Seed Storage Protein Profiles in Cultivars of Capsicum annuum L.

SDS-PAGE protein profile patterns were studied from seed material of 10 cultivars of C. annuum L. A total of 15 protein polypeptide bands with molecular weights ranging from 22.4 to 80.8kD were recorded. On the basis of seed protein banding nature three varieties could be identified clearly viz., (CA2, CA4 and CA5). Among the varieties CA9 manifested maximum (9) number of protein bands. The greatest similarity (100%) was observed between CA6 and CA7, while the lowest (40%) was noted between (CA3-CA6), (CA3-CA7) and (CA3-CA10). The UPGMA dendrogram represented low genetic diversity. The study revealed that large intra-specific differences were not found in the cultivars, but presence of considerable variations in protein profiles of the cultivars suggested that these selected varieties can be a good source for crop improvement through hybridization programs

Phenolics Quantification in some Genotypes of Capsicum annuum L

Total phenolic contents of fruits at three ripening stages (green, intermediate and red) from nine genotypes of Capsicum annuum L. were analyzed. Among the genotypes C. annuum var. Paprika (C.a.2) had highest amount of phenolic contents i.e., 188.0±0.44, 220.0±0.52 and 266.0±0.30mg/100gFW from green, intermediate and red ripening respectively. The study revealed that high content of phenolics were found in fruits at red ripening. The variability of phenolic contents in the genotypes suggests that these selected genotypes may be use full as parents in hybridization programs to produce fruits with good nutritional values.Key words: Chili pepper, Gallic acid, Phenolics, Ripening O.

The documented of these medicinal plants against asthma reveals that these ethnic people are still dependent on local vegetation for their life care. Thus, this type of ethnomedicinal study appears to be useful for the research on medicinal plants for the betterment of mankind

The first steps in the development of a cancer-specific patient-reported experience measure item bank (PREM-item bank):towards dynamic evaluation of experiences

Objective: Since the implementation of value-based healthcare, there has been a growing emphasis on utilizing patient-reported experience measures (PREMs) to enhance the quality of care. However, the current PREMs are primarily generic and static, whereas healthcare is constantly evolving and encompasses a wide variety of aspects that impact care quality. To continuously improve care requires a dynamic PREM. The aim of this study was to propose an item bank for the establishment of a dynamic and care-specific patient-reported evaluation. Methods: In co-creation with patients, a mixed methods study was conducted involving: (1) an explorative review of the literature, (2) a focus group analysis with (ex-)patients, (3) qualitative analyses to formulate themes, and (4) a quantitative selection of items by patients and experts through prioritization. Results: Eight existing PREMs were evaluated. After removing duplicates, 141 items were identified. Through qualitative analyses of the focus group in which the patient journey was discussed, eight themes were formulated: “Organization of healthcare,” “Competence of healthcare professionals,” “Communication,” “Information &amp; services,” “Patient empowerment,” “Continuity &amp; informal care,” “Environment,” and “Technology.” Seven patients and eleven professionals were asked to prioritize what they considered the most important items. From this, an item bank with 76 items was proposed. Conclusion: In collaboration with patients and healthcare professionals, we have proposed a PREM-item bank to evaluate the experiences of patients’ receiving cancer care in an outpatient clinic. This item bank is the first step to dynamically assess the quality of cancer care provided in an outpatient setting.</p

Learnings From Longitudinal Patient-Reported and Clinical Outcomes in Palliative Head and Neck Cancer Care

Objective: Patients with palliative head and neck cancer experience many symptoms in a short period of time. Longitudinal data on patient-reported outcomes in this phase are lacking. The aim of this study is to use structurally obtained patient-reported outcome data combined with clinical patient data and obtain insight in patient-reported outcomes, survival, circumstances of death, and interventions and treatment during the palliative phase in order to improve the quality of end-of-life care and patient-centered counseling. Study Design: Longitudinal observational cohort study. Setting: Tertiary cancer center. Method: Quality of life was prospectively collected using the European Organization for Research and Treatment of Cancer QLQ-C15-PAL. Tumor- and patient-specific data were retrospectively collected. Descriptive statistics, linear mixed models, and regression analyses were performed. Results: A significant deterioration was found in global health status, physical functioning, fatigue, dyspnea, appetite loss, and constipation over time. However, emotional functioning improved. Median survival was 5.1 months, and only a low percentage of in-hospital death was observed (7.8%). Higher global health status at intake was associated with prolonged survival. Conclusion: Structural measurement of patient-reported outcome together with clinical outcomes provides unique insight, which enables improvement of patient-centered counseling and care.</p

Reconstruction of Partial Hypopharyngeal Defects following Total Laryngectomy:A Systematic Review and Meta-Analysis

Background: Various operative techniques exist to reconstruct partial hypopharyngeal defects following total laryngectomy. The current study aimed to investigate and compare complications and functional results following commonly used reconstructive techniques. Methods: A systematic review and meta-analysis were performed using studies that investigated outcomes after the reconstruction of a partial hypopharyngeal defect. The outcomes of interest were fistulas, strictures, flap failure, swallowing function and postoperative speech. Results: Of the 4035 studies identified, 23 were included in this review. Four common reconstructive techniques were reported, with a total of 794 patients: (1) pectoralis major myocutaneous and (2) myofascial flap, (3) anterolateral thigh free flap and (4) radial forearm free flap. Fistulas occurred significantly more often than pectoralis major myocutaneous flaps (34%, 95% CI 23–47%) compared with other flaps (p &lt; 0.001). No significant differences in the rates of strictures or flap failure were observed. Pectoralis major myofascial flaps were non-inferior to free-flap reconstructions. Insufficient data were available to assess speech results between flap types. Conclusion: Pectoralis myocutaneous flaps should not be the preferred method of reconstruction for most patients, considering their significantly higher rate of fistulas. In contrast, pectoralis major myofascial flaps yield promising results compared to free-flap reconstructions, warranting further investigation.</p

Detecting head and neck lymph node metastases with white light reflectance spectroscopy; a pilot study

Introduction: A challenge in the treatment of patients with head and neck cancer is the management of occult cervical lymph node (LN) metastases. Single-fiber reflectance (SFR) spectroscopy has the potential to detect physiological tissue changes that occur in a positive LN. This pilot study aimed to investigate whether SFR spectroscopy could serve as an alternative or additional technique to detect cervical lymph node metastases. Materials and Methods: We performed intraoperative SFR spectroscopy measurements of LNs with and without malignancies. We analyzed if physiological and scattering parameters were significantly altered in positive LNs. Results: Nine patients with a total of nineteen LNs were included. Three parameters, blood volume fraction (BVF), microvascular saturation (StO2), and Rayleigh amplitude, were significantly lower in positive LNs. They were combined into one optical parameter ‘delta’, using discriminant analysis. Delta was significantly decreased in positive LNs, p = 0,0006. It had a high diagnostic accuracy where the sensitivity, specificity, PPV, and NPV were 90,0%, 88.9%, 90,0%, and 88.9%, respectively. The area under the ROC curve was 96.7% (95% confidence interval 89.7–100.0%). Conclusion: This proof of principle study is a first step in the development of an SFR spectroscopy technique to detect LN metastases in real time. A next step towards this goal is replicating these results in LNs with smaller metastases and in a larger cohort of patients. This future study will combine SFR spectroscopy with fine-needle aspiration, using the same needle, to perform preoperative in vivo measurements.</p

Long-term outcomes, quality of life, and costs of treatment modalities for T1–T2 lip carcinomas

Purpose: Early stage lip squamous cell carcinoma (lip SCC) can be treated with conventional excision, Mohs micrographic surgery (MMS), or brachytherapy. The aim of this retrospective study was to describe the medical outcomes, patient-reported outcomes, and costs of these treatments. Methods: A retrospective cohort study of T1–T2 lip SSCs treated between 1996 and 2019. Medical outcomes, recurrences, and survival were retrieved from medical records. Facial appearance, facial function, and Quality of Life (QoL) were measured with the Face-Q H&amp;N and EQ-5D-5L questionnaires. Costs were also calculated. Results: Of the 336 lip SCCs, 122 were treated with excision, 139 with MMS, and 75 with brachytherapy. Locally, the recurrence rate was 2.7% and regionally 4.8%. There were 2% disease-related deaths. T2-stage and poor tumor differentiation were associated with recurrences. Posttreatment QoL, facial function, and appearance were rated as good. Brachytherapy was the most expensive treatment modality. Conclusion: Early-stage lip SCC has a good prognosis, with a disease-specific survival of 98.2% after a median follow-up of 36 months, there was a high QoL and satisfaction at long-term follow-up. Based on the costs and the risk of locoregional recurrences, we believe that, for most noncomplex lip SCCs, MMS would be the most logical treatment option.</p

Individualized Dynamic Prediction Model for Patient-Reported Voice Quality in Early-Stage Glottic Cancer

Objective: Early-stage glottic cancer (ESGC) is a malignancy of the head and neck. Besides disease control, preservation and improvement of voice quality are essential. To enable expectation management and well-informed decision-making, patients should be sufficiently counseled with individualized information on expected voice quality. This study aims to develop an individualized dynamic prediction model for patient-reported voice quality. This model should be able to provide individualized predictions at every time point from intake to the end of follow-up. Study Design: Longitudinal cohort study. Setting: Tertiary cancer center. Methods: Patients treated for ESGC were included in this study (N = 294). The Voice Handicap Index was obtained prospectively. The framework of mixed and joint models was used. The prognostic factors used are treatment, age, gender, comorbidity, performance score, smoking, T-stage, and involvement of the anterior commissure. The overall performance of these models was assessed during an internal cross-validation procedure and presentation of absolute errors using box plots. Results: The mean age in this cohort was 67 years and 81.3% are male. Patients were treated with transoral CO2 laser microsurgery (57.8%), single vocal cord irradiation up to (24.5), or local radiotherapy (17.5%). The mean follow-up was 43.4 months (SD 21.5). Including more measurements during prediction improves predictive performance. Including more clinical and demographic variables did not provide better predictions. Little differences in predictive performance between models were found. Conclusion: We developed a dynamic individualized prediction model for patient-reported voice quality. This model has the potential to empower patients and professionals in making well-informed decisions and enables tailor-made counseling.</p
