Cancer therapy agents have been used extensively as cytotoxic drugs against tissue or organ of a specific type of cancer. With the better understanding of molecular mechanisms underlying carcinogenesis and cellular events during cancer progression and metastasis, it is now possible to use targeted therapy for these molecular events. Targeted therapy is able to identify cancer patients with dissimilar genetic defects at cellular level for the same cancer type and consequently requires individualized approach for treatment...

With the widespread use of antiretroviral therapy and successful prevention of mother-to-child transmission the development of HIV-negative children with HIV-positive parents has become an important focus. There is considerable evidence that children's developmental risk is heightened because a parental HIV-diagnosis is associated with a range of potential problems such as depression, stigma and financial difficulties. Up to a third of children in sub-Saharan Africa (SSA) are cared for by an HIV-positive parent or caregiver...

OBJECTIVES: Posterior cruciate ligament (PCL) injuries are relatively common injuries associated with athletic activities and high-energy trauma. Posterolateral corner (PLC) injuries frequently accompany injury to the PCL. Diagnosis can be challenging and requires a comprehensive history and physical examination. Patients frequently report vague, nonspecific symptoms and the mechanism of injury is often useful in localizing injured structures. Two of the more common mechanisms for PCL injury include a direct blow to the proximal anterior tibia with the knee flexed, as well as a significant knee hyperextension injury...

The prognosis of patients receiving home mechanical ventilation is very heterogeneous and depends on the underlying disease, the degree of respiratory dependency and the comorbidities. Due to the severe chronic diseases, the initiation of a long-term NIV must be done during an inpatient treatment. Two recently published randomized controlled trials using more aggressive forms of NPPV targeted at normalizing hypercapnic PaCO2 values, showed improved long term survival also in patients with an underlying diagnosis of COPD...

Suicide remains a clear, present and increasing public health problem, despite being a potentially preventable tragedy. Its incidence is particularly high in people with overt or un(der)diagnosed psychiatric disorders. Objective and precise identification of individuals at risk, ways of monitoring response to treatments and novel preventive therapeutics need to be discovered, employed and widely deployed. We sought to investigate whether blood gene expression biomarkers for suicide (that is, a 'liquid biopsy' approach) can be identified that are more universal in nature, working across psychiatric diagnoses and genders, using larger cohorts than in previous studies...

Gang Chen, Xiaoyan Guo
Major depressive disorder, or depression, becomes a serious public health problem globally. As current mainstream conventional antidepressants have limitations in unsatisfied response and remission rate, late onset of efficacy and side effects, increasing attention has been drawn to traditional Chinese medicine (TCM), in which mixture of herbs is commonly prescribed after the clinicians make pattern identification for diagnosis. Here, the principle of herbal formulation for TCM (Chinese herbal medicine, CHM) on depression as well as some clinical outcome research is briefly introduced...

Early use of mechanical circulatory support, e.g. veno-arterial extracorporeal membrane oxygenation (ECMO) or left ventricular unloading by microaxial pump in refractory cardiogenic shock is recommended in current guidelines. Development of acquired von Willebrand Syndrome (AVWS) in patients with left ventricular assist devices (LVADs) and ECMO has been reported. There is an increasing number of patients treated with the Impella® CP microaxial pump for left ventricular unloading. However, the prevalence of AVWS in these high risk patients is unknown and needs to be determined...

OBJECTIVE: Persistence of leukemic cells after induction therapy has been shown to correlate with poor survival in acute myeloid leukemia (AML). In this study we tested if human mesenchymal stromal cells (hMSC) have protective effects on leukemic cells undergoing chemotherapy. METHODS: Persistent disease was used as marker to identify cases with therapy resistant leukemic cells in 95 AML patients. Immunophenotyping, cell cycle and apoptosis assays were assessed by flow-cytometry...

A 49-year-old Japanese man with worsening dyspnea was admitted with the diagnosis of new-onset heart failure (HF). His HF symptoms improved with standard treatment, but his left ventricular ejection fraction (LVEF) 21% remained unchanged. After he was discharged, he was diagnosed with severe sleep-disordered breathing (SDB). Continuous positive airway pressure (CPAP) therapy was introduced. Seven months later, his cardiac function had greatly improved (LVEF 50%). We report this case of a HF patient with SDB whose cardiac function greatly improved by CPAP therapy, and we discuss the pathophysiologic mechanisms of successful cardiac "reverse remodeling" in this case...

The neurological complications of AIDS (neuroAIDS) during the infection of human immunodeficiency virus (HIV) are symptomized by non-specific, multifaceted neurological conditions and therefore, defining a specific diagnosis/treatment mechanism(s) for this neuro-complexity at the molecular level remains elusive. Using an in silico based integrated gene network analysis we discovered that HIV infection shares convergent gene networks with each of twelve neurological disorders selected in this study. Importantly, a common gene network was identified among HIV infection, Alzheimer's disease, Parkinson's disease, multiple sclerosis, and age macular degeneration...

BACKGROUND: Despite significant advances in diagnosis and therapy, the rate of survival of patients with oral cancers still remains poor as an appropriate treatment has not been found yet, due to side effects of chemo/radiotherapy. AIM: This study aimed to identify molecular mechanisms of cell death of oral cancer cells caused by treatment with a nonselective Cox-2 inhibitor in combination with a low-dose chemotherapeutic drug. METHODS: Squamous cell carcinoma (SCC) cells SCC9 and SCC25 were subjected to mono- and combination therapy with nimesulide and cisplatin...

Supernumerary teeth are teeth that are present in addition to normal teeth. Although several hypotheses and some molecular signalling pathways explain the formation of supernumerary teeth, but their exact disease pathogenesis is unknown. To study the molecular mechanisms of supernumerary tooth-related syndrome (Gardner syndrome), a deeper understanding of the aetiology of supernumerary teeth and the associated syndrome is needed, with the goal of inhibiting disease inheritance via prenatal diagnosis. We recruited a Chinese family with Gardner syndrome...

This narrative review presents current aspects of diagnosis, epidemiology, aetiology and therapy of Premenstrual Dysphoric Disorder (PMDD). PMDD is characterised by emotional, physical and behavioral changes during the premenstrual phase of the menstrual cycle associated with clinically significant distress and marked impairment of psychosocial functioning. Due to its cardinal symptoms (e. g. marked affect lability and irritability), its specific cycle-dependent course and high symptom-specific stability, PMDD has been outlined as a new diagnostic category in the chapter on depressive disorders in the fifth edition of the "Diagnostic and Statistical Handbook of Mental Disorders"...

Osteosarcoma (OS) is a bone malignancy with high incidence. The underlying molecular mechanisms that are associated with the development of OS need further investigation. In this study, we showed that SLC34A2, a member of the solute carrier gene family, was significantly downregulated in OS patients and cell lines. Overexpression of SLC34A2 inhibited the proliferation, migration, and invasion of OS cells. Mechanistically, we found that SLC34A2 interacted with PTEN, and inactivated the PI3K/AKT signaling pathway...

BACKGROUND: Diagnosis of pneumonia in ventilated patients is challenging due to the lack of specific and definitive clinical symptoms, laboratory data or radiological abnormalities. METHODS: Based on quantitative tracheal aspirate (QTA) results, three groups of patients were compared: <10(5) cfu/ml, ≥10(5) cfu/ml and <10(6) cfu/ml, and ≥10(6) cfu/ml. We recorded demographic variables, underlying diseases and severity of illness at ICU admission...

Infective endocarditis is a rare disease associated with high morbidity and mortality. As a result, early diagnosis and prompt antibiotic treatment with or without surgical intervention is crucial in the management of such condition.We report a case of missed infective endocarditis of the aortic valve. The patient underwent mechanical aortic valve replacement, with the native valve being sent for histopathological examination. On re-admission 16 months later, he presented with syncope, shortness of breathing and complete heart block...

A previously healthy 21-year-old young woman presented with worsening dyspnoea and haemoptysis. Imaging was suggestive of widespread pulmonary haemorrhage. There was no other organ system involvement in particular no evidence of renal involvement. Raised antimyeloperoxidase titres allowed diagnosis of isolated diffuse alveolar haemorrhage (DAH) secondary to microscopic polyangiitis (MPA). The patient rapidly deteriorated with worsening respiratory failure despite invasive mechanical ventilation and required extracorporeal membrane oxygenation (ECMO)...

Cardiovascular disease is the leading cause of morbidity and mortality in developed countries. Stroke is associated with a marked disability burden and has a major economic impact; this is especially true for carotid artery stroke. Major advances in primary and secondary prevention during the last few decades have helped to tackle this public health problem. However, better knowledge of the physiopathology of stroke and its underlying genetic mechanisms is needed to improve diagnosis and therapy. miRNAs are an important, recently identified class of post-transcriptional regulators of gene expression and are known to be involved in cerebrovascular disease...
