Understanding changes in pulmonary function and functional status in breast cancer patients after systemic chemotherapy and radiotherapy: a prospective study.

BACKGROUND: Respiratory complications in breast cancer (BC) patients after chemotherapy (CT) and radiotherapy (RT) have been well acquainted and these complications should be investigated to prevent secondary problems and/or improve BC patients' clinical outcomes. Therefore, this study aimed to assess the potential acute effect of systemic chemotherapy and radiotherapy on respiratory function and functional status of patients with breast cancer. METHODS: A total of 25 BC patients who were candidates for systemic chemotherapy and radiotherapy were recruited after oncological examination and included in this study. Respiratory function and functional status were assessed with the Pulmonary Function Test (PFT) and the Six-Minute Walk Test (6MWT), respectively. Patients were assessed before CT (c0), after CT (c1), and after RT (r1). RESULTS: 25 BC patients were assessed in c0 and c1 while only 15 out of 25 patients (60%) were assessed in r1. The actual values of Forced vital capacity (FVC) (t = 2.338, p =.028), Forced expiratory volume in 1s (FEV1 (t = 2.708, p =.012), and the forced expiratory flow of between 25% and 75% of vital capacity (FEF25-75%) (t = 2.200, p =.038) were found significantly different after systemic CT. Inspiratory (MIP) and expiratory (MEP) muscle strength also did not show a significant change from c0 to c1. A significant effect of the type of surgery was found (Wilks' lambda, F [1, 19] = 6.561, p =.019, ηp2 = 0.25) between c0 and c1 in actual FVC value. The main effect of time was found significant in FVC (F [2, 28] = 4.840, p =.016, ηp2 = 0.25) from c0 to r1. Pairwise comparisons with Bonferroni correction showed that there was a significant difference between c0 and r1 (p =.037). DISCUSSION: The present study showed decreased FVC and FEV1 actual values and percent predicted rates from baseline to the completion of treatment. Since the interactional effect of the type of surgery was significant, we suggest that clinical and demographic factors such as age should be considered when interpreting the early changes in PFT. In addition, the significant linear trend of decreasing in some specific outcomes in respiratory function also highlighted the need for continuous monitoring of potential respiratory problems in patients with BC from baseline to the completion of chemotherapy and radiotherapy.

Assessment of sensorimotor and strength related function of breast cancer patients during systemic drug therapy: a prospective observational study.

BACKGROUND: Chemotherapy is a well-known risk factor for sensorial and motor disturbances. Chemotherapy induced peripheral neuropathy (CIPN) which predominantly affects sensory nerves might cause a diminished fine motor function. This prospective observational study aimed to assess the sensorimotor functions of breast cancer patients before, during, and after chemotherapy. METHODS: A total of 56 breast cancer patients were evaluated at three different times as follows: T1 (before chemotherapy), T2 (middle chemotherapy), and T3 (completion of chemotherapy). Motor function was assessed with handgrip strength (HGS), peripheral muscle strength (PMS), and the Minnesota Manual Dexterity Test (MMDT). Semmes Weinstein Monofilament Test (SWMT) was performed to assess the sensory function. Fatigue was evaluated with the European Organization for Research and Treatment of Cancer Quality of Life Module Cancer Related Fatigue (EORTC-QLQ-FA12), respectively. RESULTS: HGS and MMDT were found significant (χ2: 11.279, p = 0.004 and χ2: 9.893, p = 0.007, respectively) whereas PMS was not found significant (F (2,110) = 1.914, p = 0.152). Pairwise comparisons with Bonferroni adjustments revealed that HGS was found significant between T1 and T3, while significant results were obtained between T1 and T2 as well as T2 and T3 in MMDT (p = 0.01 and p = 0.042). There were significant results in some reference points of SWMT, though they were not found after pairwise comparisons with Bonferroni adjustment (p > 0.05). Fatigue was found significantly increased from T1 through T3 (Median: 19.44 vs 27.77, z: -2.347, p = 0.019, Wilcoxon test). CONCLUSION: Our study showed that decreased handgrip strength and fine motor function, as well as increased fatigue, are evident during the chemotherapy. SWMT can be an optional assessment in the context of tracking changes in cutaneous sensation during chemotherapy due to its non-invasive, cheap, and easily repeatable features among cancer patients. To preserve functional capacity as well as independence in daily living, precautions and follow up assessments during the systemic therapy process should be integrated as early as possible to prevent future deteriorations in daily life for patients who undergo chemotherapy.

[The Relationship of Enterotoxigenic Bacteroides fragilis and Fusobacterium nucleatum Intestinal Colonization with Colorectal Cancer: A Case-Control Study Performed with Colon Biopsies]. / Enterotoksijenik Bacteroides fragilis ve Fusobacterium nucleatum Bagirsak Kolonizasyonunun Kolorektal Kanser ile Iliskisi: Kolon Biyopsileri ile Yapilan Bir Olgu Kontrol Çalismasi.

In recent years, it has been shown that some bacteria may be associated with colorectal cancer (CRC). In this study, it was aimed to investigate the role of Fusobacterium nucleatum and enterotoxigenic Bacteroides fragilis (ETBF) in the etiology of CRC by comparing the amounts of these bacteria in colon biopsy tissues of patients with CRC and healthy individuals. The amounts of F.nucleatum and ETBF were determined by quantitative polymerase chain reaction (qPCR) in colon biopsy samples taken from 35 CRC and 35 healthy individuals, and the results were compared in the patient and control groups. The detection rate and amounts of F.nucleatum were found to be statistically significantly higher in tissues of female patients with CRC compared to male patients (p= 0.003, p= 0.013, respectively). There was no statistically significant difference between the tissues of female and male patients with CRC in terms of detection rate and amount of ETBF (p= 0.521, p= 0.515, respectively). It was found that in the 50-74 age group, the amount of ETBF was statistically significantly higher in women and men with CRC compared to the controls (p= 0.005, p= 0.047, respectively), while the amount of F.nucleatum was statistically significantly higher in female patients compared to controls. However, no difference was found between male patients and controls (p= 0.009, p= 0.083). It was determined that the detection rate and amount of F.nucleatum in the tissues of patients with CRC, regardless of age and gender, were not statistically different from the controls (p= 0.473, p= 0.995, respectively), however, the detection rate of ETBF and the amount of ETBF were found to be statistically significantly higher (p= 0.002, p= 0.004, respectively). It has been determined that ETBF can play a role in the etiology of CRC in both men and women, and F.nucleatum only in women, in the age range of 50-74 years, when routine screenings for CRC are performed.

The effect of complex decongestive physiotherapy applied with different compression pressures on skin and subcutaneous tissue thickness in individuals with breast cancer-related lymphedema: a double-blinded randomized comparison trial.

PURPOSE: The aim of this study was to evaluate the effect of compression bandage applied with different pressures on the skin and subcutaneous thickness in individuals with breast cancer-related lymphedema (BCRL). METHODS: 21 individuals with stage 2 unilateral BCRL participated in the study. Individuals were randomly allocated into two groups as low-pressure bandage (20-30 mmHg) (n: 11) and high-pressure bandage (45-55 mmHg) (n: 10). Skin and subcutaneous tissue thickness, extremity volume, sleep quality, treatment benefit, and comfort were evaluated by ultrasound from 6 reference points (as hand dorsum, wrist volar, forearm volar, arm volar, forearm dorsum, and arm dorsum), volumetric measurement, Pittsburgh Sleep Quality Index, Patient Benefit Index-Lymphedema, and visual analog scale, respectively. Complex decongestive physiotherapy was applied to both groups. Compression bandage was applied according to their group. Individuals were evaluated at the baseline, 1st session, 10th session, 20th session, and at 3-month follow-up. RESULTS: Skin thickness decreased significantly in the volar reference points of the extremity in the high-pressure bandage group (p = 0.004, p = 0.031, and p = 0.003). Subcutaneous tissue thickness significantly decreased at all reference points in the high-pressure bandage group (p < 0.05). In the low-pressure bandage group, skin thickness only decreased in the forearm dorsum and the arm dorsum (p = 0.002, p = 0.035) and subcutaneous tissue thickness changed for all points (p < 0.05) except for hand and arm dorsum (p = 0.064, p = 0.236). Edema decreased in a shorter time in the high-pressure bandage group (p < 0.001). No significant differences were found in sleep quality, treatment benefit, and comfort for both groups (p = 0.316, p = 0.300, and p = 0.557, respectively). CONCLUSION: High pressure was more effective in reducing subcutaneous tissue thickness in the dorsum of hand and arm. The usage of high-pressure can be recommended especially in cases which have edema in the dorsum of hand and arm which is difficult to resolve. Also, high-pressure bandage can provide faster edema resolution and can be used in rapid volume reduction as desired. Treatment outcomes may improve with high-pressure bandage without any impairment in comfort, sleep quality, and treatment benefit.

Assessment of the cardiorespiratory fitness and the quality of life of patients with breast cancer undergoing chemotherapy: a prospective study.

BACKGROUND: Diminished cardiorespiratory fitness is a well-known side effect of chemotherapy as well as a risk factor for potential cardiovascular diseases among cancer patients. This study aimed to assess the potential effects of systemic adjuvant (ACT) or neoadjuvant (NACT) chemotherapy on cardiorespiratory fitness and quality of life (QoL) among breast cancer (BC) patients. METHODS: Demographic data, cardiorespiratory fitness, health-related QoL domains were assessed with simple data form, six-minute walk test (6MWT), European Organization for Research and Treatment of Cancer quality of life module (EORTC-C30), and Functional Assessment of Cancer Therapy (FACT-B+), respectively. Time1 (T1, prior to chemotherapy), Time2 (T2; interim assessment), and Time3 (T3, final assessment) were set as assessment points. RESULTS: A total of 42 patients (32 ACT vs 10 ACT) completed all assessments. There were no significant differences of main effect of time and time*group interaction on total walked distance (TWD) after controlling for age and BMI (F(2,28) = 1.309, p = 0.286; F(2,28) = 1.444, p = 0.253). EORTC symptoms subscale was found to be correlated with EORTC and FACT-B+ physical function (PF) subscales (r = - 861, p < 0.001; r = - 0.877, p < 0.001) in T3. The EORTC PF subscale was found to be correlated with the TWD in the baseline (r = 0.411, p = 0.024). CONCLUSIONS: This study showed that the effect of chemotherapy on diminished PF and remarkably increased symptom burden among BC patients. Yet, the type of chemotherapy had no effect on TWD regarding cardiorespiratory fitness. Monitoring potential functional decline regarding cardiorespiratory fitness can be performed via simple field tests such as 6MWT.

The effect of adjuvant radiotherapy on skin biophysical properties in patients with breast cancer at risk for breast lymphedema: A prospective study.

Breast cancer (BC) is the most common type of cancer among women. Radiotherapy (RT) is one of the main and primary treatment options for BC, especially in breast-conserving surgery (BCS). BC patients who underwent RT experience a wide range of symptoms, in which breast oedema and irritation of the skin take the lion's share. Breast oedema/lymphedema, which is also a prominent side effect after RT should be well determined in earlier settings due to the chronicity of lymphedema. Therefore, this study aimed to analyze the biophysical parameters of skin on the ipsilateral (IL) and contralateral (CL) sites via Tissue dielectric constant (TDC) and Transepidermal water loss (TEWL) methods in terms of oedema and skin barrier function (SBF). The following reference points before and after the RT were measured: (R1: Pectoralis muscle, R2: Upper breast, R3: Lower breast, R4: Lateral site of the thorax). A total of 24 BC patients (mean age and BMI: 52.78 ± 9.85 years and 28.42 ± 5.64 kg/m2 ) were evaluated. In the IL site, the SBF was not found significant in R1-R3, whereas significantly lower SBF was observed in R4 after RT (t = -3.361, p = 0.003). A significant increase in TDC was observed in R2 at the 5.0 mm depth (t = -2.500, p = 0.02). We suggest that a longer period of follow-up should be carefully carried out to track changes in terms of SBF and oedema in the irradiated breast. The increased need for early detection of changes associated with breast lymphedema can be achievable via noninvasive, safe, cheap, and easily repeatable devices.

Examination of posture and balance in children with primary monosymptomatic nocturnal enuresis.

PURPOSE: This study aimed to examine symptom severity, posture, and balance of children with primary monosymptomatic nocturnal enuresis (PMNE) and compare to a healthy control group. METHODS: Thirty-five children with PMNE and 34 healthy children were included in this study. Physical and sociodemographic characteristics of the children were recorded. Symptom severity was assessed with a Vancouver Non-Neurogenic Lower Urinary Tract Dysfunction/Dysfunctional Elimination Syndrome Questionnaire (NLUTD/DES), a four-day bladder diary and a seven-day bowel diary. Standing postural alignment was assessed with the Spinal Mouse device, and the sensory integration of static balance and dynamic standing balance was assessed with the Biodex Balance System SD. RESULTS: Compared to healthy controls, children with PMNE demonstrated increased symptom severity (p = 0.001), increased upright lumbar lordosis (p = 0.018) and sacral-hip angles (p = 0.029), decreased static balance in the sensory condition of unstable surface with eyes closed (p = 0.001), and decreased mediolateral dynamic balance (p = 0.049). CONCLUSION: Children with PMNE demonstrate altered postural alignment, static and dynamic postural instability, and greater symptom severity on the Vancouver NLUTD/DES than age-matched controls.

Firmicutes/Bacteroidetes Ratio in the Gut Microbiota and IL-1ß, IL-6, IL-8, TLR2, TLR4, TLR5 Gene Expressions in Type 2 Diabetes.

BACKGROUND: The aim of this study was to determine the Firmicutes/Bacteroidetes ratio in the gut microbiota and IL-1ß, IL-6, IL-8, TLR2, TLR4 and TLR5 gene expression levels in the blood of adult type 2 diabetes (T2D) patients and compare it with that of adult nondiabetic healthy controls (HC). METHODS: Between May 2016 and April 2017, 99 T2D patients and 99 HCs were enrolled in the study. Bacteroidetes and Firmicutes levels were assessed from stool sample DNA and IL-1ß, IL-6, IL-8, TLR2, TLR4, and TLR5 gene expression levels assesed from blood sample RNA via qPCR from both T2D patients and healthy controls. RESULTS: The Firmicutes/Bacteroidetes ratio detected in the stool of type 2 diabetes patients was found to be higher with a statistically significant difference (p < 0.0001). Gene expression levels of IL-1ß, IL-6, IL-8, TLR2, TLR4, and TLR5 were found to be upregulated. CONCLUSIONS: The highest upregulation was detected in IL-6 with 11 fold in T2D patients comparing with HCs. F/B ratio and gene expression levels were elevated in T2D patients. Firmicutes were positively correlated with studied gene expressions. A better understanding of the complex interaction between gut microbiota, environment, and diabetes will allow for more effective prevention and treatment strategies for T2D.

The Characteristics of Pain Tolerance in Patients Who Underwent Unilateral Breast Cancer Surgery: The Effect of Handedness and Surgical Site to Assess the Potential Musculoskeletal Symptoms and Function.

BACKGROUND: Breast cancer survivors (BCS) usually experience musculoskeletal pain and strength imbalance between surgical and nonsurgical sites. MATERIAL AND METHODS: This study aimed to assess the effect of handedness and surgical site on pain tolerance and upper extremity strength in BCS. A total of 96 female BCS (Mean age and BMI: 51.06 ± 9.36 years and 27.77 ± 3.75 kg/m2) were included in this study. BCS were categorized as "DoS" or "NoS" whether they had surgery on their dominant or nondominant site, respectively. Socio-demographic data, upper extremity strength, pain tolerance, and pain-related function measurements were performed by simple form, manual muscle tester, pain algometer, and Disabilities of Arm, Shoulder, and Hand's (DASH) pain subscale, respectively. RESULTS: Pain tolerances were significantly lower in upper trapezius muscle region in the surgical site (t = -4,263, P < .001 and t = -2138, P = 0.037) while in the deltoid tuberosity, pain tolerance was significantly higher in surgical site (t = 2633, P = 0.011). Mean differences in strength in shoulder flexion and abduction were significantly lower in the DoS group compared to the NoS group (z = -3.166, P = .002 and z = -2.131, P = .033, respectively), whereas the pain subscale was significantly higher in the DoS (P = .013). CONCLUSION: Pain tolerance decreased in the upper trapezius muscle region on the surgical site irrespective of the handedness. However, in deltoid tuberosity, the effect of handedness was remarkable. Exercise programs should focus to establish a strength balance in nondominant surgery BCS since strength imbalance might be more prominent to affect them to take part in activities in daily living.

What do lymphedema patients expect from a treatment and what do they achieve? A descriptive study.

PURPOSE: Lymphedema is characterized by swelling and fibroadipose tissue deposition that is a physically, psychologically, and socially debilitating condition due to chronic and progressive nature of the disease. Treatment benefit evaluation from the patient's perspective is important for medical decision-making. The aim of this study is to investigate important treatment goals and benefits of treatment from the patients' perspective. METHOD: Eighty-one patients with lymphedema, lipoedema, or lipolymphoedema who are currenlty treated or who underwent previous treatment were included in the study. Socio-demographic data was recorded. Important goals and benefit from treatment were assessed with Patients Needs Questionnaire and Patient Benefit Questionnaire which are sub-questionnaires of Patient Benefit Index-Lymphedema. RESULTS: The most important expectation and needed item was "To find a clear diagnosis and therapy" (n:59, 72%). The least important item for the lymphedema patients was "To feel more attractive" (n:9, 11%). Most beneficial effect of treatment was "To have no fear that the disease will become worse" (n:37, 45.7%). "To have fewer out of pocket treatment expenses" was rated as the least beneficial effect of treatment (n:24, 29.6%). CONCLUSIONS: It is important to identify patients' needs and expectations. Patients should be referred for treatment according to their needs. The effectiveness of the treatment should be evaluated objectively. Patient education should be considered as a part of the effective treatment to teach patients how to control their lymphedema. A clear diagnosis and access to treatment should be ensured for lymphedema patients. Regulations for health insurance benefit coverage are needed to cover cost of compression garments.

Investigation of the Demodex Lid Infestation with in Vivo Confocal Microscopy versus Light Microscopy in Patients with Seborrheic Blepharitis.

AIM: The comparison of the diagnostic efficiency of a reference method (light microscopy [LM] using 10% potassium hydroxide [KOH]) with the use of 100% alcohol to in vivo confocal microscopy (IVCM) for the detection of Demodex eyelid infestation in seborrheic blepharitis patients. METHODS: Eyelashes were epilated from the right eyes for the reference method and the left eyes for the alcohol group in 58 eyes of 29 patients. IVCM was used on the left eyes. The primary outcomes were the number of Demodex mites per lash and the rate of Demodex positivity (≥1 mite). RESULTS: The rate of Demodex positivity was similar among the three groups (KOH: 82.8%, alcohol: 86.2%, IVCM: 72.4%; p >.05). The mean number of mites per lash in the KOH group (1.5 ± 1.3) was higher than in the alcohol (0.9 ± 0.6, p =.041) and IVCM groups (0.9 ± 0.9, p =.036). CONCLUSION: KOH was found to be superior in terms of the quantification of mites compared to alcohol and IVCM.

Randomized double-blind trial of wipes containing terpinen-4-ol and hyaluronate versus baby shampoo in seborrheic blepharitis patients.

PURPOSE: To investigate the efficacy of lid wipes (LWs) containing terpinen-4-ol and sodium hyaluronate (Hy-ter®) for the treatment of seborrheic blepharitis compared to baby shampoo (BS). METHODS: This randomized, double-blind, active control, parallel group, multicentre clinical trial included 48 eyes of 48 patients with seborrheic blepharitis who were randomly divided into two treatment arms (1:1, n = 24) using block randomization. LWs or BS were prescribed twice a day for 8 weeks followed by a discontinuation period of 4 weeks. Change in Blepharitis Symptom measure (BLISS), Schirmer's test, tear breakup time (TBUT), noninvasive TBUT (NI-TBUT), ocular surface disease index (OSDI) score, corneal and conjunctival staining, meibography, and Demodex count at different visits (Baseline, 4th, 8th, and 12th week) were the main outcome measures. RESULTS: The baseline values of both groups were similar (p > 0.05). Despite high clinical efficacy in both treatment arms, patients using LWs showed a lower BLISS score at the 8th and 12th-week visit (1.9 ± 2.2 versus 7.2 ± 6.6, p = 0.003; 4.0 ± 1.3 versus 5.8 ± 6.3, p = 0.026). NI-TBUT showed a significant increase starting from the 4th week for patients using LWs and 8th week for patients using BS. Both treatment modalities caused a reduction in the Demodex count after 4 weeks of treatment (p < 0.001). The treatment withdrawal did not cause any recurrence in both treatment arms. CONCLUSION: BS or LWs containing Hy-ter® can be used with good efficacy for the treatment of seborrheic blepharitis. However, LWs may provide a better symptomatic relief compared to BS after 8 weeks of treatment.

PLANTAR SENSATION AND BALANCE IN PATIENTS WITH TYPE 2 DIABETES MELLITUS WITH AND WITHOUT PERIPHERAL NEUROPATHY.

The aim of the study was to investigate the effect of diabetes on plantar sense and balance in patients with type 2 diabetes mellitus (T2DM). The study included 300 subjects divided into three groups: 100 T2DM patients with diabetic peripheral neuropathy (group 1); 100 T2DM patients without peripheral neuropathy (group 2); and 100 subjects without DM (group 3). Berg Balance Scale (BBS), Timed Up and Go test (TUG), single leg test with eyes open and closed, and plantar sensory tests were applied in the subjects. Study results showed significant differences in plantar sensory tests, BBS, TUG and single leg test among the three groups (p<0.05). In addition, duration of DM and medication were negatively correlated with single leg test both with eyes open and closed, but showed positive correlation with plantar sense and TUG test. Furthermore, the length of insulin therapy showed positive correlation with plantar sense and TUG test and negative correlation with BBS (p<0.05). In conclusion, DM has an effect on plantar sense and balance, and there is a relation between the duration of DM and balance problems. Balance problems are observed more often in patients with neuropathy.

Swabs Containing Tea Tree Oil and Chamomile Oil Versus Baby Shampoo in Patients With Seborrheic Blepharitis: A Double-Blind Randomized Clinical Trial.

PURPOSE: The comparison of the efficacy of swabs containing tea tree oil and chamomile oil and baby shampoo (BS) in the treatment of seborrheic blepharitis was aimed. METHODS: This randomized, double-blind, parallel-group, active control, multicenter clinical trial included patients with seborrheic blepharitis using block randomization (BS, n=23; swabs, n=26). Patients were treated with BS or swabs for 8 weeks followed by 4 weeks of treatment withdrawal. Change in Blepharitis Symptom measure (BLISS), Demodex count, Ocular Surface Disease Index (OSDI) score, Schirmer test, tear breakup time (TBUT), noninvasive TBUT (NI-TBUT), corneal staining, and meibography at different visits (baseline, fourth, , and 12th week) were the main outcome measures. RESULTS: Patients in both groups showed similar baseline parameters (P>0.05). Patients using swabs showed significantly lower BLISS scores compared with patients using BS at the 4th, 8th, and 12th week visits (3.6±6.1 vs. 6.3±4.5 P=0.011; 1.1±2.8 vs. 6.6±6.7, P<0.001; 0.9±2.8 vs. 5.7±6.6, P=0.002, respectively). Patients using swabs showed improvement in OSDI scores after 8 weeks of treatment compared with the baseline visit (P<0.001). Despite a similar Demodex reduction effect in both treatment arms even after 4 weeks of treatment (P<0.001), both treatment modalities did not show any effect on the other parameters. CONCLUSION: Although both swabs and BS showed efficacy for the treatment of seborrheic blepharitis in terms of the Demodex reduction and symptomatic improvement, swabs may provide better symptomatic improvement. Four weeks of treatment discontinuation may not cause any recurrence in the symptoms or Demodex infestation.

An Important Tool in Lymphedema Management: Validation of Turkish Version of the Patient Benefit Index-Lymphedema.

Background: The aim of this study was to investigate the Turkish adaptation, validity, and reliability of the Patient Benefit Index-Lymphedema (PBI-L) ensuring direct assessment of the benefit in patients with lymphedema (LE), lipedema, and lipolymphedema. Methods and Results: Eighty-one patients who were consulted for physiotherapy, whose diagnoses were LE, lipedema, and lipolymphedema, and who were treated or planned to be treated for these diagnoses, were included in this study. PBI-L was adapted to Turkish by considering the stages of the cultural adaptation process. Short Form-36 (SF-36) was applied for the validity of PBI-L. PBI-L was repeated after a 1-week interval for test-retest reliability. The mean age was 47.66 ± 14.23 years. The intraclass correlation coefficient (ICC) value was determined as 0.73 (p < 0.0001) for the total score. There was a moderate correlation between first (ICC = 0.63, p < 0.0001) and second subdimensions (ICC = 0.62, p < 0.0001). Cronbach's α values ranged between 0.83 and 0.89. Low correlations were found between total scores of PBI-L and mental health, physical function subdimensions of SF-36 (p < 0.05). The Kaiser Meyer Olkin value was 0.6, and it was found that the PBI-L was not consistent with factor analysis. Conclusion: The Turkish version of PBI-L is a valid and reliable tool in patients with LE, lipedema, and lipolymphedema. However, the reassessment validity of PBI-L would be suggested by using an LE-specific quality of life questionnaire.

Comparison of a 12-Week Whole-Body Exergaming Program on Young Adults: Differentiation in Flexibility, Muscle Strength, Reaction Time, and Walking Speed Between Sexes.

This study aimed to investigate the effects of exergaming on flexibility, muscle strength, reaction time, and walking speed of adults within sex differences. Fifty-four individuals participated in a 12-week exergaming program. Three 30-min sessions were conducted each week. Baseline and post-intervention assessments were done using the sit-and-reach and bend-over tests for flexibility, hand-held dynamometer for muscle strength, auditory and visual reaction time machine for reaction time, and 5-meter walk test for walking speed. There were no significant changes in the sit-and-reach, bend-over test, and auditory-visual reaction time for either gender (p > .05) with the intervention. Walking speed and muscle strength improved after exergaming in both sexes (p < .05). The study showed that the video gaming intervention led to significant and equal improvements in muscle strength and walking speed for both sexes; however, it had no impact on flexibility and auditory-visual reaction time.

Bacteroidetes and Firmicutes levels in gut microbiota and effects of hosts TLR2/TLR4 gene expression levels in adult type 1 diabetes patients in Istanbul, Turkey.

AIM: The aim of this study was to determine and compare the levels of both Bacteroidetes and Firmicutes in the gut microbiota and TLR2/TLR4 gene expression in the blood of patients with type 1 diabetes mellitus (T1DM) and healthy individuals. These results may serve as a preliminary assessment to guide future research. METHOD: Between January and October 2014, stool and blood samples were collected from 53 adult T1DM patients and 53 age- and gender-matched healthy individuals. Bacteroidetes and Firmicutes levels were assessed from stool sample DNA and TLR2 and TLR4 expression levels were analyzed via qPCR using RNA from EDTA blood samples from both patients and healthy controls. RESULTS: The amounts of Bacteroidetes and Firmicutes were statistically significantly higher and lower, respectively, in the T1DM group than in the healthy control group (p < 0.001 and p < 0.001, respectively). In addition, the Firmicutes/Bacteroidetes ratios in patients with T1DM were significantly lower than in healthy controls. The TLR4 and TLR2 gene expression levels in T1DM patients were significantly upregulated and downregulated, respectively, compared to those in the control group. CONCLUSION: Our data are the first to show a relationship between T1DM and gut microbiota in our country. In addition, our results provide information about the connections between T1DM, gut microbiota, and TLR2 and TLR4 expression. We believe that Bacteroidetes and Firmicutes in the gut microbiota may play a role in the autoimmune process of T1DM and that these findings should be further investigated in the future.

Translation, reliability, and validation of the Turkish version of the Lymphedema Quality-of-Life tool in Turkish-speaking patients with lower limb Lymphedema.

The aim of this study was to translate the original English version of the Lymph Quality-of-Life Questionnaire (LYMQoL) into Turkish language and test its reliability and validity in patients with lower limb lymphedema (LLL). A total of 119 patients (86 women and 33 men) with LLL were enrolled in this study. The Turkish version of the Nottingham Health Profile was used to evaluate the criterion validity of related domains in LYMQoL. The LYMQoL was performed after seven days to evaluate its test-retest reliability. Cronbach's alpha value was found to be 0.94 for internal consistency, and the intraclass correlation coefficient score for test-retest reliability was found to be 0.95. The intraclass correlation coefficient score of domains ranged between 0.83 and 0.92. For the criterion validity, "functional aspects" and "symptoms" domains moderately correlated significantly with the Nottingham Health Profile total score. Kappa values ranged from 0.356 to 0.715. According to the factor analysis, four factors that explain the 71% of the cumulative variance were found. In conclusion, this study indicates that the Turkish version of the LYMQoL is a reliable valid tool for the evaluation of disease-specific health-related quality of life in patients with LLL. It can be safely used in both clinical routine and research.

Tissue dielectric constant and circumference measurement in the follow-up of treatment-related changes in lower-limb lymphedema.

BACKGROUND: Lymphedema of lower limbs is a chronic condition that requires life-long management. Therapeutic effect of complex decongestive physiotherapy (CDP) is most often followed by circumference measurements (CM). However, the CM measurements are not specific to interstitial tissue fluid and have problems in sensitivity and objectivity. The aim of present study was to evaluate the therapeutic effect of CDP with a new tissue water specific measurement technique, in patients with lower limb lymphedema (LLL). METHODS: A total of 17 patients with unilateral LLL (11 primary, 6 secondary lymphedema) were recruited in this study. CDP was applied for 5 days a week for 4 weeks. CM measurement of both limbs was performed at nine sites along limb by tape measure. Percentage skin water content (PWC) of thigh, calf and ankle was measured in affected lymphedema limb and contralateral limb with MoistureMeterD Compact (MMDC) device. Inter-limb PWC ratio was calculated by dividing affected side's PWC value with PWC of contralateral limb. Patients were asked to fullfill the Lymph Quality of Life Questionnaire. RESULTS: Significant reduction of circumference after CDP was detected at all nine measurement sites along lower limb (P<0.01). PWC measurements showed a significant decrease of skin tissue water at thigh, calf and ankle measurement sites after CDP (P<0.001). Inter-limb PWC ratios demonstrated significant reduction of edema between affected and contraletral limbs post-treatment (P<0.003). CDP also increased the quality of life (P=0.006). CONCLUSIONS: CM and PWC measurements reflected a positive effect of CDP in patients with LLL. Both absolute PWC values and inter-limb PWC ratios were meaningful tools to follow the effect of therapautic intervention. Compared with CM measurements the TDC technique offered easier, quicker, objective and more practical measurements for routine assessments of LLL.

Measurement of Local Tissue Water in Patients with Breast Cancer-Related Lymphedema.

BACKGROUND: Studies revealed that having "1.20" or upper interarm local tissue water (LTW) ratio which can be calculated through tissue dielectric constant (TDC) method might be the determinant of clinical lymphedema after breast cancer surgery. The purpose of this study was to confirm these findings and determine the sensitivity and specificity of LTW (%) measurement method in patients with breast cancer related lymphedema (BCRL). METHODS AND RESULTS: Sixty-three participants were recruited to this study in two groups as follows: the lymphedema group (n = 32), who had BCRL after breast cancer surgery, and the latent group (n = 31), who had breast cancer surgery yet having no lymphedema. LTW (%) measurement of those was conducted with Moisture Meter-D compact (MMDc, Delfin Technologies, Kuopio, Finland) at sites 8 cm proximal (biceps) and 6 cm distal (forearm) from the antecubital fossa, 10 cm inferior from the axilla (lateral thorax) in 2.5 mm depth. Sensitivity and specificity of TDC method were analyzed based on the reference having 1.20 or upper interarm LTW ratio in both groups. RESULTS: Absolute LTW (%) values were significantly different (p < 0.001) between groups in forearm (latent: 26.96 ± 3.35, lymphedema: 36.85 ± 9.32) and in biceps (latent: 26.54 ± 4.11, lymphedema: 36.45 ± 9.91) while in lateral thorax reference point (latent: 35.22 ± 7.44, lymphedema: 33.32 ± 5.08) there was not (p = 0.241). Interarm LTW ratios were significantly different (p < 0.001) between groups in forearm (latent: 1.01 ± 0.06, lymphedema: 1.40 ± 0.35) and in biceps (latent: 1.02 ± 0.10, lymphedema: 1.42 ± 0.38) while in lateral thorax reference point (latent: 1.10 ± 0.25, lymphedema: 1.07 ± 0.16) there was not (p = 0.896). Sensitivity and specificity of the TDC method were 65% and 94%, respectively. CONCLUSION: Absolute LTW (%) values and interarm LTW ratios were significantly different between patients with clinically diagnosed BCRL and patients with no BCRL (latent group). TDC method has been gradually gaining attention in clinical use and this method might be the preferable method in case of early detection of BCRL in patients in latent phase. Regular follow-ups would be beneficial if objective and sensitive measurement techniques were done in clinical settings.
