Medicine students ,Cancer ,Palliative care ,Oncologists - Abstract
Cancer is one of the most common causes of death all over the World (Rahib et al. in Cancer Res 74(11):2913-2921, 2014; Silbermann et al. in Ann Oncol 23(Suppl 3):iii15-iii28, 2012). It is crucial to diagnose this disease early by effective screening methods and also it is very important to acknowledge the community on various aspects of this disease such as the treatment methods and palliative care. Not only the oncologists but every medical doctor should be educated well in dealing with cancer patients. Previous studies suggested various opinions on the level of oncology education in medical schools (Pavlidis et al. in Ann Oncol 16(5):840-841, 2005). In this study, the perspectives of medical students on cancer, its treatment, palliative care, and the oncologists were analyzed in relation to their educational status. A multicenter survey analysis was performed on a total of 4224 medical school students that accepted to enter this study in Turkey. After the questions about the demographical characteristics of the students, their perspectives on the definition, diagnosis, screening, and treatment methods of cancer and their way of understanding metastatic disease as well as palliative care were analyzed. The questionnaire includes questions with answers and a scoring system of Likert type 5 (absolutely disagree = 1, completely agree = 5). In the last part of the questionnaire, there were some words to detect what the words "cancer" and "oncologist" meant for the students. The participant students were analyzed in two study groups; "group 1" (n = 1.255) were phases I and II students that had never attended an oncology lesson, and "group 2" (n = 2.969) were phases III to VI students that had attended oncology lessons in the medical school. SPSS v17 was used for the database and statistical analyses. A value of p < 0.05 was noted as statistically significant. Group 1 defined cancer as a contagious disease (p = 0.00025), they believed that early diagnosis was never possible (p = 0.042), all people with a diagnosis of cancer would certainly die (p = 0.044), and chemotherapy was not successful in a metastatic disease (p = 0.003) as compared to group 2. The rate of the students that believed gastric cancer screening was a part of the national screening policy was significantly more in group 1 than in group 2 (p = 0.00014). Group 2 had a higher anxiety level for themselves or their family members to become a cancer patient. Most of the students in both groups defined medical oncologists as warriors (57% in group 1 and 40% in group 2; p = 0.097), and cancer was reminding them of "death" (54% in group 1 and 48% in group 2; p = 0.102). This study suggested that oncology education was useful for the students' understanding of cancer and related issues; however, the level of oncology education should be improved in medical schools in Turkey. This would be helpful for medical doctors to cope with many aspects of cancer as a major health care problem in this country.

WOS: 000376904300006, PubMed ID: 27097941, OBJECTIVE: Prostate cancer is among the most common cancers in males. Prostate cancer is androgen dependent in the beginning, but as time progresses, it becomes refractory to androgen deprivation treatment. At this stage, docetaxel has been used as standard treatment for years. Cabazitaxel has become the first chemotherapeutic agent which has been shown to increase survival for patients with metastatic Castrate Resistant Prostate Cancer (mCRPC) that progresses after docetaxel. Phase 3 TROPIC study demonstrated that cabazitaxel prolongs survival. PATIENTS AND METHODS: In this study, we evaluated a total of 103 patients who took cabazitaxel chemotherapy for mCRPC diagnosis in 21 centers of Turkey, retrospectively. This study included patients who progressed despite docetaxel treatments, had ECOG performance score between 0-2, and used cabazitaxel treatment. Patients received cabazitaxel 25 mg/m(2) at every 3 weeks, and prednisolone 5 mg twice a day. RESULTS: Median number of cabazitaxel cures was 5.03 (range: 1-17). Cabazitaxel response evaluation detected that 34% of the patients had a partial response, 22.3% had stable disease and 32% had a progressive disease. Grade 3-4 hematological toxicities were neutropenia (28.2%), neutropenic fever (14.5%), anemia (6.7%), and thrombocytopenia (3.8%). In our study, median progression-free survival (PFS) was 7.7 months and overall survival (OS) was 10.6 months. CONCLUSIONS: This study reflects toxicity profile of Turkish patients as a Caucasian race. We suggest that cabazitaxel is a safe and effective treatment option for mCRPC patients who progress after docetaxel. Moreover, ethnicity may play important roles both in treatment response and in toxicity profile.

Breast Cancer ,Neoadjuvant Chemotherapy ,Tumor Lymphocytic Infiltrates ,Prognosis - Abstract
WOS: 000361421900007 PubMed ID: 26416041 Purpose: The presence of a pronounced tumor lymphocytic infiltrate (TLI) is deemed to reflect the presence of an immunoinflammatory response against the tumor and may thus have prognostic significance. We investigated the prognostic value of TLI detected in pathological specimens collected following neoadjuvant chemotherapy (NACT) in patients with breast cancer. Methods: 100 consecutive patients with breast cancer (mean age 47.8 +/- 11.4 years) who were scheduled to undergo anthracycline- and/or taxane-containing NACT were enrolled. Specimens collected after NACT were scored with the 4-point Klintrup scoring criteria for the presence of TLI. Results: 60 patients had low-grade TLI and 40 high-grade TLI. Comparison of the patient population according to low-grade vs high-grade TLI revealed statistically significant difference both in terms of disease-free survival (DFS) (log rank=4.28, p

Survival ,Albumin ,Gastric carcinoma ,Albumin-globulin ratio ,Predictive - Abstract
Introduction: The potential effects of serum albumin and albumin-globulin rate on survival were investigated in patients with gastric carcinoma. Materials and methods: The biochemical values of 204 patients under chemotherapy evaluation were obtained retrospectively from archive data. Albumin-globulin ratio values were calculated using albumin/total protein-albumin formula. The values of albumin- globulin ratio and albumin were categorized as 3 groups using receiver operating characteristic analysis and a descending order. Results: The calculated cut-off value for albumin-globulin ratio was 1.14: 34.4-79.7 by receiver operating characteristic. The median survival was 20.7 months (15.9-25.5), 20.1 months (15.1-25.1), 16 months (11.8-20.1 ), respectively in 1st, 2nd, 3rt groups for albumin-globulin ratio (p=0.46). The median overall survival was 18.3 months (12.3-24.2), 21.6 months (16.8-26.3), 18.01 months (13.5-22.4) in 1st, 2nd, 3rt groups for albumin, respectively (p=0.52). There were no statistical significant differences by Kaplan- Meier method for albumin-globulin ratio, albumin p > 0.05. The effects of clinicopathological and biochemical characteristics on mortality were assessed by Cox-proportional hazard regression analysis. The independent predictors of mortality were observed high grade, the presence of perineural invasion of the tumor, high nodal involvement (p:0.01, p:0.001, p:0.01), respectively. Conclusion: Albumin-globulin ratio and albumin values alone may not be useful parameters to predict mortality and survival in patients with gastric carcinoma.

Primary thoracic soft tissue sarcoma ,prognostic factors ,treatment - Abstract
BackgroundSoft tissue sarcomas (STSs) are rare malignant tumors of embryogenic mesoderm origin. Primary thoracic STSs account for a small percentage of all STSs and limited published information is available. This study aimed to identify the prognostic factors for thoracic STSs and evaluate the disease's clinical outcomes. MethodsThe medical records of 109 patients with thoracic STSs who were treated between 2003 and 2013 were retrospectively reviewed. Patients' survival rates were analyzed and potential prognostic factors evaluated. ResultsThe median follow-up period was 29 months (range: 1-121 months). STSs were most frequently localized on the chest wall (n = 42; 38.5%) and lungs (n = 42; 38.5%). The most common histological types were malignant fibrous histiocytoma (n = 23; 21.1%), liposarcoma (n = 17; 15.6%), and leiomyosarcoma (n = 16; 14.7%). The median survival time of all patients was 40.3 months (95% confidence interval, 14.22-66.37 months), with one and five-year survival rates of 93.4% and 63.5%, respectively. Univariate analysis of all groups revealed that metastatic stage, unresectability, tumor diameter of >10cm, tumor location other than the chest wall, and grade 3 diseases were predictable of poor survival. However, only grade 3 diseases and tumor location other than the chest wall were confirmed by multivariate analysis as poor prognostic factors. ConclusionsPrimary thoracic STSs are rarely seen malignant tumors. Our results indicated that patients with low-grade tumors and those localized on the chest wall often experienced better survival outcomes.

Aging of population affects all aspects of the society ranging from the healthcare to welfare systems, public finances, family life and LTC issues, as well. Turkey’s population is younger than that of European countries. However, the ageing population is growing rapidly in Turkey As a result of the increase in the aging population, health expenditure and long-term care services needs have swiftly increased, and this increase, as well as becoming a noteworthy situation, has posed a serious threat to Turkey, including the ones having an extremely powerful social security system, for the future. In Turkey, currently there is no long-term care insurance system. The elderly are usually taken care of within their own family. Long-term care infrastructure are extremely scarce. At the same time, home care and social care are least developed in Turkey, with the scarce public supplies being rationed by quantity and treated as last resort options by families and private providers. Public and private support for long-term care for older persons still is not visible and at national level it is often a non-issue. However, in recent years, quite important steps are being taken for long-term care to innovative implemantations has been witnessed. We will point out some good practices about long-term care for older people in Turkey.

Colorectal cancer ,Brain metastasis ,Prognosis - Abstract
Brain metastasis in colorectal cancer is highly rare. In the present study, we aimed to determine the frequency of brain metastasis in colorectal cancer patients and to establish prognostic characteristics of colorectal cancer patients with brain metastasis. In this cross-sectional study, the medical files of colorectal cancer patients with brain metastases who were definitely diagnosed by histopathologically were retrospectively reviewed. Brain metastasis was detected in 2.7 % (n = 133) of 4,864 colorectal cancer patients. The majority of cases were male (53 %), older than 65 years (59 %), with rectum cancer (56 %), a poorly differentiated tumor (70 %); had adenocarcinoma histology (97 %), and metachronous metastasis (86 %); received chemotherapy at least once for metastatic disease before brain metastasis developed (72 %), had progression with lung metastasis before (51 %), and 26 % (n = 31) of patients with extracranial disease at time the diagnosis of brain metastasis had both lung and bone metastases. The mean follow-up duration was 51 months (range 5-92), and the mean survival was 25.8 months (95 % CI 20.4-29.3). Overall survival rates were 81 % in the first year, 42.3 % in the third year, and 15.7 % in the fifth year. In multiple variable analysis, the most important independent risk factor for overall survival was determined as the presence of lung metastasis (HR 1.43, 95 % CI 1.27-4.14; P = 0.012). Brain metastasis develops late in the period of colorectal cancer and prognosis in these patients is poor. However, early screening of brain metastases in patients with lung metastasis may improve survival outcomes with new treatment modalities.

The convergence system includes (1) Senonian pre-collision (subduction) (2) Late Cretaceous syn-collision and (3) post-collisional stages consisting of subdivisions such as (1) Late Cretaceous I-type, CALK hybrid magmatism (11) Late Cretaceous to Paleocene distensional-related, intracrustal A-type intrusives and (III) Middle-Upper Eocene post-collisional, extensional-related, A-type intrusives. The pre-, syn- and post-collisonal granitoids seem to be associated with their proper mineralization in terms of magma genesis and wall-rock maintained by different geodynamics. After amalgamation, sedimentation in Oligo-Miocene transpressional and Mio-Pliocene transtensional basins has induced the widespread sedimentary and volcano-sedimantary sequences accompanied the evaporite deposition in Central Turkey. The hydrothermal consequences of sequential convergence events are well recorded by temporarily and spatially associated mineral deposits in NE and Central Turkey., Soc Geol Appl

PHOSPHORS ,MICROENCAPSULATION ,PHOTOLUMINESCENCE ,ALUMINUM oxide ,CALCIUM sulfate - Abstract
Single-crystal, submicrorneter-sized CaS:Eu luminescentparticles were synthesized via a solvothermal route, and these moisture- sensitive particles were coated with aluminum oxide using atomic layer deposition (ALD). Photoluminescence (PL) spectra of coated and uncoated particles were compared. They both showed a broad-band PL emission with a maximum of 650 nm. Microencapsulation by aluminum oxide layers did not have a pronounced effect on the intensity of the emission. In situ luminescence measurements during the accelerated aging (80°C, 80% relative humidity) of coated and uncoated CaS:Eu particles were performed. While the uncoated phosphor was largely degraded within 30 h of aging, it was observed that a 20 nm thick aluminum oxide coating dramatically increased the resistance of the luminescent material against moisture, showing the conformity of the Al
2 O3 coating by the ALD process. Upon degradation, CaCO3 was formed, leading to Eu3+ emission as observed in cathodoluminescence. Finally, the use of these coated particles as a wavelength conversion material in light-emitting diodes was evaluated. [ABSTRACT FROM AUTHOR]- Published

- Abstract
We studied the persistent luminescence in europium-doped calcium thiosilicate upon codoping with the rare-earth elements neodymium, dysprosium, samarium, and thulium. The strongest afterglow was observed for neodymium codoping. The persistence emission spectrum is dominated by a band at 660nm, which makes the afterglow color redshifted compared to the steady-state luminescence. Thermoluminescence measurements revealed different glow curves for the two europium lattice sites in the Ca2SiS4host, suggesting that transfer of charge carriers via the conduction band is of minor importance. Finally, we conclude that the Nd3+ions occupy lattice sites in close proximity of the Eu2+ions, based on site-selective luminescence measurements on Ca2SiS4:Eu,Nd.

Cancer is one of the most common causes of death all over the World (Rahib et al. in Cancer Res 74(11):2913–2921, 2014; Silbermann et al. in Ann Oncol 23(Suppl 3):iii15–iii28, 2012). It is crucial to diagnose this disease early by effective screening methods and also it is very important to acknowledge the community on various aspects of this disease such as the treatment methods and palliative care. Not only the oncologists but every medical doctor should be educated well in dealing with cancer patients. Previous studies suggested various opinions on the level of oncology education in medical schools (Pavlidis et al. in Ann Oncol 16(5):840–841, 2005). In this study, the perspectives of medical students on cancer, its treatment, palliative care, and the oncologists were analyzed in relation to their educational status. A multicenter survey analysis was performed on a total of 4224 medical school students that accepted to enter this study in Turkey. After the questions about the demographical characteristics of the students, their perspectives on the definition, diagnosis, screening, and treatment methods of cancer and their way of understanding metastatic disease as well as palliative care were analyzed. The questionnaire includes questions with answers and a scoring system of Likert type 5 (absolutely disagree = 1, completely agree = 5). In the last part of the questionnaire, there were some words to detect what the words “cancer” and “oncologist” meant for the students. The participant students were analyzed in two study groups; “group 1” (n = 1.255) were phases I and II students that had never attended an oncology lesson, and “group 2” (n = 2.969) were phases III to VI students that had attended oncology lessons in the medical school. SPSS v17 was used for the database and statistical analyses. A value of p < 0.05 was noted as statistically significant. Group 1 defined cancer as a contagious disease (p = 0.00025), they believed that early diagnosis was never possible (p = 0.042), all people with a diagnosis of cancer would certainly die (p = 0.044), and chemotherapy was not successful in a metastatic disease (p = 0.003) as compared to group 2. The rate of the students that believed gastric cancer screening was a part of the national screening policy was significantly more in group 1 than in group 2 (p = 0.00014). Group 2 had a higher anxiety level for themselves or their family members to become a cancer patient. Most of the students in both groups defined medical oncologists as warriors (57% in group 1 and 40% in group 2; p = 0.097), and cancer was reminding them of “death” (54% in group 1 and 48% in group 2; p = 0.102). This study suggested that oncology education was useful for the students’ understanding of cancer and related issues; however, the level of oncology education should be improved in medical schools in Turkey. This would be helpful for medical doctors to cope with many aspects of cancer as a major health care problem in this country. © 2018, American Association for Cancer Education.

This study aimed to reveal the habits of using internet by cancer patients and their relatives to access health-related information and services in Turkey.An 18-item questionnaire survey was applied in cancer patients and their relatives.A total of 1106 patients (male, 37.3%, and female, 62.7%) and their relatives were included in the study. The responders had been using internet to obtain health information about oncological diseases, once a month (34.2%), 1-2 times a week (27.4%) or 2-3 times a month (21.9%). After diagnosis of cancer was made, participants more frequently (64.4%) investigated health-related issues, while 64.9% of them considered internet as an important search tool, and 16.7% of them had thought to give up cancer therapy under the influence of internet information. Some (33.1%) participants had used herbal medicine, and 16.7% of them had learnt these herbal products from internet. Still 12.7% of them had not questioned the accuracy of internet information, while 26.9% of them indicated that they had not shared the internet information about cancer with their physicians, and 13 % of them searched information in internet without asking their physicians.Cancer patients and their relatives showed a higher tendency to use health-related internet information which may mislead them, and can result in treatment incompliance. Health professionals should offer evidence-based information to the patients and their relatives through internet.

- Abstract
Objectives: Keratoconjunctivitis sicca (KCS) is characterized by decreased aqueous tear film components, leading to ocular surface damage. Diagnosis involves clinical examination, Schirmer Tear Test (STT1), and Tear Film Break-Up Time (TFBUT) measurement. This retrospective study aimed to assess dry eye syndrome in intact, purebred, Aksaray Malakli breed dogs, and investigate potential associations with hereditary ocular diseases due to inbreeding for phenotype preservation., Animals: Fifty healthy, purebred, intact Aksaray Malakli dogs of varying ages and sexes, all exhibiting conjunctival hyperemia and mucoid ocular discharge. Dogs with chronic diseases, systemic medication, or ongoing ophthalmic treatment were excluded., Procedures: Demographic data, ophthalmic examination results, and ocular anomalies were recorded. STT1 and TFBUT assessments were performed to measure tear production and film stability. STT1 values were scored from 1 (normal) to 4 (severe dry eye), and TFBUT ≥20 s was considered normal. Statistical analyses were used to evaluate correlations and differences., Results: The correlation between age and STT1 values (r = -.182, p = .206) was not statistically significant. Mean STT1 was higher in females than males, though not significantly (p = .849). Dogs without third eyelid gland prolapse had significantly higher STT1 and TFBUT measurements compared to those with prolapse (p = .027). No significant sex difference was found in the frequency of third eyelid prolapse (p = .289). A significant positive correlation was observed between STT1 and TFBUT (r = .924; p < .001)., Conclusions: Aksaray Malakli dogs, particularly those with third eyelid gland prolapse, are predisposed to mild to moderate KCS. These findings suggest the need for further clinical and genetic investigations to better understand and manage dry eye syndrome in this breed., (© 2024 The Author(s).

- Abstract
While some clinics have adopted abbreviated neoadjuvant treatment for HER2-positive breast cancer, there remains a shortage of comprehensive clinical data to support this practice. This is a retrospective, multicenter study. A total of 142 patients were included in the study who are HER2-positive breast cancer, aged ≤ 65 years, with left ventricular ejection fraction ≥ 50%, received neoadjuvant chemotherapy and underwent surgery at 10 different oncology centers in Türkiye between October 2016 and December 2022. The treatment arms were divided into 4-6 cycles of docetaxel/trastuzumab/pertuzumab for arm A, 4 cycles of adriamycin/cyclophosphamide followed by 4 cycles of taxane/TP for arm B. There were 50 patients (35.2%) in arm A and 92 patients (64.8%) in arm B. The median follow-up of all of the patients was 19.9 months (95% CI 17.5-22.3). The 3-year DFS rates for treatment arms A and B were 90.0% and 83.8%, respectively, and the survival outcomes between the groups were similar (p = 0.34). Furthermore, the pathologic complete response rates were similar in both treatment arms, at 50.0% and 51.1%, respectively (p = 0.90). This study supports shortened neoadjuvant treatment of HER2-positive breast cancer, a common practice in some clinics., (© 2024. The Author(s).)

- Abstract
The only phase 3 study on the effectiveness of CDK 4-6 inhibitors in first-line treatment in premenopausal patients with hormone receptor (HR) positive, HER2 negative metastatic breast cancer is the MONALEESA-7 study, and data on the effectiveness of palbociclib is limited. Data are also limited regarding the effectiveness of CDK 4-6 inhibitors in patients whose dose was reduced due to neutropenia, the most common side effect of CDK 4-6 inhibitors. In our study, we aimed to evaluate the effectiveness of palbociclib and ribociclib in first-line treatment in patients with premenopausal metastatic breast cancer and the effect of dose reduction due to neutropenia on progression-free survival. Our study is a multicenter, retrospective study, and factors affecting progression-free survival (PFS) were examined in patients diagnosed with metastatic premenopausal breast cancer from 29 different centers and receiving combination therapy containing palbociclib or ribociclib in the metastatic stage. 319 patients were included in the study. The mPFS for patients treated with palbociclib was 26.83 months, and for those receiving ribociclib, the mPFS was 29.86 months ( p = 0.924). mPFS was 32.00 months in patients who received a reduced dose, and mPFS was 25.96 months in patients who could take the initial dose, and there was no statistical difference ( p = 0.238). Liver metastasis, using a fulvestrant together with a CDK 4-6 inhibitor, ECOG PS 1 was found to be a negative prognostic factor. No new adverse events were observed. In our study, we found PFS over 27 months in patients diagnosed with premenopausal breast cancer with CDK 4-6 inhibitors used in first-line treatment, similar to post-menopausal patients. We did not detect any difference between the effectiveness of the two CDK 4-6 inhibitors, and we showed that there was no decrease in the effectiveness of the CDK 4-6 inhibitor in patients whose dose was reduced due to neutropenia.

- Abstract
Background: Consolidation chemotherapy strategies have demonstrated improved pathological complete response and tumor downstaging rates for patients diagnosed with rectal cancer., Objective: This study aimed to compare perioperative outcomes and pathological complete response rates among different neoadjuvant treatment strategies in patients undergoing total mesorectal excision for locally advanced rectal cancer., Design: Propensity score case-matched study., Setting: High-volume tertiary care centers., Patients: Consecutive patients undergoing curative total mesorectal excision between January 2014 and June 2021 were queried., Interventions: Patients were divided into 3 groups: long-course chemoradiation therapy with (N = 128) or without (N = 164) consolidation chemotherapy or short-course radiotherapy (N = 53) followed by consolidation chemotherapy., Main Outcome Measures: Demographics, preoperative tumor characteristics, histopathologic outcomes, and postoperative complication rates were reviewed and compared. Propensity score match analysis was conducted., Results: A total of 345 patients (mean age: 58 ± 12 years; female: 36%) met the study inclusion criteria. Time interval from neoadjuvant treatment until surgery was longer for patients receiving consolidation chemotherapy ( p < 0.001). Pathological complete response rates were comparable among patients receiving long-course chemoradiation therapy (20.3%) and short-course radiotherapy with consolidation chemotherapy (20.8%) compared to long-course chemoradiation therapy alone (14.6%) ( p = 0.36). After the propensity score case-matched analysis, 48 patients in the long-course chemoradiation therapy with consolidation chemotherapy group were matched to 48 patients in the short-course radiotherapy with consolidation chemotherapy group. Groups were comparable with respect to age, sex, clinical stage, tumor location, type of surgical approach, and technique. Pathological complete response rate was comparable between the groups (20.8% and 18.8%, p = 0.99)., Limitations: Study was limited by its retrospective nature., Conclusions: Among recent neoadjuvant treatment modalities, pathological complete response rates, and short-term clinical outcomes were comparable. Short-course radiotherapy with consolidation chemotherapy is safe and effective as long-course chemoradiation therapy as in a short-term period.

Se revisaron y compararon los datos demográficos, las características preoperatorias del tumor, los resultados histopatológicos y las tasas de complicaciones posoperatorias entre los grupos de estudio. Se realizó un análisis de casos emparejados por puntaje de propensión.RESULTADOS: Un total de 345 pacientes (edad media de 58 ± 12 años y mujeres: 36%) cumplieron los criterios de inclusión del estudio. El intervalo de tiempo desde el tratamiento neoadyuvante hasta la cirugía fue mayor para los pacientes que recibieron quimioterapia de consolidación ( p < 0,001). Las tasas de respuesta patológica completa fueron comparables entre los pacientes que recibieron quimiorradioterapia de larga duración con quimioterapia de consolidación (20,3 %) y radioterapia de corta duración con quimioterapia de consolidación (20,8%) en comparación con la quimiorradiación de larga duración sola (14,6%) ( p = 0,36). Después del análisis de casos emparejados por puntaje de propensión, 48 pacientes en el grupo de quimiorradioterapia de ciclo largo con quimioterapia de consolidación se emparejaron con 48 pacientes en el grupo de radioterapia de ciclo corto con quimioterapia de consolidación. Los grupos fueron comparables con respecto a la edad, sexo, estadio clínico, ubicación del tumor, tipo de abordaje quirúrgico y la técnica. La tasa de respuesta patológica completa fue comparable entre los grupos (20,8% y 18,8%, p = 0,99). La morbilidad postoperatoria a los 30 días y las tasas de fuga anastomótica fueron similares.LIMITACIONES: El estudio estuvo limitado por su naturaleza retrospectiva.CONCLUSIONES: Entre las modalidades de tratamiento neoadyuvante recientes, las tasas de respuesta patológica completa y los resultados clínicos a corto plazo fueron comparables. La radioterapia de corta duración con quimioterapia de consolidación es segura y eficaz como terapia de quimiorradioterapia de larga duración en un período corto.

- Abstract
Surgical patients experience both postoperative pain and anxiety, as they try to cope with pain. Despite technological advances, pharmacological methods are inadequate for decreasing postoperative pain and anxiety. Reflexology has been implemented and considered effective in these areas in many countries. The aim of this study was to determine the effect of reflexology on decreasing postoperative pain and anxiety after a hysterectomy. The study was an intervention randomized study. The population of the investigation is all patients who had a hysterectomy between February 2012 and December 2014 in the Istanbul University Obstetrics and Gynecology service. The sample was 100 women chosen after a power analysis (minimum: 74) (experimental: 54, control: 46) within the population of the investigation who agreed to participate in the study. Using a table of random numbers, patients in the sample were divided into groups. Data was collected using the patient information and vital signs form, State-Trait Anxiety Inventory (STAI-I), Visual Analog Scale (VAS) Pain and Anxiety Scales, and BRIEF pain inventory. All women in the groups had similar sociodemographic, obstetric, and pain characteristics, past experience of illness, and characteristics related to their hysterectomy. All of the patients in the reflexology group stated that reflexology helped them feel better. The reflexology group compared with the control group had lower than the average VAS pain and VAS and STAI anxiety at all assessment times. Reflexology is effective in reducing anxiety and pain., Competing Interests: The authors received a financial support which was supported by the Research Fund of Istanbul University (grant numbers 24201, 2012) and declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
In this study, the authors examined the effects of the "Workplace Health Promotion Program" (WHPP) on pain, fatigue, stress, professional quality of life (Pro-QoL), and coping skills for nurses. The authors conducted a randomized control trial in 30 nurses who agreed to participate in this study. Progressive relaxation training, posture and breath exercises, and ergonomic suggestions as a WHPP were applied to the intervention group ( n = 15) during the five weeks. The intervention group showed decrease in pain ( p = .001), fatigue ( p = .001), and stress levels ( p = .003) and increase in coping skills and Pro-QoL ( p < .05). In contrast, the authors observed no improvement in the control group. The authors concluded at the end of the study that WHPP remains effective in nurses.

- Abstract
Aim: This multi-centered, longitudinal, and prospective study aims to identify women's sexual functions, sexual quality of life, and depression and their relationships with each other in the pregnancy and postpartum periods., Methods: The participating pregnant women (n = 113) were interviewed six times: once in each trimester, and once in the eighth week third month, and sixth month postpartum. This study was conducted in three regions of Turkey including Marmara, Mediterranean, and Central Anatolia regions. Data were collected through the "Socio-demographic Form," "Female Sexual Function Index (FSFI)," Sexual Quality of Life-Female Questionnaire (SQLQ-F), and "Center for Epidemiologic Studies-Depression Scale (CES-D)." While the first interviews were administered face to face, successive ones were administered via phone., Results: The sexual dysfunction rates of the participants were found to be high in the pregnancy and postpartum periods, and their sexual quality of life, which decreased as the pregnancy months progressed, was found to increase significantly with the progress in the postpartum period. The sexual dysfunction increased and sexual quality of life decreased significantly with the increase in depression symptoms in the pregnancy and postpartum periods. When the depressive symptoms decreased especially in the sixth month postpartum, sexual quality of life was also found to increase., Conclusions: As a result, in the pregnancy and postpartum periods, it is highly important to provide women with diagnosis through a holistic approach by creating available environments to assess their psychological health and sexual functions and refer them to the related physicians when necessary., (© 2022 Japan Society of Obstetrics and Gynecology.)
