Bioactive compounds of the Mediterranean diet and prostate cancer

Abstract

Objective: The purpose of this review is to examine the evidence on the effects of bioactive constituents of the Mediterranean diet (MeDi) on prostate cancer (PCa) risk.

Methods: The search for articles came from extensive research in the following databases: PubMed, Scopus, and Web of Science. We used the search terms “Mediterranean diet,” “lycopene,” “vitamin E,” “vitamin C,” “Selenium,” “resveratrol,” “prostate cancer,” and combinations, such as “lycopene and prostate cancer” or “resveratrol and prostate cancer.”

Results: Numerous studies investigating the effect of various dietary nutrients on PCa have suggested that selenium is probably the most promising. Several studies reported reduced PCa risk associated with vitamin C and E intake, while other studies reported no association. Lycopene inhibits cell proliferation and inducts apoptosis, thus protecting against cancer. Also, it has been found in various in vivo and in vitro studies that resveratrol, inhibits PCa development.

Conclusions: The high content of bioactive phytochemicals in the MeDi is of particular interest in the prevention of PCa. Further large-scale studies are required to clarify the effect of MeDi bioactive compounds on prostate health, in order to establish the role of this diet in the prevention of PCa.     

The influence of nutritional factors on prostate cancer incidence and aggressiveness

There is an increasing evidence for a link between nutrition, lifestyle and prostate cancer (PCa) development and/or progression of disease. The objective of this study was to examine the association between dietary factors and PCa incidence and aggressiveness in a case-control study. After the analysis of the anatomic pathology, subjects were classified in patients with PCa (n?=?157) and controls (n?=?158). Clinical data including Gleason score, PSA values and biopsy results, were compiled. Frequencies of food consumption and sociodemographic data were also obtained. The results showed that physical activity was significantly higher in control (p?p?=?.041) and fish (p?=?.041) intakes. Moreover, there was a significant reduction in risk (p?=?.029) in cases with a higher fruits and vegetables intakes. A decreased risk of aggressive PCa was associated with fruits, vegetables, legumes and fish intakes. However, these relationships were not statistically significant when data were adjusted for covariates. In conclusion, this study found an inverse association between PCa risk and the intake of fruits and vegetables, fish and nuts. The results suggested that a diet with higher intakes of these foods as Mediterranean diet may lower the risk of PCa in the studied population. As dietary factors are modifiable, identifying food groups or dietary patterns that modulate the risk of PCa and its aggressiveness can offer effective and practical strategies for its primary prevention.     

Association between dietary phytoestrogens intakes and prostate cancer risk in Sicily

Objective: In this study we aimed to investigate the association between dietary phytoestrogen consumption and prostate cancer in a sample of southern Italian individuals.

Methods: A population-based case-control study on the association between prostate cancer and dietary factors was conducted from January 2015 to December 2016 in a single institution of the municipality of Catania, southern Italy (Registration number: 41/2015). A total of 118 histopathological-verified prostate cancer (PCa) cases and a total of 222 controls were collected. Dietary data was collected by using two food frequency questionnaires.

Results: Patients with PCa consumed significantly higher levels of phytoestrogens. Multivariate logistic regression showed that lignans (Q[quartile]4 vs. Q1, OR [odds ratio]?=?4.72; p?p?p?p?p?p?p?Conclusion: We found of an inverse association between dietary isoflavone intake and PCa, while a positive association was found with lignans intake.     

The effect of 6 months of androgen deprivation therapy on muscle and fat mass in older men with localized prostate cancer

Objective.?To evaluate body composition changes, specifically skeletal muscle mass, in men receiving androgen deprivation with luteinizing-hormone releasing hormone-agonist (LHRH-A) for prostate cancer (PCa) in comparison with healthy controls.

Design.?Retrospective analysis of body composition changes in men with prostate cancer receiving LHRH-A therapy from 2 clinical trials compared to men without prostate cancer serving as a placebo-control in another clinical trial.

Setting.?Clinical Research Center in Connecticut.

Participants.?Thirty men (> 60 years) receiving 6 months of LHRH-A therapy for PCa were compared to a healthy group of 25 men without PCa.

Measurements.?Appendicular skeletal muscle/height² (ASM/ht²), lean and fat mass were assessed by dual energy x-ray absorptiometry. Total testosterone levels were assessed by enzyme immunoassay.

Results.?At baseline, 12/30 (40%) of the treatment group and 7/25 (28%) of the control group (p = 0.11) met criteria for sarcopenia. There were no differences between control groups in ASM/ht² or lean mass. The LHRH-A group had a higher percent body fat than the control group, 29.8 ± 6.3 versus 26.3 ± 4.6 (p = 0.02). ASM/ht² and lean mass decreased in the LHRH-A group from 7.5 ± 0.9 kg to 7.3 ± 0.9 kg (?2.3% ± 0.03; p ? 0.001) and 53.5 ± 5.4 kg to 52.3 ± 5.3 kg (?2.1% ± 0.03; p ? 0.001), respectively. There was no muscle loss in the control group. At 6 months, the LHRH-A group had increased percent body fat from 29.8 ± 6.4 to 32.2 ± 5.8 (9.5% ± 0.13; p ? 0.001), whereas the control group had decreased in percent body fat from 26.6 ± 4.6 to 25.3 ± 5.0 (?3.8% ± 0.08; p = 0.02).

Conclusions.?Men undergoing LHRH-A treatment for PCa decreased appendicular skeletal muscle and lean tissue and increased body fat within 6 months of initiation of therapy. Lifestyle changes or medical interventions to minimize the effects of androgen deprivation therapy for PCa deserve investigation.     

Body mass index and functional status in community dwelling older Turkish males

Abstract

Objectives: To assess sex hormones in men with obesity and prostate cancer (PCa) and to study association between androgens and the pathogenesis biology of PCa in vitro.

Subjects and methods: One hundred and eighty-one men older than 45?years selected from of a population attending to Urology departments screening for PCa, (78 participants without PCa and 103 patients with PCa). All participants were assessed for body mass index (BMI), age, Gleason score, and PSA. Endocrine profile was determined for LH, total testosterone (TT), 17β-estradiol (E2), prolactin and leptin. Biochemical profile (HbA1c, triacylglycerols and lipoproteins) was also determined. In vitro experiments were also performed, involving the study of 5α-dihydrotestosterone (DHT) and E2 in the presence of adipocyte-conditioned medium (aCM).

Results: All variables were continuous and described a Gaussian distribution unless mentioned. To determine the relation of aggressiveness, variable were transformed into categories. Thus, PCa aggressiveness is associated with the increase of age and BMI (p?<?.0001) but with is decreased with TT and E2 (p?<?.05). Moreover, adipocyte-secreted molecules increase aggressiveness of PCa cells in vitro. Lastly, DTH but not E2 enables invasiveness in vitro.

Conclusions: It was observed a coexistence of hormone axis profile alteration with sex hormones and BMI in PCa patients, in accordance with the new perspective of PCa pathogenesis.     

The effect of testosterone treatment on prostate histology and apoptosis in men with late-onset hypogonadism

Objectives: To investigate the effect of testosterone replacement therapy (TRT) on prostate histology and apoptosis in men with late-onset hypogonadism (LOH).

Methods: The study included 25 men, having LOH with prostate-specific antigen (PSA) level of 4?ng/ml or less. All patients underwent transrectal ultrasound guided prostate biopsy at baseline, and received testosterone undecanoate treatment for 1 year. Prostate biopsy was repeated at the end of 1 year of testosterone therapy. In addition to clinical and biochemical parameters, prostate histology and apoptotic index (AI) were compared before and after the TRT.

Results: The mean serum total testosterone significantly increased from 178.04?±?51.92 to 496.28?±?103.73?ng/dl (p?=?0.001). No significant differences were observed in serum total and free PSA level, prostate volume and maximal urinary flow rate. There were also no significant differences in AI, stroma/epithelial cells ratio, Ki-67 positive cells and atrophy score of prostate tissue before and after the TRT.

Conclusions: This study demonstrated that TRT did not affect serum PSA level, prostate volume and maximal urinary flow rate. This study also suggests that TRT does not cause the risk for prostate cancer development, because of no significant differences in prostate histology after TRT.     

The impact of atherosclerosis on lower urinary tract function

Abstract

Objective: The current study was carried out to investigate the impact of atherosclerosis on lower urinary tract function in the male patients with lower urinary tract symptoms (LUTS).

Patients and methods: This prospective study evaluated 110 male patients aged 55–75 years who were presented with LUTS. All patients underwent general and local investigations. The atherosclerosis was assessed by ultrasound examination of the carotid artery. Patients then were divided into two groups: non-atherosclerosis group (Group 1) and atherosclerosis group (Group 2). The two groups were compared regarding voiding and storage parameters.

Results: Mean patient age were 67.9?±?5.9 years. The average age and number of Group 1 was 65.7?±?4.3, n?=?51. The average age and number of Group 2 was 68.7?±?5.3, n?=?59. There were no significant differences in age, prostate volume, blood pressure, International Prostate Symptom Score, Voiding symptom score and Storage symptom score between the two groups. Blood serum triglycerides were significantly lower in Group 1 than Group 2 while HDL cholesterol were significantly higher in Group 1 than Group 2 0.97?±?0.5 and 1.43?±?0.2?mmol/L, versus 1.46?±?0.7 and 1.28?±?0.3?mmol/L, respectively. Qmax denotes significant decrease in Group 2 compared with Group 1 12.5?±?6.3 versus 17.6?±?6.5, respectively (p?<?0.01). While in post-voiding residual urine, there was a significant increase in Group 2 compared with Group 1 82.2?±?15.4 versus 51.4?±?12.7, respectively (p?<?0.01). Daytime voided urine denotes a significant decrease in Group 2 176?±?48, compared with Group 1 221.2?±?79 (p?<?0.01). Daytime frequency and nocturia, were significantly higher in Group 2, compared with Group 1 8.90?±?2.8 versus 7.16?±?3.11, respectively, and 3.1?±?1.2 versus 1.92?±?1.12, respectively (p?<?0.05).

Conclusion: The atherosclerosis disease play a significant role in the impairments of both voiding and storage function in male patients with LUTS irrelevant to the age.     

Physical activity is inversely related to drug consumption in elderly patients with cardiovascular events

Elderly patients with cardiovascular events are characterized by high drug consumptions. Whether high drug consumptions are related to physical activity is not known. In order to examine whether physical activity is related to drug consumption in the elderly, patients older than 65 years (n?=?250) with a recent cardiovascular event were studied. Physical activity was analyzed according to the Physical Activity Scale for the Elderly (PASE) score and related to drug consumption. PASE score was 72.4?±?45.0 and drug consumption was 8.3?±?2.2. Elderly patients with greater comorbidity took more drugs (8.7?±?2.1) and are less active (PASE?=?64.4?±?50.6) than patients with Cumulative Illness Rating Scale severity score higher than 1.8 than those with a score lower than 1.8 (76.3?±?41.4, p?<?0.05, and 8.0?±?2.0, p?=?0.006, respectively). Multivariate analysis correlation confirmed that PASE score is negatively associated with drug consumption (β?=??0.149, p?=?0.031), independently of several variables including comorbidity. Thus, physical activity is inversely related to drug consumption in elderly patients with cardiovascular events. This inverse relationship may be attributable to the high degree of comorbidity observed in elderly patients in whom poor level of physical activity and high drug consumption are predominant.     

Leaving Home in Europe: The Role of Parents’ and Children’s Incomes

This paper examines the role of parents’ and children’s incomes in the ‘leaving home’ decisions of young adults in Europe. Using the ECHP data on 11 European countries, results from random and fixed-effects models suggest that the leaving home decision is positively related to the child’s income. The effect of parents’ income is less clear and of lower magnitude. These patterns are broadly similar among European countries, in spite of significant differences in the institutional contexts.     

Administration of daily 5 mg tadalafil improves endothelial function in patients with benign prostatic hyperplasia

Introduction: Tadalafil is a promising phosphodiesterase (PDE) 5 inhibitor prescribed for erectile dysfunction (ED). Daily low dose (5?mg) of tadalafil has also been used for the treatment of male lower urinary tract symptoms (LUTS) associated with benign prostate hyperplasia (BPH). PDE5 inhibitors induce relaxation of smooth muscle cells in the urethra, prostate, bladder neck, and blood vessels. The aim of this study was to investigate the efficacy of tadalafil on vessels endothelial function, in patients with male LUTS symptoms associated with BPH.

Methods: The Institutional Review Board (IRB) approved this clinical study and informed consents had been obtained from 81 BPH patients.

The following male LUTS parameters: international prostate symptom score (IPSS), overactive bladder symptom score (OABSS), voiding volume, max and mean voiding flow on voiding flowmetry examination and post-voiding residual urine (RU) were compared at 0, 1, 3, 6, and 12 months after a daily dose of 5?mg tadalafil.

In addition, erectile function was evaluated by the sexual health inventory for men (SHIM) score and vessels endothelial function and peripheral neuropathy were assessed by the brachial-ankle pulse wave velocity (baPWV), ankle brachial index (ABI), and vibration perception threshold (VPT) at 0, 3, 6, and 12 months after treatment.

Results: The mean age of 81 patients was 66.4?±?11.4 years old. Their prostate size was 30.2?±?22.1?ml.

Male LUTS parameters including IPSS, OABSS, and RU showed significant improvement from 1 to 12 months after tadalafil administration. Max and mean voiding flow was significantly increased at 6 months after tadalafil treatment.

The SHIM score showed significant improvement after 3 months. Whilst, the results of baPWV also showed significant improvement from 3 to 12 months. ABI was also significantly improved at 6 months. However, there was no change in the VPT at any time point.

Conclusions: Tadalafil is effective for both male LUTS and ED. It is also shown that tadalafil improves baPWV, which we can conclude that higher vessels elasticity has been obtained. This major finding of this study shows that tadalafil has the potency to improve vessels endothelial dysfunction in patients with BPH.     

Is there a protective role of testosterone against high-grade prostate cancer? Incidence and severity of prostate cancer in 553 patients who underwent prostate biopsy: a prospective data register

This study investigated the role of testosterone replacement therapy (TRT) in prostate safety and cancer progression. A cohort of 553 patients, 42 treated and 162 untreated hypogonadal men, and 349 eugonadal men were included. Pathological analysis of prostate biopsies examining the incidence and severity of PCa revealed that: 16.7% of treated hypogonadal men had a positive biopsy, a Gleason score of ≤6 in 71.4% and >6 in 28.6% of men, a predominant score of 3 and tumour staging of II in 85.7% men; 51.9% of untreated hypogonadal men had a positive biopsy, a Gleason score of ≤6 in 40.5% and >6 in 59.5% men, a predominant score of 3 (77.4%) and tumour staging of II (41.7%) or III (40.5%); 37.8% of eugonadal men had a positive biopsy, a Gleason score of ≤6 in 42.4% and >6 in 57.6% of men, a predominant score of 3 (82.6%) and tumour staging of II (44.7%) or III (47.7%). The incidence of positive prostate biopsies was lowest in hypogonadal men receiving TRT, with significantly lower severity of PCa in terms of staging and grading in the same group. These results suggest that TRT might have a protective effect against high-grade PCa.     

Low skeletal muscle mass index is associated with function and nutritional status in residents in a Turkish nursing home

Introduction: To determine the prevalence of low muscle mass (LMM) and the relationship between LMM with functional and nutritional status as defined using the LMM evaluation method of European Working Group on Sarcopenia in Older People (EWGSOP) criteria among male residents in a nursing home.

Methods: Male residents aged?>60 years of a nursing home located in Turkey were included in our study. Their body mass index (BMI) kg/m², skeletal muscle mass (SMM-kg) and skeletal muscle mass index (SMMI-kg/m²) were calculated. The participants were regarded as having low SMMI if they had SMMI?<9.2?kg/m² according to our population specific cut-off point. Functional status was evaluated with Katz activities of daily living (ADL) and Lawton Instrumental Activities of Daily Living (IADL). Nutritional assessment was performed using the Mini Nutritional Assessment (MNA). The number of drugs taken and chronic diseases were recorded.

Results: One hundred fifty-seven male residents were enrolled into the study. Their mean age was 73.1?±?6.7 years with mean ADL score of 8.9?±?2.0 and IADL score of 8.7?±?4.6. One hundred twelve (71%) residents were aged?>70 years. Thirty-five men (23%) had low SMMI in group aged?>60 years, and twenty-eight subjects (25%) in the group aged?>70 years. MNA scores were significantly lower in residents with low SMMI compared with having normal SMMI (17.1?±?3.4 versus 19.6?±?2.5, p?=?0.005). BMI was significantly lower in the residents with low SMMI compared with normal SMMI (19.6?±?2.7 versus 27.1?±?4.1, p70 years (8.1?±?2.6 versus 9.1?±?1.6, p?=?0.014). In regression analyses, the only factor associated with better functional status was the lower age (p?=?0.04) while the only factor associated with better nutrition was higher SMMI (p?=?0.01).

Conclusions: Low SMMI detected by LMM evaluation method of EWGSOP criteria is prevalent among male nursing home residents. There is association of low SMMI with nutritional status and probably with functional status within the nursing home setting using the EWGSOP criteria with Turkish normative reference cut-off value.     

Living status in patients over 85 years of age after TUVRP

Abstract

Introduction: To evaluate surgical risk and post-operative quality of living status in patients over 85 years of age after transurethral vaporization resection of the prostate (TUVRP).

Methods: Sixty patients over 85 years of age underwent TUVRP were compared with 228 patients less than the age of 80 years. Group A was 60 patients greater than 85 years of age, Group B was 137 patients from 71 to 79 years of age, and Group C was 91 patients from 60 to 70 years of age.

Results: In Group A, pre-operative ASA grade was higher than the other two groups, compared with Group C, p?<?0.01. Operating time was 40.03?±?18.90?min, compared in the three groups, p?>?0.05. Follow-up was obtained in 49 (81.67%) patients; of them 10 patients were deaths with a survival time of 22.90?±?11.14 months. In the 39 survivors, post-operative IPSS score was 11.17?±?6.9, compared with Group B, p?>?0.05 and Group C, p?<?0.01. Quality of Life (QOL) index was 1.11?±?0.80, compared with Group B, p?<?0.001 and Group C, p?<?0.01. Barthel Index score in 16 patients was >60 and the score was 82.81?±?8.56 pre-operatively. The patients with >60 were increased to 19 cases and the score was improved to 90.93?±?7.58 (p?<?0.001) in follow-up.

Conclusion: Surgical risk in patients over 85 years of age was higher than patients less than the age of 80 years. A safety TUVRP could improve their voiding function and activities of daily living.     

Association of testicular p63 expression and spermatogenesis in androgen receptor knockout (ARKO) mice

Objective.?To study changes of testicular p63 expression and its effect on spermatogenic function in seminiferous tubules in androgen receptor knockout (ARKO) mice.

Methods.?A total of 28 ARKO mice (ARKO group) screened by Cre-lox and 28 male Wistar mice without ARKO (controlled group) were enrolled in our study. Route pathology was performed and p63 examination was detected by immunohistochemistry in testes. Linear correlations were used to explore potential associations between p63 protein expression and spermatogenic function (TMS score).

Results.?In ARKO group, inner diameter of seminiferous tubules was decreased (62?±?1.3?μm vs. 91?±?1.2?μm), thickness of the basal membrane of the tubules (4?±?0.3?μm vs. 2.7?±?0.5?μm), cellular population within tubules was reduced (2?±?0.4 vs. 4?±?0.1 layers), degree of spermatogenesis within the tubules turned to disturbance (3?±?1.0 vs. 5?±?0.1), Testicular Makler score was lower than controlled group (7?±?0.2 vs.15?±?0.3), they had significant differences (p <0.01). P63 expressed significantly lower in ARKO group than that in Wistar group, and was limited at stages from spermatocyte to round spermatid. (Percentage of positive cells ? 68.1?±?3.7 vs. 81.7?±?5.1, p?<0.001). The HSCORE yielded similar results (HSCORE 3.7?±?0.3 vs. 2.0?±?0.2, p?<0.001). p63 protein expression was significantly positively correlated with spermatogenic function (r?=?0.87, p?<0.01).

Conclusions.?p63 developed important effect on spermatogenesis and the regulatory effect of p63 on spermatogenesis mainly occurred in the early stage of spermiogenesis in testis.     

The effect of testosterone therapy on lower urinary tract symptoms/bladder and sexual functions in men with symptomatic late-onset hypogonadism

Objective.?To prospectively investigate the effect of testosterone therapy on lower urinary tract symptoms (LUTS)/bladder and sexual functions in men with symptomatic late-onset hypogonadism (SLOH).

Methods.?The study included 25 men (age range 38 to 73 years) presented with sexual dysfunction, having SLOH, at a single university hospital. All men received testosterone replacement therapy with transdermal testosterone 50–100 mg gel per day for one year. Urodynamic studies with pressure-flow analysis, measurement of prostate volume, prostate specific antigen (PSA) and free PSA level, International Prostate Symptom Score (IPSS), Aging Male Symptom (AMS) scale and International Index of Erectile Function (IIEF-5) score were recorded in all men before and after one year of the treatment.

Results.?The mean AMS score significantly decreased from 40.4 ± 7.3 to 28.8 ± 5.31 (p = 0.001), and mean IIEF-5 score significantly increased from 8.84 ± 3.76 to 14.36 ± 3.62 (p = 0.001). The mean maximal bladder capacity and compliance significantly increased (p = 0.007 and p = 0.032, respectively), and mean detrusor pressure at Qmax significantly decreased from pre-treatment to post-treatment (p = 0.017).

Conclusion.?This study suggests that in addition to improvement in sexual functions, testosterone therapy may also improve LUTS/bladder functions by increasing bladder capacity and compliance and decreasing detrusor pressure at maximal flow in men with SLOH.     

Folate: a possible role in erectile dysfunction?

A growing body of evidence suggests a role for homocysteine (Hcys) and folate (FA) in erectile function (EF): Hcys appears to impair EF affecting endothelium via several mechanism whereas the role of FA remains to be elucidated, besides decreasing Hcys. To assess correlation between erectile dysfunction (ED) and serum levels of FA, Hcys, and B12, we enrolled 31 patients affected by ED (Group A; age 52.83?±?11.89 years) and 31 healthy adults (Group B; age 49.14?±?13.63 years). Fasting blood samples were taken for each subject. ED was assessed by the International Index of Erectile Function-5 (IIEF-5). IIEF-5 mean score was significantly lower in Group A than in Group B (10.71?±?4.24 versus 23.32?±?1.33, p?p?p?相似文献   

Older age and a higher EHRA score allow higher levels of frailty syndrome to be predicted in patients with atrial fibrillation

Background: There is no research that evaluates the relationship between the severity of the symptoms of atrial fibrillation (AF), the presence of frailty syndrome and acceptance of the illness.

Methods: The study included 132 patients aged 72.7?±?6.73 with diagnosed AF. The severity of the symptoms of AF was determined according to European Heart Rhythm Association (EHRA) guidelines, frailty syndrome was assessed using the Tilburg frailty indicator (TFI) and the acceptance of the illness was assessed using the acceptance of illness scale (AIS). A standard statistical comparison and multiple regression analysis using the stepwise method were performed.

Results: In patients with AF, frailty was 5.31?±?2.69 (TFI). Frailty syndrome was diagnosed in 59.8% of the AF patients who had a score of 7.17?±?1.72. A higher level of EHRA score was connected with a smaller degree of the acceptance of the illness p?=?0.0000. The multiple regression model indicated that age (p?=?0.0009) and the severity of the symptoms (p?=?0.0001) are important predictors of frailty syndrome.

Conclusions: There is a relationship between the presence of frailty syndrome and the intensity of the symptoms and the acceptance of AF. Age and the EHRA score permitted higher levels of frailty syndrome to be predicted.     

The effect of student residence on food choice

This study assessed the effect of student residence on food choices and dietary practices of students enrolled in an undergraduate nutrition class at Washington State University. We compared food consumption patterns of students living on campus, off campus, and in Greek housing. We also identified differences between men and women in food consumption and dietary practices. The results suggested that students' residence and sex may influence food choice and dietary practices. Significant differences in food choice related to students' residence were found for 8 of the 27 variables included on a food frequency list. Differences in the consumption of fresh fruits and vegetables, beer, fish, unsweetened cereal, white bread, and cookies were identified. In addition, students who lived in Greek housing were found to skip meals less frequently than other students, and men were found to consume significantly more beer, sugar-sweetened soft drinks, meat, and white bread than women students. Men were also more accurate in their perception of their body weight.     

Is caring for older parents detrimental to women’s mental health? The role of the European North–South gradient

In the last decades, both the lengthening of life expectancy and an accentuated decline in birth rates have reduced the consistency of the younger generational cohorts. Due to an ageing population, the burden of caregiving is expected to intensify in the next quarter of the century in Europe, especially for mature women. This paper investigates the impact of the provision of constant care for older parents on the mental health of adult daughters, between the ages of 50 and 75, living in different European countries. Data is drawn from the Survey of Health, Ageing and Retirement in Europe. Information on mental health status is provided by Euro-D depression scale, a measure of depression standardized across European countries. We focus on differences in the effects according to the North–South gradient: we test whether the relationship between informal caregiving and mental health differs across European macro-regions. Our results, robust under different specifications of the propensity score model, reveal a clear North–South gradient: the provision of informal care has a negative and significant impact on daughters’ mental health in the Mediterranean countries only, where the amount of resources allocated to the Long Term Care is minimal and the local system of health and social services for the elderly lacks the necessary structures to meet the increasing demand for eldercare.
