522 Early Follow-Up Quality of Life and Mental Health of Patients with Congenital Vascular Malformations Cared for in a Multi-Disciplinary Specialist Center

Aim

To evaluate the early follow-up quality of life (QoL), pain and mental health of patients with congenital vascular malformation (CVM) receiving care by a single multi-disciplinary specialist center

Method

This was a prospective observational study. All patients with CVM who received care (supportive treatment only, open surgery, targeted pharmacological therapy, embolosclerotherapy), and had follow-up, between February 1st 2018 and January 31st 2020 were included. The health-related QoL, pain, and mental health were assessed with validated questionnaires: SF-36, VAS-P and HADS. The CVM were categorized into types – low-flow (LFVM) and high-flow (HFVM), and anatomical locations. Paired t-test was used for all analyses. P<0.05 were considered significant.

Results

110 patients (85 LFVM and 25 HFVM) with a mean age of 36.9 years were included. Significant improvement was found in the bodily pain domain of SF-36 and VAS-P (both P = 0.01) in all patients. However, only patients with HFVM reported significant improvement in the bodily pain domain of SF-36 (P=0.002) and VAS-P (P = 0.02). Patients who received supportive treatment only reported significant improvement in mental health (P=0.004) and social functioning (P=0.03) domains of SF-36. Meanwhile, patients treated with embolo-sclerotherapy reported significant improvement only in VAS-P (P=0.02). Patients who received targeted pharmacological therapy reported no significant early changes.

Conclusions

The effects of care on early follow-up QoL, pain and mental health of patients with CVM were heterogenous. Future research is required to understand the various factors that affect the QoL and mental health of these patients, as well as the holistic approaches to manage them.

New AMS 14C dates track the arrival and spread of broomcorn millet cultivation and agricultural change in prehistoric Europe

Broomcorn millet (Panicum miliaceum L.) is not one of the founder crops domesticated in Southwest Asia in the early Holocene, but was domesticated in northeast China by 6000 BC. In Europe, millet was reported in Early Neolithic contexts formed by 6000 BC, but recent radiocarbon dating of a dozen 'early' grains cast doubt on these claims. Archaeobotanical evidence reveals that millet was common in Europe from the 2nd millennium BC, when major societal and economic transformations took place in the Bronze Age. We conducted an extensive programme of AMS-dating of charred broomcorn millet grains from 75 prehistoric sites in Europe. Our Bayesian model reveals that millet cultivation began in Europe at the earliest during the sixteenth century BC, and spread rapidly during the fifteenth/fourteenth centuries BC. Broomcorn millet succeeds in exceptionally wide range of growing conditions and completes its lifecycle in less than three summer months. Offering an additional harvest and thus surplus food/fodder, it likely was a transformative innovation in European prehistoric agriculture previously based mainly on (winter) cropping of wheat and barley. We provide a new, high-resolution chronological framework for this key agricultural development that likely contributed to far-reaching changes in lifestyle in late 2nd millennium BC Europe.

Medical services use by patients before and after detoxification from benzodiazepine dependence

OBJECTIVE

The authors examined use of medical and mental health services before and after detoxification among a group of patients detoxified from benzodiazepines to see if the data suggested a reduction in service use and costs after detoxification, the so-called offset effect observed for treatment of alcohol and mental disorders.

METHODS

Through a medical record review, information was collected about medical service use for patients aged 40 and older who were detoxified from benzodiazepines at Scott and White Clinic and Hospital between 1987 and 1991.

RESULTS

Among the 76 patients, medical and mental health outpatient visits fell from an average rate of 25.4 visits per year before detoxification to 4.4 per year after detoxification. For the 44 patients with at least one inpatient stay besides the admission for detoxification, the mean number of inpatient days remained constant at three days per year before and after detoxification.

CONCLUSIONS

Although a retrospective record review suffers from a range of limitations, the findings suggest that detoxification from benzodiazepines may be effective in reducing use of outpatient medical and mental health services and presumably in reducing costs of care.

Modelling survivorship kinetics: a two-parameter model

A mathematical model of survivorship kinetics is presented. It takes into account both deterministic and stochastic aspects of survival curves. Earlier reports [Piantanelli: Arch Gerontol Geriatr 1986;5:107-118; Piantanelli: Ann NY Acad Sci 1988; 521:99-109] described a model capable of making distinct predictions on the mean and standard deviation of an index of physiological function, fitting data even in the tail of survivorship curves, and accounting for the selection of the cohort at advanced ages. However, it contains four parameters whose biological interpretation is unclear. In the present paper we propose a modification of the model which maintains the main characteristics of the previous one and, in addition, results in two significant improvements. First, the number of free parameters is reduced to only two, making much easier both their estimation and interpretation, particularly when the model is applied to data from various animal groups manipulated in different ways. Second, it is possible to relate the parameters to well-defined deterministic and stochastic factors: specifically, a deterministic component describing the environmental and genetic influence on physiological functions, and a stochastic component representing the fluctuating interactions of the living organism and its environment.
