Review
Major depressive disorder (MDD) is a common neuropsychiatry manifestation that is more prevalent lately. Many contributing factors are present (for example, neurochemical, physiological, pathophysiological, and endocrinological factors). Patients with increased serum parathyroid levels are usually linked to psychosis symptoms but not to depressive symptoms. We conducted this systematic review to explore a correlation between depressive disorder and increased serum parathyroid levels, a major endocrinological pathology, and help establish mental wellness in patients suffering from hyperparathyroidism. We conducted a thorough literature search using five major databases, MEDLINE, PubMed, PubMed Central (PMC), ScienceDirect, and Google Scholar, using three keywords-MDD, depression, and hyperparathyroidism. We included mixed method studies, including observational studies, non-randomized controlled trials, case reports, and review articles published in the last ten years, focusing on the adult and geriatric population (>18 years) and on depressive and anxiety symptoms associated with patients with hyperparathyroidism. We included 11 articles (seven observational studies + four case reports) for qualitative synthesis after screening the literature. The reviewed studies showed an association between high serum parathyroid level, high serum calcium level, high serum alkaline phosphatase level, low serum phosphorous level, and increased depressive neurocognitive symptoms. After a patient with hyperparathyroidism is treated for hypercalcemia or undergoes parathyroidectomy and the serum parathyroid levels are lowered, a decrease in severe depressive symptoms is noted. The qualitative analysis of the reviewed literature showed an association between major depressive disorder and hyperparathyroidism. This paper can guide clinicians to assess patients with increased serum parathyroid levels for depressive neuropsychiatric symptoms and plan treatment, as treatment of their hyperparathyroidism can significantly lower their depressive symptoms. More randomized controlled trials should be conducted to find the treatment effectiveness of depression in patients with hyperparathyroidism.

Meta-Analysis
A Systematic Review and Meta-analysis of Efficacy and Safety of Calcimimetic Agents in the Treatment of Secondary Hyperparathyroidism in Patients with Chronic Kidney Disease.
BACKGROUND
Some reports have pointed out that calcimimetics agents are effective in the treatment of secondary hyperparathyroidism (SHPT) in chronic kidney disease (CKD) patients, but there is no detailed description of the advantages and disadvantages of calcimimetics agents of SHPT in CKD patients. We tried to pool the published data to verify the effectiveness of calcimimetics agents and to compare the advantages and disadvantages of cinacalcet compared with control in the treatment of SHPT in CKD patients.
METHODS
We included eligible studies of published papers from January 1st, 2000 to December 31st, 2020 in Medline, Pubmed and Web of science databases, and the data were extracted for this meta-analysis.
RESULTS
Twenty-seven studies were eligible, and all the included studies were randomized controlled trials (RCT) including patients treated with long-term dialysis. The results indicated that calcimimetic agents can reduce the parathyroid hormone (PTH, pg/ml) level (WMD = -178.22, 95% CI: -238.57, -117.86, P < 0.00001), calcium (Ca, mg/dl) level (WMD = -0.71, 95% CI: -0.86, -0.55, P < 0.00001), phosphorus (P, mg/dl) level (WMD = -0.32, 95% CI: -0.55, -0.08, P = 0.008), calcium-phosphorus product level (WMD = -7.73, 95% CI: -9.64, -5.82, P < 0.00001). Calcimimetic agents increased the bone alkaline phosphatase (BSAP, ng/ml) levels and rate of achieving target PTH, and reduced osteocalcin levels and the rate of parathyroidectomy. Calcimimetic agents increased the total adverse events' rate, the rate of hypocalcemia and gastrointestinal side effects (nausea, vomiting, abdominal pain and diarrhea), but there was no significant difference in serious adverse events between the calcimimetic agent group and control group.
CONCLUSION
Calcimimetic agents can reduce the PTH level, Ca level, P level, calcium-phosphorus product level and do not increase serious adverse events.

Meta-Analysis Review
OBJECTIVE
We aim to evaluate the body of evidence reporting on normohormonal primary hyperparathyroidism (NHpHPT) patients to help guide their diagnosis, characterization and treatment.
BACKGROUND
Normohormonal primary hyperparathyroidism is a term used to describe patients with a normal PTH and elevated calcium levels. There is limited understanding regarding the presentation and appropriate management of these patients.
METHODS
A systematic review was conducted: abstract and full-text screening were independently conducted by 2 investigators. Odds ratios (OR), standard mean differences (SMD) and 95% confidence intervals were calculated.
RESULTS
Twenty-two studies were identified. Patients with NHpHPT were more likely to present with lower PTH (p < 0.00001) and calcium (p < 0.00001) levels. Intraoperatively, the NHpHPT group was 1.8 times more likely to undergo bilateral neck exploration (BNE) and harbor multigland disease. The rates of surgical cure were 93% in the NHpHPT and 96% in the pHPT groups (p = 0.0003).
CONCLUSION
Symptomatic patients with NHpHPT benefit from parathyroidectomy with prolonged intraoperative PTH monitoring, and a low threshold for conversion to BNE.

Review
The landscape of genetic forms of Parkinson's diseases (PD) has grown exponentially in recent years. Today, around 10% of PD cases are estimated to be of genetic etiology. However, the link between parkinsonism or tremor and chromosome disorders, both numerical and structural, has been neglected. We reviewed the occurrence and characteristics of parkinsonism and tremor syndromes in patients with chromosomic disorders. We searched PubMed for articles published until December 2018, using the non-MESH terms "Chromosomopathy," "karyotype," "chromosome," "aneuploidy," "deletion," "inversion," "insertion," "duplication," and "Parkinson," "Parkinsonism," "Tremor," and "Parkinsonian disorder." We restricted the search to human studies and selected articles for further analysis after abstract review. Tremor syndromes in which patients had another possible clinical reason for syndromes were excluded, as well as tremor syndromes associated with point mutations, imprinting syndromes, and patients presenting with other hyperkinetic disorders. Fifty-four articles were reviewed. Aneuploidies of sex chromosomes were the most common chromosomopathy. These patients more commonly exhibited postural and kinetic tremor, often meeting the description of essential tremor. In structural chromosomopathies, the most frequent association was PD and 22q11.2 deletion syndrome, but we found case reports and case series of several additional deletion and duplication syndromes. © 2021 International Parkinson and Movement Disorder Society.

Meta-Analysis Review
BACKGROUND
To evaluate the diagnostic accuracies of indocyanine green (ICG) fluorescence for identifying parathyroid glands during surgery and predicting the postoperative function.
METHODS
From six databases, 21 studies were finally included in the study. True-positive, true-negative, false-positive, and false-negative data were extracted for the analysis. The quality of each study was analyzed using the QUADAS-2 tool.
RESULTS
The sensitivity of ICG-based parathyroid gland identification was 0.9380 (95% CI [0.9003, 0.9621]). The diagnostic odds ratio for ICG-based prediction of parathyroid gland function was 54.5652 [13.2059, 225.4570]. The area under the summary receiver operating characteristic curve was 0.909. Fluorescence intensity-based prediction presented higher diagnostic accuracy than that of score-based prediction. The incidence of postoperative hypoparathyroidism was higher in the group with a zero ICG score compared to the high scored group.
CONCLUSIONS
Identification of parathyroid gland and prediction of postoperative function using ICG are valuable to patients undergoing thyroidectomy or parathyroidectomy.

Meta-Analysis Review
INTRODUCTION
The effects of denosumab on bone mineral density (BMD) and metabolism in patients with end-stage renal disease (ESRD) remain controversial. Hence, we performed a systematic review and meta-analysis of observational studies.
METHODS
The MEDLINE, EMBASE, and Cochrane Library databases were searched in June 2022 to identify studies that evaluated the risk of denosumab-associated hypocalcemia and changes in bone metabolism, changes in BMD from baseline to post-treatment in patients with ESRD.
FINDINGS
Twelve studies with 348 participants were included. The pooled incidence of hypocalcemia during denosumab treatment was 35.0% (95% confidence interval [CI], 25%-46%; I = 63.6%). There were no significant changes in either the serum calcium or phosphate levels from the baseline to post-treatment period; the mean differences were 0.04 mg/dL (95% CI, -0.12 to 0.20 mg/dL) and -0.39 mg/dL (95% CI, -0.89 to 0.12 mg/dL). We found significant changes in the alkaline phosphatase and parathyroid hormone levels; the standardized mean differences were -2.98 (95% CI, -5.36 to -0.59) and -3.12 (95% CI: -4.94 to -1.29), respectively. Denosumab may increase BMD, with mean differences of 9.10% (95% CI: 4.07%-14.13%) and 9.00% (95% CI: 5.93%-12.07%) for the femoral neck and lumbar spine, respectively.
DISCUSSION
Denosumab increased the BMDs of the lumbar spine and femoral neck in patients with ESRD. The onset of hypocalcemia must be carefully monitored during denosumab administration.

Meta-Analysis
The Efficacy and Safety of Medical and Surgical Therapy in Patients With Primary Hyperparathyroidism: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.
Both medical and surgical therapy represent potential management options for patients with asymptomatic primary hyperparathyroidism (PHPT). Because uncertainty remains regarding both medical and surgical therapy, this systematic review addresses the efficacy and safety of medical therapy in asymptomatic patients or symptomatic patients who decline surgery and surgery in asymptomatic patients. We searched Medline, Embase, Cochrane Central Register of Controlled Trials, and PubMed from inception to December 2020, and included randomized controlled trials in patients with PHPT that compared nonsurgical management with medical therapy versus without medical therapy and surgery versus no surgery in patients with asymptomatic PHPT. For surgical complications we included observational studies. Paired reviewers addressed eligibility, assessed risk of bias, and abstracted data for patient-important outcomes. We conducted random-effects meta-analyses to pool relative risks and mean differences with 95% confidence intervals and used Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) to assess quality of evidence for each outcome. For medical therapy, 11 trials reported in 12 publications including 438 patients proved eligible: three addressed alendronate, one denosumab, three cinacalcet, two vitamin D, and two estrogen therapy. Alendronate, denosumab, vitamin D, and estrogen therapy all increased bone density. Cinacalcet probably reduced serum calcium and parathyroid hormone (PTH) levels. Cinacalcet and vitamin D may have a small or no increase in overall adverse events. Very-low-quality evidence raised the possibility of an increase in serious adverse events with alendronate and denosumab. The trials also provided low-quality evidence for increased bleeding and mastalgia with estrogen therapy. For surgery, six trials presented in 12 reports including 441 patients proved eligible. Surgery achieved biochemical cure in 96.1% (high quality). We found no convincing evidence supporting an impact of surgery on fracture, quality of life, occurrence of kidney stones, and renal function, but the evidence proved low or very low quality. Surgery was associated with an increase in bone mineral density. For patients with symptomatic and asymptomatic PHPT, who are not candidates for parathyroid surgery, cinacalcet probably reduced serum calcium and PTH levels; anti-resorptives increased bone density. For patients with asymptomatic PHPT, surgery usually achieves biochemical cure. These results can help to inform patients and clinicians regarding use of medical therapy and surgery in PHPT. © 2022 The Authors.

Review
BACKGROUND
Hypoparathyroidism is the most common complication of bilateral operations in the central neck. No formal guidelines exist for the management of permanent hypoparathyroidism. Current treatment involving medical supplementation increases resource utilization and patient morbidity while decreasing quality of life. Parathyroid allotransplant (PA) offers a promising therapy; however, the optimal technique and role of immunosuppression (IS) in PA remain unclear.
METHODS
We performed a systematic search of the Embase, MEDLINE, and Cochrane Library databases to identify studies investigating PA for treatment of hypoparathyroidism.
RESULTS
A total of 24 studies including 186 individual allograft transplants in 146 patients were identified. Pooled graft survival for allotransplants in transplant-naïve vs prior transplant recipients was 29.9% and 80%, respectively.
CONCLUSIONS
PA using normocellular, fresh parathyroid donor tissue that is ABO-compatible, with induction and, at minimum, short-term maintenance IS presents a potentially safe and effective therapeutic option for permanent hypoparathyroidism in patients tolerating IS.

Coronaviruses are a big family of viruses that can infect mammalians and birds. In humans they mainly cause respiratory tract infections, with a large spectrum of severity, from mild, self-limited infections to highly lethal forms as severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome coronavirus (MERS-CoV) and Coronavirus Disease 2019 (COVID-19). Scanty data are reported for the involvement of endocrine glands in human coronaviruses, in particular SARS-CoV-2. In this review, we summarize endocrinological involvement in human coronaviruses, including data on animal coronaviruses. Avians, ferrets and bovine are affected by specific coronavirus syndromes, with variable involvement of endocrine glands. SARS-CoV and SARS-CoV-2 use angiotensin-converting enzyme 2 (ACE2) as a target receptor, so ACE2 plays a central role in viral transmission and initial organ involvement. Autoptic studies on SARS patients revealed that thyroid, parathyroid, pituitary gland, endocrine pancreas and especially adrenals and testis could be impaired by different mechanisms (direct damage by SARS-CoV, inflammation, vascular derangement and autoimmune reactions) and few clinical studies have evidenced functional endocrine impairment. Only few data are available for COVID-19 and gonads and endocrine pancreas seem to be involved. International endocrinological societies have brought some recommendations for the COVID-19 pandemic, but further studies need to be performed, especially to detect long-term hormonal sequelae.

Meta-Analysis
CONTEXT
Secondary hyperparathyroidism (SHPT) is a complication of chronic kidney disease (CKD) affecting mineral and bone metabolism and characterized by excessive parathyroid hormone (PTH) production and parathyroid hyperplasia.
OBJECTIVE
The objective of this analysis was to compare the efficacy and adverse effects of extended-release calcifediol (ERC) and paricalcitol (PCT) by assessing their effect on the biomarkers PTH, calcium, and phosphate in patients with non-dialysis CKD (ND-CKD).
METHODS
A systematic literature research was performed in PubMed to identify randomized control trials (RCTs). Quality assessment was done with the GRADE method. The effects of ERC vs PCT were compared using random effects in a frequentist setting.
RESULTS
Nine RCTs comprising 1426 patients were included in the analyses. The analyses were performed on 2 overlapping networks, due to nonreporting of outcomes in some of the included studies. No head-to-head trials were identified. No statistically significant differences in PTH reduction were found between PCT and ERC. Treatment with PCT showed statistically significant increases in calcium compared with ERC (0.2 mg/dL increase; 95% CI, -0.37 to -0.05 mg/dL). No differences in effects on phosphate were observed.
CONCLUSION
This network meta-analysis showed that ERC is comparable in lowering PTH levels vs PCT. ERC displayed avoidance of potentially clinically relevant increases in serum calcium, offering an effective and well-tolerated treatment option for the management of SHPT in patients with ND-CKD.
