She appeared at magistrates' court on 14 April 2021, where she did not enter any pleas and chose to have a trial at Crown Court.
Jarvis was ultimately charged with racially aggravated harassment, common assault and two counts of assault by beating. On 31 July 2020, she was arrested in Southend-on-Sea on suspicion of assault and racially aggravated public order. In March 2019, it was reported that Jarvis was glassed while on a night out.
On 19 April 2011, she gave birth to her son, Alfie. She gave birth to a daughter, Lillie Mae, on. Jarvis was born in Dagenham, East London. They showed their support to Jarvis by sharing their "regular" jobs on social media. Numerous tabloid newspapers wrote negatively about her working as a security guard, which was met with backlash from many celebrities who believed that the actress was "job shamed" by the press. In October 2019, Jarvis admitted that she had taken a "step back from acting" and began working as a security guard for B&M. In February 2018, she joined the BBC soap opera EastEnders as Hayley Slater. Jarvis won the British Independent Film Awards for her role. The film was in the running for the Palme d'Or at the 62nd Cannes Film Festival, winning the Jury Prize.
She played Mia, a troublesome and aggressive 15-year-old girl from an underclass family, passionate about dance. While initial morphine dose should be guided by patient age and not weight, subsequent doses must still be titrated according to effect.Jarvis was seen by a casting agent working for director Andrea Arnold, and was cast in her film Fish Tank, following a successful audition. Prescriptions for conventional analgesic regimens should include a dose range centred on values obtained from the above formula to allow for the large interpatient variation in each age group. Although previous studies have noted a correlation between patient age and the amount of opioid needed, this study quantifies this correlation and provides guidelines for opioid dosing. PCA allows patients the flexibility to titrate their own opioid dose if conventional analgesic regimens are to become more effective, they too need to allow for the wide interpatient variation in dose requirements. An estimate of these requirements for patients over the age of 20 years can be obtained from the formula: average first 24 h morphine requirement (mg) = 100 - age. Although the interpatient variability in PCA morphine doses was large (differences of up to 10-fold in each age group), the best predictor of PCA morphine requirement in the first 24 h after surgery (the amount required in the 24 h after the initial loading dose) was the age of the patient. In a subgroup of 78 of these patients, the effects of intraoperative and recovery room doses of opioid ('clinical' loading dose) were analysed. Factors included were age, sex, weight, operative site, verbal numeric pain score (at rest and on movement) and a nausea/vomiting score. The records of 1010 patients, under 70 years old, prescribed morphine via patient-controlled analgesia (PCA) after major operations were examined to see what factors might best predict the amount of morphine used in the first 24 h after surgery. Although a reduction in dose is often suggested for elderly patients over 70 years of age, age-related alterations to dose are generally not considered for younger patients. The dose of opioid prescribed for postoperative pain relief has traditionally been based on the weight of the patient.
