Does Collaboration between General Practitioners and Pharmacists Improve Risk Factors for Cardiovascular Disease and Diabetes? A Systematic Review and Meta-Analysis.

Objective: To assess whether inter-professional, bidirectional collaboration between general practitioners (GPs) and pharmacists has an impact on improving cardiovascular risk outcomes among patients in the primary care setting. It also aimed to understand the different types of collaborative care models used. Study design: Systematic review and Hartung-Knapp-Sidik-Jonkman random effects meta-analyses of randomised control trials (RCTs) in inter-professional bidirectional collaboration between GP and pharmacists assessing a change of patient cardiovascular risk in the primary care setting. Data sources: MEDLINE, EMBASE, Cochrane, CINAHL and International Pharmaceutical Abstracts, scanned reference lists of relevant studies, hand searched key journals and key papers until August 2021. Data synthesis: Twenty-eight RCTs were identified. Collaboration was associated with significant reductions in systolic and diastolic blood pressure (23 studies, 5,620 participants) of -6.42 mmHg (95% confidence interval (95%CI) -7.99 to -4.84) and -2.33 mmHg (95%CI -3.76 to -0.91), respectively. Changes in other cardiovascular risk factors included total cholesterol (6 studies, 1,917 participants) -0.26 mmol/L (95%CI -0.49 to -0.03); low-density lipoprotein (8 studies, 1,817 participants) -0.16 mmol/L (95%CI -0.63 to 0.32); high-density lipoprotein (7 studies, 1,525 participants) 0.02 mmol/L (95%CI -0.02 to 0.07). Reduction in haemoglobin A1c (HbA1C) (10 studies, 2,025 participants), body mass index (8 studies, 1,708 participants) and smoking cessation (1 study, 132 participants) was observed with GP-pharmacist collaboration. Meta-analysis was not conducted for these changes. Various models of collaborative care included verbal communication (via phone calls or face to face), and written communication (emails, letters). We found that co-location was associated with positive changes in cardiovascular risk factors. Conclusion: Although it is clear that collaborative care is ideal compared to usual care, greater details in the description of the collaborative model of care in studies is required for a core comprehensive evaluation of the different models of collaboration.

Anti-Thyroid Antibodies and TSH as Potential Markers of Thyroid Carcinoma and Aggressive Behavior in Patients with Indeterminate Fine-Needle Aspiration Cytology.

BACKGROUND: Indeterminate fine-needle aspiration cytology (FNAC) imposes challenges in the management of thyroid nodules. This study aimed to examine whether preoperative anti-thyroid antibodies (Abs) and TSH are indicators of thyroid malignancy and aggressive behavior in patients with indeterminate FNAC. METHODS: This was a retrospective study of thyroidectomy patients from 2008 to 2016. We analyzed Abs and TSH levels, FNAC, and histopathology. Serum antibody levels were categorized as 'Undetectable', 'In-range' if detectable but within normal range, and 'Elevated' if above upper limit of normal. 'Detectable' levels referred to 'In-range' and 'Elevated' combined. RESULTS: There were 531 patients included. Of 402 patients with preoperative FNAC, 104 (25.9%) had indeterminate cytology (Bethesda III-V). Of these, 39 (37.5%) were malignant and 65 (62.5%) benign on histopathology. In the setting of indeterminate FNAC, an increased risk of malignancy was associated with 'Elevated' thyroglobulin antibodies (TgAb) (OR 7.25, 95% CI 1.13-77.15, P = 0.01) and 'Elevated' thyroid peroxidase antibodies (TPOAb) (OR 6.79, 95% CI 1.23-45.88, P = 0.008). Similarly, while still 'In-range', TSH ≥ 1 mIU/L was associated with an increased risk of malignancy (OR 3.23, 95% CI 1.14-9.33, P = 0.01). In all patients with malignancy, the mean tumor size was 8 mm larger in those with TSH ≥ 1 mIU/L (P = 0.03); furthermore, in PTC patients, 'Detectable' TgAb conferred a 4 × risk of lymph node metastasis (95% CI 1.03-13.77, P = 0.02). CONCLUSION: In this cohort, in indeterminate FNAC patients, Abs and TSH were associated with an increased risk of malignancy. Additionally, TgAb and TSH were potential markers of aggressive biology. As such, they may be diagnostic and prognostic adjuncts.

Body weight change is unpredictable after total thyroidectomy.

BACKGROUND: There is a common perception that total thyroidectomy causes weight gain beyond expected age-related changes, even when thyroid replacement therapy induces a euthyroid state. The aim of this study was to determine whether patients who underwent total thyroidectomy for a wide spectrum of conditions experienced weight gain following surgery. METHODS: We retrospectively studied 107 consecutive total thyroidectomy patients treated between January 2013 and June 2014. Medical records were reviewed to determine underlying pathology, thyroid status, use of antithyroid drugs and preoperative weight. Follow-up data were obtained from 79 patients at least 10 months post-operatively to determine current weight, the type of clinician managing thyroid replacement therapy and patient satisfaction with post-thyroidectomy management. RESULTS: The cohort was 73% female, with a mean age of 55.8 ± 15.7 years and a mean preoperative weight of 78.8 ± 17.5 kg. Commonest pathologies were multinodular goitre, Graves' disease, thyroid cancer and Hashimoto's thyroiditis. Preoperatively, 63.2% of patients were hyperthyroid. Mean weight change at follow-up was a non-significant increase of 0.06 ± 6.9 kg (P = 0.094). Weight change was not significant regardless of preoperative thyroid function status. This study did not demonstrate any significant differences in clinical characteristics (including post-operative thyroid-stimulating hormone) between the group with >2% weight gain and those who did not. CONCLUSIONS: This study did not reveal significant weight gain following thyroidectomy for a wide spectrum of pathologies. Specifically, preoperative hyperthyroidism, female gender and use of antithyroid medications do not predict weight gain after thyroid surgery.

Semi-Automatic Electronic Stent Register: a novel approach to preventing ureteric stents lost to follow up.

BACKGROUND: Ureteric stents are indispensable tools in modern urology; however, the risk of them not being followed-up once inserted poses medical and medico-legal risks. Stent registers are a common solution to mitigate this risk; however, manual registers are logistically challenging, especially for busy units. METHODS: Western Sydney Local Health District developed a novel Semi-Automatic Electronic Stent Register (SAESR) utilizing billing information to track stent insertions. To determine the utility of this system, an audit was conducted comparing the 6 months before the introduction of the register to the first 6 months of the register. RESULTS: In the first 6 months of the register, 457 stents were inserted. At the time of writing, two of these are severely delayed for removal, representing a rate of 0.4%. In the 6 months immediately preceding the introduction of the register, 497 stents were inserted, and six were either missed completely or severely delayed in their removal, representing a rate of 1.2%. A non-inferiority analysis found this to be no worse than the results achieved before the introduction of the register. CONCLUSION: The SAESR allowed us to improve upon our better than expected rate of stents lost to follow up or severely delayed. We demonstrated non-inferiority in the rate of lost or severely delayed stents, and a number of other advantages including savings in personnel costs. The semi-automatic register represents an effective way of reducing the risk associated with a common urological procedure. We believe that this methodology could be implemented elsewhere.

Laparoscopic repair of intra-abdominal bladder perforation in preschool children.

Intraperitoneal bladder rupture is uncommon in very young children, but its incidence may increase with increasing use of seat and lap belts. To the best of our knowledge, there are no prior reports of laparoscopic repair of this injury in children. We describe two recent cases and discuss useful technical points that facilitate a successful laparoscopic repair. Both our patients were preschool age girls who sustained seat and lap belt injuries. Contrast computed tomography scan suggested a large amount of free peritoneal fluid and cystogram confirmed intraperitoneal bladder perforation (isolated injury). The injury was repaired using delayed absorbable sutures and intracorporeal suturing (continuous in 1, interrupted in 1) using a 3 port laparoscopic technique. Meticulous peritoneal lavage was carried out to minimise urinary peritonitis and the bladder as well as the peritoneal cavity were drained. Check cystograms (day 7) revealed no leaks. Young girls appear to be at risk of intraperitoneal bladder injuries following lap belt injuries. After exclusion of life-threatening injuries and concurrent abdominal injuries which need rapid control or preclude pneumoperitoneum, a laparoscopic repair can be safely performed.

A case of calcified metastatic colorectal adenocarcinoma mimicking a benign lesion: pitfalls in diagnosis.

The radiological finding of a calcified intracranial lesion commonly represents a slow growing benign mass. Brain metastases originating from colorectal cancers are rare, occurring in approximately 2-3% of patients. Therefore the presence of a calcified brain lesion in a patient with a positive oncological history requires a high index of suspicion for brain metastases. Presented herein is a case of a frontoparietal calcified lesion initially overlooked as a benign tumour. Subsequent imaging following a neurological episode revealed a significant increase in size of the lesion with surrounding tissue oedema, prompting further investigation for suspicion of a calcified metastatic colorectal adenocarcinoma.
