The COVID-19 related restrictions such as social distancing forced the search for feasible alternatives to the provision of care for patients with severe mental illness (SMI), with services opting for teletherapy as an substitute of face-to-face treatment.

To examine the implementation of teletherapy (telephone, videoconference) with patients with SMI during the COVID-19 first wave, and explore its associations with reduced hospitalisations after the first wave was over.

We performed a retrospective assessment of 270 records of patients visiting fifteen outpatient mental health services across Spain during 2020. We retrieved sociodemographic and clinical data, including modality of received therapy (in-person, telephone, videoconference) in three time points (before, during and after the first COVID-19 wave) and hospitalisation rates two, four and six months later.

During the first wave, services implemented teletherapy (telephone and videoconference) extensively, whilst they reduced face-to-face therapy, though this returned to previous levels after the first wave. Hospitalisations two months later did not differ between patients who received teletherapy, and those who did not (p=.068). However, hospitalisations were lower for the first group of patients four (p =.004) and six months later (p <.001). Multilevel analyses suggested that receiving teletherapy by videoconference during the first wave was the factor that protected patients most against hospitalisations six months later (OR=0.25; p=.012).

Our findings suggest that teletherapy plays a protective role against hospitalisations, especially when face-to-face therapy is not feasible. Therefore, it can be considered a valid alternative to ensure continuity of care to patients with SMI.

Several ADHD teenagers had difficult behavioral problems during countries closing down due to Covid-19 pandemic. One of these negative outcomes that parents cannot control children’s behavior toward desired unhealthy food and the impulsive consequences. It was a great opportunity to convention a teletherapy program as a tool of intervention seeking for help to reduce uncontrolled self- management and nutrition, which may affect all sorts of childhood growth, development, health and behavior. Furthermore, it can affects daily life and academic success.

We tried through our study to enhance the teletherapy as a therapeutic tool, during the first and second phase of Covid-19 pandemic, trying to help parents and patient to overcome the impulsive behavior by using a specific therapy technique based on nutrition and behavioral therapy

Our case study is a young girl aged 12:4 Yrs. In middle bilingual Arabic/ American School. The therapeutic program designed via teletherapy program using multi-media and thru multi phases sessions, to increase focus attention, emotional control and reduce impulsivity.

The outcomes of the enhancing nutrition and behavior teletherapy program, showed significant improvement for the specific goal. Sensible change in the girl’s impulsive behavior, more focusing, emotional control and more accepting about health nutrition habits.

The important finding that intensive, focused nutation and self-management techniques provided via teletherapy as solitary program brought benefits to individual’s, family and reduced impulsivity outcomes. In addition, family education to become an expert at learning simple techniques in daily life can brining a sense of pleasure for long life wellbeing.

Recent investigations demonstrate a strong potential for cobalt-60 (Co-60)-based teletherapy. The influence of the lower energy and penetration of a cobalt-60 beam compared with linear accelerator beams is negligible for intensity-modulated radiotherapy.

The aim of this research is to investigate source head fluence modulation in cobalt-60 teletherapy by using a three-dimensional (3D) physical compensator and secondary collimator jaw motion.

The Oncentra treatment planning system was used to develop three hypothetical plans by secondary collimator jaw motion. A clinical MDS Nordion Equinox 80 cobalt-60 teletherapy unit was used to acquire conventional water phantom beam characteristics. Fluence modulation experiments were executed at 5·0 cm depth in a PTW universal intensity-modulated radiation therapy (IMRT) verification phantom using calibrated Gafchromic external beam therapy 2 (EBT2) and RTQA2-1010 film batches. Gafchromic EBT2 film was used to sample intensity maps generated by secondary collimator jaw motion, yet Gafchromic RTQA2-1010 film sampled maps from the 3D physical compensator. The solid-state drives used were 75·0 and 74·3 cm for the Gafchromic EBT2 and Gafchromic RTQA2-1010 film measurements.

A 2D gamma index analysis was coded to compare EBT2 film measurements with Digital Imaging and Communications in Medicine data. This analysis was also used to verify film measurements versus Monte-Carlo simulations.

Lateral beam profiles generated from water phantom measurements were used to establish source head fluence modulation on the film measurements. The source head fluence of a cobalt-60 teletherapy beam could be modulated by secondary collimator jaw motion and using a 3D physical compensator.
