By Ron Sherman MD, MSC, DTM&H This week I was asked about using maggot therapy for treating a tumor that eroded through the skin, causing a foul-smelling, necrotic draining wound. J. Contreras-Ruiz, S. Arroyo-Escalante, Fuentes-Suarez, J. Adominguez-Cherit, C. Sosa-de-Martinez, and E. Maravilla-Franco, “Maggot therapy and infection control in venous ulcers: a comparative study,” in Proceedings of the Symposium on Advanced Wound Care (SAWC ’05), San Diego, Calif, USA, April 2005. Some believe that the reason that no greater wound healing was seen in the maggot-treated arms was related to the study design, which used a “maggot debridement” protocol rather than a “maggot growth promotion” protocol 78). 379–383, 2007. 2000;10(3):91–94. 28, no. 6-7, pp. In Armstrong’s retrospective case-control study of lower extremity wounds in nonambulatory hospice patients 75), in which the researchers demonstrated significantly better infection control and fewer amputations required in the maggot-treated group, the difference in wound healing rates between the maggot-treated group (57% healed) and the control group (33% healed) was not statistically significant. July 21, 2014 February 25, 2020 Wound Care Advisor. F. A. S. Blake, N. Abromeit, M. Bubenheim, L. Li, and R. Schmelzle, “The biosurgical wound debridement: experimental investigation of efficiency and practicability,” Wound Repair and Regeneration, vol. A. S. Andersen, D. Sandvang, K. M. Schnorr et al., “A novel approach to the antimicrobial activity of maggot debridement therapy,” Journal of Antimicrobial Chemotherapy, vol. Clinical studies have demonstrated maggot therapy to be safe and effective in patients both with and without diabetes and for many problematic wounds, including pressure ulcers, venous stasis leg ulcers, wound bed preparation prior to surgical closure, and a variety of other traumatic, infectious, and vascular wounds 97). Exposing unstimulated human neutrophils to crude L. sericata salivary gland extract, Pecivova and colleagues 84) measured no effect on superoxide generation or myeloperoxidase (MPO) release. This has been shown at least for Staphylococcus aureus and Pseudomonas aeruginosa biofilm. 523–531, 2010. Insect Mol Biol. Larval therapy in wound management: a review. 47) demonstrated that the antimicrobial activity could be modified by exposure to microbial challenges (as is the case with many innate immunodefense peptides). More recent studies of larval alimentary secretions and excretions help scientists see just how these proteolytic enzymes fit into the context of debridement and wound healing, for they now know that alimentary secretions and excretions include a wide array of matrix metalloproteinases (MMPs), including at least the trypsin-like and chymotrypsin-like serine proteases, an aspartyl proteinase, and an exopeptidase-like matrix metalloproteinase, active across a wide pH range 24). Sterile maggots of the green bottle fly, Lucilia (Phaenicia) sericata, are used for MDT. They will not only inspect the wound you have seen, but look for any other possible sites of infestation as it is possible they are all over the cat's body. R. A. Sherman, “Maggot therapy for treating diabetic foot ulcers unresponsive to conventional therapy,” Diabetes Care, vol. 667–674, 2013. 26, no. E. R. Pavillard and E. A. Wright, “An antibiotic from maggots,” Nature, vol. A Handbook of Maggot-Assisted Wound Healing. Use a pair of tweezers to remove maggots that do not … Materials and Methods: This study was conducted as a clinical trial study with 90 eligible patients. In the end, death may occur. 93, no. Time to debridement differed significantly between the three groups (25.38). In another cohort of 18 diabetic subjects with 20 nonhealing neuropathic and neuroischemic foot ulcers, six wounds were treated with conventional therapy, six with maggot therapy, and eight with conventional therapy first and then maggot therapy 74). S. Chernysh, S. I. Kim, G. Bekker et al., “Antiviral and antitumor peptides from insects,” Proceedings of the National Academy of Sciences of the United States of America, vol. 3, pp. Experiments performed by Barnes et al 89) have demonstrated that the blowfly Lucilia sericata (Lucilia (Phaenicia) sericata) larvae excretions/secretions are able to inhibit bacteria growth in both stationary and exponential phases. Y. Nigam, A. Bexfield, S. Thomas, and N. A. Ratcliffe, “Maggot therapy: the science and implication for CAM part I—history and bacterial resistance,” Evidence-Based Complementary and Alternative Medicine, vol. 20, pp. Its beneficial effect was noted in diabetic foot and in destroying malignant tissue as well. The physical mechanics of maggot debridement 19) are readily apparent to anyone who has seen the larvae under the microscope. Wounds. Debridement refers to the removal of dead, damaged, or infected tissue to improve the healing potential of the remaining healthy tissue. Therefore, it should be no surprise that this maggot would be well-protected from infection. 2017;25(1):41–50. In fact, today, allantoin and urea are components of many cosmetics. Wound healing is classically described as 4 distinct but overlapping physiological phases of repair and rebuilding 17): With each phase, new cells are recruited into the area to perform the work, or cells already present alter their activity to secrete new cytokines or perform new duties, in response to changing conditions in the wound (bleeding, hypoxia, alterations in cytokine concentrations, etc.). The natural habitat of Lucilia sericata larvae is in rotting organic matter such as a corpse or excrement. Antimicrobial activity has been seen even against highly antibiotic-resistant bacteria 45) and against the protozoan Leishmania parasite 46). Z. Zhang, S. Wang, Y. Diao, J. Zhang, and D. Lv, “Fatty acid extracts from Lucilia sericata larvae promote murine cutaneous wound healing by angiogenic activity,” Lipids in Health and Disease, vol. was one of the first investigators to systematically demonstrate proteolytic activity of Lucilia sericata larval digestive enzymes. W. Robinson and V. H. Norwood, “Destruction of pyogenic bacteria in the alimentary tract of surgical maggots implanted in infected wounds,” The Journal of Laboratory and Clinical Medicine, vol. The practice is actually approved by the U.S. Food and Drug Administration as a prescription treatment. 15, no. He started maggot the… 11, Article ID e8071, 2009. 2, pp. 2, pp. 468, no. Patients were randomly assigned to two equal intervention and control groups. Controlled studies of maggot debridement are less common, but quite worthy of examination. 67, no. Evid Based Complement Alternat Med. The first controlled clinical trials were not begun until 1990 11), and it was not until 2004 that the U.S Food and Drug Administration (FDA) first granted marketing clearance to medicinal maggots (Medical Maggots; Monarch Labs, Irvine, CA) as a medical device 12).

In the study, maggots removed dead tissue from wounds faster than did standard surgical treatment. R. P. Hobson, “On an enzyme from blow-fly larvae (Lucilia sericata) which digests collagen in alkaline solution,” Biochemical Journal, vol. G. R. Erdmann and S. K. W. Khalil, “Isolation and identification of two antibacterial agents produced by a strain of Proteus mirabilis isolated from larvae of the screwworm (Cochliomyia hominivorax) (Diptera: Calliphoridae),” Journal of Medical Entomology, vol. 4, pp. This 10-day long clinical trial failed to show any significant difference in wound healing between the maggot debridement therapy arm (60% healed by day 10) and the control arm (34% healed by day 10), but it is generally believed that the lack of any significant difference may be due to the fact that this 10-day debridement study was much too short to detect any meaningful wound healing. When open wound healing is delayed despite the appropriate antibiotic treatment, especially in tropical or subtropical regions, myiasis should be suspected. Both factors increased the proliferation of fibroblasts stimulated by epidermal growth factor or interleukin 6. 202–204, 2010. But maggot therapy is one of the few highly effective methods of debridement which can safely and inexpensively be continued throughout the healing process, which may explain why it remains one of the methods of maintenance debridement best associated with faster wound healing. Wayman J, Nirojogi V, Walker A, Sowinski A, Walker MA. Early on, scientists believed that ingestion was the primary method by which the maggots cleared the wounds of infection 38), and subsequent researchers demonstrated that highly effective killing does indeed occur in the gut 39). WATCH: Worst Maggots in wounds coming out after removed and treatment. 132, no. Maggot therapy is a biotherapy in which live, disinfected maggots (fly larvae) are placed in a non-healing wound to eat the necrotic tissue and disinfect the wound. The median cost of treatment of the larval group was £78.64 compared with £136.23 for the control group. 338, article b773, 2009. For these reasons, maggot debridement was approved by the US Food and Drug Administration in 2004 21). 1067–1070, 2004. In this prospective clinical trial, Steenvoorde and colleagues 36) enrolled 64 patients with 69 chronic, necrotic wounds. Larvae are covered by minute spines which scrape along the wound base as the maggots crawl ab… Maggots are very good at eating dead tissue and cleaning out wounds, but we typically want to use medical-grade maggots in a clinical setting. All subjects received compression dressings, except during maggot debridement. The first thing you should do is very carefully cut the fur around the wound with a pair of scissors. 67–73, HMP Communications, Malvern, Pa, USA, 4th edition, 2007. One of the major advantages of MDT is that the … 60, no. 180, no. Does maggot help heal wound? Introduction.

Antibiofilm activity is valuable because biofilm is highly resistant to the penetration and successful activity of the human immune system and antibiotics. 635–639, 2002. The median time to debridement was 14 days with free-range larvae, 28 days with bagged larvae, and 72 days for the control arm. 2002;41(10):635–639. Evidence of maggot-induced tissue growth or wound healing now comes from both laboratory and clinical studies and also suggests both mechanical and biochemical pathways. 1334–1347, 2008. Within 2 weeks, maggot-treated wounds were left with only 7% necrotic tissue (0.9 cm²) compared to 39% necrotic tissue (3.1 cm²) in the control group and all maggot-treated wounds were completely debrided within 4 weeks, while most control wounds were still over 33% covered with necrotic tissue. A. Kruglikova and S. I. Chernysh, “Surgical maggots and the history of their use,” Entomology Review, vol. Larvae are covered by minute spines which scrape along the wound base as the maggots crawl about, loosening debris as does a surgeon’s rasper or file (Figure 1). Treatment consists of shaving the hair and removing in maggots, topical wound treatment and usually several weeks of oral antibiotic therapy. Depending on the size and depth of the wound, 50 to 1000 sterile maggots, about 24 to 48 hours old, are applied 2 to 4 times per week and left on for a period of 24 to 72 hours 94). However, with the appearance of antibiotic-resistant bacteria (eg, methicillin-resistant Staphyloccocus aureus), MDT has made a strong comeback.4 The dressing is finally covered with a simple absorbent pad held in place with adhesive tape or a bandage  7). 77), intended to evaluate maggot-induced wound healing in venous stasis ulcers. 12628–12632, 2002. Maggots are kept over the wound for cycles of about 48 hours; two 48-hour cycles are usually applied each week 8). F. L. Bowling, E. V. Salgami, and A. J. M. Boulton, “Larval therapy: a novel treatment in eliminating methicillin-resistant Staphylococcus aureus from diabetic foot ulcers,” Diabetes Care, vol. This will draw out maggots which have burrowed deeper in the wound. 9, article 24, 2010. Lucilia sericata larvae digest necrotic tissue and pathogens; they discriminate between necrotic and healthy (granulating) tissue. Keep the wound soaked for a half to an hour and carefully inspect it overtime. Wounds that really have quite a bit of dead tissue. Not all clinical studies of maggot-induced disinfection have demonstrated such positive results. 581–586, 1934. Telford et al. D. I. Pritchard, G. Telford, M. Diab, and W. Low, “Expression of a cGMP compatible Lucilia sericata insect serine proteinase debridement enzyme,” Biotechnology Progress, vol. 4, pp. The netting is then bunched up to create a cage for the larvae, placed on the wound, and secured to the hydrocolloid dressing by waterproof adhesive tape. 5418, pp. Their analysis revealed better outcomes in the free range group compared to the contained maggots group, despite the fact that the free range technique required fewer maggot applications and fewer total number of maggots per treatment. Once the maggots are removed, the underlying skin infection or other cause of infestation should be treated. Scientists control wound myiasis by carefully selecting the species and strain of fly, the species most commonly used is the blowfly Lucilia (Phaenicia) sericata, disinfecting the larvae, using special dressings to maintain the larvae on the wound, and integrating quality control measures throughout the process 2). 71–74, 1995. Parasitol Res. The cost effectiveness of larval therapy in venous ulcers. In this randomized controlled trial, the six wounds in the maggot debridement therapy arm were debrided faster than the six wounds in the control arm, with all of the maggot-debrided wounds completely debrided after just one 2-3-day treatment, compared to only 4 of the control wounds completely debrided after a month of therapy. During World War 1, William Baer, an orthopedic surgeon, noted the benefits of using maggots in compound fractures. Larval secretions also contain deoxyribonuclease (DNAse), able to degrade both microbial DNA and also human DNA in necrotic debris 28). 2, pp. Gently wipe away dead maggots that have worked to the surface of the wound 1. Both groups received routine treatments for chronic ulcers. Unfortunately, very few studies have compared free range with bagged maggots, though such a study could be a valuable mechanism for evaluating the relative importance of the maggot’s physical versus chemical activity 34). This will draw out and kill maggots that have burrowed deeply into the wound, as well as any maggots on the surface 1. The physical action of the maggot over the wound is a primary reason given by the FDA for classifying medicinal maggots as a medical device and not a simple drug. Dumville et al.’s 267-subject randomized controlled trial of maggot therapy for venous stasis wounds 60) did not demonstrate any significant difference between the time-dependent decreasing bacterial burden in maggot-treated patients versus control patients, nor any significant difference in the number of MRSA-colonized wounds that were cleared. J. Buchman and J. E. Blair, “Maggots and their use in the treatment of chronic osteomyelitis,” Surgery, Gynecology and Obstetrics, vol. What was particularly surprising, though, was the discovery that maggot alimentary secretions and excretions is capable of dissolving biofilm and inhibiting the growth of new biofilm 54). Wound healing may be trapped at any phase (or even while undergoing a combination of phases), but typically it is within the inflammatory phase: dead, infected debris may not be adequately removed from the wound bed, and/or it might not be possible for the body to eradicate the local infection, and/or the proteases and other destructive products of inflammation by clearing the newly formed cellular and extracellular matrix as fast as it is being laid down. The common maggots which are used for this medical therapy are maggots of certain flies such as Green Bottle Fly or Nothern Blow Fly. 129–134, 2012. Indeed, it has been shown that excretions/secretions from the blowfly Lucilia sericata (Lucilia (Phaenicia) sericata) exhibit potent, thermally stable, protease-resistant antibacterial activity against in vitro MRSA 3). "Maggot debridement therapy is typically used for chronic wounds. 119–125, 2009. J. W. Costerton, P. S. Stewart, and E. P. Greenberg, “Bacterial biofilms: a common cause of persistent infections,” Science, vol. 52, no. Soak the wound, which has been treated with saline solution or peroxide in turpentine-oil soaked gauze. 8, pp. Picking out maggots from the wound using forceps after applying local anesthesia is a common form of treatment. 455–466, 2010. 2007;61(3):488–493. Save my name, email, and website in this browser for the next time I comment. Clinical observations provided evidence for growth stimulation in chronic wounds 92). W. Robinson, “Stimulation of healing in non-healing wounds by allantoin occurring in maggot secretions and of wide biological distribution,” Journal of Bone and Joint Surgery, vol. Once they are located, the maggots will have to be manually extracted from the skin of the cat. Stuttgart: Thieme, 2004:93. Several comprehensive reviews have been published over the past decade 13), 14), 15). The wound is thereafter cleaned and bandaged. 3, no. Biopsies of maggot-treated wounds reveal profound angiogenesis 67). 85) monitored cyclic AMP (cAMP) in human neutrophils before and after exposure to L. sericata alimentary secretions and excretions and then again in human monocytes 86). G. Cazander, M. W. Schreurs, L. Renwarin, C. Dorresteijn, D. Hamann, and G. N. Jukema, “Maggot excretions affect the human complement system,” Wound Repair and Regeneration, vol. Apply a dusting of cornstarch to inspect any left maggots in the wound. 223–227, 2006. The average wound size (cm²) increased weekly during control therapy but decreased by over 20% per week with maggot therapy. Therefore, maggot-treated wounds tended to be larger (22 cm2 versus 14 cm²) and deeper (35% down to bone in the maggot therapy group; 8% in the control group). 23, no. The antibacterial potency of the medicinal maggot, Lucilia sericata (Meigen): variation in laboratory evaluation. J. C. Dumville, G. Worthy, J. M. Bland et al., “Larval therapy for leg ulcers (VenUS II): randomised controlled trial,” The British Medical Journal, vol. 30, no. 18, no. Several papers have described the utility of maggot debridement therapy 95), though there is only 1 randomized, specific Lucilia sericata clinical debridement trial using maggot therapy 96). 4, no. Addressing the on-going need for wound cleaning and disinfection is the paradigm behind “maintenance debridement,” and appears to be gaining support as an important strategy for treating wounds 82). None of the control wounds were debrided by more than 50%, even with 4 weeks of treatment. Many clinicians intuitively feel that faster debridement brings faster wound healing. Postgrad Med J. However people may describe them, we benefit a lot from these little creatures. Maggots and wound care. 3c. R. D. Wolcott, J. P. Kennedy, and S. E. Dowd, “Regular debridement is the main tool for maintaining a healthy wound bed in most chronic wounds,” Journal of Wound Care, vol. Several reasons may explain this, including the simple fact that the maggots may not expedite healing in any clinically meaningful way. Maggot debridement therapy is the real-time placement of maggots into a wound by health professionals for the treatment of diabetic ulcers or hard-to-heal wounds infected with antibiotic-resistant bacteria.

Masiero FS, Thyssen PJ. In a cohort of 63 patients with 92 pressure ulcers, followed for at least 8 weeks while receiving either standard wound care (as prescribed by the hospital’s wound care team), or maggot therapy (two 48- to 72-hour cycles per week), maggot-treated wounds were debrided four times faster than control wounds (0.8 cm²/week versus 0.2 cm²/week) 30). Some people may even use the word “maggot” as a derogatory term. New research published in the October issue of Clinical Infectious Diseases has found that maggots are useful in treating deep wounds without increasing the risk of further infection… A. Using remittance spectroscopy to evaluate patients before and after maggot therapy, Wollina and colleagues 68) found that vascular perfusion and tissue oxygenation surrounding the wound actually increased following maggot therapy. G. Cazander, M. C. van de Veerdonk, C. M. J. E. Vandenbroucke-Grauls, M. W. J. Schreurs, and G. N. Jukema, “Maggot excretions inhibit biofilm formation on biomaterials,” Clinical Orthopaedics and Related Research, vol. For these reasons, maggot debridement was approved by the US Food and Drug Administration in 2004 90). 9, pp. 90, no. When reviewing their patients, Steenvoorde and Jukema 58) also found decreased colony counts of gram positive organisms following maggot therapy, but they found increased counts of gram negatives. Brown, A. Horobin, D. G. Blount et al., “Blow fly Lucilia sericata nuclease digests DNA associated with wound slough/eschar and with Pseudomonas aeruginosa biofilm,” Medical and Veterinary Entomology, vol. Armstrong et al. Of the three described actions of maggot therapy, debridement (physical and chemical) is the best studied. 4, pp. Mechanisms of maggot-induced wound healing: what do we know, and where do we go from here?. Valachová and colleagues 50) demonstrated that lucifensin expression was increased in response to microbial ingestion only in the fat body; lucifensin was expressed in the salivary glands throughout the larval period and not significantly affected by microbial ingestion. Each maggot is capable of removing 25 mg of necrotic material from the wound within just 24 hours 18). The physical movement of the maggot over the wound, plowing the tissue and spreading its alimentary secretions and excretions as it goes, contributes significantly to the debridement effort. M. Bradley, N. Cullum, and T. Sheldon, “The debridement of chronic wounds: a systematic review,” Health Technology Assessment, vol. Even more antimicrobial molecules are likely to be discovered in the coming years. In this study population, the probability of healing may have had more do to with the patients’ underlying circulatory compromise, malnutrition, and poor physiologic health than with the treatments rendered. The application of sterile Lucilia sericata larvae to an infected nonhealing wound results in the removal of necrotic tissue, disinfection, rapid elimination of infecting microorganisms, and enhancement of the healing process 4). 219–227, 2001. 13, pp. 916–917, 1957. Using maggots in wound care: Part 1. Complications. 4592, pp. I. Valachová, J. Bohová, Z. Pálošová, P. Takáč, M. Kozánek, and J. Majtán, “Expression of lucifensin in Lucilia sericata medicinal maggots in infected environments,” Cell and Tissue Research, vol. 17, pp. 10, pp. This study revealed significantly fewer days of antibiotics compared to controls, over a 6-month observation period, indicating that the patients were cleared of their infection faster and remained infection free longer. Twelve patients with sloughy venous ulcers were randomized to receive either larval therapy or the control hydrogel therapy. With recent advances in cellular biology and chemistry, we now know that maggot alimentary secretions and excretions stimulates the proliferation of fibroblasts 64) and endothelial tissue (unpublished data), increases angiogenesis 65), and enhances fibroblast migration over model wound surfaces 66). Platelets, neutrophils, and monocytes/macrophages are among the first cells recruited to the young wound when they remain beyond their usefulness and contributed to an unending inflammatory phase that can interfere with or even prevent the wound from moving forward in the healing process. 1, no. 2, pp. Maggot therapy is a simple and successful method for cleansing infected and necrotic wounds. In medical care, maggots are intentionally put on an open wound. 835–841, 1981. 65, no. Ophthalmic myiasis – maggot … DNAse may play an important role not only in debridement but also in inhibiting microbial growth and biofilm. Four and eight-week healing rates have repeatedly been shown to be accurate surrogates for wound healing in general, although they have not been accepted as substitutes for complete wound closure in clinical trials. The BBC was less optimistic, saying that maggots may not have the miracle healing properties that have been claimed. 8, pp. 12–14, 2010. 39, no. 91–94, 2000. 1–78, 1999. When no longer needed, the cells undergo apoptosis and are removed or engulfed by other cells (i.e., macrophages). The maggots can be removed by forceps. Maggot therapy is administered by applying sterilized fly larvae to the wound at a density of 5 to 8 per cm² 6). Scientific evidence for all three actions – debridement (cleaning of debris), disinfection, and hastened wound healing – has been slow in coming. Certainly, the use of maggots in wound care isn’t a novel idea. 97–101, 2004. 2017;29(12):367-373. https://www.medscape.com/viewarticle/891517. This is not an uncommon question, and it touches upon several important elements of biotherapy, as well as palliative wound care in general. V. Cerovský, J. Zdárek, V. Fucík, L. Monincová, Z. Voburka, and R. Bém, “Lucifensin, the long-sought antimicrobial factor of medicinal maggots of the blowfly Lucilia sericata,” Cellular and Molecular Life Sciences, vol. 95, no. M. J. Maggot secretions have recently been found to affect the activity of these cells in ways that decrease inflammation. My advice to you would be to seek out a wound … This both protects the skin from irritation by the maggot’s proteolytic enzymes and forms the base of the adhesive dressing. Experiments performed by Barnes et al 20) have demonstrated that the blowfly Lucilia sericata (Lucilia (Phaenicia) sericata) larvae excretions/secretions are able to inhibit bacteria growth in both stationary and exponential phases. R. A. Sherman, K. Y. Mumcuoglu, M. Grassberger, and T. I. Tantawi, “Maggot therapy,” in Biotherapy—History, Principles and Practice: A Practical Guide to the Diagnosis and Treatment of Disease Using Living Organisms, M. Grassberger, R. A. Sherman, O. S. Gileva, C. M. H. Kim, and K. Y. Mumcuoglu, Eds., pp. 26) demonstrated that some of the maggot’s proteases are resistant to human wound protease inhibitors. If this paradigm is correct, it would explain why maggot therapy continued beyond the point of gross debridement has been associated with faster wound healing 83). A maggot infestation on a living vertebrate host is called myiasis. Maggot debridement therapy is used to treat and heal certain chronic wounds that have extensive areas of dead tissue. google_ad_client: "ca-pub-9759235379140764", The eggs hatch and form maggots. The use of maggots has become increasingly important in the treatment of nonhealing wounds, particularly those infected with the multidrug-resistant pathogen, methicillin-resistant Staphylococcus aureus (MRSA). 2, pp. At least one of these chymotrypsin-like proteases has now been produced recombinantly in Escherichia coli 27) and could soon enter clinical trials as a purified debriding enzyme. Kawabata et al. Greenberg hypothesized that antimicrobial compounds might be produced in the gut by symbiotic microbes such as Proteus mirabilis, and, in 1986, Erdmann and Khalil identified and isolated two antibacterial substances (phenylacetic acid and phenylacetaldehyde) from the Proteus mirabilis that they isolated from the gut of a related blowfly larva: Cochliomyia hominivorax 40). A cohort of 63 patients with 92 pressure ulcers was prospectively followed for at least 8 weeks while receiving either standard wound care (as prescribed by the hospital’s wound care team) or maggot therapy (two 48- to 72-hour cycles per week) 71).
