These results are consistent with the hypothesis that inhalation of PCB may contribute to behavioral abnormalities in children.Two complementary small-molecule-DNA hybrid (SMDH) building blocks have been combined to form well-defined supramolecular cage dimers at DNA concentrations as high as 102 μM. This was made possible by combining a flexible small-molecule core and three DNA arms of moderate lengths ( less then 20 base pairs). These results were successfully modeled by coarse-grained molecular dynamics simulations, which also revealed that the formation of ill-defined networks in the case of longer DNA arms can be significantly biased by the presence of deep kinetic traps. Notably, melting point studies revealed that cooperative melting behavior can be used as a means to distinguish the relative propensities for dimer versus network formation from complementary flexible three-DNA-arm SMDH (fSMDH3) components sharp, enhanced melting transitions were observed for assemblies that result mostly in cage dimers, while no cooperative melting behavior was observed for assemblies that form ill-defined networks.Deforestation in the Brazilian Amazon has dropped substantially after a peak of over 27 thousand square kilometers in 2004. Starting in 2008, the Brazilian Ministry of the Environment has regularly published blacklists of critical districts with high annual forest loss. Farms in blacklisted districts face additional administrative hurdles to obtain authorization for clearing forests. In this paper we add to the existing literature on evaluating the Brazilian anti-deforestation policies by specifically quantifying the impact of blacklisting on deforestation. We first use spatial matching techniques using a set of covariates that includes official blacklisting criteria to identify control districts. We then explore the effect of blacklisting on change in deforestation in double difference regressions with panel data covering the period from 2002 to 2012. Multiple robustness checks are conducted including an analysis of potential causal mechanisms behind the success of the blacklist. We find that the blacklist has considerably reduced deforestation in the affected districts even after controlling for the potential mechanism effects of field-based enforcement, environmental registration campaigns, and rural credit.A 58-year-old woman presented with intermittent passage of bright red blood from the rectum, progressive fatigue, and dyspnea. Examination revealed telangiectasias on the labial mucosa and nail folds. Her mother was reported to have frequent epistaxis and similar skin lesions.Like other human anatomical systems, the mammary ducts and glands at the time of lactation adhere to a perfect fractal geometry - which is destroyed by breast cancer. Could a loss of fractal geometry of the blood supply to human tissue be an early step in oncogenesis?A 50-year-old man with a history of cardiomyopathy and progressive muscle weakness was admitted with cardiogenic shock. Electroencephalography showed total suppression of cerebral activity; ventilator support was withdrawn, and he died. An autopsy was performed.A 13-year-old boy presented with a 9-month history of episodic unilateral swelling of the face and oral pain. He reported having loose, nonbloody stools. Granulomatous inflammation consistent with Crohn's disease was found on histopathological examination.Although in textbooks asthma and chronic obstructive pulmonary disease (COPD) are viewed as distinct disorders, there is increasing awareness that many patients have features of both. This article reviews the asthma-COPD overlap syndrome.
The standard therapy for women with unexplained infertility is gonadotropin or clomiphene citrate. Ovarian stimulation with letrozole has been proposed to reduce multiple gestations while maintaining live birth rates.

We enrolled couples with unexplained infertility in a multicenter, randomized trial. Ovulatory women 18 to 40 years of age with at least one patent fallopian tube were randomly assigned to ovarian stimulation (up to four cycles) with gonadotropin (301 women), clomiphene (300), or letrozole (299). The primary outcome was the rate of multiple gestations among women with clinical pregnancies.

After treatment with gonadotropin, clomiphene, or letrozole, clinical pregnancies occurred in 35.5%, 28.3%, and 22.4% of cycles, and live birth in 32.2%, 23.3%, and 18.7%, respectively; pregnancy rates with letrozole were significantly lower than the rates with standard therapy (gonadotropin or clomiphene) (P=0.003) or gonadotropin alone (P<0.001) but not with clomiphene alone (P=0.10). Among ongoing tion with letrozole resulted in a significantly lower frequency of multiple gestation but also a lower frequency of live birth, as compared with gonadotropin but not as compared with clomiphene.

Three anatomical sites are commonly used to insert central venous catheters, but insertion at each site has the potential for major complications.

In this multicenter trial, we randomly assigned nontunneled central venous catheterization in patients in the adult intensive care unit (ICU) to the subclavian, jugular, or femoral vein (in a 111 ratio if all three insertion sites were suitable [three-choice scheme] and in a 11 ratio if two sites were suitable [two-choice scheme]). The primary outcome measure was a composite of catheter-related bloodstream infection and symptomatic deep-vein thrombosis.

A total of 3471 catheters were inserted in 3027 patients. In the three-choice comparison, there were 8, 20, and 22 primary outcome events in the subclavian, jugular, and femoral groups, respectively (1.5, 3.6, and 4.6 per 1000 catheter-days; P=0.02). In pairwise comparisons, the risk of the primary outcome was significantly higher in the femoral group than in the subclavian group (hazard ratio, 3.5; 95% confid.

What can investigators do to address the problem?With the Merit-Based Incentive Payment System, Medicare shifts from payment based on macroeconomic indicators to relying on physician- or group-level indicators of cost and quality--and could create a large fee differential between high- and low-performing physicians.Medicare's new payment system reflects the movement toward value-based payment, which is built on the view that we can contain costs only by eliminating fee-for-service payment. But there are important problems with this belief and the reforms it inspires.The practice of laparoscopic liver surgery has developed gradually, and most liver resections seem currently feasible and safe for selected patients in centers where surgeons are experienced both in liver surgery and in laparoscopic surgery. However, further studies would be required, especially for long-term oncological results and for major hepatectomy follow-up, before laparoscopic hepatectomy becomes a common alternative to open liver surgeries. Laparoscopic major hepatectomy is a recent technique, due to its significant complexity. In this review, we showed that patients undergoing laparoscopic hepatectomy for liver metastases experienced decreased rates of overall and major postoperative complications without any compromise on long-term outcomes compared to patients treated by open resection.
To summarize the literature on options of management of patients treated for locally advanced cervical cancers with a specific focus on resource-constrained settings where brachytherapy is not available.

A Medline search was performed to summarize studies about treatment approaches including neoadjuvant chemotherapy, primary surgery for bulky cervical cancer, and chemoradiation followed by surgery. Summaries are by treatment approaches that are relevant to resource-constrained settings.

There are a lack of studies performed on neoadjuvant chemotherapy in low-resource settings. Primary surgery followed by chemoradiation therapy for selected patients with bulky cervical cancer is a feasible option. The disadvantage is the potential increase in treatment complications. Chemoradiation without brachytherapy followed by surgery has been found to have equivalent outcomes and is associated with acceptable morbidity.

In resource-constrained settings where brachytherapy is not available, performing radical hysterectomy after chemoradiation therapy without brachytherapy has been shown to produce equivalent outcomes. It seems reasonable to adopt a modified therapeutic protocol of chemoradiation followed by extrafascial hysterectomy as an alternative treatment option in low-resource countries where brachytherapy is not readily available.

To report our institution's treatment techniques, disease outcomes, and complication rates after radiotherapy for the management of lymphoma involving the orbits.

We retrospectively reviewed the medical records of 44 patients curatively treated with radiotherapy for stage IAE (75%) or stage IIAE (25%) orbital lymphoma between 1969 and 2013. Median follow-up was 4.9 years. Thirty-eight patients (86%) had low-grade lymphoma and 6 (14%) had high-grade lymphoma. Radiation was delivered with either a wedge-pair (61%), single-anterior (34%), or anterior with bilateral wedges (5%) technique. The median radiation dose was 25.5 Gy (range, 15 to 47.5 Gy). Lens shielding was performed when possible. Cause-specific survival and freedom from distant relapse were calculated using the Kaplan-Meier method.

The 5-year local control rate was 98%. Control of disease in the orbit was achieved in all but 1 patient who developed an out-of-field recurrence after irradiation of a lacrimal tumor. The 5-year regional control rate was 91% (3 patients failed in the contralateral orbit and 1 patient failed in the ipsilateral parotid). Freedom from disease, cause-specific survival, and overall survival rates at 5 and 10 years were 70% and 55%, 89% and 89%, and 76% and 61%, respectively. Acute toxicity was minimal. Ten patients (23%) reported worsened vision following radiotherapy, and cataracts developed in 17 patients. Cataracts developed in 13 of 28 patients treated without lens shielding (46%) and 4 of 16 patients (25%) treated with lens shielding.

Radiotherapy is a safe and effective local treatment in the management of orbital lymphoma.

Snakebite envenoming (SBE) is a major problem in rural areas of West Africa (WA). Compared to other Neglected Tropical Diseases (NTD), the public health burden of SBE has not been well characterized. We estimated the impact of snakebite mortality and morbidity using the Disability Adjusted Life Years (DALYs) metrics for 16 countries in WA.

We used the reported annual number of SB deaths and mean age at time of SB and converted these into years of life lost (YLL). Similarly, the years of life lived with disability (YLD) were estimated by multiplying the number of amputations by the respective disability weight of 0.13.

In WA, the annual cases of SB mortality and amputations ranged from 24 (95% Confidence Interval 19-29) and 28 (17-48) respectively in Guinea-Bissau with the highest estimates of 1927 (1529-2333) and 2368 (1506-4043) respectively in Nigeria. We calculated that the annual DALYs associated with a SB death ranged from 1550 DALYs (95%CI 1227-1873 DALYs) in Guinea Bissau to 124,484 DALYs (95%CI 98,773-150,712 DALYs) in Nigeria.
