Review
BACKGROUND
Wernicke's encephalopathy (WE) is a serious neurological disorder that is underdiagnosed. Despite limited clinical guidelines, the standard use of intravenous (IV) thiamine is underutilized and remains an area of research deserving much attention.
OBJECTIVES
We conducted a systematic review using Medline, Embase, and CENTRAL databases to identify and summarize the literature on IV thiamine treatment in WE. Human studies with WE patients who received ≥100 mg of thiamine IV met inclusion criteria. Randomized controlled trials, cross-sectional studies, and case reports were included.
RESULTS
A total of 27 studies were included: 20 case reports, five retrospective studies, one prospective study and one randomized control trial. Of the case reports, 11 (55%) cases were female, and the average age of all cases was 45 years (SD = 15). The other seven studies included 688 patients; the average age was 52 years (SD = 9), and 266 (38.7%) were female. Among the case reports, neurological and clinical findings were used to diagnose WE in 16 (80%) cases. MRI was utilized to diagnose 15 (75%) cases. 500 mg IV thiamine TID was reported in 12 case reports (60%). 18 (90%) of case reports had partial or complete resolution of symptoms following IV thiamine.
CONCLUSION
IV thiamine can alleviate neurological symptoms, cognitive dysfunction, and brain imaging lesions associated with WE. We found key limitations in the evidence for IV thiamine and diagnostic standards for WE. Future targeted research should establish clear diagnostic and treatment guidelines for WE to prevent this serious condition from being underdiagnosed or undertreated.

BACKGROUND
Autosomal dominant mutations of the gene can cause two epileptic disorders: benign familial neonatal seizures (BFNS) and developmental epileptic encephalopathy (DEE). This systematic review aims to identify the best reported therapy for these patients, relating to phenotype, neurodevelopmental outcome, and an eventual correlation between phenotype and genotype.
METHODS
We searched on PubMed using the search terms "" AND "therapy" and "" AND "treatment"; we found 304 articles. Of these, 29 met our criteria. We collected the data from 194 patients. All 29 articles were retrospective studies.
RESULTS
In all, 104 patients were classified as DEE and 90 as BFNS. After treatment began, 95% of BFNS patients became seizure free, whereas the seizures stopped only in 73% of those with DEE. Phenobarbital and sodium channel blockers were the most used treatment in BFNS. Most of the DEE patients (95%) needed polytherapy for seizure control and even that did not prevent subsequent developmental impairment (77%).Missense mutations were discovered in 96% of DEE patients; these were less common in BFNS (50%), followed by large deletion (16%), truncation (16%), splice donor site (10%), and frameshift (7%).
CONCLUSION
Phenobarbital or carbamazepine appears to be the most effective antiseizure medication for children with a "benign" variant. On the contrary, polytherapy is often needed for DEE patients, even if it does not seem to improve neurological outcomes. In DEE patients, most mutations were located in S4 and S6 helix, which could serve as a potential target for the development of more specific treatment in the future.

Meta-Analysis Review
BACKGROUND
The role of neoadjuvant epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI) targeted therapy for EGFR-mutated non-small cell lung cancer (NSCLC) is unclear. Previous studies have shown that EGFR-TKIs have excellent anti-tumor activity. However, almost all studies on neoadjuvant EGFR-TKI treatment for EGFR-mutated NSCLC have been non-randomized controlled trials with small sample sizes and different methods of statistical analysis, which may lead to a lack of valid metrics to assess the feasibility and safety of neoadjuvant EGFR-TKI treatment. This meta-analysis aimed to assess the efficacy and safety of neoadjuvant EGFR-TKI treatment for NSCLC patients with EGFR mutations.
METHODS
Relevant studies were systematically searched in PubMed, Embase, and Web of Science databases. Results including objective response rate (ORR), complete resection rate (R0), downstaging rate, pathological complete response (PCR), major pathological response (MPR), progression-free survival (PFS), overall survival (OS), and adverse events (AEs) were used for further analysis.
RESULTS
This meta-analysis ultimately included 11 studies involving 344 patients with EGFR-positive mutations in NSCLC. In terms of tumor response, the pooled ORR was 57% (95% CI: 42%-73%), and in the Osimertinib subgroup, the pooled ORR was 80% (95% CI: 63%-98%). Analysis of studies that reported a downstaging rate showed the pooled downstaging rate of 41% (95% CI: 9%-74%) and the pooled downstaging rate of 74% (95% CI: 22%-100%) in the Osimertinib subgroup. In terms of surgical outcomes, the pooled pCR rate was 3% (95% CI: 0%-7%), the pooled MPR rate was 11% (95% CI: 6%-17%), and the pooled R0 resection rate was 91% (95% CI: 85%-95%). The most common adverse events associated with neoadjuvant therapy were rash and diarrhea. The pooled incidence of any grade of rash was 47.1% (95% CI: 25.4%-69.3%), and the pooled incidence of grade ≥ 3 rash was 0.6% (95% CI: 0.0%-2.5%). The pooled incidence of diarrhea of any grade was 28.8% (95% CI: 14.4%-45.4%), with the pooled incidence of grade ≥ 3 diarrhea of 0.2% (95% CI: 0.0%-1.6%). The pooled incidence of ≥ grade 3 adverse events was significantly lower.
CONCLUSIONS
Our meta-analysis confirmed the efficacy and safety of neoadjuvant EGFR-TKIs for the treatment of NSCLC patients with EGFR-positive mutations and that third-generation EGFR-TKIs were superior to first- and second-generation EGFR-TKIs in terms of shrinking tumor volume and lowering tumor stage; however, future large-scale and multicenter randomized controlled trials are needed to confirm this conclusion.

Review
Cutaneous field cancerization in dermatology describes the anatomic region of photodamaged skin with actinic keratoses (AKs) or cutaneous squamous cell carcinoma (cSCC) that is surrounded by cellular atypia, forming a dysplastic field. The concept of field cancerization is especially relevant in dermatology, as actinic keratoses and the surrounding dysplastic region can progress to carcinomas, necessitating the treatment of the field. Recent research has focused on field-directed therapy using topical agents. This study aims to systematically review randomized controlled trials on topical treatments for actinic keratosis field cancerization, following the PRISMA guidelines. Clinical recommendations were based on the Oxford Centre for Evidence-Based Medicine. We identified 20 original randomized controlled trials for topical cutaneous field therapy. 0.5% 5-Fluorouracil/salicylic acid and 0.5% 5-fluorouracil received a clinical recommendation grade of A, while diclofenac sodium received a clinical recommendation grade of B. Calcipotriol/5-fluorouracil, Imiquimod, sunscreen combination therapies, and tirbanibulin received a recommendation grade of C. This review provides a framework for clinicians when considering topical treatments for patients with field cancerization.

Meta-Analysis Review
OBJECTIVE
This study aimed to explore the efficacy and safety of small-molecule antivirals for treating coronavirus disease 2019 (COVID-19).
METHODS
Seven databases were searched from their inception to 01 June 2023. The risk of bias in randomised controlled trials and retrospective studies was evaluated individually using the Cochrane risk-of-bias tool and Newcastle Ottawa Scale.
RESULTS
In total, 160 studies involving 933 409 COVID-19 patients were evaluated. Compared with placebo or standard of care, proxalutamide demonstrated remarkable efficacy in reducing mortality rates, hospitalisation rates, serious adverse events, and the need for mechanical ventilation. Furthermore, it significantly enhanced both the rate of clinical improvement and expedited the duration of clinical recovery when compared with control groups. In patients with mild-to-moderate COVID-19, proxalutamide exhibited the above advantages, except for mortality reduction. Triazavirin was the most effective treatment for reducing the time required for viral clearance and improving the discharge rate. Leritrelvir and VV116 were ranked first in terms of enhancing the viral clearance rate on days 7 and 14, respectively. Molnupiravir was the most effective treatment for reducing the need for oxygen support. Overall, these findings remained consistent across the various subgroups.
CONCLUSIONS
A thorough evaluation of effectiveness, applicable to both mild-to-moderate and unstratified populations, highlights the specific advantages of proxalutamide, nirmatrelvir/ritonavir, triazavirin, azvudine, molnupiravir, and VV116 in combating COVID-19. Additional clinical data are required to confirm the efficacy and safety of simnotrelvir/ritonavir and leritrelvir. The safety profiles of these antivirals were deemed acceptable.

Meta-Analysis Review
BACKGROUND
Heart failure is a pathophysiological condition where decreased cardiac output is observed subsequent to any structural deformity or cessation of normal function. Thiamine deficiency is one of the risk factors responsible for causing HF; other risk factors include hypertension, smoking, and obesity.
OBJECTIVE
We conducted a systemic review and meta-analysis of RCTs to scrutinize whether the heart failure patients would benefit from thiamine supplementation or not when compared to placebo.
METHODS
We selected only those double-arm randomized controlled trials (RCTs) which included participants presenting with symptomatic heart failure. We excluded all the articles published in languages other than English Language. Furthermore, all the studies other than RCTs were also omitted. Articles yielded from the electronic search were exported to EndNote Reference Library software to remove any duplicates. Analyses were done using the Review manager 5.4 tool. Mean values and standard deviations were retrieved for the continuous outcomes given as raw data.
RESULTS
The 6 RCTs selected for the statistical analysis consisted of 298 participants (158 in the intervention group, 140 in the placebo group). The outcomes resulted to be non-significant with LVEF p-value= 0.08, NT-pro BNP p-value= 0.94, LVEDV p-value= 0.53, 6MWT p-value=0.59, mortality p-value= 0.61, hospitalization p-value= 0.53 and dyspnea p-value= 0.77. Heart rate is the only significant outcome with a p-value=0.04.
CONCLUSION
To conclude, except for heart rate, thiamine supplementation had no effect on the outcomes of heart failure patients.

IMPORTANCE
A 2019 review for the US Preventive Services Task Force (USPSTF) found oral preexposure prophylaxis (PrEP) associated with decreased HIV infection risk vs placebo or no PrEP in adults at increased HIV acquisition risk. Newer PrEP regimens are available.
OBJECTIVE
To update the 2019 review on PrEP, to inform the USPSTF.
DATA SOURCES
Ovid MEDLINE, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, and Embase (January 2018 to May 16, 2022); surveillance through March 24, 2023.
STUDY SELECTION
Randomized clinical trials of PrEP vs placebo or no PrEP or newer vs older PrEP regimens and diagnostic accuracy studies of instruments for predicting incident HIV infection.
DATA EXTRACTION AND SYNTHESIS
Dual review of titles and abstracts, full-text articles, study quality, and data abstraction. Data were pooled using the DerSimonian and Laird random-effects model.
MAIN OUTCOMES AND MEASURES
HIV acquisition, mortality, and harms; and diagnostic test accuracy.
RESULTS
Thirty-two studies were included in the review (20 randomized clinical trials [N = 36 543] and 12 studies of diagnostic accuracy [N = 5 544 500]). Eleven trials in the 2019 review found oral PrEP associated with decreased HIV infection risk vs placebo or no PrEP (n = 18 172; relative risk [RR], 0.46 [95% CI, 0.33-0.66]). Higher adherence was associated with greater efficacy. One new trial (n = 5335) found oral tenofovir alafenamide/emtricitabine (TAF/FTC) to be noninferior to tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) in men who have sex with men (RR, 0.47 [95% CI, 0.19-1.14]). Two new trials found long-acting injectable cabotegravir associated with decreased risk of HIV infection vs oral TDF/FTC (RR, 0.33 [95% CI, 0.18-0.62] in cisgender men who have sex with men and transgender women [n = 4490] and RR, 0.11 [95% CI, 0.04-0.31] in cisgender women [n = 3178]). Discrimination of instruments for predicting incident HIV infection was moderate in men who have sex with men (5 studies; n = 25 488) and moderate to high in general populations of persons without HIV (2 studies; n = 5 477 291).
CONCLUSIONS AND RELEVANCE
In adults at increased HIV acquisition risk, oral PrEP was associated with decreased risk of acquiring HIV infection compared with placebo or no PrEP. Oral TAF/FTC was noninferior to oral TDF/FTC, and injectable cabotegravir reduced the risk of HIV infection compared with oral TDF/FTC in the populations studied.

Meta-Analysis
Comparison between different neoadjuvant chemotherapy regimens and local therapy alone for bladder cancer: a systematic review and network meta-analysis of oncologic outcomes.
PURPOSE
The present systematic review and network meta-analysis (NMA) compared the current different neoadjuvant chemotherapy (NAC) regimes for bladder cancer patients to rank them.
METHODS
We used the Bayesian approach in NMA of six different therapy regimens cisplatin, cisplatin/doxorubicin, (gemcitabine/cisplatin) GC, cisplatin/methotrexate, methotrexate, cisplatin, and vinblastine (MCV) and (MVAC) compared to locoregional treatment.
RESULTS
Fifteen studies comprised 4276 patients who met the eligibility criteria. Six different regimes were not significantly associated with a lower likelihood of overall mortality rate compared to local treatment alone. In progression-free survival (PFS) rates, cisplatin, GC, cisplatin/methotrexate, MCV and MVAC were not significantly associated with a higher likelihood of PFS rate compared to locoregional treatment alone. In local control outcome, MCV, MVAC, GC and cisplatin/methotrexate were not significantly associated with a higher likelihood of local control rate versus locoregional treatment alone. Nevertheless, based on the analyses of the treatment ranking according to SUCRA, it was highly likely that MVAC with high certainty of results appeared as the most effective approach in terms of mortality, PFS and local control rates. GC and cisplatin/doxorubicin with low certainty of results was found to be the best second options.
CONCLUSION
No significant differences were observed in mortality, progression-free survival and local control rates before and after adjusting the type of definitive treatment in any of the six study arms. However, MVAC was found to be the most effective regimen with high certainty, while cisplatin alone and cisplatin/methotrexate should not be recommended as a neoadjuvant chemotherapy regime.

Review
BACKGROUNDS AND AIMS
Hidradenitis suppurativa (HS) is a challenging skin disease with an underlying inflammatory process. Substantial progress has been made in our understanding of HS over the last few years, with the advancement of novel treatment approaches. The current systematic review aims to evaluate the safety and efficacy of Janus kinase (JAK) inhibitors and spleen tyrosine kinase (Syk) inhibitors in treating HS.
METHOD
A thorough systematic search was performed on PubMed/Medline, Web of Science, and Ovid Embase databases up to September 23th, 2023. Clinical studies published in English were included.
RESULTS
Our search yielded ten articles with a total of 165 patients treated with four types of JAK inhibitors (upadacitinib, povorcitinib, tofacitinib, and baricitinib) and one Syk inhibitor (fostamatinib). Upadacitinib, povorcitinib, and tofacitinib improved clinical outcomes, with a significant reduction in hidradenitis suppurativa clinical response (HiSCR) and abscess and inflammatory nodule count (AN count) during the treatment period. Also, these drugs are well tolerated in most HS patients with minimal adverse events (AEs). Moreover, baricitinib depicted an amelioration in signs and symptoms of HS in one case report. Also, fostamatinib exhibited favorable tolerability throughout a 12-week in moderate-to-severe HS patients. The remarkable clinical improvement, as assessed through HiSCR and hidradenitis suppurativa severity (IHS4), corresponded closely with serological indicators of inflammation following fostamatinib administration was achieved.
CONCLUSION
JAK and Syk inhibitors are potentially efficacious in managing moderate-to-severe HS since the proinflammatory cytokines are mediated by JAK and Syk signaling pathways. However, further research with a more rigorous examination is mandatory to evaluate such medication's long-term safety and efficacy.

Meta-Analysis
BACKGROUND
Guidelines show that for metastatic colorectal cancer (mCRC), a combination of three-drug regimens, fluorouracil, leucovorin, and oxaliplatin and bevacizumab (BVZ), is one of the first-line standard therapies. BVZ is generally well tolerated; however, it is associated with infrequent, life-threatening side effects such as severe hypertension (HTN) (5%-18%), Grade ≥3 arterial thromboembolism (ATE) (2.6%), Grade ≥3 hemorrhagic events (1.2%-4.6%), and gastrointestinal perforation (0.3%-2.4%). This meta-analysis aims to evaluate the additive risk of BVZ-induced severe HTN and thromboembolism when BVZ is combined with a standard chemotherapy regime in patients with mCRC.
METHODS
Our search was conducted from January 29, 2022, to February 22, 2022, through databases of PubMed, clinicaltrial.gov, EMBASE, Web of Science, and Cochrane Library. Data analysis from randomized controlled trials (RCTs) and clinical trials was conducted using Review Manager V.5.4, comparing BVZ-chemotherapy to chemotherapy only, focusing on cardiovascular AE such as HTN and arterial and venous thromboembolism.
RESULTS
The analysis from 26 clinical trials and RCTs showed that the odds of HTN were about four times higher, and ATE subgroup analysis of 11 studies showed over two times higher odds of ATE in patients being treated with BVZ compared to the chemotherapy-only group.
CONCLUSION
BVZ, when added to the standard chemotherapy regimen for mCRC, was associated with higher odds of developing HTN and thromboembolism, specifically ATE, than the chemotherapy-only group. Our findings are significant as they provide vital information in analyzing the risk-benefit ratio of adding BVZ to the standard chemotherapy regime in patients with mCRC, especially in patients with vascular comorbidities.
