Occurrence Of Depression In Patients Research Articles

Association Between Serum Magnesium Levels and Depression in Patients Undergoing Peritoneal Dialysis: A Study Conducted at Handan First Hospital, China.

Depression exhibits notable prevalence among patients affected by chronic kidney disease(CKD) and end-stage renal disease (ESRD). Emerging reports suggest a potential association between magnesium (Mg) levels and depressive symptoms, there has been a surge of interest in exploring Mg supplementation as a complementary measure in depression treatment. In this study our aim is to investigate the correlation between depressive symptoms and serum Mg level in patients undergoing peritoneal dialysis (PD) at Handan First Hospital, China. Additionally, we assessed the diagnostic significance of this relationship and identified pertinent influencing factors. This study comprises a cohort of 140 individuals undergoing PD for a minimum duration of 3 months at the PD center of the Handan First Hospital. The Hamilton Depression Scale (HAMD) served as the assessment tool to evaluate the psychological status of the patients. Serum Mg levels, hemoglobin (Hb), and various demographic and clinical data were collected. Logistic regression and ROC analysis were performed to identify significant predictors of depression. The prevalence of depression was higher in patients with hypomagnesemia (60%) compared to those with normal or elevated Mg levels. Notably, a correlation emerged between abnormal serum Mg levels and the presence of depressive symptoms among individuals undergoing PD. Furthermore, binary logistic regression analysis revealed that serum Mg levels, hemoglobin (Hb) concentration, and unemployment significantly influenced the likelihood of occurrence of depression in patients undergoing PD (P< 0.05). In addition, serum Mg levels demonstrate significant predictive value in anticipating onset of depression, indicating that rectifying low serum Mg levels among patients undergoing PD may serve as a preventive measure against depression. Further research is recommended to explore the therapeutic potential of Mg supplementation in this population.

Clinical and Sociodemographic Characteristics of Depressive Symptoms in a Sample of Egyptian Patients with Schizophrenia

Abstract Background Schizophrenia is a major psychiatric illness across the world, severely affecting the quality of life, and could be commonly associated with depressive symptoms, although its underlying pathology is still unclear and recently multiple studies were concerned with the relation between Schizophrenia and depressive symptoms. Objective To determine the rate of occurrence of depression in patients with Schizophrenia &amp; assess the relation between the sociodemographic and clinical characteristics of patients with Schizophrenia with depressive symptomatology. Patients and Methods This was an analytical cross-sectional study; carried out at Okasha Institute of Psychiatry, between September 2023 to March 2024. Results There was no statistically significant difference found between patients with and without depression, as confirmed or excluded by the CDSS, regarding PANSS and SANS scores. There was no statistically significant correlation between depressive symptoms in patients with Schizophrenia and the mentioned sociodemographic and clinical characteristics except for male gender as a protective independent factor and duration of illness ≥ 8 years as an independent risk factor. Further investigations via longitudinal studies and on larger samples are recommended to settle specific causal paths between the two variables. Conclusion Our study revealed that the male gender is a protective independent factor for depression in patients with schizophrenia and that the duration of illness ≥ 8 years is an independent risk factor for depression in schizophrenia. Yet, there are no other statistically significant sociodemographic or clinical characteristics associated with depressive symptoms in patients with Schizophrenia.

Prevalence and Correlates of Depressive Symptoms among Patients with Cancer: A Cross-Sectional Study.

The purpose of this study was to identify the correlates of depressive symptoms and the prevalence of depression, distress, and demoralization among patients with cancer in Taiwan in relation to their sociodemographics. A cross-sectional study design with convenience sampling was used to recruit 191 consecutive patients with cancer from the Cancer Center of a teaching hospital in northern Taiwan. Multiple linear regression was applied to analyze the determinants of depressive symptoms. The prevalence rates of depression (including suspected cases), distress, and demoralization were 17.8%, 36.1%, and 32.5%, respectively. The regression model explained 42.2% of the total variance, with significant predictors including marital status, life dependence, comorbidity, demoralization, and distress. The results demonstrated that higher levels of distress and demoralization were associated with more depressive symptoms. Demoralization and distress played vital roles in moderating depressive symptoms among patients with cancer. Nursing interventions should integrate appropriate mental health services, such as alleviating distress and demoralization, to prevent the occurrence of depression in patients with cancer.

Association between physical activity and sedentary behavior and depression in US adults with cardiovascular disease: NHANES 2007–2016

BackgroundPrevious studies reported the effect of physical activity (PA) or sedentary behavior (SB) on increasing occurrence of depression in patients with cardiovascular disease, leading to a higher risk of adverse clinical outcomes. However, the association between the combination of PA and SB and depression in patients with cardiovascular disease remained unstudied. MethodsPatients with cardiovascular disease (aged ≥18 years) who participated in the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2016. Multivariable logistic regression was used to investigate the association between PA, SB, and depression. ResultsAmong the 2585 patients (mean age 64.43 years; 54.65 % male) in this study, the prevalence of depression was 16.40 %. After adjustment for age, gender, race, education level, marital status, poverty income ratio, employment status, smoking, alcohol use, BMI, hypertension, and number of cardiovascular diseases, depression was negatively associated with higher PA (adjusted OR = 0.567, 95 % CI 0.403, 0.799) and positively associated with higher SB (adjusted OR = 1.472, 95 % CI 1.089, 1.990), respectively. The risk of depression associated with higher PA and lower SB was significantly lower (adjusted OR = 0.464, 95 % CI 0.307, 0.702) compared to those with lower PA but higher SB. LimitationsThis was a cross-sectional study with limited ability to make causal inferences. ConclusionsOur findings indicate that patients with higher PA and lower SB have a lower risk of depression than those with low PA levels and high SB levels. Moving more and sitting less is a potential preventive measure against depression in patients with cardiovascular disease.

Correlation of Specific Inflammatory Markers With the Occurrence of Depression in Patients With Psoriasis and Their Use as Biomarkers for the Diagnosis of Depression.

Psoriasis is a systemic disease of the skin and nails associated with a wide range of comorbidities such as depression, psoriatic arthritis and metabolic syndrome. The study aimed to examine a potential association between inflammatory markers (C- reactive protein [CRP] and erythrocyte sedimentation rate [ESR]) and depression in patients with psoriasis. A total of 80 individuals were enrolled in the study. Case participants included 28 patients diagnosed with Psoriasis (Beck Depression Inventory-II: :0-13) and 24 patients diagnosed with Psoriasis and Depression (Beck Depression Inventory-II:14-63). Twenty-eight (28) healthy participants comprised the control group.Psoriasis severity was evaluated by using Psoriasis Area and Severity Index, Physician Global Assessment, Body Surface Area and Dermatology Life Quality Index. Written approval was obtained for its use in this study: Cardiff University (09/2015). Other factors considered in the study were obesity using the Body Mass Index, the levels of stress using the Beck Anxiety Inventory, and the presence of insomnia using the Athens Insomnia Scale. Blood draws and inflammatory markers measurements were performed for all participants. Both CRP and ESR levels were higher in the case group (ie Psoriasis and Depression and Psoriasis) compared to healthy controls. Furthermore, psoriatic patients with depression showed increased CRP and ESR levels compared to those of psoriatic patients without depression. The evaluation of both CRP and ESR and their use to detect the presence of depression in patients with psoriasis can be an important tool for their holistic treatment of theirs.

Development of a nomogram prediction model for depression in patients with systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is an inflammatory autoimmune disease with depression as one of its most common symptoms. The aim of this study is to establish a nomogram prediction model to assess the occurrence of depression in patients with SLE. Based on the Hospital Anxiety and Depression Scale cutoff of 8, 341 patients with SLE, recruited between June 2017 and December 2019, were divided into depressive and non-depressive groups. Data on socio-demographic characteristics, medical history, sociopsychological factors, and other risk factors were collected. Between-group differences in clinical characteristics were assessed with depression as the dependent variable and the variables selected by logistic multiple regression as predictors. The model was established using R language. Marital status, education, social support, coping, and anxiety predicted depression (p < 0.05). The nomogram prediction model showed that the risk rate was from 0.01 to 0.80, and the receiver operating characteristic curve analysis showed that the area under the curve was 0.891 (p < 0.001). The calibration curve can intuitively show that the probability of depression predicted by the nomogram model is consistent with the actual comparison. The designed nomogram provides a highly predictive assessment of depression in patients with SLE, facilitating more comprehensive depression evaluation in usual clinical care.

Developing a visual model for predicting depression in patients with lung cancer.

To investigate and analyse the prevalence of depression among patients with lung cancer, identify risk factors of depression, and develop a visual, non-invasive, and straightforward clinical prediction model that can be used to predict the risk probability of depression in patients with lung cancer quantitatively. Depression is one of the common concomitant symptoms of patients with lung cancer, which can increase the risk of suicide. However, the current assessment tools cannot combine multiple risk factors to predict the risk probability of depression in patients. A cross-sectional study. The clinical data from 297 patients with lung cancer in China were collected and analysed in this cross-sectional study. The clinical prediction model was constructed according to the results of the Chi-square test and the logistic regression analysis, evaluated by discrimination, calibration, and decision curve analysis, and visualised by a nomogram. This study was reported using the TRIPOD checklist. 130 patients with lung cancer had depressive symptoms with a prevalence of 43.77%. A visual prediction model was constructed based on age, disease duration, exercise, stigma, and resilience. This model showed good discrimination at an AUC of 0.842. Calibration curve analysis indicated a good agreement between experimental and predicted values, and the decision curve analysis showed a high clinical utility. The visual prediction model developed in this study has excellent performance, which can accurately predict the occurrence of depression in patients with lung cancer at an early stage and assist the medical staff in taking targeted preventative measures. The visual, non-invasive, and simple nomogram can help clinical medical staff to calculate the risk probability of depression among patients with lung cancer, formulate personalised preventive care measures for high-risk groups as soon as possible, and improve the quality of life of patients.

Blood Inflammatory Cytokines as Predictors of Depression in Patients With Glioma.

BackgroundDepression commonly develops as a comorbid disorder related to glioma, which affects the patients’ physical function and prognosis. Circulating inflammatory cytokines are potential predictors of depression in disparate cancers. However, less research has specifically investigated this aspect within the context of glioma.Study objectivesThe objective of this study was to investigate the occurrence of depression in patients with glioma and draw a comparison of the ability to predict it through diverse inflammatory cytokines.MethodsA total of 203 patients with stage I–IV glioma were enrolled in this study. Depression was evaluated according to the Hamilton Depression Scale, and the plasma inflammatory cytokines levels were simultaneously measured. We performed the receiver operating characteristic (ROC) analysis to confirm the abilities of identified inflammatory cytokines to predict depression.ResultsAmong the 203 patients with glioma, 135 (66.5%) showed obvious depressive symptoms. Proinflammatory cytokines, including interleukin (IL)-6 (area under the curve (AUC) = 0.76) and tumor necrosis factor (TNF)-α (AUC = 0.75), showed good performance in accurately predicting depression in patients with glioma. These inflammatory cytokines indicated great potential to be depression biomarkers regardless of the patients’ disparate treatment experience.ConclusionWith their relatively simple and time-saving measurement procedures, inflammatory cytokines should be seriously considered effective clinical screening and diagnostic tools, as well as potential biomarkers for depression in patients with glioma.

Incidence and Risk Factors of Post-Operative Depression in Patients Undergoing Transurethral Resection of Prostate for Benign Prostatic Hyperplasia.

BackgroundBenign prostatic hyperplasia (BPH) is a frequent-occurring disease in middle-aged and elderly men. This work is a prospective study and aims at exploring the incidence of post-operative depression and the potential risk factors of depression in a cohort of patients with BPH in China.MethodsIn this survey, 611 men who underwent transurethral resection of the prostate (TURP) were strictly selected at our institution from January 2016 to August 2019. Zung Self-rating Depression Scale was used for evaluation of depressive symptoms. Sociodemographic, clinical and other data were also collected.ResultsWe found that 152/611 (24.9%) patients suffered from different degree of depression at 6 months after TURP, including mild symptoms (20.9%) and moderate/severe symptoms (3.9%). A total of 421 (68.9%) patients developed post-TURP erectile dysfunction (ED). The occurrence of depression was closely associated with marital status, education level, cigarette smoking, alcohol consumption, severity of lower urinary tract symptoms (LUTS), duration of BPH, erectile function, and comorbidities (such as diabetes, dyslipidaemia and bladder stone). The risk factors related to the severity of depression included widowed or single marital status, frequent alcohol consumption, moderate or severe LUTS, longer duration (> 5 years) of BPH, ED, urinary continence, and comorbidities such as diabetes and bladder stone.ConclusionMany risk factors are related to the occurrence of depression in patients undergoing TURP. Widowed or single marital status, frequent alcohol consumption, moderate or severe LUTS, longer duration of BPH, ED, urinary incontinence and comorbidities such as diabetes and bladder stone are connected with the increase odds of moderate or severe depressive symptom.

Anxiety, Depression and Sleep Disturbances among Renal Disorders in Tertiary Care Center

Depression is the most general psychiatric disease in patients with Chronic Kidney Disease (CKD). Depression exposed to affect mortality in end-stage renal disease patient. The main focus of this study was to measure the occurrence of painful symptoms among CKD patients. Co-morbid depression influences harmfully on the excellence of life in Chronic Kidney Disease patients. This study was done to calculate predominance of depression inpatient on hemodialysis (HD) using Patient Health Questionnaire-9, Hamilton Rating Scale for Depression-17 and International Classification of Disease-10 classification of mental and behavioural disorders. It was a cross-sectional study conducted from December 2019 till July 2020, in Nandhyala, Kurnool district region. Informed and written consent was taken. Patients undergoing hemodialysis at the Nandhyala, Kurnool district region for more than three months duration were involved in the study. Psychiatrists monitored Hamilton Rating scale for diagnosis and categorization of depression. Psychiatrists confirmed depression based on International Classification of Disease-10 scale. SPSS version.20 was used for statistical analysis. The study was done among 300 patients. Prevalence of depression was 234 using Patient Health Questionnaire-9 (PHQ-9)and 195 using Hamilton Rating scale (HAD-17)and 153 using International Classification of Disease -10 (ICD-10). Mean depression in females using PHQ-9 was 7±4.33 and in males was 11.04±5.90, and the Median age was 47.6 years. The most common symptom was fatigue among 246. There is a high occurrence of depression in patients with Chronic Kidney Disease (CKD) stage 5 on hemodialysis compared to the general population.

Postoperative depression in patients after coronary artery bypass grafting (CABG) - a review of the literature.

&lt;b&gt;Introduction:&lt;/b&gt; Ischemic heart disease is the most common cause of death in the world. The lives of patients with vascular defects can be saved by coronary artery bypass grafting (CABG). However, it is associated with an increased risk of developing depression after surgery. &lt;br&gt;&lt;b&gt;Meterial and Methods:&lt;/b&gt; The aim of the study is to present the results of the latest research on postoperative depression after CABG, including studies describing the course of the disease, its consequences for the patient's prognosis and treatment. The publications available on the PubMed platform published after 2011 were reviewed. &lt;br&gt;&lt;b&gt;Results:&lt;/b&gt; Depression before and after CABG affects 30-40% of patients, mostly women. Established after surgery and untreated, it persists for many years. The level of anxiety in patients decreases systematically after surgery. Indicators that may correlate with the patient's postoperative depression, including cortisol, high sensitivity C-reactive protein (hsCRP) and oxidative stress biomarkers, are being investigated. The occurrence of depression in patients after CABG has a number of negative consequences. Those include: weaker response to treatment, greater chance of relapse, and increased readmission frequency and mortality. Treatment of patients with this disorder involves the use of antidepressants (most often SSRIs - selective serotonin reuptake inhibitor) and/or various types of psychotherapy with cognitive behavioral therapy (CBT) at the forefront. &lt;br&gt;&lt;b&gt;Conclusions:&lt;/b&gt; Depression following CABG decreases the quality of life and worsens patient prognosis. It is necessary to detect this condition early after surgery and to apply treatment, taking into account the cardiological disorders of the patient.

Factors Affecting Occurrence of Depression in Patients with Cervical Cancer at Dr. Moewardi Hospital Surakarta, Central Java: A Path Analysis Model

Background: Cervical cancer is in the second place among the incidence of new cases and in thethird highest death from cancer. Cancer depression and severity generally occur together with psychological problems, such as anxiety, pain and fatigue. Most studies in cancer patients have focused on morbidity or mortality more due to the risk of depression. The purpose of this study was to analyze the factors that influence depression in cervical cancer patients. Subjects and Method: A cross sectional study was conducted at Dr. Moewardi Hospital, Surakarta, Central Java, from September to October 2019. A sample of 200 cervical cancer patients was selected by simple random sampling. The dependent variable was depression. The independent variables were marital status, education, occupation, family income, peer support, family support, health personnel support, coping strategy, cancer stage, frequency of chemothe­rapy, and length of illness from diagnosis. Depression was measured by the Beck Depression Inventory-II (BDI-II) questionnaire. The other data were collected by medical record and question­naire. The data were analyzed by path analysis run on Stata 13. Results: Severe depression in cervical cancer patients was directly increased by the frequency of chemotherapy 3 times (b= 1.80; 95% CI= 0.11 to 3.49; p= 0.037), advanced stage (b= 2.50; 95% CI= 0.18 to 4.82; p= 0.035), and length of illness from diagnosis ≥11 months (b= 2.27; 95% CI= 0.57 to 3.96; p= 0.009). Severe depression was directly decreased by high coping strategy (b= -6.33; 95% CI= -8.68 to -3.98; p<0.001). Severe depression was indirectly affected by peer support, family support, support of health personnel, family income, occupation, education, and marital status. Conclusion: Severe depression in cervical cancer patients is directly increased by the frequency of chemotherapy 3 times, advanced stage, and length of illness from diagnosis ≥11 months. Severe depression is directly decreased by high coping strategy. Severe depression is indirectly affected by peer support, family support, support of health personnel, family income, occupation, education, and marital status.

Depression among patients undergoing maintenance hemodialysis at a tertiary care center in Kathmandu, Nepal

Introductions:Patients with chronic kidney disease have a high burden of somatic symptoms which may be due to depression. This study analyses occurrence of depression in patients with chronic kidney disease (CKD) undergoing hemodialysis (HD) at a tertiary care center in Kathmandu, Nepal.&#x0D; Methods: This is a retrospective study done at Patan Hospital, a tertiary care teaching hospital of Patan Academy of Health sciences, Lalitpur, Nepal. Translated in Nepali language and validated Beck Depression Inventory (BDI) was used. A cut-off of 16/17 was used to define depression. &#x0D; Results: Altogether 56 patients were included, mean age 54.375±17.87 years, time on HD 25.06±21.58 months, BDI score 19.18±10.16. The prevalence of depression was 51.8%. There was no significant differences of BDI score and rate of depression in genders, housing status, education level, alcohol intake, presence of co-morbidity and shift of HD. However, there was a significant association of BDI score and the employment status, p=0.026 and the affordability of erythropoiesis stimulating agent, p=0.033.&#x0D; Conclusions: Depression was common in patients undergoing hemodialysis treatment and the rate of depression was significantly lower in the patients who were employed and used of erythropoiesis stimulating agent.

Palliative care in heart failure : Ameta-analysis of randomized controlled trials.

Palliative care can play an important role in the management of heart failure. We conducted asystematic review and meta-analysis to compare the efficacy and safety of palliative care in patients with heart failure. PubMed, Embase, Web of Science, EBSCO, and the Cochrane Library databases were systematically searched. Randomized controlled trials (RCTs) on the impact of palliative care on heart failure were included. Two investigators independently searched the articles, extracted data, and assessed the quality of included studies. The primary outcome was mortality. Seven RCTs were included in the meta-analysis. Compared with usual care for heart failure, palliative care was associated with asignificantly increased quality of life (standardized mean difference = 1.46; 95% confidence interval [CI] = 0.12 to 2.79; p = 0.03) and reduced depression scores (standardized mean difference = -0.62; 95% CI = -0.99 to -0.25; p = 0.03), but demonstrated no impact on mortality (risk ratio [RR] = 1.28; 95% CI = 0.86 to 1.92; p = 0.22) and rehospitalization (RR = 0.84; 95% CI = 0.66 to 1.07; p = 0.16). Palliative care can improve the quality of life and reduce the occurrence of depression in patients with heart failure.

Relationships of circular RNA with diabetes and depression

Type 2 diabetes mellitus (T2DM) is closely related to depression; however, the exact molecular mechnisms of this association are unknown. Here, we investigated whether circular RNAs (circRNAs) in the blood are related to the occurrence of depression in patients with T2DM. Fourteen patients with T2DM and depressive symptoms, as assessed by the Self-Rating Depression Scale, were included in this study. Cutoff points of 44 (total coarse points) and 55 (standard score) were used to define depression. The Patient Health Questionnaire 9 was used for common mental disorders, and a score of 5 or more the cutoff for depression. Microarray assays and quantitative real-time reverse transcription polymerase chain reaction showed that 183 hsa-circRNAs were significantly upregulated, whereas 64 were downregulated in the T2DM with depression group (p < 0.05) compared with that in the T2DM group. Differentially expressed hsa-circRNAs could interact with microRNAs to target mRNA expression. KEGG pathway analysis predicted that upregulation of hsa-circRNA_003251, hsa-circRNA_015115, hsa-circRNA_100918, and hsa_circRNA_001520 may participate in the thyroid hormone, Wnt, ErbB, and mitogen-activated protein kinase signalling pathways. We speculate that differentially expressed hsa-circRNAs could help us to clarify the pathogenesis of depression in patients with T2DM and could represent novel molecular targets for clinical diagnosis and therapy.

Statin Function as an Anti-inflammation Therapy for Depression in Patients With Coronary Artery Disease by Downregulating Interleukin-1β.

It is well known that inflammation contributes to the development of coronary artery disease (CAD) and depressive symptoms. Previous studies have shown that long-term application of statin reduces the occurrence of depression in patients with CAD. However, the mechanism remains unclear. We hypothesized that inflammation contributes to depression in patients with CAD and statin function as an anti-inflammation therapy for those depressive patients. Patients with confirmed CAD hospitalized in the Department of Cardiology of Tongji Hospital in Shanghai, China, were enrolled. Depression was identified as none (ND), mild (MiD), moderate (MoD), or severe (SD) on the basis of scores of the patient health questionnaire with 9 items. Inflammatory factors in peripheral blood were measured using a chemiluminescence immunoassay and Bio-plex. Luciferase expression level was detected using the Dual-Luciferase Reporter Assay System for IL-1β or NF-κB expression by transfection in human umbilical vein endothelial cells, and patient serum was added. Data obtained from 217 patients with CAD were analyzed. The IL-1β level of CAD with SD was 14.70, which was significantly higher than that of CAD with ND 7.52, MiD 7.73, or MoD 8.63. Luciferase reporter gene analysis showed that IL-1β or NF-κB expression level was upregulated by the serum of CAD and depression patients. After the addition of atorvastatin, IL-1β or NF-κB luciferase reporter expression level decreased. It suggested that depression in patients with CAD is associated with inflammation. Statin may function as an anti-inflammation therapy for depression in patients with CAD by downregulation of IL-1β.

Frequencies of apolipoprotein E alleles in depressed patients undergoing hemodialysis – a case-control study

Objective: To explore the relation between the frequencies of apolipoprotein E (ApoE) alleles and the occurrence of depression in patients undergoing hemodialysis in a Chinese population. Methods: We examined the ApoE alleles in a sample of 288 subjects: 72 patients with depression under hemodialysis, 74 patients without depression under hemodialysis, 75 patients with depression under nondialytic treatment and 67 patients without depression under nondialytic treatment. The depression state was assessed using the Center for Epidemiological Studies Depression (CES-D) scale. Associations between the occurrence of depression and the frequencies of ApoE alleles were examined using multinomial logistic regression models with adjustment of relevant covariates. Information about sociodemographics, clinical data, vascular risk factors and cognitive function was also collected and evaluated. Results: The frequencies of ApoE-ɛ2 were significantly different between depressed and non-depressed patients irrespective of dialysis (p < 0.05), but no significant difference was found in the frequencies of ApoE-ɛ4 (p > 0.05). Serum ApoE levels were significantly different between depressed and non-depressed patients in the whole sample (p < 0.05). Multinomial logistic regression models showed significant association between the frequency of ApoE-ɛ2 and the occurrence of depression in the Chinese population after control of relevant covariates, including age, sex, educational level, history of smoking and drinking, vascular risk factors and cognitive function. Conclusions: No association between the frequency of ApoE-ɛ4 and the occurrence of depression was found in patients undergoing hemodialysis. Further research is needed to find out if ApoE-ɛ2 acts as a protective factor in Chinese dialysis population since it might decrease the prevalence of depression and delay the onset age.

Quality of life and occurrence of depression under chemotherapy in patients suffering from lung carcinoma.

In Poland, lung carcinoma is the most frequent malignant neoplasm in men and the third most frequent in women. The neoplastic disease causes enormous psychic stress and may lead to depressive reactions. The purpose of this research was to assess the quality of life and the occurrence of depression in patients suffering from lung neoplasms and undergoing chemotherapy. The research covered 102 patients (test group TG) with lung carcinoma and undergoing chemotherapy. In the research, standardised questionnaires: EORTC-QLQ-C30, Beck Depression Inventory and a matrix developed by the researcher were applied. The control group (CG) consisted of 60 healthy people who were examined by the Beck Depression Inventory. A highly statistically significant dependency was found (p<0.01) between the general quality of life and the occurrence of depression. 51.5% of those examined with a very low level of general quality of life had the symptoms of severe depression. Those examined who had a very high level of general quality of life did not have features of severe depression. A statistically significant dependency (p<0.01) was ascertained between the occurrence of depression and the health condition of those examined. Depression symptoms occur more frequently and with greater intensity in patients suffering from lung neoplasm, compared to the group of healthy people (p<0.01). A statistically significant connection between marital status, place of residence, and assessment of quality of life was found out (p<0.05).
