Wellens syndrome in the small girl along with heart vasculitis.
Forest and Funnel plots were obtained, and a P-value of less then 0.05 was considered statistically significant. A total of 567 articles were screened, and we selected three meta-analyses with a total of 40 studies conducted over a period of 14 years. In our umbrella review, a total of 8,419 GC patients with an average PD-L1 positivity of 39% were analyzed. We found that PD-L1 positivity in GC patients is associated with poor prognosis (pooled HR =1.44, 95% CI 1.24-1.68, P less then 0.00001) having higher mortality reducing the chances of overall survival (OS). However, there are no significant differences in PD-L1 expression among different lymph node (LN) metastases (OR=1.31, 95% CI 0.98-1.74, P=0.07) and tumor, node, and metastasis (TNM) stages (OR=1.13, 95% CI 0.80-1.58, P=0.50). read more Early identification of PD-L1 expression may help tailor cost-effective and targeted immunotherapy among GC patients. More research is needed to further understand how PD-L1 affects LN metastasis and tumor invasion.Penetrating facial trauma can be a life-threatening condition, especially due to its impact on the airway. In a facial trauma, there is a distortion in the basic anatomy of the affected, making it a particularly difficult situation for managing the airway. Challenging intubation scenarios have been widely explored in the literature; however, difficult to ventilate situations have been undermined. We describe a case of a 35-year-old female who presented with a history of animal attack on the face. The extent of penetrating facial trauma warranted the need to secure the airway. Preserving spontaneous breathing and using an oral endotracheal tube for oxygenation saved the airway manager from cannot intubate and cannot oxygenate situation in a facial trauma patient. Difficult to mask ventilate while arranging for a definitive airway can be more pressing and challenging for the emergency physician. It also jeopardizes the patient's life, whose survival may only depend on acquiring the patency of the airway. Facial trauma patients may be conscious and spontaneously breathing, leading to the missed or delayed intervention in the airway; hence, prompt assessment and management of the airway in all facial trauma are of utmost importance.Hand-foot-and-mouth disease (HFMD) is a viral infection frequently encountered in the pediatric age group. Common culprits in such manifestations are coxsackievirus A16 and human enterovirus 71. The patient presents febrile with erythematous papulovesicular exanthems in the mouth, palms, and soles. HFMD is self-limiting in nature with a rare-complication rate. Onychomadesis is proximal nail separation while Beau's lines are whitish transverse lines and considered a rare complication of HFMD. Both allude to halted nail-matrix proliferation, and the pathophysiology behind such manifestations is still not yet understood. It is hypothesized that the virus elicits an inflammatory process, inhibiting nail-matrix proliferation or immune-complexes depositing on nails creating an embolism. Onychomadesis and Beau's lines appear after four to eight weeks of HFMD disease resolution and persist for approximately 35 days. There are no serious sequelae of those manifestations, as the nail basement is still intact. We present a case of a seven-year-old Saudi male presenting with nail changes, mainly onychomadesis and Beau's lines, after 35 days of HFMD disease resolution. All causes of nail changes have been ruled out and diagnosis of onychomycosis and Beau's lines secondary to HFDM has been established.Drug-induced lupus erythematosus (DILE) is a syndrome that manifests with symptoms similar, but with less severity, to that of systemic lupus erythematosus (SLE). Many medications are reported to be involved in DILE; however, terbinafine (Lamisil) is not a well-known causative agent of this syndrome. In this case report, we present a 22-year-old male patient with no prior medical history presented with worsening fever, rash, joint pain, and weight loss a couple of weeks after starting terbinafine. He underwent an extensive workup which revealed worsening kidney function, proteinuria, and microscopic hematuria, for which he underwent a renal biopsy which revealed class IV lupus nephritis. He was treated with prednisone taper and immunosuppressants with subsequent resolution of his symptoms. Close monitoring for the development of DILE symptoms is recommended after starting terbinafine, especially in patients with a known personal or family history of SLE.Metastasis of pancreatic adenocarcinoma to the colon is a very rare condition that might be underdiagnosed and underreported in the literature. We report a very rare case of incidental findings of sigmoid metastasis secondary to pancreatic adenocarcinoma in a 60-year-old Saudi male, who is a non-smoker with a normal medical and surgical history. The patient presented to a primary care clinic with abdominal bloating and vague on/off abdominal pain for almost 1 year as well as unintentional weight loss without lower gastrointestinal (GI) symptoms. After the case was discussed in the multidisciplinary tumor board, the patient was started on systematic palliative chemotherapy. However, after receiving the first cycle, he started to deteriorate rapidly and succumbed to secondary cardiopulmonary arrest. Cases of synchronous metastasis of pancreatic adenocarcinoma to the colon might not be well known or common. However, a high index of suspicion and individualizing the workup tools may need to be used.Genetic studies on telomere length are important for understanding age-related diseases. Prior GWAS for leukocyte TL have been limited to European and Asian populations. Here, we report the first sequencing-based association study for TL across ancestrally-diverse individuals (European, African, Asian and Hispanic/Latino) from the NHLBI Trans-Omics for Precision Medicine (TOPMed) program. We used whole genome sequencing (WGS) of whole blood for variant genotype calling and the bioinformatic estimation of telomere length in n=109,122 individuals. We identified 59 sentinel variants (p-value less then 5×10-9) in 36 loci associated with telomere length, including 20 newly associated loci (13 were replicated in external datasets). There was little evidence of effect size heterogeneity across populations. Fine-mapping at OBFC1 indicated the independent signals colocalized with cell-type specific eQTLs for OBFC1 (STN1). Using a multi-variant gene-based approach, we identified two genes newly implicated in telomere length, DCLRE1B (SNM1B) and PARN. In PheWAS, we demonstrated our TL polygenic trait scores (PTS) were associated with increased risk of cancer-related phenotypes.65 year old male with preexisting Complex Regional Pain Syndrome (CRPS) in right dominant hand with sudden onset of right third and fourth digit trigger finger successfully treated with flexor tendon sheath corticosteroid and lidocaine injection resulting in long-term resolution of symptoms without causing widely believed aggravation of CRPS.Huge abdominal wall hernias after radiation therapy in the absence of any previous surgical incisions or trauma are rare and, to the best of our knowledge, have not previously been reported. we report a patient with a massive hernia caused by abdominal wall weakness resulting from childhood radiation therapy.
The management of advanced hepatocellular (HCC) has drastically changed in the past few years with approval of several first line and second line systemic therapies. In this review we present an overview of the recent progress in the treatment of advanced HCC and discuss future perspectives.

The phase 3 clinical trial IMBRAVE150 has recently shown the combination of an immune checkpoint inhibitor, atezolizumab, with an anti-angiogenic agent, bevacizumab, to be superior to sorafenib monotherapy for treatment-naive advanced HCC. Moreover, patients now have multiple options available in second-line therapy including targeted therapies like sorafenib, lenvatinib, regorafenib, cabozantinib, ramucirumab and immunotherapies like atezolizumab, and nivolumab either alone or combined with ipilimumab.

There has been tremendous recent progress in the management of advanced HCC. Combination therapy with atezolizumab-bevacizumab has recently become the standard first line of therapy for patients with advanced HCC. Additionally, immunotherapy agents are poised to play a significant role in the management of HCC either alone or in combination with molecular targeted therapies.

Although vaccination has started, the development of drugs to either alleviate or abolish symptoms of COVID-19 is still necessary. Here, four synthetic peptides were assayed regarding their ability to protect Vero E6 cells from SARS-CoV-2 infection and their toxicity to human cells and zebrafish embryos. All peptides had some ability to protect cells from infection by SARS-CoV-2 with the D614G mutation. Molecular docking predicted the ability of all peptides to interact with and induce conformational alterations in the spike protein containing the D614G mutation. PepKAA was the most effective peptide, by having the highest docking score regarding the spike protein and reducing the SARS-CoV-2 plaque number by 50% (EC50) at a concentration of 0.15 mg mL-1. Additionally, all peptides had no toxicity to three lines of human cells as well as to zebrafish larvae and embryos. Thus, these peptides have potential activity against SARS-CoV-2, making them promising to develop new drugs to inhibit cell infection by SARS-CoV-2.
Parkinson's disease (PD) has been described in dopamine brain level reductions. Conversely, several studies have shown that
parasite can increase the level of dopamine in an infected host. This study was conducted to assess the serum, cerebral dopamine levels, and downregulation of Parkinson's disease manifestations in mice with chronic toxoplasmosis.

PD induction was done by oral inoculation of rotenone into BALB/c mice. To induce the chronic infection, cysts of
Prugniaud strain (genotype II) were injected intraperitoneally into the mice. The rotarod test was used for the evaluation of functional motor disorders in experimental mice. The serum and cerebral dopamine levels of the mice were also measured by using high-performance liquid chromatography (HPLC) on consecutive periods (10 days).

Findings of the rotarod test showed the highest and lowest average of running duration belonged to the uninfected mice and PD mice, respectively. Remarkably, the running duration of infected mice with PD was higher than PD mice. As well, the level of serum and cerebral dopamine increased in mice with PD and toxoplasmosis in comparison with PD mice.

Increasing the serum and cerebral dopamine levels in mice infected with toxoplasmosis is related to the presence of the parasite. Moreover, the dopamine upregulation due to the infection is effective in the reduction of PD complications.
