Exposure to anti-infective drugs and the risk of preterm birth – individual drugs analysis. Manuscript published in the British Journal of Obstetritics and Gynaecology 2011 Oct;118(11):1374-82. Study population: Analyses were done on prospectively collected data of 63338 pregnant women that met eligibility criteria for the study (8192 cases and 55146 controls). A control was defined as a pregnancy resulting in a baby’s weight adjusted for gestational age and gender ≥10th percentile. As the burden is so significant, the detection and management of risk factors are crucial (6). Despite the very frequent usage of anti-infective drugs during pregnancy (9), there is still some controversy regarding the risks and benefits of such usage on the pregnant woman and her unborn child. Only a few classes of antimicrobial compounds have been shown to be fetus-safe when used during gestation, such as older beta-lactams. Since randomized trials on therapeutic harm are rarely ethical and practical during pregnancy, this issue would be better addressed by large population-based studies derived from evidence-based data. The Med-Echo database records acute care hospitalization data for all Quebec residents; it also records gestational age for planned abortions, miscarriages and deliveries. Gestational age is defined from the first day of the last menstrual period to the end of pregnancy, and confirmed by ultrasound around the 18th-20th week of gestation. The following demographic information is included: for the mother (date of birth, age, marital status, mother-tongue, place of birth, area of residence, number of live births, number of deliveries), for the father (date of birth, age, mother-tongue, place of birth); and for the baby (gender, type of delivery, weight, gestational age, order in the family, date of birth). The Registry has often been used to assess the risks and benefits of drug use during pregnancy (20,21). This study was approved by the Sainte-Justine Hospital Ethics Committee and by the Commission d’accès à l’information du Québec, the provincial agency that grants authorization for the use of linked administrative databases. If a woman had more than one pregnancy between 1998 and 2003, the first pregnancy meeting eligibility criteria was considered for analysis. A control was defined as a pregnancy resulting with a baby’s weight adjusted for gestational age and gender ≥10th percentile. Exposure to Anti-infective Drugs In all analyses, the exposure to anti-infective drugs was treated dichotomously. The exposure window was the pregnancy’s second (>14 to ≤ 26 weeks of gestational age) or third trimester (>26 weeks of gestational age). To be considered as exposed in a particular trimester, pregnant women had to have filled at least one prescription for an anti-infective drug in the corresponding trimester, or if the duration of a prescription overlapped the corresponding trimester. For the first analysis, overall exposure to at least one anti-infective drug (all combined) was compared to no exposure (reference category). Women counted for these variables during the last year before pregnancy are not likely to be the same women with a code for this variable during pregnancy. Statistical Analysis Descriptive statistics, Student t-tests and Chi-square test were used to compare cases and controls. Univariate and multivariate unconditional logistic regression models were built, adjusting for important confounders and proxy variables for socioeconomic, health services utilization and co-morbidities. Characteristics of the Study Population A total of 63 338 pregnant women within the registry met the eligibility criteria and were included in this study. The standard used for this study is the population-based Canadian reference for birth weight for gestational age (22). These drugs are the first-line agent for the treatment of urinary tract infections among women allergic to penicillins (27). Although some methodological flaws in this study, the authors put their findings in perspective with a very strong biological rational: a placental microvascular disease may arise from a maternal folate-homocysteine metabolic defect caused by an exposure to these drugs. However, our findings bring attention to unsuspicious non-antibiotic properties of old and well known anti-infective drugs and the clinical implications of these properties. In fact, there is increasing evidence that some other anti- infectives, may show different biological actions in the modulation of the inflammatory pathway, apoptosis inhibition, regulation of bone metabolism and angiogenesis (30). Nitrofurantoin is one of the oldest urinary anti-infective drugs available and it can be safely used by pregnant woman in any given trimester (29). Nevertheless, increasing nitrofurantoin resistance complicates the choice of empiric regimens.
Several well-recognized plants that contain hallucinogenic or psychoactive substances (the compound names are given in parentheses) include Banisteriopsis caapi (Spruce ex Griseb donepezil 5 mg with visa symptoms detached retina. Several of these plants are also used as drugs due to their desired pharmaco- logical activities cheap 10 mg donepezil with amex medicine 3605 v, and some of the constituents of these plants have been devel- oped into modern medicines quality 10 mg donepezil medicine 027 pill, either in the natural form or as lead compounds subjected to optimization by synthetic organic chemistry [5 order donepezil 5 mg without prescription symptoms nausea dizziness, 6]. The Aztec nobility used to consume bitter beverages containing raw cocoa beans (Theo- broma cacao L. Nowadays, tea, coffee, and cocoa are important commodities and their consumption has spread world- wide. The active components of these stimulants are methylated xanthine de- rivatives, namely caffeine, theophylline, and theobromine, which are the main constituents of coffee, tea, and cocoa, respectively . Chapter 1 Drug Discovery from Plants 3 The most popular inebriants in society today are wine, beer, and liquor made from the fermentation of fruits and cereals. The intoxicating ingredient of these drinks is ethanol, a by-product of bacterial fermentation, rather than secondary plant metabolites. Recent studies have shown that a low to moder- ate consumption of red wine is associated with reduction of mortality due to cardiovascular disease and cancer . This health beneft has been suggested to be due to the presence of resveratrol, a hydroxylated stilbenoid found in the skin of grapes . Kava is not normally consumed in this manner in the Western world, but has gained popularity as a botanical dietary supplement to ease the symptoms of stress, anxiety, and depression . A study has shown that the anxiolytic activ- ity of kava extract may be mediated in part by the kavalactone, dihydrokavain . The consumption of kava has been associated with liver toxicity, although this is somewhat controversial. Recently, a study has shown that the alkaloid pipermethystine, found mostly in the leaves and stems of Piper methysticum, may be responsible for this toxicity . Before the realization that pharmacologically active compounds present in medicinal plants are responsible for their effcacy, the “doctrine of signatures” was often used to identify plants for treating diseases. For example, golden- rod with a yellow hue was used to cure jaundice, red-colored herbs were used to treat blood diseases, liverworts were used for liver diseases, pileworts for hemorrhoids, and toothworts for toothache . In 1805, morphine became the frst pharmacologically active compound to be isolated in pure form from a plant, although its structure was not elucidated until 1923 . The 19th cen- tury marked the isolation of numerous alkaloids from plants (species in paren- theses) used as drugs, namely, atropine (Atropa belladonna), caffeine (Coffea arabica), cocaine (Erythroxylum coca), ephedrine (Ephedra species), morphine and codeine (Papaver somniferum), pilocarpine (Pilocarpus jaborandi Holmes), physostigmine (Physostigma venenosum), quinine (Cinchona cordifolia Mutis ex Humb. Following these discoveries, bioactive secondary metabolites from plants were later utilized more widely as medicines, both in their original and modifed forms [5, 6]. Kinghorn The correlation between the ethnomedical usage of medicinal plants and modern medicines discovered from those plants has been studied by Fabri- cant and Farnsworth . Based on their analysis, 88 single chemical entities isolated from 72 medicinal plants have been introduced into modern therapy, many of which have the same or a similar therapeutic purpose as their origi- nal ethnomedical use . Some of these plant-derived compounds, such as atropine (anticholinergic), codeine (cough suppressant), colchicine (antigout), ephedrine (bronchodilator), morphine (analgesic), pilocarpine (parasympa- thomimetic), and physostigmine (cholinesterase inhibitor) are still being used widely as single-agent or combination formulations in prescription drugs . The importance of plants in modern medicine has been discussed in recent reviews and reports [19–22]. Other than the direct usage of plant second- ary metabolites in their original forms as drugs, these compounds can also be used as drug precursors, templates for synthetic modifcation, and pharmaco- logical probes, all of which will be discussed briefy in turn in this section. The semisynthetic approach is usually used to resolve the shortage of supply due to the low yield of compounds from plants and/or the high cost of total synthesis. For compounds with complex structures and many chiral centers, protracted methods may be needed for their synthesis, and thus these methods would not be feasible economically. The fol- lowing examples indicate that some secondary metabolites from plants are use- ful drug precursors, although they are not necessarily pharmacologically active in their original naturally occurring forms. Even though this compound can be produced by total synthesis, this has proven to be ineffcient in affording large quantities of paclitaxel [24, 25]. Since 2002, Bristol-Myers Squibb has produced paclitaxel using a plant cell culture method, which will be mentioned in section 1. Diosgenin (3), a steroidal sapogenin obtained from the tubers of various Dioscorea species that grow in Mexico and Central America, can be converted chemically in several steps into progesterone (4), a hormone that can be used as a female oral contraceptive . Originally, progesterone was isolated from sow ovaries with a very low yield (20 mg from 625 kg of ovaries), and later was synthesized from cholesterol with very low effciency . Progesterone is also a key intermediate for the production of cortisone (5), an important anti-infam- matory drug. Progesterone can be converted into 11α-hydroxyprogesterone (6) by microbial hydroxylation at C-11, followed by chemical reactions, to produce 6 A. Until now, diosgenin (3) is still an important starting ma- terial for the production of various steroid hormones. Oseltamivir phosphate (7, Tamifu) is an orally active neuraminidase inhibi- tor developed for the treatment and prophylaxis of infuenza viruses A and B [34, 35].

Mean serum tacrolimus levels among adherent patients shown to be higher than those considered non-adherent. Table 1 displays baseline characteristics, which were similar between all three groups. Results: All patients received methylprednisolone on induction and prednisone as maintenance therapy. Three patients used prednisone for 3 months only, and 1 patient used for 106 months. The patients who had more frequent and severe acute rejection episodes remained on prednisone for a longer time (pα=0. Cyclosporine was used on 115 patients (39%), with mycophenolate association on 51 (17,2%). However, longer use of corticosteroids and higher levels of immunosuppressive therapy used to treat acute rejection episodes seems to carry on an increased risk of recurrence.

Immunosuppression without steroids could help to improve the control of these risk factors. Objective: to compare the effect on cardiovascular risk factors after liver transplantation of a steroid-free immunosuppression regimen with tacrolimus + mycophenolate mofetil (group A) versus conventional immunosuppression with tacrolimus + steroids (group B).

Next generic donepezil 5 mg without prescription medications for gout, breathing is assessed by listening to the chest for the presence of equal bilateral breath sounds and by observing the symmetry of chest wall expansion buy 10 mg donepezil otc medicine you cannot take with grapefruit. The unstable patient with clinical signs of pneumothorax or tension pneumothorax should be treated with immediate needle decompression followed by placement of a chest tube order donepezil 5 mg with mastercard medicine 7 day box. Finally buy donepezil 10 mg on line symptoms you have cancer, circulation is assessed via the vital signs and by palpation of bilateral femoral, radial, or pedal pulses. Next, the patient’s ability to follow commands should be evaluated and an overall assessment of his/her level of functioning should be made. This consists of assigning a score on the Glasgow coma scale, ranging from 3 to 15 (see also Table I–1 in Section I). Based on the capability of your hospital and trauma or emergency services, bed- side ultrasound can be incorporated into the initial evaluation of the trauma patient. In the presence of severe, obvious injuries, it is appropriate to start the examina- tion at the affected sites. However, one must be cautious and diligent to complete a thorough physical examination to preclude missing any less obvious but equally important or potentially life-threatening injuries. In addition to being ejected from a vehicle involved in a collision at high speed, and therefore at risk for multi- system injuries secondary to a high kinetic energy transfer, the patient was found 1 hour following the incident. The risk for hypothermia and a diminished ability to respond to hemorrhagic shock is great. In this situation, the loss of blood volume decreases venous return, cardiac filling pressures, and cardiac output. End-organ perfusion is subsequently decreased as blood flow is preferentially preserved to the brain and heart. Instead, anaerobic metabolism dominates, leading to an accumulation of pyruvate that is converted to lactate. Shock is initially compensated by control mechanisms that return cardiac output and arterial pressure back to normal levels. Within seconds, baroreceptors and che- moreceptors elicit powerful sympathetic stimulation that vasoconstricts arterioles and increases heart rate and cardiac contractility. After minutes to hours, angio- tensin constricts the peripheral arteries while vasopressin constricts the veins to maintain arterial pressures and improve blood return to the heart. Angiotensin and vasopressin also increase water retention, thereby improving cardiac filling pres- sures. Locally, vascular control preferentially dilates vessels around the hypoxic tis- sues to increase blood flow to injured areas. The normal manifestations of shock do not apply to pregnant women, athletes, and individuals with altered autonomic nervous systems (older patients, those taking β-blockers). This leads to cardiac depression from decreased coronary blood flow, and, in turn, further decreases arterial pressure. The result is a feedback loop that becomes a vicious cycle toward uncontrolled deterioration. Inadequate blood flow to the nervous system eventually results in complete inactivation of sympathetic stimulation. In the microvasculature, low blood flow causes the blood to sludge, amplifying the inadequate delivery of oxy- gen to the tissues. This ischemia results in increased microvascular permeability, and large quantities of fluid and protein move from the intravascular space to the extra- vascular compartment, which exacerbates the already decreased intravascular volume. The systemic inflammatory response syndrome caused by severe injury and shock may progress to multiorgan failure. Cells lose the ability to maintain electrolyte balance, metabolize glucose, maintain mitochondrial activity, and prevent lysosomal release of hydrolases. Resuscitation during this progressive stage of tissue ischemia can cause reperfusion injury from the burst of oxygen-free radicals. Finally, the patient enters the irreversible stage of shock, and any therapeutic efforts become futile. Despite transiently elevated arterial pressures and cardiac out- put, the body is unable to recover, and death becomes inevitable. Pathophysiology and Stages of Hemorrhagic Shock Hemorrhagic shock is the most common cause of death in trauma patients aside from traumatic brain injury. A high level of suspicion for hemorrhage and hemorrhagic shock should dominate evaluation of a trauma patient, especially as vital signs may not become abnormal until a significant amount of hemorrhage has occurred. Additional clinical signs that indicate hemorrhagic shock include skin pallor/coolness, delayed capillary refill, weak distal pulses, and anxiety. In this patient, the possibility of bleeding should be assessed in five areas: (1) external bleeding (eg, scalp/extremity lacerations); (2) thorax (eg, hemothorax, aortic injury); (3) peritoneal cavity (eg, solid organ lacerations, large vessel injury); (4) pelvis/ retroperitoneum (eg, pelvic fracture); and (5) soft-tissue compartments (eg, long- bone fractures). Chest roentgeno- grams can identify a hemothorax and potential mediastinal bleeding. Fractures are not only associ- ated with blood loss from the bone and adjacent soft tissue, but their presence indicates significant energy transfer (often referred to as a significant mechanism of injury) and should increase the clinical suspicion for intra-abdominal and retroperitoneal bleeding. Typically, tibial or humeral fractures can be associated with 750 mL of blood loss (1. Pelvic fractures may result in even more blood loss—up to several liters can be lost into a retroperitoneal hematoma.
She has none of the findings suggestive of a more complicated process (Table 25–1) donepezil 10 mg without prescription treatment innovations. Her symptoms are likely caused by paralysis of the seventh cranial nerve cheap 10mg donepezil with amex medicine to induce labor, which is mainly a motor nerve supplying all the ipsilateral muscles of facial expression buy cheap donepezil 10mg medicine zalim lotion. The drooping of the right corner of the mouth represents paralysis of the orbicularis oris muscle buy donepezil 5mg otc symptoms kidney disease. Tearing of the right eye (epiphora) occurs because paralysis of the orbicularis oculi muscle prevents closure of the eyelids and causes the lacrimal duct opening to sag away from the conjunctiva. The inability to wrinkle the fore- head is a result of paralysis of the frontalis muscle. Affected individuals will often have the Bell phenomenon upon attempted closure of the eyelids, the eye on the paralyzed side rolls upward. It also has a small sensory component which conveys taste sensation from the anterior two-thirds of the tongue and cutaneous impulses from the anterior wall of the external auditory meatus. A complete interruption of the facial nerve at the stylomastoid foramen paralyzes all the muscles of the face on the affected side. Taste sensation is intact because the lesion is beyond the site where the chorda tympani has separated from the main trunk of the facial nerve. If the geniculate ganglion or the motor root proximal to it is involved, lacrimation and salivation may be reduced. Although the most common cause of facial paralysis is Bell palsy, this is a diagnosis of exclusion. Other causes of nuclear or peripheral facial nerve palsy include Lyme disease, tumors of the temporal bone (carotid body, cholesteatoma, dermoid), Ramsey Hunt syndrome (herpes zoster of the geniculate ganglion), and acoustic neuromas. All forms of peripheral facial nerve palsy must be distinguished from the supranu- clear type. In the latter, the frontalis and orbicularis oculi muscles are spared because the innervation of the upper facial muscles is bilateral and that of the lower facial muscles is mainly contralateral. In other words, if the patient has drooping of the mouth but is able to wrinkle his or her forehead normally, an intracranial process should be suspected. With supranuclear lesions, there may also be a dissociation of emotional and voluntary facial movements. Because Bell palsy is a diagnosis of exclusion, a very careful history and physical examination are critical to detect any other neurological abnormalities. The onset of Bell palsy is abrupt, and symptoms can progress from weakness to complete paralysis over a week. Associated symptoms may include pain behind the ear, ipsilateral loss of taste sensation, decreased or overflow tearing, and hyperacusis. The patient may complain of heaviness and numbness on the affected side of the face; however, no sensory loss is demonstrable. The presence of incomplete paralysis in the first week is the most favorable prognostic sign. If the presentation is atypical or there is no improvement at 6 months, laboratory studies, imaging studies (eg, computed tomog- raphy, magnetic resonance imaging), or motor-nerve conduction studies should be considered. While awake, he or she should apply artificial tears to the affected eye every hour. Medical therapy should be started as soon as possible but can be considered for up to 1 week after the onset of symptoms. Although treatment regimens are controversial, most experts recommend the use of corticosteroids. Thus prednisone 1 mg/kg/d can be given orally for 7 to 10 days (with or without a taper). Because some studies implicated herpes simplex virus as a causative agent of Bell palsy, antivirals were routinely incorporated into the treatment regimen. However, further studies have shown conflicting results regarding the efficacy of antiviral therapy. If physicians choose to prescribe antiviral agents, valacyclovir and famciclovir are favored due to their less frequent dosing and greater bioavailability. These agents do cost sub- stantially more than acyclovir, which requires more frequent dosing. If medical therapy is unsuccessful, patients may benefit from surgical decompression of the facial nerve. Autoimmune attack on myelinated motor nerves particularly of the lower extremities 25.
