Tissue diagnosis of suspected lung cancer: selecting between bronchoscopy, transthoracic needle aspiration, and resectional biopsy.

In pursuing a tissue diagnosis of a suspected lung cancer, there is a range of procedures to choose from. The principal goals are ideally to diagnose and pathologically stage the patient's lung cancer at the same time, preferably by using the safest, least invasive, and least costly tests. If there is clinical or radiographic evidence of extrapulmonary spread of disease, including supraclavicular N3 nodal involvement or a malignant pleural effusion, then radiology-guided or open biopsy will confirm tumor cell type and stage the patient as unresectable. For patients with symptoms, such as incre

Effect of NeuroSAFE-guided RARP versus standard RARP on erectile function and urinary continence in patients with localised prostate cancer (NeuroSAFE PROOF): a multicentre, patient-blinded, randomised, controlled phase 3 trial.

BACKGROUND: Sparing the periprostatic neurovascular bundles during robot-assisted radical prostatectomy (RARP) improves postoperative erectile function and early urinary continence recovery. The NeuroSAFE technique, a standardised frozen section analysis, enables accurate real-time detection of positive surgical margins during nerve-sparing, increasing the likelihood of successful nerve preservation. However, the impact of the technique on patient outcomes remains uncertain. We aimed to assess the effect of NeuroSAFE-guided RARP versus standard RARP on erectile function and urinary continence.

Cumulative live birth rate and neonatal outcomes after early rescue ICSI: a propensity score matching analysis.

STUDY QUESTION: Is early rescue ICSI (E-RICSI) an effective and safe technique compared to conventional ICSI? SUMMARY ANSWER: Despite the higher multi-pronucleus (PN) rate compared to conventional ICSI, E-RICSI did not add extra risks to clinical and neonatal outcomes. WHAT IS KNOWN ALREADY: Based on the finding that the second polar body was released in 80% of fertilized oocytes by 4 h after exposure to spermatozoa and in ∼90% of fertilized oocytes by 6 h, E-RICSI brings forward the timing of rescue ICSI to 6 h after initial insemination, and effectively prevents oocyte aging and embryo-ute

Haematopoietic transplant potential of unrelated and related cord blood: the first six years of the EUROCORD/NETCORD Bank Germany.

To date, human umbilical cord blood (CB) has been employed successfully in well over 1000 allogeneic (unrelated and sibling) stem cell transplantations. Because of primary limitations in volume and cell numbers, over 90% of these transplantations were performed in children. Therefore requests for well standardised cord blood units of high quality are now increasing constantly. Examination and standardisation of unrelated and related cord blood stem cell preparations and banking as well as their biological characterisation was already initiated in Düsseldorf in 1992. Hitherto a total of 3236 CB

Obstetric and perinatal outcomes following programmed compared to natural frozen-thawed embryo transfer cycles: a systematic review and meta-analysis.

STUDY QUESTION: Is there an association between the different endometrial preparation protocols for frozen embryo transfer (FET) and obstetric and perinatal outcomes? SUMMARY ANSWER: Programmed FET protocols were associated with a significantly higher risk of hypertensive disorders of pregnancy (HDP), pre-eclampsia (PE), post-partum hemorrhage (PPH) and cesarean section (CS) when compared with natural FET protocols. WHAT IS KNOWN ALREADY: An important and growing source of concern regarding the use of FET on a wide spectrum of women, is represented by its association with obstetric and perin

Spontaneous uterine rupture after myomectomy in patients during pregnancy: Clinical cases in a single university center.

Uterine rupture is an infrequent yet sometimes fatal complication of a subsequent vaginal birth attempt following a previous uterine surgery. We have chosen to write about spontaneous uterine ruptures following myomectomy due to the scarcity of data on this subject, stemming from the limited number of reported cases. Furthermore, with the increasing trend of advanced maternal age, there is a growing cohort of pregnant women with a history of myomectomy, thereby presenting a timely opportunity to examine this phenomenon in greater depth. A total of 28 studies reporting pregnancies after prior m

Natural versus artificial cycle for endometrial preparation in ovulatory women undergoing frozen-thawed embryo transfer: a randomised controlled trial.

STUDY QUESTION: Does a natural cycle result in higher clinical pregnancy rates (CPR) with foetal heartbeat compared to an artificial cycle for frozen-thawed embryo transfer (FET) preparation in ovulatory women? SUMMARY ANSWER: The CPR with foetal heartbeat did not differ between natural and artificial cycles in ovulatory women undergoing FET. WHAT IS KNOWN ALREADY: Several protocols for endometrial preparation have been developed for the increasing number of FET cycles in reproductive medicine. In natural cycle FET (NC-FET), spontaneous ovulation is used to time the embryo thawing and transf

Nucleic acid and antigen detection tests for leptospirosis.

BACKGROUND: Early diagnosis of leptospirosis may contribute to the effectiveness of antimicrobial therapy and early outbreak recognition. Nucleic acid and antigen detection tests have the potential for early diagnosis of leptospirosis. With this systematic review, we assessed the sensitivity and specificity of nucleic acid and antigen detection tests. OBJECTIVES: To determine the diagnostic test accuracy of nucleic acid and antigen detection tests for the diagnosis of human symptomatic leptospirosis. SEARCH METHODS: We searched electronic databases including MEDLINE, Embase, the Cochrane Lib

Conception methods and perinatal outcomes among women with kidney disorders: an Australian population-based cohort study.

STUDY QUESTION: Do conception methods and related pregnancy outcomes differ between women with and without kidney disease? SUMMARY ANSWER: In this cohort, 3.3% of births among women with kidney disorders were conceived using ART, 1.9% were conceived following IUI and ovulation induction (OI), and 94.8% were conceived spontaneously; however, women with kidney disorders consistently experienced higher risks of adverse pregnancy outcomes than those without, regardless of conception method. WHAT IS KNOWN ALREADY: Kidney disorders can impair fertility and pregnancy outcomes, but population‑level

Reduction in minipubertal gonadotropin levels alters reproductive lifespan and ovarian follicular loss in female mice.

STUDY QUESTION: What is the effect of attenuating the physiological hypergonadotropic activity encountered at minipuberty on female reproductive function in a mouse model? SUMMARY ANSWER: Decreasing the surge of gonadotropins at minipuberty extended reproductive lifespan, coinciding with alterations in neuroendocrine and ovarian aging. WHAT IS KNOWN ALREADY: Minipuberty is characterized by the tremendous activation of the gonadotrope axis, as evidenced by elevated levels of gonadotropins regulating folliculogenesis and the synthesis of ovarian hormones, but its role in fertility remains uncl

Surgery for Locally Advanced Pancreatic Cancer: Oncological Landmarks for Venous and Arterial Reconstruction.

BACKGROUND: According to the National Comprehensive Cancer Network (NCCN) guidelines, pancreatic cancer is classified as borderline resectable (BR-PC) on the basis of three criteria: (1) anatomical-the involvement of major vessels such as the celiac axis, hepatic artery (HA), superior mesenteric artery (SMA), or the mesenterico-portal venous axis; (2) biological-an elevated CA19-9 level exceeding 500 kU/L; and (3) conditional-patient unfitness for surgery due to general health status. The extensive involvement of major vessels is classified as locally advanced pancreatic cancer (LAPC). In such

STUDY QUESTION: What were the utilization, effectiveness and safety of practices in assisted reproductive technologies (ART) globally in 2014 and what global trends could be observed? SUMMARY ANSWER: The estimated total number of ART cycles conducted in 76 participating countries in 2014 was 1.93 million representing ∼66% of global activity, with 5-year trends including an increase in success rates and proportion of frozen embryo transfer (FET) cycles, improvement in cumulative live birth rates per aspiration, a continued increase in single embryo transfer (SET) and thus a reduction in multip

Ovarian stimulation with follitropin delta for in vitro fertilization: a multicentre, randomized, assessor-blind comparison with follitropin alfa using conventional dosing regimens (ADAPT-1 trial).

STUDY QUESTION: How do ovarian responses using conventional dosing for follitropin delta 15 µg/day compare with follitropin alfa 225 IU/day in women undergoing ovarian stimulation? SUMMARY ANSWER: The ADAPT-1 trial demonstrates similar ovarian responses with follitropin delta 15 µg/day and follitropin alfa 225 IU/day starting doses in a conventional dosing regimen. WHAT IS KNOWN ALREADY: Follitropin delta, a recombinant FSH (rFSH), is currently approved for ovarian stimulation using an individualized fixed daily dose based on serum anti-Müllerian hormone (AMH) and bodyweight (maximum 12 µg/d

Factor X deficiency: An overlooked cause of bleeding in the newborn.

Inherited factor X (FX) deficiency is a rare autosomal recessive bleeding disorder, presenting with various bleeding manifestations ranging from nonspecific bruising to life-threatening intracranial hemorrhage. It is often misdiagnosed as hemorrhagic disease of the newborn. It is characterized by prolonged prothrombin time, as well as activated partial thromboplastin time, and needs FX level assay for definitive diagnosis. Here, we describe a case of a newborn with FX deficiency who presented with frank umbilical stump bleeding.

Advances in MALDI Mass Spectrometry Imaging Single Cell and Tissues.
