RESUMO

In 2020, 19.3 million new cancer cases were diagnosed, and almost 10 million deaths from cancer were recorded. Cancer patients may experience fatigue, depression, anxiety, reduced quality of life and sleep problems. Cancer treatments cause numerous side effects and have a negative impact on all body systems. Physical activity is important for cancer patients. The aim of this review is to analyse recent studies on the role of physical activity in cancer patients and emphasize its importance. The review included 36 papers published in English between 2017 and 2021. The findings from these studies show that physical activity decreases the severity of side effects of cancer treatment, reduces fatigue, improves quality of life, has a positive impact on mental health and improves aerobic fitness in cancer patients. Moreover, it reduces the risk of cancer recurrence and death. Physical activity is recommended for patients with any type of cancer and at all stages of treatment. The type of physical activity should depend on the condition of the individual patient. It is extremely difficult to determine what type, intensity and duration of physical activity is likely to have the greatest effect.

RESUMO

Primary hyperparathyroidism (PHPT) secondary to parathyroid gland adenoma is mildly symptomatic and thus often incidentally diagnosed. In this report, we present a case of a 46-year-old man who was treated for hypertension and other nonspecific complaints. An elevated level of blood calcium led to the suspicion of parathyroid adenoma. Technetium-99m-methoxyisobutylisonitrile (99mTc-MIBI) planar and single-photon emission computed tomographic scintigraphy (SPECT/CT) confirmed the presence of a 10-mm-wide adenoma behind the sternal handle in the anterior mediastinum. The tumor was excised by Kocher's cervical access along with the right and left upper horns of the thymus gland and was histologically confirmed as being of parathyroid nature. However, blood parathyroid hormone and calcium remained persistently elevated. Repeated scintigraphy imaging revealed the presence of another retrosternal tracer focus at the level of Ludwig's angle. The patient was reoperated with the longitudinal sternotomy access, and thymus remnants, parathymic nodule, and fragments of mediastinal fat and right parietal pleura were removed. On the second postoperative day, parathyroid hormone and calcium reverted to normal values, but the patient remained hypertensive. Despite the successful surgical treatment, the patient remained hypertensive suggesting that the underlying reason was a familial hypertensive disease rather than parathyroid adenoma. In conclusion, this report underscores the need for diagnostic vigilance in the case of persisting hypercalcemia with hypertension and diagnostic and surgical difficulties in the management of ectopic PHPT secondary to parathyroid gland adenomas.

RESUMO

INTRODUCTION: Diabetes mellitus is one of the most common chronic diseases with a high number of sufferers worldwide. Diabetic neuropathy and diabetic angiopathy lead to serious infectious complications which are very difficult to combat and may finally lead to the amputation of a lower limb. The aim of the study was to evaluate the quality of life, the level of acceptance of the illness and the nutritional status of patients after lower limb amputation due to diabetes. METHODS: Ninety-nine patients (23 men and 76 women) were enrolled into the study. They had all undergone lower limb amputation due to diabetic foot and were treated in the Department of General and Oncological Surgery. The following questionnaires were used: the WHO Quality of Life-BREF (WHOQOL-BREF), the Mini Nutritional Assessment (MNA), the Acceptance of Illness Scale (AIS) and the anonymous specific socio-demographic characteristics questionnaire. RESULTS: The diabetes-related amputees were revealed to have a higher QoL within the social domain (mean score 64.48), an intermediate QoL - within the environmental domain (mean score 63.04) and the mental domain (mean score 59.61), and a lower QoL - within physical (somatic) domain (mean score 54.69). There was no statistical correlation between genders or between all the domains of QoL (P > 0.05). The mean MNA score was 22.66, which means that patients were at risk of malnutrition. There were statistical differences between women and men as regards nutritional status (P = 0.034). The mean AIS score was 27.65 (27.09 women and 29.48 men), which means that the respondents accept their disease. There was no statistical correlation between gender and the acceptance of the disease (P = 0.288). There was not statistical correlation between age and QoL (P > 0.05). There were statistical differences between age and nutritional status (P < 0.05), and between age and acceptance of the illness (P = 0.044). CONCLUSIONS: The better the quality of life was in all the domains, the better the level of acceptance of illness was. The less malnourished the patient was, the better their quality of life was in all the domains.

RESUMO

Lung cancer, colon cancer, breast cancer, and prostate cancer are the leading causes of death in developed countries. Many cancers display non-specific signs in the early stage of the disease, thus making early diagnosis often difficult. We focused on nestin as a new biomarker of possible clinical importance in the early diagnosis and monitoring of cancer. The expression of nestin takes place at an early stage of neural differentiation, but no expression of the nestin gene can be revealed in normal, mature adult tissues. Nestin plays an important role in the development of the central nervous system and contributes to the organization and maintenance of cell shape. Nestin was found to be a marker of microvessel density, which in turn has proven to be a reliable prognostic factor for neoplastic malignancies in patients. Nestin expression correlates with an increased aggressiveness of tumor cells. The role of nestin in cancers of the colon and rectum, liver, central nervous system, lung cancer, breast cancer, melanoma, and other cancers has been reviewed in the literature. Associations between nestin expression and prognosis or drug-resistance may help in disease management. More research is needed to understand the molecular mechanisms of nestin expression and its role in possible targeted therapy.

RESUMO

The aim of this study was to evaluate the parameters of visual and brainstem auditory evoked potentials in patients occupationally exposed to arsenic, cadmium and lead. The study group comprised 41 copper smelter and refinery workers (average age: 51.27) with occupational exposure to arsenic, cadmium and lead. The control group consisted of 36 healthy volunteers (35 men and 1 woman, aged 27-66, average age: 51.08). Neurological examination, brain imaging, and visual and brainstem auditory evoked potentials were performed, and the relationship between blood Cd, Pb concentration (Cd-B, Pb-B), blood zinc protoporphyrin (ZnPP), and urine As concentration (As-U) were assessed. In the workers, exceedances of allowable biological concentrations were observed, with the urinary concentration of arsenic being 5.2%, the cadmium and lead in blood being 1.3%, while the case of ZnPP was 2.6%. The mean P100, relative P100, and N145 visual evoked potential (VEP) latencies were significantly longer in exposed workers than in the controls. The mean wave III and V brainstem auditory evoked potential (BAEP) latency and the mean wave III-V and I-V interpeak latencies were longer, and the I and V amplitude was lower in the workers than the controls. In summary, occupational exposure to As, Cd, and Pb is associated with prolonged latency and reduced evoked potential amplitude, but As-U, Pb-B, Cd-B, and ZnPP concentrations are not linearly related to potential components. The analysis of evoked potentials may be a useful method of assessment of the central nervous system in patients with occupational exposure to heavy metals.

RESUMO

The purpose of this work was to assess the influence of selected CNR1, MC4R, LEP, FTO and VDR FOKI gene polymorphisms on blood and urine concentration markers of lead, cadmium and arsenic in a population directly exposed to these metals. Eighty-five people exposed to lead, arsenic and cadmium were qualified to take part in the study. Standard urine samples and 25mL of venous blood from each worker were collected to assay basic laboratory and toxicological markers as well as selected single nucleotide polymorphisms (SNPs) within CNR1-cannabinoid receptor 1 gene (rs806368, rs806381, rs1049353, rs12720071), MC4R-melanocortin 4 receptor gene (rs17782313), LEP-leptin promoter gene (rs7799039), FTO-alpha-ketoglutarate-dependent dioxygenase gene (rs9939609) and VDR-vitamin D receptor (rs10735810) genes. It appeared that, except for the MC4R SNP, all the other polymorphisms were found to be associated with various laboratory parameters. Arsenic concentration in urine was associated with all four CNR1 and LEP SNPs, while cadmium concentration in blood was affected by the VDR polymorphism. Moreover, some significant relationships were also observed between CNR1 rs1049353 and FTO rs9939609 gene variants and markers of lead exposure. These results imply SNPs within genes coding for proteins involved in development of metabolic syndrome may be of prognostic value for persons directly exposed to lead, cadmium and arsenic.

RESUMO

Colorectal cancer is the third most commonly diagnosed cancer in males and the second most common in females. Only 10-20% of patients are diagnosed at the early stage of disease. Recently, the role of novel biomarkers of the neoplastic process in the early detection of colorectal cancer has been widely discussed. In this review, we focused on the three novel biomarkers that are of potential clinical importance in diagnosing and monitoring colorectal cancer. Chitinase 3-like 1 protein, also known as YKL-40, and nestin and testin proteins are produced by colorectal cancer cells. YKL-40 protein is a marker of proliferation, differentiation, and tissue morphogenetic changes. The level of YKL-40 is elevated in about 20% of patients with colorectal cancer. An increased expression of nestin indicates immaturity. It is a marker of angiogenesis in neoplastic processes. Testin protein is a component of cell-cell connections and focal adhesions. The protein is produced in normal human tissues, but not in tumor tissues. Downregulation of testin increases cell motility, spread, and proliferation, and decreases apoptosis. The usefulness and role of these biomarkers, both alone and combined, in the diagnostics of colorectal cancer should be further explored as early cancer detection may substantially improve treatment outcome and patient survival.

RESUMO

Thyroid hormones are essential for body homeostasis. The scientific literature contains restricted proofs for effects of environmental chemical factors on thyroid function. The present study aimed at evaluating the relationship between toxicological parameters and concentration of thyrotropic hormone in persons occupationally exposed to lead, cadmium and arsenic. The studies were conducted on 102 consecutive workers occupationally exposed to lead, cadmium and arsenic (mean age 45.08 ± 9.87 years). The estimated parameters characterizing occupational exposure to metals included blood cadmium concentration (Cd-B), blood lead concentration (Pb-B), blood zinc protoporphyrin concentration (ZnPP) and urine arsenic concentration (As-U). Thyroid function was evaluated using the parameter employed in screening studies, the blood thyrotropic hormone concentration (TSH). No differences were disclosed in mean values of toxicological parameters between the subgroup of persons occupationally exposed to lead, cadmium and arsenic with TSH in and out of the accepted normal values. Logistic regression demonstrated that higher blood total bilirubin concentrations (ORu = 4.101; p = 0.025) and higher Cd-B (ORu = 1.532; p = 0.027) represented independent risk factors of abnormal values of TSH in this group. In conclusion, in the group of workers exposed to lead, cadmium and arsenic, higher blood cadmium concentration seems to augment the risk of abnormal hormonal thyroid function.

RESUMO

INTRODUCTION: Meckel's diverticulum is the most common congenital anomaly of the gastro intestinal tract, present in about 2% of population. CASE OUTLINE: The article presents the case of a 44-year-old otherwise healthy man with anemia, who was diagnosed lower gastrointestinal bleeding. An abdominal CT scan revealed a clearly demarcated solid tumor in hypogastric region, measuring 65 x 45 mm. A laparotomy through lower midline incision was performed. A surgical resection of a lesion of a Meckel's diverticulum was carried out and a final diagnosis of gastrointestinal stromal tumor was made.The patient made an uneventful recovery. CONCLUSION: The preoperative diagnosis of a complicated Meckel's diverticulum may be challenging. CT is usually an adequate method to diagnose tumors arising from Meckel's diverticulum.

RESUMO

Lung cancer is the major cause of oncologic-related death worldwide. Due to delayed diagnosis, 5-year survival rate accounts for only 15%. Treatment includes surgery, adjuvant chemotherapy, and radiation therapy; however, it is burdened by many side effects. Progress of the disease, severity of its symptoms, and side effects decrease significantly the quality of life (QoL) in those patients. The level of self-assessed QoL helps in predicting survival, which is especially important among patients receiving palliative care. Patients assess their functioning in five dimensions (physical, psychological, cognitive, social, and life roles), severity of symptoms, financial problems, and overall QoL. The QoL in lung cancer patients is lower than in healthy population and patients suffering from other malignancies. It is affected by the severity and the number of symptoms such as fatigue, loss of appetite, dyspnea, cough, pain, and blood in sputum, which are specific for lung tumors. Fatigue and respiratory problems reduce psychological dimension of QoL, while sleep problems reduce cognitive functioning. Physical dimension (related to growing disability) decreases in most of the patients. Also, most of them are unable to play their family and social roles. The disease is a frequent reason of irritation, distress, and depression. Management of the disease symptoms may improve QoL. Controlling the level of fatigue, pulmonary rehabilitation, and social and spiritual support are recommended. Early introduction of tailored palliative treatment is a strategy of choice for improvement of QoL in lung cancer patients.

RESUMO

The main factor of environmental contamination is the presence of the heavy metals lead, cadmium, and arsenic. The aim of serum protein profile analysis of people chronically exposed to heavy metals is to find protein markers of early pathological changes. The study was conducted in a group of 389 healthy men working in copper foundry and 45 age-matched non-exposed healthy men. Toxicological test samples included whole blood, serum, and urine. Thirty-seven clinical parameters were measured. Based on the parameters values of the healthy volunteers, the centroid in 37-dimensional space was calculated. The individuals in the metal-exposed and control groups were ordered based on the Euclidean distance from the centroid defined by the first component according to Principal Component Analysis (PCA). Serum samples of two individuals, one from the control and one from the metal-exposed group, were chosen for proteomic analysis. In optimized conditions of two-dimensional gel electrophoresis (2-DE), two protein maps were obtained representing both groups. Twenty-eight corresponding protein spots from both protein maps were chosen and identified based on PDQuest analysis and the SWISS-2DPAGE database. From a panel of six proteins with differences in expression greater than a factor of two, three potential markers with the highest differences were selected: hemoglobin-spot 26 (pI 7.05, Mw 10.53), unidentified protein-spot 27 (pI 6.73, Mw 10.17), and unidentified protein-spot 25 (pI 5.75, Mw 12.07). Further studies are required to prove so far obtained results. Identified proteins could serve as potential markers of preclinical changes and could be in the future included in biomonitoring of people exposed to heavy metals.

RESUMO

OBJECTIVE: Molecular epidemiology studies have lately been focused on occupational cancer associated with exposure to chemical carcinogens in work environment. Measuring serum levels of tumour markers ie. the substances produced in transformed cells, is a modern method used in the prevention or early detection of cancer. A two-year observation study was constructed to investigate the relationship between arsenic, lead, and cadmium concentrations and the levels of cancer markers: TPA (tissue polipeptide antigen), TPS (tissue polipeptide specific antigen), and CYFRA 21-1 in 69 male workers occupationally exposed to As and Pb, and environmentally exposed to Cd via tobacco smoking. RESULTS: Significant correlations were found between CEA and blood Cd concentrations or between CEA and period of work under exposure. Multiple regression tests revealed also relationships between some cancer markers and the work period, and thereby the lifetime exposure to heavy metals. Duration of work under exposure significantly influenced TPA and TPS concentrations in these models. All the metals examined were found to have influence on the concentration of cancer markers, except for CYFRA 21-1, but the direction of this influence varied. Lead (especially FEP level) and cadmium were also among the metals affecting TPA concentration profile, although the multiple regression ratio for Cd-TPA correlation was negative. CONCLUSIONS: The strong positive correlation between blood concentrations of Cd and CEA, the marker of abnormal cellular differentiation, may reflect neoplastic transformation of normal cells stimulated by some carcinogens (e.g. cadmium). All the examined carcinogenic, or potentially carcinogenic metals (As, Cd, Pb) belong to the group of factors having impact on serum TPS and/or TPA concentrations in exposed workers. No correlation was found between CYFRA 21-1 and any metal studied but it is plausible that changes in the concentration level of this marker might be revealed after a longer observation period.

RESUMO

BACKGROUND: Industrial development increases the threat to human health caused by chemical contamination of the environment. Occupational neoplasms induced by exposure to carcinogenic factors present in workplaces are one of its effects. Heavy metals, especially arsenic, play an important role in this process. The aim of the study was to assess potential carcinogenic effects of arsenic and other heavy metals and the relation between their concentrations in organic fluids and the level of specific neoplastic markers, which might indicate the risk of the development of occupation-related neoplastic diseases. MATERIALS AND METHODS: Over two years, 224 men employed in the "Legnica" Copper Foundry, Divisions of Furnace Charge Preparing and Metallurgy, were examined. Plasma and urine concentrations of some metals and neoplastic markers were measured. We analyzed a possible correlations between metals and markers concentrations. RESULTS AND CONCLUSIONS: The study allowed to establish a strong positive correlation between urine arsenic concentration, blood cadmium concentration and some serum neoplastic markers (CEA, SCC-Ag, PSA). There was a distinct synergistic reaction between the levels of arsenic, cadmium and lead intoxication and the number of smoked cigarettes, so that smoking copper smelters exposed to these metals form a high cancer risk group. Significant positive correlation between blood lead concentration, free erythrocyte protoporphyrins and the level of arsenic in copper smelters might indicate the increased risk of late effects of intoxication in persons under combined exposure to these metals.

RESUMO

This paper gathers data on the most current aspects of arsenic action, especially its influence on the cardiovascular system, blood and bone marrow. A potential carcinogenic mechanism of arsenic is also discussed. Arsenic is a potent toxicant that may exist in several valencies and in a number of inorganic and organic forms. Most cases of arsenic-induced toxicity in humans are due to exposure to inorganic arsenic, and there is an extensive database on the human health effects of common arsenic oxides and oxyacids. Exposure of humans living near hazardous waste sites may involve inhalation of arsenic dusts in the air, ingestion of arsenic in water, food or soil, or dermal contact with contaminated soil or water. The exposure to arsenic via the inhalation route is responsible for the increased risk of lung cancer, although respiratory irritation, nausea and skin effects may also occur. The oral route of exposure to arsenic predominates in the general population. The most common effects of arsenic ingestion are gastrointestinal irritation, peripheral neuropathy, vascular lesions, anemia, skin diseases, including skin cancer and other cancers of the internal organs like bladder, kidney, liver or lung. Relatively little information is available on the effects of direct dermal contact with inorganic arsenicals, but several studies indicate local irritation and dermatitis as the major ones.
