ABSTRACT Based on studies of petrographic thin sections from core and cutting samples, the pre-Permian siliciclastics in four deep wells in southern Kuwait were found to be tight. Three of these wells are located on the crestal region of the Burgan Arch, and one on the Umm Gudair anticline. These clastics were encountered beneath a thin brick-red shale of unknown thickness, immediately below the pre-Khuff unconformity at the base of the Permian-Triassic Khuff Formation. The pre-Khuff clastics range in thickness from a few tens of feet to more than 4,000 ft, and overlie a Proterozoic argillite (Economic Basement). Based on Illite Age Analysis (IAA) of samples from cores, the depositional K-Ar age of the pre-Khuff clastics is estimated to be younger than 509 Ma (90 percent confidence interval: 544–481 Ma, i.e. Cambrian-Early Ordovician). The argillite was uplifted through the 300°C isotherm at about 611 Ma (90% confidence interval: 635-588 Ma, i.e Late Proterozoic); its deposition and metamorphism preceded this date. During the Paleozoic, the pre-Khuff clastics were buried to depths of 10,000–15,000 ft, but were subsequently uplifted in the Late Paleozoic. IAA diagenetic K-Ar ages of the Economic Basement (421 Ma; 90 percent confidence interval: 442-397 Ma; Late Ordovician-Early Devonian) and pre-Khuff clastics (369 Ma; 90 percent confidence interval: 404–337 Ma, i.e. Devonian-Early Carboniferous) indicate that by these times the pre-Khuff section was already deposited and undergoing burial diagenesis. The interpretation of gravity data indicates that in Paleozoic basinal regions (e.g. between the Burgan Arch and Umm Gudair Anticline), the Paleozoic sedimentary section is likely to be more complete and may exceed 10,000 ft in thickness.

OBJECTIVE: To determine whether heparin sodium, when added to fluids infused through a peripheral catheter, reduces some local catheter-related problems (i.e., phlebitis, catheter obstruction, and extravasation of fluid) and extends the catheter's useful life. DESIGN: Prospective, double-blind, placebo-controlled. SETTING: Internal medicine ward of a general hospital with 400 beds. PATIENTS: Eighty-one consecutive acute collaborating patients who had a venous catheter in the forearm, inserted by nurses with more than one year of professional experience. INTERVENTION: Heparin sodium 1000 units/mL or NaCl 0.9% was added to compatible infusion fluids just before they were given to the patients. The final concentration of heparin was 1 unit/mL. MEASUREMENTS: Length of time until catheters were removed and reasons for their removal. RESULTS: The heparin group had a lower rate of local catheter-related problems than the placebo group (34.3 vs. 61.5 percent, respectively, p<0.05; 95 percent confidence interval for the difference 4.3 to 50.1 percent). The catheter's mean life in the heparin group was longer than that of the placebo group (98.9 ± 55.2 vs. 66.2 ± 47.2 h, respectively, p<0.05; 95 percent confidence interval for the difference 9.15 to 56.25 h). This effect was mainly attributable to prevention of noninflammatory catheter-related problems (e.g., obstruction, extravasation) and to a delay in the appearance of phlebitis. CONCLUSIONS: Heparin sodium, when added to infusion fluids to a final concentration of 1 unit/mL, diminishes local intravenous catheter-related problems and extends the catheter's life.

Background: Resection of hepatocellular carcinoma is associated with high rates of morbidity and mortality. Since intensive nutritional support can reduce the catabolic response and improve protein synthesis and liver regeneration, we performed a prospective study to investigate whether perioperative nutritional support could improve outcome in patients undergoing hepatectomy for hepatocellular carcinoma.Methods: We studied 124 patients undergoing resection of hepatocellular carcinoma. Sixty-four patients (39 with cirrhosis, 18 with chronic active hepatitis, and 7 with no associated liver disease) were randomly assigned to receive perioperative intravenous nutritional support in addition to their oral diet, and 60 patients (33 with cirrhosis, 12 with chronic active hepatitis, and 15 with no associated liver disease) were randomly assigned to a control group. The perioperative nutritional therapy consisted of a solution enriched with 35 percent branched chain amino acids, dextrose, and lipid emulsion (50 percent medium-chain trigylcerides) given intravenously for 14 days perioperatively).Results: There was a reduction in the overall postoperative morbidity rate in the perioperative-nutrition group as compared with the control group (34 percent vs. 55 percent; relative risk, 0.66; 95 percent confidence interval, 0.45 to 0.96), predominantly because of fewer septic complications (17 percent vs. 37 percent; relative risk, 0.57; 95 percent confidence interval, 0.34 to 0.96). There were also a reduction in the requirement for diuretic agents to control ascites (25 percent vs. 50 percent; relative risk, 0.57; 95 percent confidence interval, 0.37 to 0.87), less weight loss after hepatectomy (median loss, 0 kg vs. 1.4 kg; P=0.01), and less deterioration of liver function as measured by the change in the rate of clearance of indocyanine green (–2.8 percent vs. –4.8 percent at 20 minutes, P=0.05). These benefits were seen predominantly in the patients with underlying cirrhosis who underwent major hepatechtomy. There were five deaths during hospitalization in the perioperativenutrition group, and nine in the control group (P not significant).Conclusions: Perioperative nutritional support can reduce complications after major hepatectomy for hepatocellular carcinoma associated with cirrhosis.

AbstractThe westward continuation of the Highland Border fault of Scotland (HBFZ) into Ireland is problematic. It is widely thought to follow a pronounced magnetic and gravity lineament, the Fair Head-Clew Bay Line (FCL). The advantage of this interpretation is that it places all the Ordovician ophiolitic complexes and associated sedimentary basins to the south of the FCL, which would represent the contact between Laurentia and the outboard terranes. Its main shortcomings are that both the deep structure and timing of strike-slip are different on the HBFZ and FCL. In Ireland the FCL is a north-dipping feature that can be traced to the Moho on BIRPS profiles, while the HBFZ has no such signature. Terrane amalgamation in western Ireland was completed by the late Ordovician, while in Scotland the Midland Valley terrane did not finally dock until the early Devonian. These considerations suggest that in western Ireland a branch of the HBFZ exists, which was active in post-Ordovician time and must lie south of Connemara. An examination of Irish geological, geophysical and image-processed magnetic data shows that a profound lineament can be traced from Antrim to Galway Bay (the Antrim–Galway Line). Stitching plutons date movement on it as pre-405 Ma. We propose that the Antrim–Galway Line represents the continuation of the Scottish HBFZ, while the FCL is a preserved Ordovician splay of the HBFZ system whose northdipping geometry is a product of Ordovician collapse of the orogen in western Ireland.

Time Gap

ABSTRACTSeveral specimens of myriapodous arthropods have been discovered at the early Carboniferous East Kirkton site near Bathgate, West Lothian, Scotland. None is particularly well preserved, but they are the earliest known Carboniferous myriapods, filling the time gap between the Old Red Sandstone of the early Devonian and the abundant myriapod faunas of the late Carboniferous (Pennsylvanian). One of the specimens, a milliped, provides the earliest evidence for both ozopores (repugnatorial gland openings) and spiracles. A second milliped specimen has some characteristics of the living Order Glomeridesmida, and hence of Enghoff's (1990) ‘ground plan’ of chilognathan millipeds. Aspects of these forms and a third suggest a novel early Carboniferous fauna clearly different from both earlier and later ones. The taxon name ‘Myriapoda’ should be abandoned, since it covers a group now recognised as paraphyletic. ‘Archipolypoda’ is probably synonymous with Order Euphoberiida, Class Diplopoda.

ABSTRACT Background Evidence supporting professionalism as a critical measure of competence in medical education is limited. In this case–control study, we investigated the association of disciplinary action against practicing physicians with prior unprofessional behavior in medical school. We also examined the specific types of behavior that are most predictive of disciplinary action against practicing physicians with unprofessional behavior in medical school. Methods The study included 235 graduates of three medical schools who were disciplined by one of 40 state medical boards between 1990 and 2003 (case physicians). The 469 control physicians were matched with the case physicians according to medical school and graduation year. Predictor variables from medical school included the presence or absence of narratives describing unprofessional behavior, grades, standardized-test scores, and demographic characteristics. Narratives were assigned an overall rating for unprofessional behavior. Those that met the threshold for unprofessional behavior were further classified among eight types of behavior and assigned a severity rating (moderate to severe). Results Disciplinary action by a medical board was strongly associated with prior unprofessional behavior in medical school (odds ratio, 3.0; 95 percent confidence interval, 1.9 to 4.8), for a population attributable risk of disciplinary action of 26 percent. The types of unprofessional behavior most strongly linked with disciplinary action were severe irresponsibility (odds ratio, 8.5; 95 percent confidence interval, 1.8 to 40.1) and severely diminished capacity for self-improvement (odds ratio, 3.1; 95 percent confidence interval, 1.2 to 8.2). Disciplinary action by a medical board was also associated with low scores on the Medical College Admission Test and poor grades in the first two years of medical school (one percent and seven percent population attributable risk, respectively), but the association with these variables was less strong than that with unprofessional behavior. Conclusions In this case–control study, disciplinary action among practicing physicians by medical boards was strongly associated with unprofessional behavior in medical school. Students with the strongest association were those who were described as irresponsible or as having diminished ability to improve their behavior. Professionalism should have a central role in medical academics and throughout one’s medical career.

Triple-negative breast cancer (TNBC) is a very variable disease, and molecular subtyping may enable more precise diagnosis and treatment. Our earlier work categorized TNBCs into four subgroups, each with its own set of potential treatment targets. To assess the effectiveness of these targets, we performed the study, a phase Ib/II subtyping-based and genomic biomarker-guided umbrella study. Patients with refractory metastatic TNBC were enrolled and assigned to one of seven arms: (A) pyrotinib plus capecitabine, (B) androgen receptor inhibitor plus CDK4/6 inhibitor, (C) anti-PD-1 plus nab-paclitaxel, (D) PARP inhibitor plus nab-paclitaxel, (E) and (F) anti-VEGFR plus nab-paclitaxel, or (G The major outcome measure was the rate of objective response (ORR). We included 69 patients with resistant metastatic TNBC who had previously received a median of three lines of treatment (range, 1-8). Twenty-nine (29.0 percent, 95 percent confidence interval (CI): 18.7 percent -41.2 percent ) of the 69 intention-to-treat (ITT) patients obtained an objective response. Our findings indicated that immunotherapy (arm C) had the greatest ORR (52.6 percent, 95 percent confidence interval [CI]: 28.9 percent -75.6 percent ) in the ITT group. Arm E had a good ORR (26.1 percent, 95 percent CI: 10.2 percent -48.4 percent in the ITT group), but was associated with a higher prevalence of severe adverse events (grade 3). Somatic mutations in TOP2A and CD8 immunohistochemistry score may be able to predict immunotherapy response in patients with TNBC classified as immunomodulatory. In conclusion, the phase Ib/II study demonstrated the therapeutic benefit of subtyping-based targeted therapy for refractory metastatic TNBC.
