Objective assessment of alcohol consumption in early pregnancy using phosphatidylethanol: a cross-sectional study.

BMC Pregnancy Childbirth 2021 Apr 30;21(1):342. Epub 2021 Apr 30.

Department of Hospital Pharmacy, Erasmus MC, University Medical Center Rotterdam, Wytemaweg 80, 3015 CN, Rotterdam, the Netherlands.

Background: Alcohol consumption during pregnancy is associated with major birth defects and developmental disabilities. Questionnaires concerning alcohol consumption during pregnancy underestimate alcohol use while the use of a reliable and objective biomarker for alcohol consumption enables more accurate screening. Phosphatidylethanol can detect low levels of alcohol consumption in the previous two weeks. In this study we aimed to biochemically assess the prevalence of alcohol consumption during early pregnancy using phosphatidylethanol in blood and compare this with self-reported alcohol consumption.

Methods: To evaluate biochemically assessed prevalence of alcohol consumption during early pregnancy using phosphatidylethanol levels, we conducted a prospective, cross-sectional, single center study in the largest tertiary hospital of the Netherlands. All adult pregnant women who were under the care of the obstetric department of the Erasmus MC and who underwent routine blood testing at a gestational age of less than 15 weeks were eligible. No specified informed consent was needed.

Results: The study was conducted between September 2016 and October 2017. In total, we received 1,002 residual samples of 992 women. After applying in- and exclusion criteria we analyzed 684 samples. Mean gestational age of all included women was 10.3 weeks (SD 1.9). Of these women, 36 (5.3 %) tested positive for phosphatidylethanol, indicating alcohol consumption in the previous two weeks. Of women with a positive phosphatidylethanol test, 89 % (n = 32) did not express alcohol consumption to their obstetric care provider.

Conclusions: One in nineteen women consumed alcohol during early pregnancy with a high percentage not reporting this use to their obstetric care provider. Questioning alcohol consumption by an obstetric care provider did not successfully identify (hazardous) alcohol consumption. Routine screening with phosphatidylethanol in maternal blood can be of added value to identify women who consume alcohol during pregnancy.

Prognostic factors for the feasibility of chemotherapy and the Geriatric Prognostic Index (GPI) as risk profile for mortality before chemotherapy in the elderly.

Acta Oncol 2016 14;55(1):15-23. Epub 2015 Aug 14.

h Department of Psychiatry , Leiden University Medical Center , Leiden , The Netherlands.

Background: Comprehensive geriatric assessment (CGA) is a multidimensional method to detect frailty in elderly patients. Time saving could be accomplished by identifying those individual items that classify elderly cancer patients at risk for feasibility of chemotherapy and for mortality.

Material And Methods: Patients older than 70 years of age were assessed before the first chemotherapy administration. GA consisted of the Mini Nutritional Assessment (MNA), Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE), Groningen Frailty Indicator (GFI) and Mini Mental State Examination (MMSE). Predictive individual items for feasibility of chemotherapy and mortality were entered in the multivariable logistic regression and Cox-regression models, and a three-item sum scale was constructed: the Geriatric Prognostic Index (GPI).

Results: The 494 patients had a median age of 75 years (range 70-92 years). The majority of the patients had malignancies of the digestive tract (41.7%) followed by hematological tumors (22.3%). Three items of the MNA ('psychological distress or acute disease in the past three months', 'neuropsychological problems' and 'using > 3 prescript drugs') independently predicted for feasibility of chemotherapy. Two items of the MNA and one of the GFI ('declining food intake in past 3 months', 'using > 3 prescript drugs', and 'dependence in shopping') independently predicted for mortality. In comparison with patients without any positive item on the three-item GPI, patients with one, two or three positive items had hazard ratios (HRs) of 1.58, 2.32, and 5.58, respectively (all p < 0.001).

Conclusions: With only three items of the MNA, feasibility of chemotherapy can be predicted. The three-item GPI may help to identify elderly cancer patients at elevated risk for mortality.

Prognostic significance of geriatric assessment in combination with laboratory parameters in elderly patients with aggressive non-Hodgkin lymphoma.

Leuk Lymphoma 2015 Apr 19;56(4):927-35. Epub 2015 Feb 19.

Institute of Mental Health , Bouman GGZ Rotterdam , The Netherlands.

The age-adjusted International Prognostic Index (IPI) is an important prognostic factor for patients with non-Hodgkin lymphoma (NHL). We investigated whether a geriatric assessment (GA) is of additional prognostic value in NHL. In this prospective cohort study of 44 patients aged 70 years or older with NHL receiving rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP), a GA was administered before the start of chemotherapy. GA was composed of the Mini Nutritional Assessment (MNA), Groningen Frailty Indicator (GFI), Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE), Mini Mental State Examination (MMSE) and levels of albumin, creatinine, lactate dehydrogenase (LDH) and hemoglobin. Multivariate analyses were performed using logistic regression and the Cox regression model. After adjustment for sex, age, comorbidity and univariate laboratory values with p ≤ 0.1, abnormal MNA and GFI scores and low hemoglobin level were associated with not being able to complete the intended chemotherapy: odds ratio (OR) 8.29 (95% confidence interval [CI]: 1.24-55.6; p = 0.03), 9.17 (95% CI: 1.51-55.8; p = 0.02) and 5.41 (95% CI: 0.99-29.8; p = 0.05), respectively. Adjusted for sex, age, comorbidity, age-adjusted IPI and univariate laboratory values with p ≤ 0.1, frailty by GFI and low hemoglobin were associated with worse survival, with a hazard ratio (HR) of mortality of 2.55 (95% CI: 1.07-6.10; p = 0.04) and 4.90 (95% CI: 1.76-13.7; p = 0.002), respectively. We conclude that (risk of) malnutrition, measured with the MNA, frailty, measured with the GFI, and low hemoglobin level had additional predictive value for early treatment withdrawal, and GFI and hemoglobin were, independent of the age-adjusted IPI, predictive for an increased mortality risk.

Frailty and malnutrition predictive of mortality risk in older patients with advanced colorectal cancer receiving chemotherapy.

J Geriatr Oncol 2013 Jul 30;4(3):218-26. Epub 2013 Apr 30.

Institute of Mental Health, Bouman GGZ Rotterdam, The Netherlands. Electronic address:

Introduction: In general, geriatric assessment (GA) provides the combined information on comorbidity and functional, nutritional and psychosocial status and may be predictive for mortality outcome of cancer patients. The impact of geriatric assessment on the outcome of older patients with colorectal cancer treated with chemotherapy is largely unknown.

Methods: In a prospective study, 143 patients with colorectal cancer who were 70years and older were assessed before chemotherapy by Mini Nutritional Assessment (MNA), Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE), Groningen Frailty Indicator (GFI) and Mini Mental State Examination (MMSE).

Results: Fifty-four (38%) patients received adjuvant chemotherapy and 89 (62%) patients received palliative chemotherapy. Malnutrition and frailty were prevalent in 39 (27%, assessed by MNA) and 34 (24%, by GFI) patients, respectively; whereas cognitive impairment was prevalent in 19 (13%, by IQCODE) and 11 (8%, by MMSE) patients, respectively. In patients with palliative chemotherapy, poor MNA scores were associated with receiving less than 4cycles of chemotherapy (p=0.008). Poor MNA and GFI scores were associated with increased hazard ratios (HR) for mortality for patients with palliative chemotherapy: HR=2.76 (95% confidence interval [CI]: 1.60-4.77; p<0.001) and HR=2.72 (95% CI: 1.58-4.69; p<0.001), respectively, after adjustment for several clinical parameters.

Conclusions: Malnutrition and frailty were strongly associated with an increased mortality risk in patients who underwent palliative chemotherapy. Furthermore, a poor score on MNA was predictive for less tolerance of chemotherapy. Our findings may help the oncologist in future decision making and advice for elderly patients with colorectal cancer.
