Background: Metastatic breast cancer (MBC) patients have numerous options for treatment. However, it is essential to consider treatments with favorable toxicity profiles and convenient modes of administration. Eribulin has shown effectiveness in aggressive MBC, but there is a lack of sufficient real-world data specific to Indian patients.

Purpose: For cervical cancer patients, intra-cavitary brachytherapy (ICBT) is utilized with various dose-rate systems, such as low-dose-rate (LDR), high-dose-rate (HDR), and pulsed-dose-rate (PDR). This retrospective analysis aimed to compare the therapeutic outcomes of cervical cancer patients treated with either LDR-, HDR-, or PDR-ICBT.

Material And Methods: A total of 613 patients were treated with pelvic external beam radiation therapy (EBRT), followed by either LDR- (271 patients), HDR- (259 patients), or PDR- (83 patients) ICBT.

Article Synopsis
  • The 2018 revision of the International Federation of Gynaecology and Obstetrics staging has introduced uncertainties in treatment approaches for node-positive cervical cancer patients, leading to a study aimed at identifying those who will benefit from elective para-aortic lymph node (PALN) irradiation.
  • This ongoing multicenter phase III clinical trial involves 274 subjects divided into two groups to compare the effectiveness of limited elective PALN irradiation against no irradiation, with a primary focus on 3-year disease-free survival and various secondary endpoints related to survival and quality of life.
  • The study has received ethical approval and is set to be monitored according to guidelines, with the intention to publish findings in reputable scientific journals.

Background: We developed and tested a dichoptic treatment designed for younger children that can be viewed freely and involves a dichoptic manipulation of a popular animation series that enables contrast-rebalancing without disrupting fusion. Our aim was to assess whether this novel amblyopia treatment is superior to patching in children aged 3-5 years.

Methods: A total of 34 children with amblyopia were randomly assigned to contrast-rebalanced dichoptic cartoons (4 hours/week) or patching (14 hours/week) for 2 weeks.

contains potential therapeutic capsaicinoids, and various stress factors influence plant productivity. Serotonin is an indoleamine involved in signaling several stress response mechanisms in plants. However, the influence of serotonin on cell growth and the accumulation of secondary metabolites, mainly capsaicinoids production, is not yet clearly defined under salt stress.

The treatment landscape for localized and regional prostate cancer includes active surveillance, radiation therapy (RT), and radical prostatectomy (RP). Population-based studies comparing RP to radiation reveal conflicting results due to methodological flaws. This systematic review and pooled analysis of studies aim to compare cause-specific survival (CSS), overall survival (OS), disease-free survival (DFS) and toxicity outcomes, comparing RP to RT in the management of prostate cancer.

Objectives: With sensitive imaging for breast cancer, the question arises whether present-day oncologists treat dOMBC with palliative systemic therapy (ST), which, a few years earlier, would have been treated with curative intent. We retrospectively analyzed outcomes of dOMBC treated with curative intent using a combination of surgery, metastasis-directed radiotherapy (RT), and adjuvant/neoadjuvant ST and have also explored the possible role of total lesional glycolysis of metastases and p53 immunohistochemistry in predicting outcomes.

Methods: Data were collected from a prospectively maintained database using electronic medical records and Radiation Oncology Information System.

(Malpighiaceae) is a cherry fruit popularly known as acerola or West Indian cherry, with nutraceuticals in each ripening stage. The changes in the phytoconstituents, pigments, sugars, organic acids, and antioxidants were investigated during the fruit ripening and expressed in fresh weight (FW). Gentisic acid was present in the highest concentration in IMGL fruits (11.

Chronic diarrhea and abdominal pain after radiotherapy continue to be a problem in cancer survivors. Gut microbiomes are essential for preventing intestinal inflammation, maintaining intestinal integrity, maintaining enterohepatic circulation, regulating bile acid metabolism, and absorption of nutrients, including fat-soluble vitamins. Gut microbiome dysbiosis is expected to cause inflammation, bile acid malabsorption, malnutrition, and associated symptoms.

Introduction: Low middle-income countries (LMICs), including India, have paucity of external beam radiotherapy (RT) machines leading to prolonged wait times for RT. Delay in delivery of RT has been shown to adversely affect outcomes in locally advanced breast cancer (LABC). With the availability of results of multiple randomized controlled trials, hypofractionated RT delivered over 3 to 4 weeks became the standard of care in breast cancer RT.

Background: To report 15-year incidence rate of primary open angle glaucoma (POAG) in the Andhra Pradesh Eye Disease Study (APEDS).

Methods: A population-based longitudinal study was carried out at three rural study sites. Phakic participants aged ≥40 years who participated at baseline (APEDS I) and the mean 15-year follow-up visit (APEDS III) were included.

The objective of this study was to investigate the physiological and biochemical effects of Chitosan nanoparticles on Capsicum annuum plants. The particle size, polydispersity index, composition, and structure of the synthesized chitosan-based nanoparticles (Chitosan (CS), Chitosan-Silver (CSAg), and Chitosan-Copper (CSCu) NPs) were determined by analyzing the zeta potential, FTIR, TEM, and XRD. The seedlings showed improved physiological and biochemical characteristics when 1, 10, and 20 ppm concentrations of nanoparticles (CS, CSAg, and CSCu) were used for 24-h seed priming.

Introduction: Adenomyosis is an ambiguous disorder causing a wide variety of implications from dysmenorrhea, heavy menstrual bleeding, and infertility to pregnancy complications. Adenomyosis is associated with altered endocrine and inflammatory milieu, resulting in impaired implantation and reduced fertility potential. It is also associated with increased incidence of obstetric complications such as miscarriage, antepartum hemorrhage, placental mal-position, hypertensive disorders, small for gestational age-intrauterine growth restriction (SGA-IUGR), cesarean section, preterm labor, preterm premature rupture of membranes (PPROM), and neonatal intensive care unit (NICU) admissions.

Anthocyanins are a subclass of flavonoids that are synthesized in the endoplasmic reticulum and then transported to the vacuole in plants. Multidrug and toxic compound extrusion transporters (MATE) is a family of membrane transporters that transport ions and secondary metabolites, such as anthocyanins, in plants. Although various studies on MATE transporters have been carried out on different plant species, this is the first comprehensive report to mine the Daucus carota genome to identify the MATE gene family.

  • Malignant gliomas, the most prevalent type of primary malignant brain tumors, are often treated with surgery followed by chemoradiation, but radiation can lead to a dangerous drop in circulating lymphocytes, linked to worse survival outcomes.
  • A systematic review of 19 studies and a meta-analysis of 12 revealed that patients with severe lymphopenia had a significantly higher risk of death (HR = 2.19) and a mean survival reduction of nearly 7 months compared to those without severe lymphopenia.
  • Factors such as photon therapy, larger radiation treatment areas, higher doses to the brain and hypothalamus, and being female were found to increase the risk of developing severe lymphopenia.

Background: Radiation-related lymphopenia has been associated with suboptimal tumor control rates leading to inferior survival outcomes. To date, no standardized dose constraints are available to limit radiation dose to resident and circulating lymphocyte populations. We undertook this systemic review of the literature to provide a synopsis of the dosimetric predictors of radiation-related lymphopenia in solid malignancies.
