Atherosclerosis and depression: is carotid intima-media thicker in patients with depression compared to matched control individuals? A systematic review and meta-analysis.

OBJECTIVE: To investigate if there is an association between atherosclerosis and depression by using as imaging biomarker the carotid intima media thickness (cIMT), a surrogate marker for atherosclerosis. METHODS: PubMed/Medline, Embase and Cochrane databases were comprehensively searched to identify studies investigating the association between cIMT and depression. The results were pooled using a random-effects statistical model, appropriate for the expected high heterogeneity. Sensitivity and subgroup analyses were conducted where data was available. RESULTS: Overall, 22 and 13 studies met inclusion criteria for the qualitative and the quantitative synthesis, respectively, with a total of 4466 patients and 21,635 control participants. Results showed that cIMT is significantly higher in the depression, compared to the control groups with an overall mean difference of 0.07 mm (95% CI 0.04-0.10, p < 0.01). Subgroup analysis showed that diabetes could present as a confounding factor in patients with depression and an increased cIMT. CONCLUSIONS: This study confirms a significantly increased cIMT in patients with depression, compared with controls and suggests a possible bidirectional link between atherosclerosis and depression. An early screening of cardiovascular disease in individuals suffering with depression should be considered.

Transient Intraluminal Filament Middle Cerebral Artery Occlusion Stroke Model in Rats: A Step-by-Step Guide and Technical Considerations.

OBJECTIVE: Stroke is a leading cause of disability and mortality worldwide. Related research, although already providing significant insights regarding the underlying pathophysiology and potential treatment strategies, has been far from conclusive. Stroke models have been proved of extreme significance for laboratories around the world. In the present report, we have described in detail the most popular to date focal stroke model, the transient intraluminal filament middle cerebral artery occlusion (tifMCAO) model in rats. This model reliably mimics stroke in humans and also approximates endovascular thrombectomy. METHODS: The tifMCAO model was performed using Wistar rats weighing 300-400 g. We have described the surgical technique in a stepwise manner, with figures and/or high-definition video provided for each step. We have also introduced the use of complete arteriotomy of the external carotid artery stump during the procedure. RESULTS: We performed tifMCAO in 65 rats (male and female) involved in various experimental protocols. Although the initial mortality was 48%, practice reduced the rate to 10%. The mean procedural time was 53 minutes (range, 38-85 minutes). In a group of 8 rats ischemia was confirmed in 7 of them, with the stroke induction rate being 87.5%. CONCLUSIONS: The tifMCAO stroke model in rats is the most often used experimental model of focal ischemia because of its clinical relevance. We revisited the procedure and divided it, for instructional purposes, into 15 consecutive and distinct steps.

Anterior Cervical Discectomy and Fusion combined with thyroid gland surgery, a tailored case and literature review.

BACKGROUND: Nowadays, Anterior Cervical Discectomy and Fusion (ACDF) is considered a routine procedure. However, unexpected difficulties do occasionally arise, especially when anterior neck pathologies or anatomical variations are encountered. In such cases, proactive thinking will allow surgeons to tailor appropriately their approach and eliminate surgical risks. CASE PRESENTATION: We present the case of a 50-year-old male patient suffering from left upper limb radiculopathy that underwent a C7-T1 ACDF combined with a hemithyroidectomy. Excision of the right thyroid lobe was offered to the patient because of a goiter found during the preoperative work-up. Furthermore, the hemithyroidectomy provided a wide surgical field so the ACDF performed without excreting excessive traction to the adjacent neck structures. CONCLUSIONS: The patient had an uncomplicated post-operative. To our knowledge this is the first report of a planned hemithyroidectomy being carried out as the first step towards an ACDF procedure.

Spinal synovial cysts. A case series and current treatment options.

Synovial cysts constitute an uncommon degenerative lesion of the spine. They are usually asymptomatic but they may also cause symptoms of variable severity. The authors present three cases of such cysts, two in the lumbar region of a 55-year-old female and a 66 year old female and one in the cervical region of a 56-year-old male patient. All patients presented with radiculopathy. Magnetic Resonance Images revealed a cystic lesion at the L4/5 level in the first case, at L5/S1 level in the second case and at the C7/T1 junction level in the third case. Treatment has been microsurgical resection of all cysts with no post-operative complications and an excellent outcome. A discussion of current management options for this unusual disease is presented and a decision making flow chart is proposed.
