Article Synopsis
  • - Hydrogen sulfide (HS) is a toxic gas that workers in oil refineries often inhale, potentially affecting their health, although the long-term impact of low-level exposure is not well understood.
  • - A study involving 80 participants, including 40 oil refinery workers and 40 controls, measured urinary levels of HS-related metabolites, finding that DMSO was present in all samples, but the other metabolite TMS showed no significant difference between groups.
  • - The research indicated that while DMSO levels were higher in workers exposed to HS, the metabolites measured may not be sensitive enough to accurately reflect the low levels of HS inhalation in an occupational setting.

Article Synopsis
  • No significant connection has been previously reported between atrial septal defects (ASD) and cardiac myxomas, but this study presents a case of a 56-year-old woman who developed a cardiac myxoma following ASD closure.
  • After experiencing symptoms like dizziness and palpitations three months post-surgery, imaging revealed a large mass in her left atrium, which was later confirmed as an atrial myxoma through surgery and histopathological examination.
  • The case highlights the diagnostic difficulties in differentiating between a benign myxoma and a harmful thrombus, emphasizing that while there's no established link between ASD closure devices and myxoma formation, it remains a possible risk.

Article Synopsis
  • Plants produce various chemical defence compounds, which can differ across species, and the study explores how clover can benefit from these compounds produced by nearby plants.
  • In experiments, clover seedlings were exposed to specific benzoxazinoid compounds found in cereals, which resulted in increased resistance to root-knot nematodes for up to six weeks after being transplanted into soil.
  • The research suggests that by co-cultivating different crop species that can share and transform chemical defences, farmers could enhance plant protection against pests.

Port-A-Cath (port), a single-lumen, tunneled catheter, is routinely placed into the superior vena cava (SVC) for cancer patients undergoing chemotherapy. We present a case of a port placement in which variant anatomy was discovered during the fluoroscopy-guided procedure and confirmed by venogram of a persistent left-sided SVC (PLSVC). Upon further investigation into the patient's previous computed tomography (CT) scans, the diagnosis was further confirmed.

Article Synopsis
  • Hydatid cysts are rare in cytologic smears, often misdiagnosed, as seen in a case where fine needle aspiration cytology revealed a pulmonary hydatid cyst mistakenly thought to be an abscess.
  • A 29-year-old female with respiratory symptoms underwent imaging that suggested an abscess, but fine needle aspiration confirmed the presence of a hydatid cyst, leading to successful surgical removal.
  • The report emphasizes the importance of accurate diagnosis using various methods, highlighting fine needle aspiration as a valuable, though risky, tool when done by skilled professionals.

Pacemaker and implantable cardioverter defibrillator migration to the breast are an extremely rare complication. The rarity of this phenomenon and its potential to mimic breast cancer emphasize the importance of reporting such cases. This study presents a rare migration of the device to the breast tissue that clinically mimicked breast cancer.

Article Synopsis
  • Immunotherapy has improved outcomes for patients with metastatic melanoma but has revealed new response patterns, increasing the need for better biomarkers to predict patient benefits and side effects.
  • A literature review of 12 studies up to early 2022 focused on the role of artificial intelligence (AI) in analyzing melanoma patients treated with immunotherapy, showing CT imaging was most commonly used.
  • Most studies aimed to develop AI tools for predicting treatment responses and outcomes, though validation methods varied, highlighting the necessity for more robust testing with diverse patient groups for future integration into clinical settings.

Introduction: There are multiple management modalities for idiopathic granulomatous mastitis, but the treatment of choice is still under debate. This study aims to evaluate the diagnosis and outcomes of different management modalities in patients with idiopathic granulomatous mastitis and to identify the risk factors associated with recurrence.

Method: This is a single-group cohort study that included those patients who had idiopathic granulomatous mastitis.

Metabolomic studies on root uptake and transformation of bioactive compounds, like cereal benzoxazinoids (BXs) in non-BX producing plants, are very limited. Therefore, a targeted mass-spectrometry-based metabolomics study was performed to elucidate the root uptake of BXs in white clover ( L.) and the impact of absorbed BXs on intrinsic clover secondary metabolites.

Article Synopsis
  • Phytotoxins, specifically toxic alkaloids, are produced by lupins and other Fabaceae family plants, but their environmental effects remain largely unexplored.
  • A field experiment measured the presence of these alkaloids in various samples including lupin tissues and drainage water, with lupanine being the most prevalent compound detected.
  • The cumulative amount of alkaloids found in drainage water was minimal compared to the total in lupin biomass, but significant amounts were transported during heavy rainfall, highlighting potential contamination risks for surface water in agricultural regions.

Phytotoxins - toxins produced by plants - are contaminants with the potential to impair drinking water quality. They encompass a large group of toxic, partially persistent compounds that have been detected in seepage waters and in shallow wells used for drinking water production. If phytotoxins enter wells used for drinking water production, it is essential to know if the drinking water treatment processes will remove them from the water phase.

Phytotoxins are naturally produced toxins with potencies similar/higher than many anthropogenic micropollutants. Nevertheless, little is known regarding their environmental fate and off-field transport to streams. To fill this research gap, a network of six basins in the Midwestern United States with substantial soybean production was selected for the study.

Heavy metal pollution in the environment has gained interest in the past few decades, as it has been found to accumulate in soil and water, as well as in the human body. Heavy metals present a serious health risk to humans when the concentration level and exposure time are increased. Although they have been extensively studied in the environment and food, little is known regarding their occurrence in the Kurdistan Region of northern Iraq.

Pyrrolizidine alkaloids (PAs) are persistent mutagenic and carcinogenic compounds produced by many common plant species. Health authorities recommend minimising human exposure via food and medicinal products to ensure consumer health and safety. However, there is little awareness that PAs can contaminate water resources.

If pulse pressure, one of the mechanical stresses, is a risk factor for atherosclerotic cardiovascular disease, then atherosclerosis should be progressive in aortic regurgitation which is a representative disease with increased pulse pressure. This cross-sectional study included 1,149 patients. We examined the influence of aortic regurgitation on maximum intima-media thickness or brachial-ankle pulse wave velocity.

Amyloidosis is a well-known but uncommon disease, and the physician must maintain a high index of suspicion in order to make a timely diagnosis. The expected survival of patients with cardiac amyloidosis is generally poor. In particular, survival has been reported to be 4-12 months for patients with amyloid light-chain amyloidosis with congestive heart failure.

Background: Although fever is a common accompanying feature of acute aortic dissection, few reports have been published concerning the duration and character of this fever.

Methods And Results: The mean duration of fever was calculated for a total of 57 patients with acute aortic dissection, who were then divided into 2 groups: those with duration of fever shorter than the mean (Group A) and those with duration of fever equal to or longer than the mean (Group B). The reduction in false lumen size and hematological parameters were compared between groups.
