Efficacy of a Proprietary Trigonella foenum-graecum L. De-Husked Seed Extract in Reducing Menopausal Symptoms in Otherwise Healthy Women: A Double-Blind, Randomized, Placebo-Controlled Study.

Trigonella foenum-graecum seed extract has demonstrated hormone modulatory activity, providing biological plausibility for relieving menopausal symptoms. The study aimed to assess efficacy of a standardized T. foenum-graecum de-husked seed extract in reducing menopausal symptoms in healthy aging women. The study was a double-blind, randomized, placebo-controlled trial that recruited 115 women aged 40 to 65 years of which 59 were allocated to active (n = 54 completed) and 56 to placebo (n = 50 completed). Active treatment was T. foenum-graecum de-husked seed extract, 600 mg per day for 12 weeks. Outcome measures included Menopause-Specific Quality of Life (MENQOL) questionnaire, frequency of hot flushes and night sweats and serum estradiol levels. There was a significant reduction in menopausal symptoms in the active group compared with placebo as assessed by total MENQOL score (p < 0.001); reflected by significant improvements in the vasomotor (p < 0.001), psychosocial (p < 0.001), physical (p < 0.001) and sexual symptoms (p < 0.001) domains. Vasomotor outcomes correlated with hot flushes, the active group reporting significantly less daytime hot flushes and night sweats at 12 weeks (p < 0.001). The average estradiol levels were similar in both the active group and placebo group after treatment. This study demonstrated that this proprietary T. foenum-graecum de-husked seed extract may reduce menopausal symptoms in healthy women. Copyright © 2017 John Wiley & Sons, Ltd.

Treatment with 4Jointz reduces knee pain over 12 weeks of treatment in patients with clinical knee osteoarthritis: a randomised controlled trial.

OBJECTIVE: To assess the efficacy of thrice daily topical 4Jointz utilizing Acteev technology (a combination of a standardized comfrey extract and a pharmaceutical grade tannic acid, 3.5 g/day) on osteoarthritic knee pain, markers of inflammation and cartilage breakdown over 12 weeks. PATIENTS AND METHODS: Adults aged 50-80 years (n = 133) with clinical knee OA were randomised to receive 4Jointz or placebo in addition to existing medications. Pain and function were measured using a visual analogue scale (VAS) and the Knee Injury and Osteoarthritis Outcome Score (KOOS) scale at baseline, 4, 8 and 12 weeks. Inflammation was measured analysing IL-6 expression and CTX-2 presence as representative for cartilage breakdown using ELISA, at baseline and 12 weeks. RESULTS: Pain scores significantly reduced in the group who received 4Jointz compared to the group who received placebo after 12 weeks using both the VAS (-9.9 mm, P = 0.034) and the KOOS pain scale (+5.7, P = 0.047). Changes in IL-6 and CTX-2 were not significant (-0.04, P = 0.5; -0.01, P = 0.68). Post-hoc analyses suggested that treatment may be most effective in women (VAS -16.8 mm, P = 0.008) and those with milder radiographic osteoarthritis (OA) (VAS -16.1 mm, P = 0.009). Rates of adverse events were similar in both groups, excepting local rash that was more common amongst participants receiving 4Jointz (21% vs 1.6%, IRR 13.2, P = 0.013), but only 26% (n = 4) of participants with rashes discontinued treatment. There were no changes in systemic blood results. CONCLUSIONS: Topical treatment using 4Jointz reduced pain but had no effect on inflammation or cartilage breakdown over 12 weeks of treatment.

Effects of a gliadin-combined plant superoxide dismutase extract on self-perceived fatigue in women aged 50-65 years.

Fatigue syndromes exist on a continuum of severity from mild and transient to the disabling chronic fatigue syndrome, with oxidative stress linked to its pathogenesis. A thermolabile gliadin-combined plant superoxide dismutase (SOD) extract has shown potential in clinical trials as a therapeutic antioxidant. This study investigated the effects of 12 weeks of 500 mg/day of a SOD/gliadin supplement on fatigue. Thirty-eight women aged 50-65 years with self-perceived fatigue entered this randomized, double-blind, placebo-controlled trial. The primary outcome measure was general fatigue determined by the Multidimensional Fatigue Inventory (MFI). Secondary outcome measures included other measures of fatigue from the MFI and blood measures of oxidative stress, antioxidant status and hormones. There were no significant (P>0.05) differences between, or within groups, for decreases in general fatigue (active=1.6%, placebo=4.1%). There were no within or between group differences (P>0.05) in other measures of fatigue (physical fatigue, reduced activity, reduced motivation, mental fatigue and total fatigue score). In regard to the biochemical measures, there were non-significant (P>0.05) differences in increases in plasma SOD activity (active=7.1%, placebo=12.2%), plasma GPx activity (active=2.4%, placebo=0.7%), red blood cell GPx activity (active=9.8%, placebo=4.4%). Markers of oxidative stress were decreased but there were no differences (P>0.05) within or between groups; malondialdehyde (active=4.1%, placebo=1.6%), F-2 isoprostanes (active=14.7%, placebo=22.4%). There was a trend (P=0.08) for a decrease in cortisol in the active group (24.6%), however this was not significantly different from the decrease in the placebo participants (4.1%). DHEA differences were not significant (P<0.05) and declined 1.3% in the active group and 14.4% in the placebo group. In summary, the thermolabile SOD/gliadin supplement had no significant effect on self-perceived fatigue, antioxidants, oxidative stress or hormones in women aged 50-65 years.

Fluorescence diagnosis of face-located basal cell carcinomas: a new dermatological procedure which may help the surgeon.

Cutaneous Fluorescence Diagnosis (FD) is a new promising dermatological procedure which is based on the combination of a local application of a photosensitizer such as 5-aminolevulinic acid (ALA) or its methyl ester (MAL) and the use of a light source (red light) adapted to the absorption spectrum of these molecules. The targeted photosensitization of skin cancers, particularily superficial and extensive lesions including superficial basal cell carcinoma and Bowen's disease, by ALA or MAL induced porphyrins leads to a selective red fluorescence which can be demonstrated by Wood's lamp. This technique may be useful either to define better the choice of margins or to detect earlier and or multifocal recurrences.

Imported melioidosis with an isolated cutaneous presentation in a 90-year-old traveller from Bangladesh.

Melioidosis is a tropical disease caused by infection with the bacterium Burkholderia pseudomallei. Most cases present as an acute febrile illness with severe pneumonia and sepsis. Sub-acute and late onset disease can also occur Melioidosis has been diagnosed among travellers who contracted the disease while staying in endemic areas during the rainy season. We report a case of travel-associated B. pseudomallei cutaneous infection in a febrile 90-year-old woman with diabetes mellitus, with early stage manifestations of an isolated inoculation lesion. A 32 weeks' treatment with oral amoxicillin-clavulanate and doxycycline combination regimen led to resolution of the lesion and lack of relapse over fifteen months of follow-up. Melioidosis should be considered in the differential diagnosis of unusual subacute cutaneous lesions in a febrile patients returning from endemic areas, as successful management largely depends on early diagnosis and specific long-term suppressive antimicrobial therapy at an early stage of the course of the disease.

[Cutaneous side effects of a long-term treatment by hydroxyurea]. / Complications cutanées du traitement au long cours par l'hydroxyurée.

Hydroxyurea is an antitumour agent used most commonly to treat myeloproliferative disorders. We present a clinical observation illustrating different cutaneous side effects susceptible to occur during a long-term treatment by hydroxyurea : leg ulceration, oral ulcer and spinocellular carcinoma. This clinical observation is completed by a review of the literature published on the cutaneous side effects of hydroxyurea treatment.

Evaluation of extensive initial staging procedure in intermediate/high-risk melanoma patients.

INTRODUCTION: Early diagnosis and treatment of metastases have been shown to improve overall survival of melanoma patients. The purpose of this study was to evaluate the impact of extensive initial staging, including positron emission tomography (PET) scan on the management of melanoma patients. PATIENTS AND METHODS: Forty-three patients with intermediate/poor prognosis primary melanoma benefited from complementary excision and sentinel lymph node biopsy (SLB) after clinical and paraclinical staging (computed tomography, nuclear magnetic resonance and whole body fluorodeoxyglucose PET scan). RESULTS: No systemic metastases were demonstrated, while the SLB procedure emphasized the presence of regional lymph node metastases in 10 patients as suggested by the PET scan in four patients (sensitivity of the PET scan 40%). These 10 patients with early diagnosed lymph node involvement benefited from early surgery and were included in adjuvant treatment protocols. A secondary primary cancer was fortuitously diagnosed and treated early in two patients. CONCLUSIONS: The development of new adjuvant therapies and therapeutic procedures (specific and non-specific immunotherapy, gamma-knife radiosurgery, etc.) now raises the relevance of extensive staging in intermediate/poor prognosis melanoma patients. We confirm in our series that PET scan is not useful to detect micrometastasis and cannot replace SLB in initial regional staging. However, we show in our study that 12 of 43 patients were treated early or were included early in treatment protocols thanks to the extensive staging procedure. Nevertheless, it seems important to evaluate through larger prospective trials the real impact of these early diagnoses and new treatments on overall survival before defining new diagnostic and therapeutic guidelines.

[Graft-versus-host disease: Review of 22 cases]. / Maladie du greffon contre l'hôte: revue de 22 cas.

PURPOSE: Graft-versus-host disease (GVHD) is one of the major complications of allogeneic bone marrow transplantation. Twenty-two patients, who had an allogeneic bone marrow transplantion at the Institute J. Bordet, developed a GVHD proven by a biopsy. RESULTS: Twenty-two cases of GVHD were registered; 17 of these patients suffered from the acute form of the disease. All the patients presented the characteristic skin lesions, usually associated with other organ involvement. Most of the cases suffered from relapse after a time-limited response or from resistance to therapy, despite an effective treatment. Uncontrolled GVHD led to the death of two patients. CONCLUSION: GVHD is a frequent pathology that significantly contributes to the morbidity and mortality associated with bone marrow transplantation, despite appropriate management. Recognition of clinical and histopathological features of GVHD is important for dermatologists involved in the care of bone marrow transplant patients. Actually, bone marrow transplantation is now easily and more frequently performed than in the past.

Role of Bcl-2 as a prognostic factor for survival in lung cancer: a systematic review of the literature with meta-analysis.

The role of the anti-apoptotic protein Bcl-2 in lung cancer remains controversial. In order to clarify its impact on survival in small and non-small cell lung cancer (NSCLC), we performed a systematic review of the literature. Trials were selected for further analysis if they provided an independent assessment of Bcl-2 in lung cancer and reported analysis of survival data according to Bcl-2 status. To make it possible to aggregate survival results of the published studies, their methodology was assessed using a quality scale designed by the European Lung Cancer Working Party (including study design, laboratory methods and analysis). Of 28 studies, 11 identified Bcl-2 expression as a favourable prognostic factor and three linked it with poor prognosis; 14 trials were not significant. No differences in scoring measurement were detected between the studies, except that significantly higher scores were found in the trials with the largest sample sizes. Assessments of methodology and of laboratory technique were made independently of the conclusion of the trials. A total of 25 trials, comprising 3370 patients, provided sufficient information for the meta-analysis. The studies were categorised according to histology, disease stage and laboratory technique. The combined hazard ratio (HR) suggested that a positive Bcl-2 status has a favourable impact on survival: 0.70 (95% confidence interval 0.57-0.86) in seven studies on stages I-II NSCLC; 0.50 (0.39-0.65) in eight studies on surgically resected NSCLC; 0.91 (0.76-1.10) in six studies on any stage NSCLC; 0.57 (0.41-0.78) in five studies on squamous cell cancer; 0.75 (0.61-0.93) and 0.71 (0.61-0.83) respectively for five studies detecting Bcl-2 by immunohistochemistry with Ab clone 100 and for 13 studies assessing Bcl-2 with Ab clone 124; 0.92 (0.73-1.16) for four studies on small cell lung cancer; 1.26 (0.58-2.72) for three studies on neuroendocrine tumours. In NSCLC, Bcl-2 expression was associated with a better prognosis. The data on Bcl-2 expression in small cell lung cancer were insufficient to assess its prognostic value.

[VEGF and survival of patients with lung cancer: a systematic literature review and meta-analysis]. / VEGF et survie des patients atteints d'un cancer pulmonaire. Revue systématique avec méta-analyse.

The process of angiogenesis is an important factor in tumour development. One of the principal factors implicated in this process is vascular endothelial growth factor (VEGF) which induces, among other things, an increase in vascular permeability. We have undertaken a systematic review of the English and French literature in order to clarify its effect on the survival of patients with small cell (SCLC) and non-small cell (NSCLC) lung cancer. To be eligible studies had to deal with the the evaluation of VEGF or its receptors in lung cancer and describe the relationship of their expression to survival. The survival figures were subject to meta-analysis after a methodological evaluation by means of a specific numerical scale evaluating the design of the study, the methodology (including laboratory techniques), and the analysis of results. Among the 20 studies selected 15 identified VEGF expression, using univariate analysis, as a statistically significant indicator of poor prognosis. 17 reported sufficient data to allow aggregation of the survival figures, of which 15 were devoted to NSCLC (1,549 patients). The median overall methodological score was 48.3% (range 21.8-72.4%), without significant difference (p=0.63) between studies eligible or non-eligible for meta-analysis. The meta-analysis, using the authors' threshold of positivity for VEGF, showed that VEGF is an unfavourable prognostic factor in NSCLC (HR=1.48; 95% confidence interval 1.27-1.72). The data were insufficient to determine the prognostic value of VEGF in SCLC and that of its two receptors Flt-1 and KDR, with 1, 2 and 1 published studies respectively. In conclusion the expression of VEGF in MSCLC is a factor indicating a poor prognosis.

The role of EGF-R expression on patient survival in lung cancer: a systematic review with meta-analysis.

The prognostic value of epidermal growth factor receptor (EGF-R) for survival of patients with lung cancer remains controversial. The authors performed a systematic review of the literature in order to clarify its impact. Published studies were identified using an electronic search in order to aggregate the available survival results, after a methodological assessment using a scale specifically designed by the European Lung Cancer Working Party (ELCWP). To be eligible, a study had to have dealt with EGF-R assessment in lung cancer patients on the primary site and to have analysed survival according to EGF-R expression. Among the 16 eligible studies, 14 assessed any nonsmall-cell lung cancer (NSCLC) subtype, one adenocarcinoma only and one squamous-cell carcinoma only. The overall median quality score was 56.3%, with no significant difference either between studies assessable or not assessable for meta-analysis or between studies with significant and nonsignificant results. One individual trial reported a survival benefit for patients with EGF-R expression, three a survival disadvantage and 12 no statistically significant difference. Eleven studies (2,185 patients) provided sufficient data to allow a meta-analysis of the survival results. EGF-R expression positivity was determined according to the cut-off as determined by the authors. The meta-analysis showed that EGF-R expression was not a statistically significant prognostic factor for survival in NSCLC. In the subgroup of studies using immunohistochemistry, statistical tests reached a significant level against EGF-R. Epidermal growth factor receptor might be a poor prognostic factor for survival in nonsmall-cell lung cancer. The amplitude of the impact is small, however, and may be subject to publication bias.

Therapeutic use of granulocyte and granulocyte-macrophage colony-stimulating factors in febrile neutropenic cancer patients. A systematic review of the literature with meta-analysis.

The effectiveness of granulocyte and granulocyte-macrophage colony-stimulating factor (G-CSF and GM-CSF) in the treatment of febrile neutropenic cancer patients remains controversial. To assess their role in this condition, we conducted a systematic review of randomised trials published as full papers. A methodological evaluation using a specifically designed quality scale was performed before meta-analysis. Eleven trials were eligible, 8 of which were meta-analysable. The median quality score for the 11 pooled trials was 58.3% (range: 33.3%-68.8%). No significant quality difference was observed between positive (colony-stimulating factor more effective) and negative trials ( P=0.36). No quality difference was observed between the 8 meta-analysable studies and the 3 others, with respective median scores of 59.3% and 50%. No advantage was detected for the use of CSF in terms of mortality from febrile neutropenia, with a relative risk of 0.71 (95% CI 0.44-1.15). The relative risk was 0.66 (95% CI 0.39-1.13) in the G-CSF subgroup and 0.97 (95% CI 0.34-2.79) in the GM-CSF subgroup. Aggregation of the results on infection-related mortality, length of stay in hospital, fever and of neutropenia duration, antibiotic therapy adaptation and duration, superinfection rate and toxicity was not possible owing to the lack of adequate data in the publications. On the basis of this review, we cannot recommend the routine use of G-CSF or GM-CSF in established febrile neutropenia.

Role of p53 as a prognostic factor for survival in lung cancer: a systematic review of the literature with a meta-analysis.

The role of p53, as a prognostic factor for survival in lung cancer, is controversial and the purpose of the present systematic review of the literature is to determine this effect. Published studies were identified with the objective to aggregate the available survival results after a methodological assessment using a scale specifically designed by the European Lung Cancer Working Party (ELCWP). To be eligible, a study had to deal with p53 assessment in lung cancer (primary site) only, and to provide a survival comparison according to the p53 status. Among the 74 eligible papers, 30 identified p53 abnormalities as a univariate statistically significant poor prognostic factor and 56 provided sufficient data to allow survival results aggregation. There was no significant difference between the trials that either showed or did not show a prognostic effect of p53 according to the methodological score or to the laboratory technique used. The studies were categorized by histology, disease stage, treatment and laboratory technique. Combined hazard ratios suggested that an abnormal p53 status had an unfavourable impact on survival: in any stage nonsmall cell lung cancer (NSCLC) the mean (95% confidence interval) was 1.44 (1.20-1.72) (number of studies included in the subgroup was 11), 1.50 (1.32-1.70) in stages I-II NSCLC (n=19), 1.68 (1.23-2.29) in stages I-IIIB NSCLC (n=5), 1.68 (1.30-2.18) in stages III-IV NSCLC (n=9), 1.48 (1.29-1.70) in surgically resected NSCLC (n=20), 1.37 (1.02-1.85) in squamous cell carcinoma (n=9), 2.24 (1.70-2.95) in adenocarcinoma (n=9), 1.57 (1.28-1.91) for a positive immunohistochemistry with antibody 1801 (n=8), 1.25 (1.09-1.43) for a positive immunohistochemistry with antibody DO-7 (n=16), and 1.65 (1.35-2.00) for an abnormal molecular biology test (n=13). Data were insufficient to determine the prognostic value of p53 in small cell lung cancer. In each subgroup of nonsmall cell lung cancer, p53 abnormal status was shown to be associated with a poorer survival prognosis.

The role of mitomycin in the treatment of non-small cell lung cancer: a systematic review with meta-analysis of the literature.

In order to clarify the role of mitomycin (MMC) in the treatment of NSCLC, we performed a systematic review of the literature and qualitatively assessed the selected studies using the ELCWP and Chalmers scales. 5 trials (202 patients) assessed the activity of MMC as single-agent chemotherapy in NSCLC. The overall response rate was 25% (95% Cl 19-31). In 10 randomized phase III trials (1769 patients), we studied the role of MMC in combination therapy. A meta-analysis, based on the available published data, failed to show any survival advantage of the MMC containing regimens (hazard ratio = 0.95; 95% Cl 0.83-1.10). Finally, 4 eligible trials (139 patients) assessed the activity of MMC regimens as salvage therapy, 3 in combination with vindesine and one with cisplatin and vinblastine. The overall response rate for the MMC-vindesine regimen was 10.5% (95% Cl 1.7-19.4). In conclusion, MMC is an active drug for NSCLC but does not improve survival when combined with other active drugs, particularly cisplatin. Its use for salvage therapy appears to be associated with marginal activity only.

[The role of chemotherapy in the treatment of non-metastatic, non-small cell bronchial cancers]. / La place de la chimiothérapie dans le traitement des cancers bronchiques non à petites cellules, non métastatiques.

A systematic review of the literature about the role of chemotherapy in comparison to local therapies--surgery or radiotherapy--in non-small cells lung cancers has identified 35 randomised trials. The methodological assessment has not shown significant difference for quality scores between negative or positive studies in term of survival effect. The aggregation (meta-analysis) shows a significant effect of survival improvement by chemotherapy, whatever all indications are considered or subgroups like adjuvant chemotherapy to surgery, neoadjuvant chemotherapy, concomitant radio-chemotherapy and induction chemotherapy prior to thoracic irradiation.

Stress tolerance and membrane lipid unsaturation in Saccharomyces cerevisiae grown aerobically or anaerobically.

Saccharomyces cerevisiae cells grown either aerobically or anaerobically were tested for tolerance to a brief heat stress (52 degrees C, 5 min) or oxidative stress (20 mM H2O2, 15 min). Tolerance was related to growth phase, in that stationary phase cells were intrinsically more resistant to heat or oxidative stress than exponential phase cells. A mild heat shock (37 degrees C, 30 min) induced thermotolerance and oxidative tolerance in both aerobic and anaerobic cells. However, prior exposure to a low concentration of H2O2 (0.1 mM, 60 min) induced protection against the lethal concentration of H2O2 but not against the lethal temperature. Sensitivity to both heat and oxidative stress was dependent on membrane lipid composition. In the case of anaerobic cells, the most stress resistant had membranes enriched in saturated fatty acids, followed in order by cells enriched in oleic and linolenic acids. Aerobic cells with membranes enriched in palmitoleic and oleic acids showed the highest resistance to stress under all conditions. In both aerobic and anaerobic cells, a mild heat shock or oxidative shock induced markedly increased levels of thiobarbituric acid reactive substance (TBARS), indicative of malondialdehyde formation and lipid damage. Anaerobic cells with membranes enriched in linolenic acid had the highest TBARS, followed by cells enriched in oleic acid, with cells enriched in saturated fatty acids showing the lowest TBARS. The results suggest that heat and oxidative stress may share a common mechanism of damage through induction of oxygen-derived free radicals, resulting in membrane lipid damage.(ABSTRACT TRUNCATED AT 250 WORDS)

Relationships between thermotolerance, oxidative stress responses and induction of stress proteins in human tumour cell lines.

Thermotolerance, resistance to oxidative stress and induction of stress proteins were examined in a panel of 10 human tumour cell lines. An inverse relationship was indicated between intrinsic thermotolerance (cell survival after treatment at 43.5 degrees for 3 hr) and thermotolerance induced by pretreatment at 42.5 degrees for 30 min. Similar levels of induction of hsp 70 were found in cell lines with high or low levels of intrinsic thermotolerance; induction of other stress proteins could not be detected. Cell survival following treatment with H2O2 correlated with that following streptonigrin treatment (P < 0.05). Pretreatment with buthionine sulphoximine or diamide synergistically increased the toxicity of heat, H2O2 and streptonigrin whereas reduced glutathione had the reverse effect. No direct correlation was found, however, between tolerance to heat and to oxidative stress, and hsp 70 was not induced by the latter. The stress protein heme oxygenase, detected by immunoblotting with the monoclonal antibody HO, was induced by H2O2 in melanoma cell lines but not in HeLa. Cadmium and arsenite ions, however, readily induced heme oxygenase in HeLa, indicating that in these cells induction of heme oxygenase by oxidative stress involves a different mechanism. Overall, the results suggest that tolerance to heat or oxidative stress in these cell lines may not necessarily be associated with the induction of heat shock proteins or heme oxygenase but that cell survival after both types of stress depends to a certain extent on cellular sulphydryls.
