BACKGROUND
Congenital hypothyroidism (CH) is the leading cause of preventable mental retardation, which is currently not universally screened in India. Knowledge of the country-specific prevalence of the disease can guide in establishing a universal screening program.
METHODS
We performed a systematic review and meta-analysis to assess the prevalence, screen positivity rates, compliance to recall and etiology of CH in India. The databases of PubMed, Embase, Google scholar and IMSEAR were searched on 1 October 2021. All observational studies reporting at least one of the outcomes of interest were included. Two reviewers independently extracted the data and appraised the quality of studies using the Joanna Briggs tool for prevalence studies. Estimates were pooled using a random-effects model with double arcsine transformation (MetaXL software). PROSPERO database registration number was CRD42021277523.
FINDINGS
Of the 2 073 unique articles retrieved, 70 studies were eligible for inclusion. The prevalence of CH (per 1 000 neonates screened) was 0·97 (95% confidence intervals/CI: 0·9, 1·04) in non-endemic areas (54 studies and 819 559 neonates), 79 (95% CI: 72, 86) in endemic areas (3 studies, 5 060 neonates), 50 (95% CI: 31, 72) in neonates born to mothers with thyroid disorders, and 14 (95% CI: 8, 22) in preterm neonates. At thyroid stimulation hormone cut-off of 20 mIU/L, the screen positivity rates were 5·6% (95% CI: 5·4%, 5·9%) for cord blood samples and 0·19% (95% CI: 0·18%, 0·2%) for postnatal sample. About 70% (95% CI: 70, 71) of screen positive neonates were retested with diagnostic tests. Among neonates with permanent hypothyroidism, thyroid dysgenesis 56·6% (95% CI: 50·9%, 62·2%) was more common than dyshormonogenesis 38·7% (95% CI: 33·2%, 44·3%).
INTERPRETATION
The prevalence of congenital hypothyroidism in India is higher than global estimates. Screen positivity rate was higher for cord blood screening when compared to postnatal screening. Compliance with confirmatory testing was higher for cord blood screening.
FUNDING
The study was not funded by any source.

Review
BACKGROUND
Cognitive decline occurs in all persons during the aging process and drugs can only alleviate symptoms and are expensive. Some researches demonstrated that Tai Chi had potential in preventing cognitive decline while others' results showed Tai Chi had no influence on cognitive impairment. Therefore, we conduct a systematic review and meta-analysis to assess the efficacy and safety of cognitive impairment patients practicing Tai Chi.
METHODS
A comprehensive literature search was carried out in multiple databases, including PubMed, Cochrane, MEDLINE (Ovid), Web of Science, Embase, Scopus, PsycInfo (Ovid), CKNI, Wan Fang, VIP, SinoMed, and ClinicalTrails, from their inception to 1 July 2020 to collect randomized controlled trials about practicing Tai Chi for patients with cognitive impairment. Primary outcomes included changes of cognitive function and secondary outcomes included changes of memory functions. Data were extracted by two independent individuals and Cochrane Risk of Bias tool version 2.0 was applied for the included studies. Systematic review and meta-analysis were performed by RevMan 5.3 software.
RESULTS
The results included 827 cases in 9 studies, of which 375 were in the experimental group and 452 were in the control group. Meta-analysis showed that Mini-Mental State Examination WMD = 1.52, 95% CI [0.90, 2.14]; Montreal Cognitive Assessment WMD = 3.5, 95% CI [0.76, 6.24]; Clinical Dementia Rating WMD = -0.55, 95% CI [-0.80, -0.29]; logical memory delayed recall WMD = 1.1, 95% CI [0.04, 2.16]; digit span forward WMD = 0.53, 95% CI [-0.65, 1.71]; and digit span backward WMD = -0.1, 95% CI [-0.38, 0.19]. No adverse events were reported in the included articles.
CONCLUSION
There is limited evidence to support that practicing Tai Chi is effective for older adults with cognitive impairment. Tai Chi seems to be a safe exercise, which can bring better changes in cognitive function score.

Meta-Analysis
The present meta-analysis aimed to quantify sex differences in verbal working memory and to examine potential moderators of these differences. We examined 802 effect sizes from 478 samples in 284 studies in a multilevel meta-analysis. Results revealed a small overall female advantage (g = .028, 95% CI [.006, .050]). In the overall sample, results showed that sex differences differed across tasks. Specifically, the female advantage was significant for cued tasks (g = .079, 95% CI [.030, .128]) and Free Recall tasks (g = .145, 95% CI [.102, .188]) whereas there was a male advantage on Complex Span (g = -.042, 95% CI [-.083, -.002]), and no sex differences on Serial Recall (g = .003, 95% CI [-.055, .050]), and Simple Span tasks (g < .001, 95% CI [-.034, .033]). Within each task, we found that recall direction, stimulus type, presentation format, response format, and age accounted for significant variance in at least 1 of the tasks. Analyses provided no evidence of a publication bias, although the female advantage varied as a function of sample source, whether the title made reference to sex, and whether authors had to be contacted to obtain relevant data. Results are discussed in terms of their implications for sex differences in episodic memory and in the context of clinical applications and theory building.

INTRODUCTION
Short-form versions of the Montreal Cognitive Assessment (SF-MoCA) are increasingly used to screen for dementia in research and practice. We sought to collate evidence on the accuracy of SF-MoCAs and to externally validate these assessment tools.
METHODS
We performed systematic literature searching across multidisciplinary electronic literature databases, collating information on the content and accuracy of all published SF-MoCAs. We then validated all the SF-MoCAs against clinical diagnosis using independent stroke (n = 787) and memory clinic (n = 410) data sets.
RESULTS
We identified 13 different SF-MoCAs (21 studies, n = 6477 participants) with differing test content and properties. There was a pattern of high sensitivity across the range of SF-MoCA tests. In the published literature, for detection of post stroke cognitive impairment, median sensitivity across included studies: 0.88 (range: 0.70-1.00); specificity: 0.70 (0.39-0.92). In our independent validation using stroke data, median sensitivity: 0.99 (0.80-1.00); specificity: 0.40 (0.14-0.87). To detect dementia in older adults, median sensitivity: 0.88 (0.62-0.98); median specificity: 0.87 (0.07-0.98) in the literature and median sensitivity: 0.96 (range: 0.72-1.00); median specificity: 0.36 (0.14-0.86) in our validation. Horton's SF-MoCA (delayed recall, serial subtraction, and orientation) had the most favorable properties in stroke (sensitivity: 0.90, specificity: 0.87, positive predictive value [PPV]: 0.55, and negative predictive value [NPV]: 0.93), whereas Cecato's "MoCA reduced" (clock draw, animal naming, delayed recall, and orientation) performed better in the memory clinic (sensitivity: 0.72, specificity: 0.86, PPV: 0.55, and NPV: 0.93).
CONCLUSIONS
There are many published SF-MoCAs. Clinicians and researchers using a SF-MoCA should be explicit about the content. For all SF-MoCA, sensitivity is high and similar to the full scale suggesting potential utility as an initial cognitive screening tool. However, choice of SF-MoCA should be informed by the clinical population to be studied.

Review
To determine the effect of distributed practice (spacing out of study over time) and retrieval practice (recalling information from memory) on academic grades in health professions education and to summarise a range of interventional variables that may affect study outcomes. A systematic search of seven databases in November 2022 which were screened according to predefined inclusion criteria. The Medical Education Research Study Quality Instrument (MERSQI) and Newcastle-Ottawa Scale-Education (NOS-E) were used to critically appraise eligible articles. A summary of interventional variables includes article content type, strategy type, assessment type and delay and statistical significance. Of 1818 records retrieved, 56 were eligible for inclusion and included a total of 63 experiments. Of these studies, 43 demonstrated significant benefits of distributed practice and/or retrieval practice over control and comparison groups. Included studies averaged 12.23 out of 18 on the MERSQI and averaged 4.55 out of 6 on the NOS-E. Study designs were heterogeneous with a variety of interventions, comparison groups and assessment types. Distributed practice and retrieval practice are effective at improving academic grades in health professions education. Future study quality can be improved by validating the assessment instruments, to demonstrate the reliability of outcome measures. Increasing the number of institutions included in future studies may improve the diversity of represented study participants and may enhance study quality. Future studies should consider measuring and reporting time on task which may clarify the effectiveness of distributed practice and retrieval practice. The stakes of the assessments, which may affect student motivation and therefore outcomes, should also be considered.

Meta-Analysis Review
Difficulty in accessing specific memories, referred to as reduced memory specificity or overgeneral memory (OGM), has been established as a marker of clinical depression. However, it is not clear if this deficit persists following the remission of depressive episodes. The current study involved a systematic review and meta-analysis of empirical studies with the aim of establishing whether remitted depression was associated with retrieving fewer specific and more overgeneral autobiographical memories. Seventeen studies were identified as eligible. The results indicated that people with remitted depression recalled fewer specific memories (k = 15; g = -0.314, 95% CI [-0.543; -0.085], z = -2.69, p = .007) and more categoric memories (k = 9; g = 0.254, 95% CI [0.007; 0.501], z = 2.02, p = .043) compared to people who had never been depressed. Given these deficits have elsewhere been shown to be prognostic of future depressive symptoms, these findings suggest that reduced memory specificity/overgeneral memory persists following remission and may be a risk factor for future episodes of depression in those that are in remission. The findings are discussed in terms of how this knowledge might influence clinical understanding of relapse prevention and maintenance of remission in those with a history of depression.

Review
We sought to summarize, in a systematic review, the effectiveness of songs to support learning, performance, and recall of quality characteristics of cardiopulmonary resuscitation (CPR) compression rate, and depth. We systematically reviewed the literature from eight academic indexes from the fields of medicine, nursing, allied health, and education, from 2014 to 2020 to identify studies that evaluated an intervention of song use during CPR training against control and reported outcomes of compression rate and depth. There were 185 studies initially identified for review, eight met criteria for inclusion and analysis. For the critical outcome of compression depth, a pooled song group (n=446) when compared to a non-song group (n=443) demonstrated higher odds of being in the recommended range (OR 3.47). All studies, however, performed an average compression depth shallower than recommended guidelines in each arm. The available literature, we found, utilized heterogenous methodology and was at high risk of bias. When pooled, there were trends towards improved CPR metric performance in groups who were exposed to songs during treatment, though this only reached significance when groups were tested at >30 days from initial exposure. Findings of lower compression rates in the song groups suggest that song selection should favor beats per minute closer to the midpoint of the 100-120 ideal range to allow for variation when used as mental metronomes.

Comparative Study Meta-Analysis
OBJECTIVE
To compare recall of complications and surgical details discussed during informed consent and perception of the consent process in patients undergoing emergent vs elective surgery.
METHODS
Studies were identified from PubMed, Cochrane, Web of Science, and Scopus from January 1, 1966, through April 18, 2018. Included studies compared patient recall and perception regarding informed consent in those undergoing emergent vs elective surgery. Pooled odds ratios (ORs) were calculated for recall of complications and surgical details, patient satisfaction, perception of sufficient information being delivered on surgical risks, report of having read written consent, and factors that interfered with consent.
RESULTS
Eleven observational studies (3178 patients) were included. The rate of recall of surgical complications (255 of 504 [50.6%] vs 321 of 446 [72.0%]; OR, 0.29; 95% CI, 0.11-0.80) was lower in patients undergoing emergent vs elective surgery. Meta-analysis revealed a decreased rate of patient satisfaction with the consent process (319 of 459 [69.5%] vs 882 of 1064 [82.9%]; OR. 0.53; 95% CI, 0.34-0.83) and fewer patients having read the consent form (130 of 395 [32.9%] vs 424 of 714 [59.4%]; OR, 0.35; 95% CI, 0.27-0.46) when undergoing emergent compared with elective surgery. Patients undergoing emergent surgery listed pain, analgesic medications, and fatigue as factors likely to interfere with consent.
CONCLUSION
Patients undergoing emergent surgery have poor recall of the informed consent process and surgical complications. Furthermore, patients report lower rates of satisfaction, and with fewer patients reading written consent documentation, our findings illuminate problems with the current communication process. There is a need to develop effective tools to improve informed consent in emergency surgery.

Ever since Endel Tulving first distinguished between episodic and semantic memory, the remember/know paradigm has become a standard means of probing the phenomenology of participants' memorial experiences by memory researchers, neuropsychologists, neuroscientists, and others. However, this paradigm has not been without its problems and has been used to capture many different phenomenological experiences, including retrieval from episodic versus semantic memory, recollection versus familiarity, strength of memory traces, and so on. We first conducted a systematic review of its uses across the literature and then examined how memory experts, other cognitive psychology experts, experts in other areas of psychology, and lay participants (Amazon Mechanical Turk workers) define what it means when one says "I remember" and "I know." From coding their open-ended responses using a number of theory-bound dimensions, it seems that lay participants do not see eye to eye with memory experts in terms of associating "I remember" responses with recollection and "I know" responses with familiarity. However, there is general consensus with Tulving's original distinction, linking remembering with memory for events and knowing with semantic memory. Recommendations and implications across fields are discussed.

SARS-CoV-2 infection has a wide range of both acute and long-term symptoms. Memory alterations have been frequently reported in studies that explore cognition. The main objective of the systematic review is to update and further analyze the existing evidence of objective memory impairments in long-COVID-19 considering sample and study design characteristics, as well as to explore associations between memory performance and their epidemiological, clinical, and pathological features. A total of 13 studies were identified by searching in PubMed, Web of Science, and PsycInfo databases up to May 6, 2022. Most studies evaluated verbal component of memory in the short-term and long-term recall up to 30 min and mainly performed a single assessment completed at 4-6 months after the infection. The samples mainly consisted of middle-aged adults that required hospitalization. Samples were not stratified by sex, age, and severity. Poor verbal learning was reported in most cases (6-58%), followed by deficits in long-term (4-58%) and short-term (4-37%) verbal memory. Visuospatial component of memory was studied less than verbal component, showing impairment of long-term retention of visual items (10-49%). COVID-19 severity in the acute stage was not systematically associated with poor memory performance. Verbal memory deficits were associated with anxiety and depression. The existing literature on objective memory assessment in long-COVID suggests further research is warranted to confirm memory dysfunction in association with epidemiological, pathological, and clinical factors, using both verbal and visuospatial tests, and exploring in deep long-term memory deficits.
