Psychiatrists and COVID-19: what is our role during this unprecedented time?

The declaration of a COVID-19 (Severe Acute Respiratory Syndrome - CoronaVirus2) pandemic by the World Health Organization in March 2020 has vastly changed the landscape in which mental health services function. Consideration is required to adapt services during this unusual time, ensuring continued provision of care for current patients, availability of care for patients with new-onset mental health difficulties and delivery of evidence-based support for healthcare professionals working with affected patients. Lessons can be learned from research carried out during the severe acute respiratory syndrome, Middle East respiratory syndrome and Ebola epidemics to ensure the delivery of efficient and effective mental health services both now and into the future.

Early intervention in psychosis in the North Lee Mental Health Services programme: a 5-year review.

OBJECTIVES: An Early Intervention in Psychosis (EIP) programme aims to engage patients in early assessment and phase-specific interventions which are the key elements of the Irish National Clinical Programme for psychosis. This study aims to describe and review the EIP programme offered by Cork's North Lee Mental Health Services over a 5-year period. METHODS: A retrospective descriptive study design was adopted to describe and review the EIP programme, patient demographics and treatments offered in the service over a 5-year period. RESULTS: A total of 139 patients were accepted into the programme over the 5-year period. The mean age of onset was 30 years (median = 28, SD = 9.9), and the mean duration of untreated psychosis was 8 months (median = 2.5, SD = 15.3). Two-thirds of patients were single on initial assessment, had a history of substance misuse and were unemployed. The majority of the cohort engaged with the keyworkers and occupational therapy but did not complete the full psychological or family programmes offered. Hospital admission was required for 12% of the cohort. CONCLUSIONS: Patients experiencing their first episode of psychosis can successfully be treated in the community with appropriate professional and family support. However, deficiencies were noted in physical health monitoring, as well as in the availability and engagement with family and psychological therapies. Properly resourced early interventions in psychosis teams are necessary to deliver services at internationally recognised standards.

The study to investigate the potential benefits of probiotics in yogurt, a patient-oriented, double-blind, cluster-randomised, placebo-controlled, clinical trial.

BACKGROUND: Probiotic functional foods are widely advertised to consumers primarily based on probiotic supplements. OBJECTIVE: Determine if consumption of yogurt containing a high dose of probiotics improves health in children ages 1-3 years attending daycare/school centers. SUBJECTS/METHODS: Double-blinded, randomized, placebo-controlled, allocation concealment clinical trial. SETTING: Outpatient participants in the Washington, DC area. PARTICIPANTS: 182 healthy children between the age of 1 and 3 years attending daycare/school at least 3 days a week. INTERVENTION: Active was a strawberry yogurt-based drink supplemented with Bifidobacterium animalis ssp. lactis (B. lactis) BB-12. The placebo was indistinguishable from the active drink, differing only in absence of the probiotic BB-12. Primary objective was to determine if consumption of a probiotic-containing yogurt-based drink decreases absences due to illnesses from daycare for children ages 1-3 years. Secondary was to determine if probiotic-containing yogurt-based drink improves overall parental satisfaction due to decreased absences from work and an overall healthier child. RESULTS: There were no significant differences in the days of missed school per group, with 51.9% in the active group and 47.1% in the placebo group missing at least 1 day of school throughout the study. Additionally, there were no differences in any secondary outcomes among the groups. CONCLUSIONS: Consumption of a yogurt-based drink delivering 10(10) CFU of Bifidobacterium animalis ssp. lactis (B. lactis) BB-12 per day did not decrease the number of days missed of school due to an illness. Additional independent research on the potential of BB-12 to reduce illness in children needs to be conducted.

Patients' attitudes towards "do not attempt resuscitation" status.

INTRODUCTION: The decision of "do not attempt resuscitation" (DNAR) in the event of cardiopulmonary arrest is usually made when the patients are critically ill and cannot make an informed choice. Although, various professional bodies have published guidelines, little is know about the patients' own views regarding DNAR discussion. AIM: The aim of this study was to determine patients' attitudes regarding discussing DNAR before they are critically ill. METHODS: A prospective study was performed in a general out patients department. A questionnaire was distributed to consecutive outpatients along with an explanatory leaflet in the adult outpatient clinic. RESULTS: 364 patients completed the questionnaire (response rate 77%). 90% of respondents wanted all patients to be asked regarding DNAR decision at some point during a hospital admission. The majority would not find a DNAR discussion distressing. Only 10% would find it upsetting, however, 48% of these still wanted a discussion. 37% of respondents wanted to discuss DNAR decisions on admission; 32% in outpatients; 17% at consent for surgery, 14% when they are critically ill. 87% of respondents would not object to their relatives being involved in making decisions about their resuscitation status. However, only 12% of the subjects in the study had been involved in discussing the resuscitation status of a relative and 21% would not be comfortable to discuss a relative's resuscitation status. Although 33% of patients preferred their resuscitation status to simply be documented within their clinical notes, 77% wanted it to be more easily accessible. CONCLUSIONS: This study suggests that contrary to current practice most patients want to discuss their DNAR status prior to becoming critically ill. This includes half of the small number that find it distressing to discuss. Although most patients are comfortable with relatives being involved in discussing DNAR, a significant proportion do not want their relatives to be asked. Furthermore, once a decision has been made, the majority of patients want it to be more accessible than current practice allows.

The clinical management and outcome of venous ulcers in legs with deep-venous obstruction.

OBJECTIVE: as a result of a serious complication from compression bandaging in a patient with venous ulceration and deep-vein obstruction, a policy of incremental compression in such limbs has been developed. The purpose of this retrospective study is to review the outcome of this policy. DESIGN: limbs with deep-venous obstruction (stenosis or occlusion) were treated initially with 3-layer compression bandaging and reviewed 24 h later. If 3-layer bandaging was tolerated, it was re-applied for a further 48 h. If there were no problems, then 4-layer bandaging was applied and the patient reviewed at 24 and 72 h. If 4-layer bandaging could not be tolerated, the limb was returned to 3-layer bandaging. RESULTS: of 325 limbs seen in a venous-ulcer clinic, 22 (7%) had deep-vein obstruction. Fifteen (68%) limbs were able to tolerate 4-layer bandaging, five (23%) could tolerate 3-layer bandaging and two limbs (9%) could only tolerate class 2 compression hosiery. The overall 1-year healing rate was 55%. There were no serious complications from bandaging. CONCLUSIONS: a protocol of incremental compression bandaging is safe in ulcerated legs with deep-vein obstruction and produces healing in up to 55% of cases.

Patients' perception of surgical services in a district general hospital.

BACKGROUND: In addition to studying the outcomes of surgery in terms of mortality and morbidity rates and performance, it is also important to consider how patients perceive the delivery of the service given to them. METHODS: A patient satisfaction survey was carried out by the Surgical Epidemiology and Audit Unit of the Royal College of Surgeons of England, on patients undergoing surgical procedures by the Department of Surgery at Wrexham Maelor Hospital. No day cases were included in the study. Two hospitals in southern England (undergoing the same survey) designated X and Y were used for comparison. RESULTS: Some 2000 questionnaires were sent out twice; 1666 subjects (83 per cent) responded to the first questionnaire and 1445 (87 per cent) of these responded to a second questionnaire 6 weeks later (overall response 72 per cent). A total of 35 per cent of patients were older than 65 years of age. Some 76 per cent of patients with a malignant condition were seen within 4 weeks of referral compared with 38 per cent of those with a benign condition (P < 0.0001). A total of 78 per cent of patients with cancer were admitted within 4 weeks compared with 84 and 88 per cent in hospitals X and Y. Some 23 per cent of patients were admitted as an emergency. Eighteen per cent of patients did not know who presented a consent form to them before surgery compared with 13 and 17 per cent in hospitals X and Y (P < 0.0001). Some 26 per cent of patients perceived that they had complications after surgery compared with 27 and 25 per cent for hospitals X and Y. A total of 35 per cent of patients did not receive a follow-up appointment and 20 per cent of these patients were unhappy about this. Two areas of major concern revealed by the responses were the lack of written information and the overall poor scores generally attained by the emergency admission ward. However, 94 per cent of patients said that they would return to the same consultant. CONCLUSION: Patients were generally happy with their surgical care and there was little difference between the three hospitals studied. Lower scores were given when patients were admitted to emergency admission wards. Higher scores were given when patients received printed information.

Role of superficial venous surgery in the treatment of venous ulceration.

BACKGROUND: The aim of this study was to determine the ability of superficial venous surgery to heal venous ulcers in lower legs with isolated superficial venous incompetence. METHODS: This was a prospective study of patients recruited from a venous ulcer assessment clinic. Ulcers were considered venous if the ankle : brachial pressure index was greater than 0.8 and duplex imaging showed venous reflux. Patients with isolated superficial venous incompetence were offered saphenofemoral and/or saphenopopliteal surgery. Neither perforator surgery, skin grafting nor postoperative compression hosiery or bandaging was used. RESULTS: A total of 122 legs with normal deep veins underwent superficial venous surgery. Ninety procedures (74 per cent) were done under local and 32 (26 per cent) under general anaesthesia. Sixty operations (49 per cent) were done as a day case. The median time to healing was 18 (95 per cent confidence interval 14-21) weeks and the cumulative 6-, 12- and 18-month healing rates were 57, 74 and 82 per cent respectively. CONCLUSION: In patients with venous ulceration and isolated superficial venous incompetence, superficial venous surgery can produce ulcer healing in the majority of patients without the need for perforator surgery, postoperative compression bandaging or skin grafting.

Vascular surgical society of great britain and ireland: role of superficial vein surgery in treatment of venous ulceration

BACKGROUND: Recent colour duplex studies of patients presenting with venous ulceration in the community have shown that between 55 and 60 per cent have isolated superficial venous insufficiency. Previous studies of the role of superficial surgery in the treatment of venous ulceration have applied postoperative compression bandaging and therefore it has not been possible to determine the role of superficial surgery in promoting ulcer healing. The purpose of this prospective study was, therefore, to examine the healing rate after superficial surgery in patients with isolated superficial venous incompetence and venous ulceration who did not undergo postoperative compression bandaging. METHODS: Patients with isolated superficial venous incompetence, as demonstrated by colour duplex scanning and an ankle : brachial pressure index greater than 0.8, underwent saphenofemoral or saphenopopliteal disconnection under local anaesthesia, or a high tie and strip under general anaesthesia. Compression bandaging was not applied after operation. Patients were followed regularly after surgery and the endpoint was ulcer healing. RESULTS: Between May 1994 and July 1997, 122 legs with venous ulceration and isolated superficial venous incompetence underwent superficial surgery. Ninety-three (76 per cent) had long saphenous incompetence alone, 13 (11 per cent) had short saphenous incompetence alone and 16 (13 per cent) had combined long and short saphenous incompetence. The median (range) patient age was 72 (28-94) years and the median duration of ulceration was 32 weeks (range 2 weeks to 32 years). The median (range) ulcer area was 9 (1-500) cm2. Ninety patients (74 per cent) had a local anaesthetic procedure while 32 (26 per cent) had general anaesthesia. Of patients who had long saphenous surgery, 69 had high ligation only and 24 had high ligation and strip. The healing rate by life-table analysis was 58 per cent at 6 months, 73 per cent at 1 year and 82 per cent at 18 months. Clinical review and colour duplex examination of patients with ulcers that had failed to heal (n = 18) showed that two had recurrent superficial to deep connections; the remainder had fixed ankle joints or severe osteoarthritis of the hip and knee. CONCLUSION: Superficial venous surgery in patients with isolated superficial venous incompetence and venous ulceration can achieve a very high healing rate in the absence of postoperative compression.

Venous ulceration and continuous flow in the long saphenous vein.

OBJECTIVE: To determine the clinical significance of continuous flow in the long saphenous vein in limbs with venous ulceration. DESIGN: Retrospective review. PATIENTS AND METHODS: Review of 1608 consecutive limbs undergoing colour duplex scanning for venous disease over a 43 month period. RESULTS: Continuous flow in the long saphenous vein is seen in 8% of limbs with venous ulceration and in 37% of limbs with deep venous obstruction. Sixty-six per cent of ulcerated limbs with continuous flow in the long saphenous vein had deep venous obstruction, 27% had deep venous reflux with cellulitis and 7% had lymphoedema in addition to venous ulceration. CONCLUSION: Continuous flow in the long saphenous vein in patients with venous ulceration should alert the clinician to the possibility of deep venous obstruction. Such limbs should be treated by compression bandaging with extreme caution.

The influence of total knee arthroplasty on lower limb blood flow.

Ischaemic complications of total knee arthroplasty (TKA) are unusual and tend to occur in patients with peripheral vascular disease (PVD). A prospective study was undertaken to investigate the effect of TKA on blood flow in patients without clinical evidence of PVD. Ankle brachial index (ABI) did not alter post-operatively and no changes in arterial waveforms were found. Unless there is clinical evidence of PVD, TKA under tourniquet control is therefore very unlikely to cause ischaemic complications.

Assessment of peritonism in appendicitis.

The aim of this study was to evaluate the accuracy of different methods of demonstrating right iliac fossa peritonism in appendicitis. The methods used were cat's eye symptom (pain on going over a bump in the road), cough sign, right iliac fossa tenderness, percussion tenderness, rebound tenderness and guarding. A series of 100 consecutive patients with a median age of 25 years (range 4-81 years), presenting with right iliac fossa pain were studied prospectively; the male:female ratio was 39:61. In all, 58 patients underwent operation, 44 had appendicitis confirmed on histology. Fourteen patients had a normal appendix removed; 11 were women aged between 16 and 45 years. Cat's eye symptom and cough sign were sensitive indicators of appendicitis (sensitivity 0.80 and 0.82, respectively), but were not specific (specificity 0.52 and 0.50, respectively) and therefore inaccurate (accuracy 64%). Percussion tenderness was less sensitive (sensitivity 0.57) but more specific (specificity 0.86). Rebound tenderness proved to be sensitive (sensitivity 0.82), specific (specificity 0.89) and accurate (accuracy 86%). Thus, rebound tenderness had a positive predictive value of 86% compared with 56% and 57% for cough sign and cat's eye symptom, respectively. In the difficult diagnostic group of young women, the positive predictive value of rebound tenderness was 88% compared with 58% and 56% for cat's eye symptom and cough sign. Appendicitis remains a difficult diagnosis, particularly in young women. Rebound tenderness still has an important role to play in clinical assessment.

Vascular trauma in civilian practice.

Vascular trauma is associated with major morbidity and mortality, but little is known about its incidence or nature in Britain. A retrospective study of 36 patients requiring operative intervention for vascular trauma under one vascular surgeon over a 6-year period was undertaken. Twenty-four patients suffered iatrogenic trauma (median age 61 years); including cardiological intervention (19), radiological intervention (2), varicose vein surgery (1), umbilical vein catherisation (1) and isolated hyperthermic limb perfusion (1). There were 23 arterial and three venous injuries. Twelve patients had accidental trauma (median age 23 years). Three of the ten patients with blunt trauma were referred for vascular assessment before orthopaedic intervention, two after an on-table angiogram and five only after an initial orthopaedic procedure (range of delay 6 h to 10 days). Injuries were arterial in nine, venous in two and combined in one. Angiography was obtained in six patients, and in two patients with multiple upper limb fractures identified the site of injury when clinical localisation was difficult. A variety of vascular techniques were used to treat the injuries. Two patients died postoperatively and one underwent major limb amputation. Thirty-two (89%) remain free of vascular sequelae after a median follow-up of 48 months (range 3-72 months). Vascular trauma is uncommon in the United Kingdom. To repair the injuries a limited repertoire of vascular surgery techniques is needed. Therefore, vascular surgical assessment should be sought at an early stage to prevent major limb loss.

The use and impact of a daily general surgical emergency operating list in a district general hospital: a prospective study.

Daytime emergency operating lists (EOL) have been shown to reduce out-of-hours operating but problems with their introduction have been reported. A six-month prospective study of EOL and unscheduled operations (USO) was undertaken. Two firms use their EOL differently--one including mostly emergencies, the other including a number of urgent elective cases. After the introduction of EOL only 9 per cent of emergency operations were performed after midnight. Including urgent elective cases on the EOL allowed full use of available theatre time but meant that proportionately more emergency operations were unscheduled. A senior surgeon was involved with 75 per cent of EOL and 36 per cent of USO operations, and a senior anaesthetist with 52 per cent of EOL and 14 per cent of USO. Senior anaesthetic involvement would have been greater if there were more senior staff. There had been a marked increase in the number of USO over the four years previous to this study. EOL do reduce out-of-hours operating and allow excellent supervision and therefore training opportunities. Care must be taken with the case mix to balance full use of theatre time with reduction in out-of-hours operating.

The importance of pubic pain following childbirth: a clinical and ultrasonographic study of diastasis of the pubic symphysis.

This study aimed to investigate the diagnosis and consequences of pubic symphysis diastasis postpartum, in particular the use of ultrasonography to measure interpubic gap. It was a prospective follow-up study, which included an ultrasonographic comparison between symptomatic mothers and controls, set in Morriston Hospital, Swansea. Nine women presenting with unusual pubic pain post-partum were included: there were no exclusion criteria. Forty-two controls were also studied: the only exclusion criterion was unusual pubic pain. Interpubic gap was measured with ultrasonography. Follow up was undertaken for a median of 37 months (range 2-57). An abnormal interpubic gap was found in all symptomatic women. The incidence of diastasis was found to be at least one in 800 deliveries and significant long-term disability was found in three women. Diastasis is commoner than generally acknowledged and its consequences may be severe. Interpubic gap confirms diagnosis but does not appear to predict outcome. Ultrasonography aids diagnosis and follow up.

Plasma cholesterol ester fatty acids: a new biochemical abnormality in obstructive jaundice.

Changes in fatty acid patterns may explain many of the observed abnormalities found in obstructive jaundice. This study looked at fatty acids in plasma cholesterol esters, in a group of patients with obstructive jaundice and a matched group of controls. Significant abnormalities were demonstrated, most importantly a fall in essential fatty acids, in the jaundiced group. Overall the saturation of this fraction, as assessed by double bond index, rose. The essential fatty acids are important as factors in membrane function and as precursors of eicosanoids. The abnormalities found in this study provide further evidence of the significance of EFA in patients with obstructive jaundice.
