Efficacy and predictability of short dental implants (<8 mm): a critical appraisal of the recent literature.

PURPOSE This review of literature was conducted to evaluate the predictability of treatment outcomes with short dental implants (SDI), ie, implants shorter than 8 mm. MATERIALS AND METHODS The review included studies, published between January 1990 and July 2011, that (1) involved SDI (<8 mm) placed in human jaws, (2) had a minimum of 20 SDI in their analysis, (3) provided data on survival rates, and (4) reported a minimum observation period of at least 3 months after placement. RESULTS Forty-one studies fulfilled the above criteria; only 17 of these studies reported outcomes with microrough surface SDI. Six different lengths (4, 5, 6, 6.5, 7 and 7.5 mm) of microrough surface SDI with varying diameters (3.5 to 6 mm) were identified in the studies. A total of 1,828 microrough surface SDI were inserted and 45 failures were reported. Observation periods ranged from 3 months to 9 years. The reported survival rates for SDI ranged from 92.2% to 100%. From a total of 1,123 SDI inserted in specified jaw locations, failures were observed more often in the maxilla (n=297, failed=13) than in the mandible (n=826, failed=19). The review did not identify any correlation between implant diameter and survival for the microrough SDI. CONCLUSIONS Microrough surface short implants (6 to 7.5 mm) appear to provide favorable survival rates and, therefore, can be predictably employed for simplification of implant therapy in situations of reduced alveolar heights in the posterior jaw segments.
Anatomy of the posterolateral aspect of the goat knee

The purpose of this study was to determine the anatomy of the posterolateral aspect of the goat knee for future in vivo studies using a goat model to examine the natural history of posterolateral knee injuries. Twelve nonpaired, fresh‐frozen, adult goat knees were dissected to determine the anatomy of the posterolateral corner. The main posterolateral structures identified in the goat knee were the lateral collateral ligament, the popliteus muscle and tendon, popliteomeniscal fascicles, and the lateral gastrocnemius muscle. The lateral collateral ligament was extra‐articular and coursed from its proximal attachment, located posterior and proximal to the lateral epicondyle, to its distal attachment on the lateral aspect of the fused proximal tibiofibula. The popliteus muscle attached to the medial edge of the posterodistal tibia, traveled anterolaterally, became intra‐articular at its musculotendinous junction, and attached to the lateral femur just distal to the lateral epicondyle. Distinct popliteomeniscal fascicles attached the lateral meniscus to the popliteus muscle and tendon, and a fascial attachment from the musculotendinous junction of the popliteus muscle coursed to the lateral tibial plateau. This study provided information on the structures present in the posterolateral aspect of the goat knee and enhanced our understanding of their relationships to analogous structures in the human knee. This information is important to enable future development of potential models of the natural history of posterolateral knee injuries and also to test surgical techniques and the in vivo effects of these injuries on cruciate ligament reconstructions. © 2005 Orthopaedic Research Society.

Lifetime Major Depression is Associated With Coronary Heart Disease in Older Adults: Results From the National Epidemiologic Survey on Alcohol and Related Conditions

Objective: To examine the association between mood and anxiety disorders and coronary heart disease (CHD) in a nationally representative sample of older adults. Methods: Data from the National Epidemiologic Survey on Alcohol and Related Conditions were analyzed with 10,573 adults aged ≥60 years surveyed. Results: A total of 13.30% of older adults reported diagnoses of CHD. Age (odds ratio (OR) = 1.04), morbid obesity (OR = 1.60), hypertension (OR = 2.29), lifetime nicotine dependence (OR = 1.41), and lifetime drug use disorders (OR = 2.19) were all significantly related to CHD. Being female (OR = 0.73) relative to male and a lifetime social drinker (OR = 0.71) compared with alcohol abstainers decreased the odds of CHD. After controlling for these characteristics, the presence of a lifetime major depressive episode was significantly associated with increased risk of CHD (OR = 2.05), but the lifetime anxiety disorders assessed were not. The association between lifetime mood disorders and CHD was similar for both genders, and single versus multiple depressive episodes conferred equal risk of CHD. Conclusions: These data demonstrate that a lifetime major depressive episode increases the risk of CHD in older adults. CHD = coronary heart disease; NIAAA = National Institute on Alcohol Abuse and Alcoholism; NESARC = National Epidemiologic Survey on Alcohol and Related Conditions; AUDADIS = Alcohol Use Disorder and Associated Disabilities Interview Schedule; DSM-IV = Diagnostic and Statistical Manual of Mental Disorders—Fourth Edition; BMI = body mass index; OR = odds ratio; CI = confidence interval.
Evaluating the self-assessed support needs of women with breast cancer.

AIMS OF THE STUDY The first aim of the study was to identify the self-assessed support needs of women with breast cancer at various points of illness and, secondly, to establish if these needs formed clusters which could provide the basis for developing a standardized scale of needs for use by breast care teams in the evaluation of care. BACKGROUND It has been found that support given to women with breast cancer has a positive effect upon their reactions to the illness and may even prolong their survival. Given that breast cancer affects a large number of women it is obviously important that those affected receive, in addition to the best available medical treatment, the type of support that best meets their needs. This study aimed to provide information on the impact of breast cancer and the need for various types of support by examining women's own assessment of their needs at different stages of their illness. DESIGN AND METHODS A purposive sample of 12 women with a diagnosis of breast cancer was selected in one health authority in England, United Kingdom (UK). Women selected represented a wide age range (between 26 and 58), were married or in long-term cohabiting relationships and were at different points on the illness trajectory. Women were invited to take part in a semi-structured interview about their experiences of breast cancer. The data from these interviews were analysed using the software package Qualitative Solutions and Research, Nonnumerical Data Indexing, Searching and Theorizing (QSR*NUDIST). Following this content analysis, a questionnaire was formulated which divided statements into seven categories: diagnosis, treatment, support, femininity and body image, family and friends, information and after care, to be rated on a Likert scale ranging from "of no importance" to "extremely important". Questionnaire data were analysed by means of a one-way analysis of variance (for three independent variables) or t-test for two independent variables. Results. The questionnaire was sent to 971 women and achieved a response rate of 50.4%. The mean score for statements of need reached the level of point 4 on the Likert scale (important) with three exceptions: having professional help with family problems and domestic upheaval, coping with feelings of anger and dealing with the question "why me? " CONCLUSION With the above three exceptions, women experienced a high level of need associated with a diagnosis of breast cancer. Studies of this kind should enable resources to be targeted to areas of highest need.
Effects of level of feeding and ruminally undegraded protein on ruminal bacterial protein synthesis, escape of dietary protein, intestinal amino acid profile, and performance of dairy cows.

Six cannulated lactating cows were used in two replicated, concurrently run 3 x 3 Latin square experiment to study the interaction between level of feeding and diets differing in ruminally undegraded protein (RUP) on bacterial protein synthesis, ruminal escape of dietary protein, and flow of total and individual amino acids (AA) to the small intestine. Treatments consisted of three diets formulated to contain 69 g (HL), 53 g (HH), and 48 g (LL) of RUP per kilogram of DM, respectively. Measurements were made in early lactation, at high feeding level (19.3 kg DM/d), and repeated at late lactation (9.8 kg DM/d, low feeding level) with the same animals and diets. Decreasing feed intake increased (P < .05) the apparent digestibility of OM, NDF, and ADF in the rumen and the total tract, decreased (P < .05) ruminal liquid and particulate passage rate and total ruminal VFA concentration, and increased ruminal pH and ammonia concentration. Decreased level of intake reduced the (P < .05) efficiency of bacterial N synthesis (28.1 vs 23.7 g bacterial N/kg OM truly digested in the rumen) and decreased (P < .05) ruminal protein degradation rate measured with an in situ method. Duodenal flow of nonammonia nitrogen (NAN), and total AA were highest (P < .05) for the HL diet and lowest (P < .05) for the LL diet at the high feeding level. However, at the low feeding level, diet composition did not affect the amount of NAN or total AA passing to the small intestine. Diet HL increased the proportion of Met, His (P < .05), and Arg (P < .07) in the duodenal digesta at both feeding levels. When purines were used to calculate bacterial N synthesis, no differences between diets were detected. However, when diaminopimelic acid was used, highest bacterial N synthesis was detected for diet HH at the high feeding level. Diet HL supported the highest (P < .05) milk protein production at the high feeding level, and the highest (P < .05) milk protein content at the low feeding level. In conclusion, level of feeding and amount of RUP altered the amount and composition of AA presented to the cows.
Prostate cancer treatments and their side effects are associated with increased insomnia

Between 25% and 40% of prostate cancer patients report insomnia symptoms. Although a possible role of androgen deprivation therapy (ADT) and radiation therapy (RTH) and some of their side effects have been postulated, this issue has rarely been investigated. This study aimed to (1) compare the evolution of insomnia symptoms and somatic symptoms, which may affect sleep quality (i.e., hot flashes, night sweats, and urinary symptoms), in patients receiving combined ADT and RTH with that in patients receiving RTH only and (2) assess the mediating role of somatic symptoms in the relationship of ADT and RTH with insomnia symptoms.
Neurodegeneration Caused by Proteins with an Aberrant Carboxyl‐Terminus

In recent years, 2 groups of hereditary neurodegenerative diseases have been recognized in which different genetic defects lead to the accumulation of proteins that contain a carboxyl-terminus that is abnormal in length and primary sequence. In this paper, we review the current knowledge on the molecular basis of diseases from these 2 groups. The first group includes familial British and Danish dementias, in which the molecular genetic defect resides in the BRI2 gene located on chromosome 13. In this group, carboxyl-terminal proteolytic products of the mutant BRI2 proteins aggregate in the extracellular space of the brain and in blood vessels. The second group includes 2 recently described ferritinopathies, in which the molecular genetic defect resides in the ferritin light polypeptide gene located on chromosome 19. In this group, full-length ferritin polypeptides aggregate intracellularly. The study of these conditions has led to the discovery of the BRI2 gene and to the finding of an unsuspected role for ferritin in neurodegeneration. These diseases provide new models in which to study the relationship between abnormal protein aggregation, neuronal cell death, and dementia.
Direct and indirect effects of breast milk on the neurobehavioral and cognitive development of premature infants.

Eighty-six premature infants were tested to examine the effects of maternal breast milk on infant development. Infants were classified by breast-milk consumption during the hospitalization period (M = 57.4 days) into three groups: those receiving minimal (<25% of nutrition), intermediate (25-75%), and substantial (>75%) amounts of breast milk. Infants in the three groups were matched for birth weight, gestational age (GA), medical risk, and family demographics. At 37 weeks GA, mother-infant interaction was videotaped, maternal depression self-reported, and neurobehavioral maturation assessed by the Neonatal Behavior Assessment Seale (Brazelton, 1973). At 6 months corrected age, infants were tested with the Bayley II (Bayley, 1993). Infants receiving substantial amounts of breast milk showed better neurobehavioral profiles-in particular, motor maturity and range of state. These infants also were more alert during social interactions, and their mothers provided more affectionate touch. Higher maternal depression scores were associated with lower quantities of breast milk, longer latencies to the first breast-milk feeding, reduced maternal affectionate touch, and lower infant cognitive skills. Maternal affectionate touch moderated the relations between breast milk and cognitive development, with infants receiving a substantial amount of breast milk and frequent touch scoring the highest. In addition to its nutritional value, breast milk may be related to improved maternal mood and interactive behaviors, thereby indirectly contributing to development in premature infants.
Impact of different stent alloys on human vascular response to everolimus‐eluting stent: An optical coherence tomography study: The OCTEVEREST

New generation drug‐eluting stents (DES) incorporate thinner struts and novel alloys to improve clinical performance. Nevertheless, the impact of novel stent materials and designs on human vascular response to DES remains elusive. We sought to evaluate the in‐vivo coronary artery response to platinum‐chromium (PtCr) versus cobalt‐chromium (CoCr) stents featuring the same durable polymer and antiproliferative drug by optical coherence tomography (OCT).
GLP-1 receptor agonists have a sustained stimulatory effect on corticosterone release after chronic treatment

Objective Glucagon-like peptide 1 (GLP-1) receptor agonists are a new group of antidiabetic medications quickly gaining popularity. We aimed to examine behavioural and neuroendocrine changes following chronic treatment with GLP-1 receptor agonists in animal models. Methods The effects of chronic treatment with GLP-1 receptor agonists were determined on behavioural parameters [anxiety level in the light–dark compartment test, the motor activity in automated activity cages, immobility in the forced swimming test (FST)] and on corticosterone release in mice. The possible antidepressant effect of chronic liraglutide treatment was also studied in Flinders Sensitive Line (FSL) rats, a genetic model of depression. Results Two weeks of treatment with exenatide (10 µg /kg twice daily) or liraglutide (1200 µg/kg once daily) did not affect the anxiety level in a light–dark compartment test nor induce an antidepressant-like effect in the FST in mice. Moreover, chronic treatment with liraglutide had no effect on depression-related behaviour in FSL rats. Interestingly, hypolocomotion induced by the drugs in mice disappeared after chronic dosing. Both of the GLP-1 receptor agonists induced robust increases in corticosterone levels in mice under basal conditions as well as in the case of combination with swimming stress. Remarkably, exenatide was as potent a stimulator of corticosterone release after 2 weeks as after acute administration. Conclusions The increases in corticosterone release seen after acute exenatide or liraglutide treatment do not abate after 2 weeks of treatment demonstrating that tolerance does not develop towards this particular effect of GLP-1 agonists.
Serum Cholesterol and Intellectual Performance

Objective The current investigation sought to determine whether intellectual performance is related to serum lipid concentrations. Methods Subjects were 177 healthy, Caucasian adult males and females, aged 25 to 60 years, with widely varying total cholesterol concentrations. Crystallized intelligence was estimated from the Information and Vocabulary subtests of the Wechsler Adult Intelligence Scale, Revised (WAIS-R). Fluid intelligence was estimated from the WAIS-R Block Design subtest, and from a computerized version of the Letter Rotation test. Results Controlling for age, better performance on both Information and Vocabulary subtests was associated with lower total and low-density lipoprotein (LDL) cholesterol and triglyceride concentrations (r's = -.24 to -.35, p's<.005). In contrast, better performance on Block Design was correlated with higher total and LDL cholesterol (r's = .22 to .23, p's<.005). Letter rotation response latency was unrelated to serum lipids. Conclusion These opposing relationships between serum cholesterol and different dimensions of intellectual performance, on the one hand, may reflect the propensity of knowledgeable individuals to consume low fat diets, and on the other hand, suggest that serum cholesterol concentration may be a correlate of brain nutrients important to mental efficiency.
Regulation of DNA Damage Signaling and Cell Death Responses by Epstein-Barr Virus Latent Membrane Protein 1 (LMP1) and LMP2A in Nasopharyngeal Carcinoma Cells

ABSTRACT Nasopharyngeal carcinoma (NPC) is closely associated with latent Epstein-Barr virus (EBV) infection. Although EBV infection of preneoplastic epithelial cells is not immortalizing, EBV can modulate oncogenic and cell death mechanisms. The viral latent membrane proteins 1 (LMP1) and LMP2A are consistently expressed in NPC and can cooperate in bitransgenic mice expressed from the keratin-14 promoter to enhance carcinoma development in an epithelial chemical carcinogenesis model. In this study, LMP1 and LMP2A were coexpressed in the EBV-negative NPC cell line HK1 and examined for combined effects in response to genotoxic treatments. In response to DNA damage activation, LMP1 and LMP2A coexpression reduced γH2AX (S139) phosphorylation and caspase cleavage induced by a lower dose (5 μM) of the topoisomerase II inhibitor etoposide. Regulation of γH2AX occurred before the onset of caspase activation without modulation of other DNA damage signaling mediators, including ATM, Chk1, or Chk2, and additionally was suppressed by inducers of DNA single-strand breaks (SSBs) and replication stress. Despite reduced DNA damage repair signaling, LMP1-2A coexpressing cells recovered from cytotoxic doses of etoposide; however, LMP1 expression was sufficient for this effect. LMP1 and LMP2A coexpression did not enhance cell growth, with a moderate increase of cell motility to fibronectin. This study supports that LMP1 and LMP2A jointly regulate DNA repair signaling and cell death activation with no further enhancement in the growth properties of neoplastic cells. IMPORTANCE NPC is characterized by clonal EBV infection and accounts for >78,000 annual cancer cases with increased incidence in regions where EBV is endemic, such as southeast Asia. The latent proteins LMP1 and LMP2A coexpressed in NPC can individually enhance growth or survival properties in epithelial cells, but their combined effects and potential regulation of DNA repair and checkpoint mechanisms are relatively undetermined. In this study, LMP1-2A coexpression suppressed activation of the DNA damage response (DDR) protein γH2AX induced by selective genotoxins that promote DNA replication stress or SSBs. Expression of LMP1 was sufficient to recover cells, resulting in outgrowth of LMP1 and LMP1-2A-coexpressing cells and indicating distinct LMP1-dependent effects in the restoration of replicative potential. These findings demonstrate novel properties for LMP1 and LMP2A in the cooperative modulation of DDR and apoptotic signaling pathways, further implicating both proteins in the progression of NPC and epithelial malignancies.
A comprehensive study of the direct and indirect costs of adult asthma.

BACKGROUND Asthma is a common and costly health condition, but most estimates of its economic effect have relied on secondary sources with limited condition-specific detail. OBJECTIVE We sought to estimate the magnitude of direct and indirect costs of adult asthma from the perspective of society. METHODS We used cross-sectional survey data from an ongoing community-based panel study of 401 adults with asthma originally derived from random samples of northern California pulmonologists, allergist-immunologists, and family practitioners to assess health care use for asthma, to assess purchase of items to assist with asthma care, and to measure work and other productivity losses. Unit costs derived from public-use and proprietary data sources were then assigned to the survey items. RESULTS Total per-person annual costs of asthma averaged $4912 US dollars, with direct and indirect costs accounting for $3180 US dollars (65%) and $1732 US dollars (35%), respectively. The largest components within direct costs were pharmaceuticals ($1605 US dollars [50%]), hospital admissions ($463 US dollars[15%]), and non-emergency department ambulatory visits ($342 US dollars [11%]). Within indirect costs, total cessation of work accounted for $1062 US dollars (61%), and the loss of entire work days among those remaining employed accounted for another $486 US dollars (28%). Total per-person costs were $2646, $4530, and $12,813 US dollars for persons self-reporting mild, moderate, and severe asthma, respectively (P <.0001, 1-way ANOVA). CONCLUSION Asthma-related costs are substantial and are driven largely by pharmaceuticals and work loss.
Comparison of Intraocular Pressure During Corneal Flap Preparation Between a Femtosecond Laser and a Mechanical Microkeratome in Porcine Eyes

Purpose: To compare the increase in intraocular pressure (IOP) during corneal flap preparation in porcine eyes when using a femtosecond laser or a mechanical microkeratome. Setting: The present study was conducted at a university hospital and a private clinic. Methods: The vitreous IOP was directly measured with a cannula through the optic nerve in 24 porcine globes (n = 12 for each device). In the first procedure (worst-case procedure), the eye interface was lowered against the globe until abortion of the docking maneuver when using the IntraLase femtosecond laser (Abbott Medical Optics, Santa Ana, CA) or the suction ring was pressed very firmly against the globe when using the Amadeus microkeratome (Ziemer Ophthalmic Systems AG, Port, Switzerland). In the second procedure (regular procedure), a normal lamellar flap creation was performed using each of these devices. Results: During the worst-case procedure, a maximum IOP of 260 ± 53 mm Hg (mean ± SD) was reached with the IntraLase and 318 ± 59 mm Hg was reached with the Amadeus. During the regular procedure, the maximum IOP increased to 135 ± 16 mm Hg when using the IntraLase femtosecond laser and to 152 ± 24 mm Hg with the Amadeus microkeratome. Conclusions: In the worst-case procedure, the maximum IOP levels were lower in the IntraLase group. No significant difference in maximum IOP levels could be obtained during the regular procedure. The duration of the suction phase is longer when using the IntraLase femtosecond laser.
