-up was attended by 88% of patients. A total of 22 recurrent cases were detected during follow-up. Detected recurrence was the outcome of focus for multiple logistic regression analysis, with odds ratios (OR) and 95% confidence intervals (CI) computed. Four significant independent risk factors were identified: Age 45 years or above (OR=3.5, 95% CI=1.3-9.9), one or both unclear or uncertain margins (OR=5.3, 95% CI=2.0-14.2), positive HPV at 1st follow-up (OR=5.8, 95% CI=2.0-16.8), and abnormal cytology at 1st follow-up (OR=3.9, 95% CI=1.4-11.0). Bivariate analysis revealed that persistent HPV positivity was associated with recurrence (P<0.01). These findings indicated that incomplete excision of the CIN lesion may warrant more intensive subsequent screening, regardless of early post-conization HPV findings. Although early post-conization positive HPV was a powerful, independent predictor of recurrent high-grade CIN, over one-third of the patients with detected recurrence had a negative early post-conization HPV finding. These patients returned for routine screening, at which time, in most cases, HPV status was positive, thus indicating the need for repeated HPV evaluation. Especially during the on-going pandemic, home vaginal self-sampling is recommended. Particular attention is required for women aged ≥45 years. In addition, although not statistically significant, relevant comorbidities, especially autoimmune conditions, warrant consideration in clinical decision-making. Women who have been treated for high-grade CIN are at risk for recurrent disease and progression to cervical cancer; therefore, they require careful, individualized follow-up to avoid these adverse consequences.

Physicians' Total Burden of Occupational Stressors: More than Threefold Increased Odds of Burnout.

OBJECTIVES: To assess the relation between total job stressor burden and physician burnout, identifying potentially contributory modifiable stressors, using a comprehensive, theory-based instrument created for physicians by physicians. METHODS: From 2018 to 2019, we conducted a cross-sectional study in a public teaching hospital in India. Of 305 clinically active physicians, 293 were reached and 42.7% participated. Job stressors were assessed via the physician-specific Occupational Stressor Index (OSI) and burnout by the Copenhagen Burnout Index (CBI). RESULTS: The 76 fully participating physicians were 68% male, 84% residents, and 70% age 30 or younger, from various specialties. Mean scores for total OSI: 87 ± 7.8; personal burnout: 46.6 ± 18.2; work-related burnout: 41.4 ± 20.7; and patient-related burnout: 31.7 ± 22.4. Total OSI scores were significantly associated with personal and work-related burnout, adjusting for working-years as physicians and sex. Total OSI scores >88 showed adjusted odds ratios (±95% confidence intervals): 3.99 (1.31, 12.1) and 6.50 (1.85, 22.8) for personal and work-related burnout, respectively. The high demands aspect of the OSI showed significant multivariate relations to personal, work-related, and patient-related burnout. Patient-related burnout was significantly more likely among male physicians in these multivariate analyses. Physicians outside preventive/diagnostic areas, with heavier burdens and more emergency cases were less likely to fully participate. CONCLUSIONS: The total burden of job stressors is powerfully associated with personal and work-related burnout. The clinically defined total OSI cutpoint >88 warranting urgent intervention is corroborated by >3-fold odds of personal and work-related burnout. Lowering total OSI scores is an immediate priority, starting with potentially modifiable stressors that are already maximum/near-maximum (inadequate rest breaks, nightshifts, work hours, insufficient work-free vacation time, and infection hazards). These issues affect patient care.

Self-sampling for high-risk human papillomavirus as a follow-up alternative after treatment of high-grade cervical intraepithelial neoplasia.

Women treated for high-grade cervical-intraepithelial-neoplasia (CIN) require long-term follow-up with high-risk human-papillomavirus (HPV) testing. Self-sampling for HPV is well-accepted among these patients, but its role in follow-up for this group requires investigation. The present study examined how well HPV findings from self-sampled vaginal (VSS) and urine specimens correctly identified women from this cohort with recurrent CIN2+ compared with samples collected by clinicians. At 1st post-conization follow-up, 531 patients (99.8% participation) gave urine samples, performed VSS, underwent colposcopy with punch biopsy of visible lesions and clinician-collected cervical sampling for HPV analysis and liquid-based cytology. A total of 113 patients with positive HPV and/or abnormal cytology at 1st follow-up underwent 2nd follow-up. At 1st follow-up, all patients with recurrent CIN3 had positive HPV results by all methods. Clinician sampling and VSS revealed HPV16 positivity in 50% of recurrent cases and urine sampling revealed HPV16 positivity in 25% of recurrent cases. At 2nd follow-up, all 7 newly-detected CIN2/3 recurrences were associated with HPV positivity on VSS and clinician-samples. Only clinician-collected samples detected HPV positivity for two adenocarcinoma-in-situ recurrences, and both were HPV18 positive. A total of 77 patients had abnormal cytology at 1st follow-up, for which HPV positivity via VSS yielded highest sensitivity. The HPV findings were positive from VSS in 12 patients with high-grade squamous-intraepithelial-lesions (HSIL), and 11 patients with HSIL had positive HPV findings in clinician-collected and urine samples. All methods for assessing HPV presence yielded significant age-adjusted odds ratios for predicting abnormal lesions at 1st follow-up. For overall HPV results, Cohen's kappa revealed substantial agreement between VSS and clinician sampling, and moderate agreement between urine and clinician sampling. Clinician sampling and VSS were highly concordant for HPV16. Insofar as the pathology was squamous (not glandular), VSS appeared as sensitive as clinician sampling for HPV in predicting outcome among the present cohort. Since VSS can be performed at home, this option can maximize participation in the required long-term follow-up for these women at high-risk.

Acceptance of Self-Sampling Among Long-Term Cervical Screening Non-Attenders with HPV-Positive Results: Promising Opportunity for Specific Cancer Education.

This study aims to investigate acceptance of vaginal self-sampling for high-risk human papilloma virus (HPV) among long-term screening non-attenders at increased cervical cancer risk and to identify leverage points to promote screening adherence among these women. Forty-three long-term screening non-attenders performed home vaginal self-sampling for HPV, had positive HPV results, and subsequently attended gynecologic examination. Sixteen (37.2%) had high-grade cervical intraepithelial neoplasia (CIN2 or 3), and two had invasive cervical cancer. Forty-one of these women completed a questionnaire concerning Specific Knowledge about HPV, CIN, and cervical cancer, potential barriers to screening and views about self-sampling. Results were compared with 479 women treated for CIN2+ who attended gynecologic follow-up and also performed self-sampling. Significant multivariate predictors of long-term non-attender status compared with referents were low Specific Knowledge, high confidence in self-sampling, and potential barriers-refraining from activity to attend gynecologic examination, needing another's help to attend, and long travel time. Non-attenders citing fear/refraining from gynecologic examination as why they preferred self-sampling significantly more often had lowest Specific Knowledge compared with other non-attenders. All non-attenders could envision themselves doing self-sampling again while only 74% of referents endorsed this statement (p = 0.0003). We conclude that HPV self-sampling is an acceptable option for women at increased cervical cancer risk who have been long-term screening non-attenders. Educational outreach to enhance Specific Knowledge about HPV, CIN and cervical cancer is critical. Those non-attenders who explicitly avoid gynecologic examinations need special attention.

Incomplete excision of cervical intraepithelial neoplasia as a predictor of the risk of recurrent disease-a 16-year follow-up study.

BACKGROUND: Women treated for high-grade cervical intraepithelial neoplasia (grade 2 or 3) are at elevated risk for developing cervical cancer. Suggested factors identifying women at highest risk for recurrence post-therapeutically include incomplete lesion excision, lesion location, size and severity, older age, treatment modality, and presence of high-risk human papilloma virus after treatment. This question has been intensively investigated over decades, but there is still substantial debate as to which of these factors or combination of factors most accurately predict treatment failure. OBJECTIVE: In this study, we examine the long-term risk of residual/recurrent high-grade cervical intraepithelial neoplasia among women previously treated for cervical intraepithelial neoplasia 2/3 and how this varies according to margin status (considering also location), as well as comorbidity (conditions assumed to interact with high-risk human papilloma virus acquisition and/or cervical intraepithelial neoplasia progression), posttreatment presence of high-risk human papilloma virus, and other factors. MATERIALS AND METHODS: This prospective study included 991 women with histopathologically confirmed cervical intraepithelial neoplasia 2/3 who underwent conization in 2000-2007. Information on the primary histopathologic finding, treatment modality, comorbidity, age, and high-risk human papilloma virus status during follow-up, and residual/recurrent high-grade cervical intraepithelial neoplasia was obtained from the Swedish National Cervical Screening Registry and medical records. Cumulative incidence of residual/recurrent high-grade cervical intraepithelial neoplasia was plotted on Kaplan-Meier curves, with determinants assessed by Cox regression. RESULTS: During a median of 10 years and maximum of 16 years of follow-up, 111 patients were diagnosed with residual/recurrent high-grade cervical intraepithelial neoplasia or worse. Women with positive/uncertain margins had a higher risk of residual/recurrent high-grade cervical intraepithelial neoplasia or worse than women with negative margins, adjusting for potential confounders (hazard ratio, 2.67; 95% confidence interval, 1.81-3.93). The risk of residual/recurrent high-grade cervical intraepithelial neoplasia or worse varied by anatomical localization of the margins (endocervical: hazard ratio, 2.72; 95% confidence interval, 1.67-4.41) and both endo- and ectocervical (hazard ratio, 4.98; 95% confidence interval, 2.85-8.71). The risk did not increase significantly when only ectocervical margins were positive or uncertain. The presence of comorbidity (autoimmune disease, human immunodeficiency viral infection, hepatitis B and/or C, malignancy, diabetes, genetic disorder, and/or organ transplant) was also a significant independent predictor of residual/recurrent high-grade cervical intraepithelial neoplasia or worse. In women with positive high-risk human papilloma virus findings during follow-up, the hazard ratio of positive/uncertain margins for recurrent/residual high-grade cervical intraepithelial neoplasia or worse increased significantly compared to that in women with positive high-risk human papilloma virus findings but negative margins. CONCLUSION: Patients with incompletely excised cervical intraepithelial neoplasia 2/3 are at increased risk for residual/recurrent high-grade cervical intraepithelial neoplasia or worse. Margin status combined with high-risk human papilloma virus results and consideration of comorbidity may increase the accuracy for predicting treatment failure.

Impact of the human papillomavirus status on the development of high-grade cervical intraepithelial neoplasia in women negative for intraepithelial lesions or malignancy at the baseline: A 9-year Swedish nested case-control follow-up study.

BACKGROUND: The causal relation between high-risk human papillomavirus (HPV) and cervical cancer and its precursor lesions has led to the use of sensitive HPV molecular tests for screening. This study examined the impact of the baseline HPV status on the future risk of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) among women with cytology negative for intraepithelial lesions or malignancy (NILM). METHODS: This was a nested case-control study including women with NILM baseline cytology participating in the Swedish cervical screening program in 2005-2007. Ninety-six cases of CIN2+ and 5 age-matched controls per case were identified through the National Cervical Screening Registry by follow-up through 2014. Baseline liquid-based cytology samples were tested for HPV. Conditional logistic regression analysis was used to calculate odds ratios (ORs) with confidence intervals (CIs). RESULTS: The risk of future high-grade cervical intraepithelial neoplasia (CIN) was strongly associated with the baseline HPV status. For women younger than 30 years, HPV-16/18 showed a significant association with future risk for CIN2+ (OR, 9.44; 95% CI, 3.37-26.4). Other HPV types were not significantly associated with future CIN2+ in these younger women. For women 30 years old or older, both HPV-16/18 and other HPV subtypes conferred a significant risk. CONCLUSIONS: The presence of HPV-16/18 among women with NILM cytology is associated with an elevated future risk of high-grade CIN. HPV types other than HPV-16/18 seem to have a greater impact on women 30 years old or older than younger women. Women with NILM cytology and HPV-16/18 need specific follow-up management within screening.

Is self-sampling to test for high-risk papillomavirus an acceptable option among women who have been treated for high-grade cervical intraepithelial neoplasia?

OBJECTIVE: Self-sampling to test for high risk human papilloma virus (HPV) is becoming an increasingly important component of cervical cancer screening. The aim of this observational study is to examine how women treated for high-grade cervical intraepithelial neoplasia (CIN) view HPV self-sampling. METHODS: Invited to participate in the present study were patients who had undergone treatment of high-grade CIN (grade 2 or higher) and were followed-up at 6-months at the Karolinska University Hospital, Stockholm. The participants were instructed as to how to perform HPV self-sampling. Thereafter, the participants completed a questionnaire about HPV self-sampling and other cervical cancer screening methods, as well as about self-perceived risk of cervical cancer without regular gynecologic follow-up and about specific knowledge regarding HPV, CIN and cervical cancer. RESULTS: Altogether 479 women enrolled in this study. The participation rate was 96.6%. Nearly 75% of the participants stated they would consider performing the HPV self-sampling prior to their next gynecologic follow-up. Confidence in HPV self-sampling was a significant independent predictor of willingness to perform HPV self-sampling. However, confidence in HPV self-sampling was significantly lower than confidence in Papanicolaou smears and in HPV testing with samples collected by health professionals. Higher specific knowledge about HPV, CIN and cervical cancer was also a significant independent predictor of willingness to perform HPV self-sampling, as was having travelled longer distance to attend gynecologic follow-up. Participants with lower income and without completed university education expressed significantly higher confidence in HPV self-sampling and lower confidence in Papanicolaou smears than the other women. CONCLUSIONS: To the best of our knowledge, this is the first study to examine the views of women treated for high-grade CIN vis-à-vis HPV self-sampling. The latter is an acceptable option for the vast majority of this cohort of women.

Perceived cervical cancer risk among women treated for high-grade cervical intraepithelial neoplasia: The importance of specific knowledge.

OBJECTIVE: Women with high-grade cervical intraepithelial neoplasia (CIN) are at increased risk for developing cervical cancer. We examine how women with high-grade CIN perceive their own risk, and about pertinent knowledge concerning human high-risk papillomavirus (HPV), CIN and cervical cancer. METHODS: All patients who underwent first-time treatment of high-grade CIN (grade 2+) were followed-up at 6-months at the Karolinska University Hospital, Stockholm, Sweden and were invited to participate in the present study. This included completion of a questionnaire examining sociodemographic characteristics, self-perceived risk of cervical cancer without regular gynecologic follow-up, and 14 queries about HPV, CIN and cervical cancer knowledge, inter alia. RESULTS: The participation rate was 96.6%, with 479 women enrolled in this study. Over 75% were age 40 or younger, over half had completed university education. Most were married or co-living with their partner and were gainfully employed. On a scale scored from 10 (highest self-perceived risk of cervical cancer without regular gynecologic follow-up) to 1 (lowest self-perceived risk), 64% rated their risk ≥ 7; almost 30% viewed their risk ≤ 6 and 7.5% did not rate their risk. A Specific Knowledge Scale with six of the queries explained 58.3% of the total variance. Nearly 30% of the women answered four or fewer of the six queries correctly. The Specific Knowledge Scale predicted self-perceived cervical cancer risk (Odds ratio = 11.3, 95% Confidence Interval 5.6 - 22.6) after adjusting for age, income and education. Most of the women with low self-perceived cervical cancer risk did not rate their HPV-related knowledge as good. However, 32 predominantly university-educated women, with low self-perceived cervical cancer risk, considered their HPV-related knowledge good. CONCLUSION: It is vital to effectively convey accurate information about these patients' cervical cancer risk, needed preventive and follow-up measures, together with the relevant specific knowledge, for these women at increased risk for developing cervical cancer. Tailored programming to address these knowledge gaps is needed.

The Challenge of Ovarian Cancer: Steps Toward Early Detection Through Advanced Signal Processing in Magnetic Resonance Spectroscopy.

BACKGROUND: Ovarian cancer is a major cause of cancer death among women worldwide, and particularly in Israel. Although the disease at stage IA has 5 year survival rates of over 90%, early detection methods are not sufficiently accurate. Consequently, ovarian cancer is typically diagnosed late, which results in high fatality rates. An excellent candidate for early ovarian cancer detection would be in vivo magnetic resonance spectroscopy (MRS) because it is non-invasive and free of ionizing radiation. In addition, it potentially identifies metabolic features of cancer. Detecting these metabolic features depends on adequate processing of encoded MRS time signals for reconstructing interpretable information. The conventional Fourier-based method currently used in all clinical scanners is inadequate for this task. Thus, cancerous and benign ovarian lesions are not well distinguished. Advanced signal processing, such as the fast Padé transform (FPT) with high-resolution and clinically reliable quantification, is needed. The effectiveness of the FPT was demonstrated in proof-of-concept studies on noise-controlled MRS data associated with benign and cancerous ovaries. The FPT has now been successfully applied to MRS time signals encoded in vivo from a borderline serous cystic ovarian tumor. Noise was effectively separated out to identify and quantify genuine spectral constituents that are densely packed and often overlapping. Among these spectral constituents are recognized and possible cancer biomarkers including phosphocholine, choline, isoleucine, valine, lactate, threonine, alanine, and myoinositol. Most of these resonances remain undetected with Fourier-based in vivo MRS of the ovary. With Padé optimization, in vivo MRS could become a key method for assessing ovarian lesions, more effectively detecting ovarian cancer early, thereby improving survival for women afflicted with this malignancy.

Imaging surveillance programs for women at high breast cancer risk in Europe: Are women from ethnic minority groups adequately included? (Review).

Women from ethnic minority groups, including immigrants and refugees are reported to have low breast cancer (BC) screening rates. Active, culturally-sensitive outreach is vital for increasing participation of these women in BC screening programs. Women at high BC risk and who belong to an ethnic minority group are of special concern. Such women could benefit from ongoing trials aimed at optimizing screening strategies for early BC detection among those at increased BC risk. Considering the marked disparities in BC survival in Europe and its enormous and dynamic ethnic diversity, these issues are extremely timely for Europe. We systematically reviewed the literature concerning European surveillance studies that had imaging in the protocol and that targeted women at high BC risk. The aim of the present review was thereby to assess the likelihood that women at high BC risk from minority ethnic groups were adequately included in these surveillance programs. Twenty-seven research groups in Europe reported on their imaging surveillance programs for women at increased BC risk. The benefit of strategies such as inclusion of magnetic resonance imaging and/or more intensive screening was clearly documented for the participating women at increased BC risk. However, none of the reports indicated that sufficient outreach was performed to ensure that women at increased BC risk from minority ethnic groups were adequately included in these surveillance programs. On the basis of this systematic review, we conclude that the specific screening needs of ethnic minority women at increased BC risk have not yet been met in Europe. Active, culturally-sensitive outreach is needed to identify minority women at increased BC risk and to facilitate their inclusion in on-going surveillance programs. It is anticipated that these efforts would be most effective if coordinated with the development of European-wide, population-based approaches to BC screening.

Proof-of-the-Concept Study on Mathematically Optimized Magnetic Resonance Spectroscopy for Breast Cancer Diagnostics.

Magnetic resonance (MR)-based modalities aid breast cancer detection without exposure to ionizing radiation. Magnetic resonance imaging is very sensitive but costly and insufficiently specific. Molecular imaging through magnetic resonance spectroscopy (MRS) can provide information about key metabolites. Here, the measured/encoded time signals cannot be interpreted directly, necessitating mathematics for mapping to the more manageable frequency domain. Conventional applications of MRS are hampered by data analysis via the fast Fourier transform (FFT) and postprocessing by fitting techniques. Most in vivo MRS studies on breast cancer rely upon estimations of total choline (tCHO). These have yielded only incremental improvements in diagnostic accuracy. In vitro studies reveal richer metabolic information for identifying breast cancer, particularly in closely overlapping components of tCHO. Among these are phosphocholine (PC), a marker of malignant transformation of the breast. The FFT cannot assess these congested spectral components. This can be done by the fast Padé transform (FPT), a high-resolution, quantification-equipped method, which we presently apply to noisy MRS time signals consistent with those encoded in breast cancer. The FPT unequivocally and robustly extracted the concentrations of all physical metabolites, including PC. In sharp contrast, the FFT produced a rough envelope spectrum with a few distorted peaks and key metabolites absent altogether. As such, the FFT has poor resolution for these typical MRS time signals from breast cancer. Hence, based on Fourier-estimated envelope spectra, tCHO estimates are unreliable. Using even truncated time signals, the FPT clearly distinguishes noise from true metabolites whose concentrations are accurately extracted. The high resolution of the FPT translates directly into shortened examination time of the patient. These capabilities strongly suggest that by applying the FPT to time signals encoded in vivo from the breast, MRS will, at last, fulfill its potential to become a clinically reliable, cost-effective method for breast cancer detection, including screening/surveillance.

Why are job stressors relevant for psychiatry?

Work-related mental health disorders are a major public health problem. Consequently, psychiatrists encounter many patients whose clinical state is profoundly affected by work conditions. Psychiatrists therefore, need training in occupational/stress medicine. This would help integrate health services for these patients, aimed at preservation of work fitness and mental health.

Occupational medicine--then and now: where we could go from here.

Occupational medicine has a long-standing history in the region of the former Yugoslavia with seminal contributions to the theory and practice of this discipline. This tradition should be expanded to incorporate psychosocial stressors. We review the sociological work stress models and empirical evidence gleaned thereby, and then the occupational stressor index, an additive burden model developed from a cognitive ergonomics perspective. In numerous studies, the occupational stressor index is significantly associated with risk behaviors: smoking, obesity and sedentariness and clinical outcomes: hypertension, ischemic heart disease, dyslipidemia and type 2 diabetes. The occupational stressor index characterizes the work conditions of physicians including surgeons and anesthesiologists; professional drivers and other groups at elevated risk for stress-related disorders. Much of these empirical data are from this region. Work-stress related health disorders are a major public health problem, with enormous human and economic costs. A more proactive role for physicians is needed vis-à-vis our working environment and that of patients. We physicians face a heavy job stressor burden strongly implicated with adverse health outcomes. The challenge is to identify effective strategies to lower the risk of work-stressor related illness. The critical gap is the lack of evidence-based guidelines. Intervention studies are needed in which job stressors are ameliorated as a therapeutic/preventive modality; the logical starting point is within our own profession. We also suggest how the relevant clinical competence could be enhanced. Alongside clinical enhancement should be the full restoration of physician empowerment to implement work-related recommendations. A participatory action research perspective by physicians for physicians and for our patients is needed.

Acceptance of human papillomavirus (HPV) vaccination among young women in a country with a high prevalence of HPV infection.

Cervical cancer is the second most common cancer among women in Argentina and the mortality has remained unchanged for the last 30 years. The 2011 national implementation of human papillomavirus (HPV) vaccination will be a key component of future cervical cancer prevention. Vaccination of young adult women is not included in the program, although these women could also benefit from the vaccine, especially in underserved areas with a high prevalence of HPV. However, research on acceptance of HPV vaccination within this group is scarce. The aim of this study was to investigate acceptance of HPV vaccination, the correlation between acceptance and cost, as well as other factors and perceptions of HPV vaccination among young adult women in Argentina. In total, 174 young women aged 18-30 years were included in this quantitative cross-sectional hospital-based study in a low resource area of the Mendoza Province, conducted through structured questionnaire-based interviews. Multinomial logistic regression models were used to investigate correlates of acceptance. Acceptance of HPV vaccination was high if it was free (95%) and even if it was not (75%). A significant positive association was found between acceptance and belief in vaccine safety (p=0.01) and between acceptance and not being a welfare recipient (p=0.00). Nearly half the participants incorrectly believed that they would be fully protected against cervical cancer after vaccination. Our findings suggest that acceptance of HPV vaccination is high among young women in a high-risk, relatively underserved area, even if vaccination is not free. Extensive misconceptions about the vaccine, however, highlight the need for further education about HPV vaccination.

Molecular imaging in the framework of personalized cancer medicine.

With our increased understanding of cancer cell biology, molecular imaging offers a strategic bridge to oncology. This complements anatomic imaging, particularly magnetic resonance (MR) imaging, which is sensitive but not specific. Among the potential harms of false positive findings is lowered adherence to recommended surveillance post-therapy and by persons at increased cancer risk. Positron emission tomography (PET) plus computerized tomography (CT) is the molecular imaging modality most widely used in oncology. In up to 40% of cases, PET-CT leads to changes in therapeutic management. Newer PET tracers can detect tumor hypoxia, bone metastases in androgen-sensitive prostate cancer, and human epidermal growth factor receptor type 2 (HER2)-expressive tumors. Magnetic resonance spectroscopy provides insight into several metabolites at the same time. Combined with MRI, this yields magnetic resonance spectroscopic imaging (MRSI), which does not entail ionizing radiation and is thus suitable for repeated monitoring. Using advanced signal processing, quantitative information can be gleaned about molecular markers of brain, breast, prostate and other cancers. Radiation oncology has benefited from molecular imaging via PET-CT and MRSI. Advanced mathematical approaches can improve dose planning in stereotactic radiosurgery, stereotactic body radiotherapy and high dose-rate brachytherapy. Molecular imaging will likely impact profoundly on clinical decision making in oncology. Molecular imaging via MR could facilitate early detection especially in persons at high risk for specific cancers.

Why don't academic physicians seek needed professional help for psychological distress?

PURPOSE: Suicidal thoughts, burnout and other signs of psychological distress are prevalent among physicians. There are no studies concerning help-seeking for psychological distress among university hospital physicians, who face a particularly challenging, competitive work environment. We compare psychologically-distressed university hospital physicians who have not sought needed help with those who have sought such help. We thereby aim to identify factors that may hinder help-seeking and factors that may trigger seeking help. METHODS: Analysis was performed among university hospital physicians reporting recent suicidal thoughts and/or showing other indications of current psychological ill-health. These distressed physicians were a subgroup (42.7%) from the cross-sectional phase I HOUPE study (Health and Organization among University Hospital Physicians in Europe): 366 from Sweden and 150 from Italy. Having sought professional help for depression or burnout was the outcome variable. Multiple logistic regression was performed with socio-demographic factors as covariates. RESULTS: Altogether 404 (78.3%) of these distressed physicians had never sought professional help for depression/burnout. Physicians who were currently involved in medical research, taking night call, surgical specialists, male, or Italian were least likely to have sought help. Physicians who faced harassment at work or who self-diagnosed and self-treated were more likely to have sought help. CONCLUSION: Very few of these university hospital physicians with signs of psychological distress sought help from a mental-health professional. This has implications for physicians themselves and for patient care, clinical research, and education of future physicians. More study, preferably of interventional design, is warranted concerning help-seeking among these physicians in need.

Night work, total occupational burden and cancer/cardiovascular risk factors in physicians.

INTRODUCTION. Lifestyle-related risk factors: smoking, obesity, sedentariness and excess alcohol intake are among the most important known causes of cancer and cardiovascular disease. The aim of this study is to examine the relationship between these lifestyle-related risk factors for cancer/cardiovascular disease and working conditions among surgeons/anesthesiologists and other physicians. MATERIAL AND METHODS. The study was carried out among physicians aged 35 to 60, without diagnosed coronary heart disease or other structural heart disease, who were employed at the Novi Sad University Hospital. The participation rate was high (> 90%). The physicians completed the Occupational Stress Index. Low lifestyle-related cancer/cardiovascular risk was defined as: not a current smoker, body mass index < 28, regular recreational physical activity and not consuming alcohol every day. Analysis of covariance was performed. RESULTS. Of 191 physicians included in this study only 23 (12.0%) had a low lifestyle-related cancer/cardiovascular risk. Surgeons/anesthesiologists faced a heavier total work stressor burden than physicians in other profiles (87.7 +/- 8.8 versus 74.1 +/- 10.5, p=0.000). Among the 56 surgeons/anesthesiologists, lower nightshift work scores were associated with low lifestyle-related cancer/cardiovascular risk (F=4.19, p=0.046). A lower overall work stressor burden was associated with low risk among the other 135 physicians (F=4.06, p=0.046). CONCLUSION. Specific workplace intervention strategies are urgently needed. Among the surgeons/anesthesiologists these should include reduction in the frequency of night call and improvement of the overall conditions of nightshift work. Among other physicians, the total occupational burden needs to be diminished.
