Interview With a DO/MpH Pursuing his Passion

This interview is the latest in an Accepted blog series featuring  interviews with medical school applicants and students, offering readers a behind-the-scenes look at  top medical schools and the med school application process. And now, introducing Daniel Bral†¦ Accepted:  We’d like to get to know you! Where are you from? Where and what did you study as an undergrad? Daniel:  I was born and raised in Los Angeles California. True LA boy! I attended Yeshiva University for my undergraduate education and majored in Sociology and Talmudic Law. For my Masters of Science I attended Georgetown and earned a Masters in Physiology and Biophysics with a concentration in Complementary and Alternative Medicine. Now I am in my third year of medical school at Nova Southeastern University. Accepted:  Can you share 3 fun facts about yourself? Daniel:   1. I speak 4 languages; English was my third language. 2. I played water polo in high school. 3. My favorite color is neon orange. Accepted:  What motivated you to pursue a career in medicine? Daniel:  It’s been my lifelong dream and aspiration. I think the ObGyn must have been my inspiration as I was born because it’s all I have ever really loved and been this passionate about. However, surviving cancer definitely deepened that desire as I experienced the successes and failures of medicine, which only further motivated and inspired me. Being able to one day help change the form and shape of medicine is something that I know will be part of my legacy. Furthermore, I can’t think of a more noble and humbling profession as medicine. It’s truly a privilege to be on this road. Accepted:  You are doing a dual DO/MPH. Why did you choose this program? What is your favorite thing about that program? Is there anything you’d change? Daniel:  I have a clear dream and goal for what I envision and desire for my future career, life, and legacy to look like. Pursuing the DO/MPH seemed like a natural step in that direction. The Masters of Public Health degree is giving me perspectives and frameworks of healthcare and medicine beyond the walls of the clinic and hospital and larger in scope than one patient at a time. One of my favorite aspects of this path is that I am able to utilize portions of my brain that are not utilized often in the pursuit of medicine, which is a really nice break and yet you feel productive and less guilty about not studying for med school. An additional draw to pursuing the dual degree as opposed to earning the degree after completing my medical degree is the immense MPH tuition subsidy that is offered to the dual degree DO/MPH students. Accepted:  How did you your role as Chairman of the Young Peoples Advisory Committee for Teen Cancer America come about? Daniel:  I have been involved with all sorts of different leadership activities and committees over the years but, I am very active within the cancer community. Most recently becoming a strong voice in the teen and young adult cancer community, both as a cancer survivor as well as the Chairman of the Young People’s Advisory Committee of Teen Cancer America. However, I originally started my advocacy in the cancer realm 8 years ago as one of the first ‘angels’ in Imerman Angels, a 1-1 support organization for cancer patients internationally. After college, I was asked to serve as the president of an advisory board at UCLA to establish the first designated teen-young adult cancer program in the nation, the UCLA Daltrey/Townshend Teen and Young Adult Cancer Program. After working with Teen Cancer America in that role, I was asked by the Executive Director on behalf of their Board to take on the Chairmanship of the national survivor advisory committee for the organiz ation. The organization, Teen Cancer America, was founded in America by The Who band members Roger Daltrey and Pete Townshend in response to a similar organization they established in the United Kingdom, the Teenage Cancer Trust. Both of these organizations have the mission of establishing a place in medicine for the forgotten and overlooked demographic of teen and young adult cancer survivors (survivorship being defined from the point of diagnosis). These teens and young adults don’t truly fit in the clown and balloon decorated pediatric wards nor in the white washed and institutional rooms of adult oncology. Medically they are different than both groups, socially they are unique, and most poignantly, developmentally in a vastly different universe than either of those groups. Recognizing these differences Teen Cancer America and The Teenage Cancer Trust are internationally paving the way for this new specialty in medicine, Teen and Young Adult Hematology/Oncology, by working with National Cancer Institute-Comprehensive Cancer Centers across the nation to establish physical wards designated for teen and young adults and specially trained medical and supportive teams to run these programs. Accepted:  Looking back at the med school application process, what would you say was your greatest challenge? How would you advise other applicants who may be experiencing similar challenges? Daniel:  Looking back my greatest struggle was trying to force things that werent meant to be, not being honest with myself, and rushing a delicate process. Taking stock of who you are as a whole person and applicant is really important. Its hard to accept that some programs will only judge you based on a standardized score or based on one flaw or weakness you have and seemingly completely ignore the string components of your candidacy. My greatest piece of wisdom for myself and others as we embark and continue along the arduous yet immensely rewarding path of medicine is to (1) trust the universe and (2) remain persistent. I reconsidered medicine multiple times, asking myself if this is really meant to be and if I am really cut out for medical school. I always ended up coming back to medicine in my theoretical job pursuits; I realized that medicine is honestly my one true passion. I remained steadfast and persistent and didnt allow people to tell me to give up and I knew I would earn an acceptance to medical school. The pieces fell where they were supposed to. I ended up at the school that I believe was truly best for me and it was all because I put some trust into the universe that new would work out for the best for me. And I did it. I am in my third year, loving it, and working hard and succeeding. Accepted:  What has been the biggest unexpected challenge you have faced since starting med school? Daniel:  My biggest unexpected challenge during medical school has been being far from family. Since the age of 16/17 I have mostly been living away from home in Los Angeles. I started my collegiate years with a year abroad for religious studies in Israel, followed by 3 years of dual-enrollment in New York for college, then Washington DC for my graduate studies and now Fort Lauderdale/Miami for medical school. Throughout all those moves I really didn’t have any qualms about being away from home and family; it was always a matter-of-fact and part of life. However, reaching medical school and going through the first couple years, the drastic increase in dedication to medicine and my studies and classes and exams, left me at times desperately wishing I had family or someone to take care of other aspects of my life. Catching bronchitis or having a episode of varicella zoster during finals isnt easy without family around, and I learned that the hard way. Accepted:  Post med school what are your plans? Do you know what kind of medicine you want to go into? Daniel:  Im excited to be joining the ranks of medical professionals in the very near future! In terms of the specialty that I want to pursue, I have ideas of what I am interested in, but I am keeping an open mind as I go through my 3rd year of medical school!    You can follow Daniels experiences by following him on Twitter (@SDRBral).

Discrimination and Hispanics in America - 2057 Words

Discrimination and Hispanics in America SOC/120 May 20, 2012 Mary A Mc Gehee Discrimination and Hispanics in America Racial discrimination commonly refers to unfair or unequal behavior upon on individuals due to their race or ethnicity. Racism has been practiced for decades. Exerting superiority or supremacy over a race of individuals is the attempt of racial dominance. Despite the increasing population in the United States, Hispanic Americans find racial discrimination a reality in their lives. Migration rates have been on a dramatic climb over the past several decades resulting in a significant growth in diversity being experienced.

He explains that it is not uncommon for extended family members to live in the same household which is a break from the mainstream populations (personal communication, 2010). This is a traditional value that many attempt to hold on to desp ite the urbanization. It can be argued that this traditional value can be seen as segregation as it different from the mainstream and by default causes isolation from various neighborhoods. Language is another barrier that causes segregation. Often newly migrated Hispanics retain their native languages. English as the official language in the United States and teaching Spanish in elementary schools are often debated topics. I personally do not see what is wrong with learning a second language as a child. Spanish and French were always the second language options for me growing up and for my child. It is a great way to become diversified and mesh with the community. There are still some who would prefer not to mesh and thus the debate occurs. Racial redlining has many forms.

“The War On Drugs Is A Big Fucking Lie”. In Recent History,

â€Å"The war on drugs is a big fucking lie† In recent history, there has been much rhetoric surrounding the eradication of cross-border drug trafficking. The â€Å"war on drugs† was introduced in the 1970s by Nixon, who wanted to eliminate the drugs coming into the United States, since they were seen by him as a threat to our nation. Many laws have been enacted with the purpose keeping illicit drugs out of the United States, yet they do so through the use of nativist ideology, which upholds white supremacy by perpetuating the belief that those associated with Mexico are inherently criminals and must be kept out of the United States. Latin America is looked at as a corrupt place, teeming with drugs and criminals, that is tainting the wonderful and†¦show more content†¦Robert Garcia moved to Laredo before drug trafficking was rampant, and joined the Laredo PD. He worked with drug enforcement, and enjoyed the â€Å"local impact† (13). He ended up working w ith the DEA for six years, travelling the country in order to fight the war on drugs. Ultimately, he decided to return to Laredo, and worked in the homicide department. Through these two narratives, Slater explores the complexities of the â€Å"war on drugs† and how, ultimately, drug enforcement at the border does little to curb the crossing of drugs over the border. Throughout history, the United States has continuously perpetuated a system based on racism through its drug eradication policies. In 1973, Richard Nixon created the DEA, by consolidating â€Å"several drug-control agencies into one,† and prohibited opium, which at the time came mostly from Turkey. (73-74). Nixon brought about the â€Å"war on drugs,† which focused on eradicating illegal drugs from entering the United States, and essentially incited nativist attitudes to do so. There is a tendency in the United States to â€Å"idealize everything American and discount everything Mexican,† whi ch becomes increasingly relevant as Mexico is associated with drugs and crime (21).

Type 1 Diabetes Mellitus - 1548 Words

Type 1 diabetes mellitus is an autoimmune disease that results in insulin dependence due to failure of secretion of the hormone insulin by beta cells in the pancreas. Type 1 diabetes usually manifests in childhood, 20 years of age – the reason for which it was formerly termed juvenile diabetes, and is more prevalent in Caucasians then in any other ethnicity (Diabetes Basics, n.d.). The key to proper management is early detection, patient education, and most importantly patient compliance. The patient will commonly present with multiple symptoms, the most common are the 3 P’s – polyuria, polydipsia, and polyphagia.

The healthier the body the less lik ely the patient is to develop complications secondary to diabetes. Lifestyle also plays a huge role, diabetics that smoke and drink alcohol are also at a higher risk for complications. There are two categories of insulin – long-acting and rapid-acting, both are administered subcutaneously by injection and are measured in units. The long acting insulin - basal, detemir or glargine, has an onset of 3-4 hours and a duration of 24 hours. It is released slowly resulting in a constant effect over time (Insulin glargine, n.d.). Due to its long duration, long-acting insulin is generally administered every twenty-four hours, but it may be divided into two doses and administered every 12 hours. The dose is determined by the endocrinologist, or physician in charge of care, and is based on the patient’s needs. Rapid-acting insulin - bolus, aspart or lispro, has an onset of approximately 15 minutes with a duration of 3-4 hours (insulin lispro, n.d.). Rapid-acting insulin is admini stered directly before meals and dose varies according to blood glucose values and carbohydrate intake.

Among those available in Capture Options, the two highlighted below are worth examination. Setting Wireshark to capture packets in promiscuous mode If this feature is NOT checked, only PDUs destined for this computer will be captured. If this feature is checked, all PDUs d estined for this computer AND all those detected by the computer NIC on the same network segment (i. e. , those that â€Å"pass by† the NI C but are not destined for the computer) are captured. Note: The capturing of these other PDUs depends on the intermediary device connecting the end device computers on this network. As you use different intermediary devices (hubs, switches, routers) thro ughout these courses, you will experience the different Wireshark results. Setting Wireshark for network name resolution This option allows you to control whether or not Wireshark translates network addresses found in PDUs into names. Although th is is a useful feature, the name resolution process may add extra PDUs to your captured data perhaps distorting the analysis. There are also a number of other capture filtering and process settings available. Clicking on the Start button starts the data capture process and a message box displays the progress of this process. All contents are Copyright  © 1992–2007 Cisco Systems, Inc. All rights reserved. This document is Cisco Public Information. Page 3 of 12 As data PDUs are captured, the types and number are indicated in the message box The examples above show the capture of a ping process and then accessing a web page . When the Stop button is clicked, the capture process is terminated and the main screen is displayed . This main display window of Wireshark has three panes. All contents are Copyright  © 1992–2007 Cisco Systems, Inc. All rights reserved. This document i s Cisco Public Information. Page 4 of 12 The PDU (or Packet) List Pane at the top of the diagram displays a summary of each packet captured. By clicking on packets in this pane, you control what is displayed in the other two panes. The PDU (or Packet) Details Pane in the middle of the diagram displays the packet selected in the Packet List Pane in more de tail. The PDU (or Packet) Bytes Pane at the bottom of the diagram displays the actual data (in hexadecimal form representing the actual binary) from the packet selected in the Packet List Pane, and highlights the field selected in the Packet Details Pane . Each line in the Packet List corresponds to one PDU or packet of the captured d ata. If you select a line in this pane, more details will be displayed in the â€Å"Packet Details† and â€Å"Packet Bytes† panes. The example above shows the PDUs captured when the ping utilit y was used and http://www. Wireshark. org was accessed. Packet number 1 is selected in this pane. The Packet Details pane shows the current packet (selected in the â€Å"Packet List† pane) in a more detailed form. This pane show s the protocols and protocol fields of the selected packet. The protocols and fields of the packet are disp layed using a tree, which can be expanded and collapsed. The Packet Bytes pane shows the data of the current packet (selec ted in the â€Å"Packet List† pane) in what is known as â€Å"hexdump† style. In this lab, this pane will not be examined in detail. However, when a more in -depth analysis is required this displayed information is useful for examining the binary values and content o f PDUs. All contents are Copyright  © 1992–2007 Cisco Systems, Inc. All rights reserved. This document is Cisco Public Information. Page 5 of 12 The information captured for the data PDUs can be saved in a file. This file can then be opened in Wireshark f or analysis some time in the future ithout the need to re-capture the same data traffic again. The information displayed when a capture file is opened is the same as the original capture. You read "Transmission Control Protocol and Cisco Public Information" in category "Papers" When closing a data capture screen or exiting Wireshark you are pr ompted to save the captured PDUs. Click ing on Continue without Saving closes the file or exits Wireshark without saving the displayed captured data. Task 1: Ping PDU Capture Step 1: After ensuring that the standard lab topology and configuration is correct, launch Wireshark on a computer in a lab pod. Set the Capture Options as described above in the overview and start the capture process. From the command line of the computer, ping the IP address of another network connected and powered on end device on in the lab topology. In this case, ping the Eagle Server at using the command ping 192. 168. 254. 254. After receiving the successful replies to the ping in the command line window, stop the packet capture. Step 2: Examine the Packet List pane. The Packet List pane on Wireshark should now look something like this: Look at the packets listed above; we are interested in packet numbers 6, 7, 8, 9, 11, 12, 14 and 15. Locate the equivalent packets on the packet list on your computer. All contents are Copyright  © 1992–2007 Cisco Systems, Inc. All rights reserved. This document is Cisco Public Information. Pa ge 6 of 12 If you performed Step 1A above match the messages displayed in the command line window when th e ping was issued with the six packets captured by Wireshark . From the Wireshark Packet List answer the following: What protocol is used by ping? ________ICMP______________________ What is the full protocol name? ___Internet Control Message Protocol____ What are the names of the two ping messages? _____Echo Request____ _____Echo Reply____________________________________ Are the listed source and destination IP addresses what you expected? Yes / N o Why? ___________________________________ Answers may vary-Yes, the source address is my computer and the destination is the Eagle server Step 3: Select (highlight) the first echo request packet on the list with the mouse. The Packet Detail pane will now display something similar to: Click on each of the four â€Å"+† to expand the information. The packet Detail Pane will now be similar to: All contents are Copyright  © 1992–2007 Cisco Systems, Inc. All rights reserved. This document is Cisco Public Information. Page 7 of 12 As you can see, the details for each section and protocol can be expanded further. Spend some time scrolling through this information. At this stage of the course, you may not fully understand the information displayed but make a note of the information you do recognize. Locate the two different types of ‘Source† and â€Å"Destination†. Why are there two types? The Ethernet II shows the MAC addresses and the Internet Protocol shows the IP addresses What protocols are in the Ethernet frame? ___ eth:ip:icmp:data ___________________________________ As you select a line in the Packets Detail pane all or part of the information in the Packet Bytes pane als o becomes highlighted. For example, if the second line (+ Ethernet II) is highlighted in the Details pane the Bytes pane no w highlights the corresponding values. This shows the particular binary values that represent that information in the PDU. At this stage of the course, it is not necessary to understand this information in detail. Step 4: Go to the File menu and select Close. Click on Continue without Saving when this message box appears. Task 2: FTP PDU Capture Step 1: Start packet capture. Assuming Wireshark is still running from the previous steps, start packet capture by clicking on the Start option on the Capture menu of Wireshark. At the command line on your computer running Wireshark, enter ftp 192. 168. 254. 254 When the connection is established, enter anonymous as the user without a password. Userid: anonymous All contents are Copyright  © 1992–2007 Cisco Systems, Inc. All rights reserved. This document is Cisco Public Information.

When the file download is complete enter quit ftp quit 221 Goodbye. C:Documents and Settingsccna1 When the file has successfully downloaded, stop the PDU capture in Wireshark. Step 2: Increase the size of the Wireshark Packet List pane and scroll through the PDUs listed. Locate and note those PDUs associated with the file download. These will be the PDUs from the Layer 4 protocol TCP and the Layer 7 protocol FTP. Identify the three groups of PDUs associated with the file transfer. If you performed the step above, match the packets with the messages and prompts in the FTP command line window. The first group is associated with the â€Å"connection† phase and logging into the server . List examples of messages exchanged in this phase. Answers will vary- 1292 ftp [SYN], FTP 1292 [SYN, ACK], Response: 220 Welcome to the eagle -server FTP service, 1292 ftp [ACK], Request: User anonymous, Response: 331 Please specify the password, Request: Pass Locate and list examples of messages exchanged in the second phase that is the actual download request and the data transfer. Answers will vary- FTP Data: 1448 bytes, 1294 ftp-data [ACK], All contents are Copyright  © 1992–2007 Cisco Systems, Inc. All rights reserved. This document is Cisco Public Information. Page 9 of 12 The third group of PDUs relate to logging out and â€Å"breaking the connection†. List examples of messages exchanged during this process. Answers will vary- Request:QUIT, Response: 221 Goodbye, 1292 ftp [FIN, ACK], ftp 1292 [FIN, ACK] Locate recurring TCP exchanges throughout the FTP process. What feature of TCP does this indicate? __Send and receipt of data____________________________________________ Step 3: Examine Packet Details. Select (highlight) a packet on the list associated with the first phase of the FTP process. View the packet details in the Details pane. What are the protocols encapsulated in the frame? ____ Eth:ip:tcp:ftp-data ______________________________________ Highlight the packets containing the user name and password. Examine the highlighted portion in the Packet Byte pane. What does this say about the security of this FTP login process ? _____ Security isn’t very high because the name and password are visible. ___________ Highlight a packet associated with the second phase. From any pane, locate the packet containing the f ile name. The filename is: ___gaim-1. 5. 0. exe__________ Highlight a packet containing the actual file content -note the plain text visible in the Byte pane. Highlight and examine, in the Details and Byte panes, some packets exchanged in the third phase o f the file download. What features distinguish the content of these packets ? ____ A [FIN, ACK] is issued to close the connection. __________________ When finished, close the Wireshark file and continue without saving Task 3: HTTP PDU Capture Step 1: Start packet capture. Assuming Wireshark is still running from the previous steps, start packet capture by clicking on the Start option on the Capture menu of Wireshark. Note: Capture Options do not have to be set if continuing from previous steps of thi s lab. Launch a web browser on the computer that is running Wireshark. All contents are Copyright  © 1992–2007 Cisco Systems, Inc. All rights reserved. This document is Cisco Public Information. Page 10 of 12 Enter the URL of the Eagle Server of example. com or enter the IP address-192. 168. 54. 254. When the webpage has fully downloaded, stop the Wireshark packet capture. Step 2: Increase the size of the Wireshark Packet List pane and scroll through the PDUs listed. Locate and identify the TCP and HTTP packets associated with the webpage download. Note the similarity between this message exchange and the FTP exchange. Step 3: In the Packet List pane, highlight an HTTP packet that has the not ation â€Å"(text/html)† in the Info column. In the Packet Detail pane click on the â€Å"+† next to â€Å"Line-based text data: html† When this information expands what is displayed? ____HTML code for the web page__________________________ Examine the highlighted portion of the Byte Panel. This shows the HTML data carried by the packet. When finished close the Wireshark file and continue without saving Task 4: Reflection Consider the encapsulation information pertaining to captured network data Wireshark can provide. Relate this to th e OSI and TCP/IP layer models. It is important that you can recognize and link both the protocols represented and the protocol layer a nd encapsulation types of the models with the information provided by Wireshark. Task 5: Challenge Discuss how you could use a protocol analyzer such as Wireshark to: (1) Troubleshoot the failure of a webpage to download successfully to a browser on a computer. and (2) Identify data traffic on a network that is requested by users. Answers could vary-Wireshark could show when request for a web page failed due to incorrect URL. User traffic could be monitored to identify errors in source or destination.

Macbeth By William Shakespeare Essay Example For Students

Macbeth By William Shakespeare Essay In the play Macbeth by William Shakespeare, Lady Macbeth unconsciously uses Macbeth and others as a shield for guilt. When she wants something but doesnt have the guts to perform the task herself, she calls upon anyone but herself to do it. She thinks that this will erase her conscience of any guilt it has on it, but the shield is faulty. The first and most obvious of all places where this shield is placed is in the first two acts where Lady Macbeth is trying to convince her husband to kill King Duncan and become King of Scotland. She persuades by attacking Macbeths manliness,Was the hope drunkWherein you dressed yourself? Hath it slept since?And wakes it now, to look so green and paleAt what it did so freely? From this timeSuch I account thy love. Art thou afeardTo be the same in thine own act and valorAs thou art in desire? Wouldst thou have thatWhich thou esteemst the ornament of lifeAnd live a coward in thine own esteem,Letting ?I dare not wait upon ?I would,Like the poor cat I th adage?(I, vii, 39-49)By doing this, she manages to get Macbeth to kill King Duncan, however, in the end, she knows she is just as guilty as he is. Her guilt emerges in her visions of blood remaining on her hands,The Thane of Fife had a wife. Where isshe now? What, will these hands neer be clean? Nomore o that, my lord, no more o that. Yo u mar allwith this starting.(V, I, 44-47)Another less obvious place where Lady Macbeth uses others to shield her guilt is when Banquo is murdered. Both MacBeth and Lady MacBeth discuss their fear of Banquo knowing too much, and Lady MacBeth resolves to do nothing and leaves the chore up to her husband. After finding out about it, Lady MacBeth tells herself it wasnt her fault, but deep inside she knows it is just as much her as it is MacBeth who killed Banquo,Wash your hands. Put on your night-gown. Look not so pale. I tell you yet again, Ban-quos buried; he cannot come out on ?s grave.(V, I, 65-68)These examples show how Lady MacBeth used her husband to shield away the guilt. What she didnt expect was that it wouldnt work, and the blow of the guilt from murdering so many people strictly for power was too much for her weak shield. Emotionally she suffered and it drove her to talking her own life. She ineffectively tried to block off what was destined to come her way.
